feat: rebrand to MMD PDF, single corporate theme, and remove original text under an edit
- Services/PdfRedactText.cs: strip text whose origin falls inside a CoverAnnotation from the page content stream at save time, hooked into PdfBurn.DrawAnnotationsIntoDoc. Fixes edited values staying recoverable by text extraction. - Themes/MMD.xaml replaces all thirteen themes; picker and accent strip removed; no dark mode. - Rename KillerPDF -> MMD PDF across code, resources, packaging and locale strings; new icon. - Remove the upstream author credit and the in-app install button.

### Added
|

- Shift+mouse wheel now scrolls wide pages horizontally, using the same scrolling path as a tilt wheel (#209, thanks Ryokoxx).
|
||||
- Ctrl+B, Ctrl+I and Ctrl+U now bold, italicize and underline while you are editing a text box. They were listed in the shortcuts for weeks without ever being wired up.
|
||||
- Hungarian OCR completes the twelve-language OCR catalog, so every language available for the KillerPDF interface now has a matching downloadable recognition model.

### Changed
|
||||
- The text annotation toolbar now uses a deliberate two-row layout: font above size, text color above fill color, and text opacity above fill opacity. It is taller but substantially narrower, with each lower control aligned beneath its corresponding upper control instead of leaving Fill Opacity stranded on an accidental wrapped row.

KillerPDF 1.7.4 keeps the convenience of one portable download while installing as a normal multi-file application, cutting initial startup time substantially. This release also fixes annotation rotation, form fields on comma-decimal locales, installation scope, and a range of viewer, dialog, and localization problems. Hungarian localization and page image export are included as well.

- KillerPDF now remains one portable download while installing as a normal multi-file application. The portable EXE carries one compressed, verified payload and cleans up its temporary files after use; installed shortcuts launch the inner app directly, avoiding Costura extraction and reducing measured first startup by about 40% on the development machine (#189, thanks ags1234). The new package is also roughly 34% smaller than the previous woven EXE.

|

- Documents opened from Explorer get keyboard focus immediately, so arrows and Page Up/Down work without clicking the window first, and horizontal scrolling from a touchpad or tilt wheel now pans the document (#196, thanks Subjuntivos).
|

- Double-click text editing now maps PostScript font names (ArialMT, TimesNewRomanPSMT, Helvetica) to the installed Windows family, so edited text keeps its font instead of falling back to the default (#187, thanks fo-bo).

### Added
|
||||
- Transform can now correct trapezoidal perspective distortion in pages photographed at an angle. Turn on perspective correction, drag four corner handles onto the photographed page outline, and Apply converts that quadrilateral into a straight rectangular page at the full transform resolution. The correction composes with rotation, deskew, scaling, and flipping in the same operation (#175, thanks 1mk3r).
|
||||
- KillerPDF now registers a `killerpdf://` link handler for the current user, laying the app-side foundation for the planned Chrome extension. A `killerpdf://open?url=...` link can hand a public HTTPS PDF to KillerPDF whether the app is closed or already running; downloads are size-limited and rejected unless their contents begin as a PDF. The registration refreshes itself when the executable moves.
|
||||
- Open and Save dialogs now return to the last folder successfully used for that kind of operation, unless the caller deliberately supplies another starting folder. The places rail also brings in the user's pinned Windows Explorer Quick Access folders alongside KillerPDF's own editable pins, while avoiding duplicate entries (#178, thanks sheafitzek).

- Fit Width and Fit Page are now remembered as the preferred fit for subsequently opened PDFs, so users on smaller screens no longer have to switch from Fit Page every time, thanks Thomas.
|
||||
- Owner-restricted encrypted PDFs with malformed linearization tables now pass through KillerPDF's tolerant PDFium cleanup instead of being retried through PdfSharp's fragile read-only parser. This fixes the array-index error that prevented the Fritzbox 4060 manual from opening, thanks Thomas.
|
||||
- Reopening a PDF no longer reapplies a raw zoom saved for a different window or monitor size, which could make the document appear enormous or tiny. KillerPDF keeps the saved page and view mode but fits the document to the current window, with Grid returning to a predictable three-column layout. Perspective correction's corner handles now retain their drag capture across child controls and release reliably, and applying the correction immediately redraws the edited page even when the current zoom does not change.

The first selected line extends left from the starting point and the last line extends right to the ending point, while left-to-right documents keep their existing behavior. Direction is detected per line, so mixed-language pages work without a document-wide setting (#170, thanks playerbhr).
|
||||
- Installing KillerPDF for everyone now registers its PDF handler for the whole computer instead of writing it into the elevated administrator's personal registry. Every account can now find KillerPDF in Open With and Default apps, with the shared registration pointing at the Program Files copy; each user still chooses their own PDF default (#176, thanks adeit).

|
||||
- The keyboard-shortcut list now uses the available window width instead of squeezing both halves into a narrow fixed card. Longer translated descriptions have room to remain visible, wrap cleanly on smaller windows, and sit level with the shortcut text in both columns (#177, thanks Mr-Update).
|
||||
- The mouse wheel now moves the file picker's multi-column list horizontally, so folders and files beyond the right edge can be reached without dragging the bottom scrollbar. The folder tree's wheel works too, scrolling vertically normally and horizontally while Shift is held. The shared picker fix applies to Open, Save, image import, signatures, certificates, and every other file-selection flow; icon and details views keep their normal vertical wheel scrolling.
|
||||
- Text annotations, highlights, stamps, ink, and filled form fields already stored in a PDF now appear in KillerPDF and survive printing, flattening, image export, page transforms, thumbnails, and repair rasterization (#141, thanks zenfas). PDFium does not paint annotation appearance streams unless explicitly requested, so every pixel-producing path silently omitted them. Enabling Docnet's annotation flag was not safe because it creates and destroys a form-fill environment while its page remains in use, corrupting PDFium state and crashing on a later native call. KillerPDF now renders through its direct PDFium layer, owns the form callback memory for its full native lifetime, paints both ordinary annotations and interactive widget appearances, then immediately closes the form, page, and one-shot document together. The reporter's five-page D&D Beyond file from #179 now exports and flattens with its filled values and multiline fields intact, without the native teardown crash (#179, thanks hsnopi).
|
||||
- Annotations and stamps now save in the right position on PDFs that already carry a native page rotation when they are first opened (#169, thanks terada-d). The 1.7.0 fix read only KillerPDF's temporary rotation map, but that map is not populated until a page operation performs a temporary save and reload, so annotating an already rotated file and saving it immediately still treated the page as unrotated. Burn-in now falls back to the page's own `/Rotate` value, every newly opened document clears the previous document's temporary rotation map, and saving removes a malformed CropBox that extends outside its MediaBox instead of preserving contradictory portrait and landscape dimensions. Tests cover the reported invalid page boxes and preservation of a valid inset crop.

|

- Filled form fields now generate complete appearance streams, including the required stream length, multiline layout, and WinAnsi text encoding (#180, thanks Ryokoxx). This keeps entered values visible and readable in PDF viewers that strictly validate field appearances, resolving the damaged-file warning, missing line breaks, and replaced punctuation reported in #179 (#179, thanks hsnopi).
|
||||
- Double-clicking bold or italic PDF text to edit it no longer turns the replacement into regular text (#182, thanks fo-bo). PDF text usually carries its face styling inside the embedded font name, such as `Helvetica-BoldOblique`, rather than as separate bold and italic properties. The detector cleaned those suffixes off to find the font family, then explicitly reset both style flags before opening the editor, so the formatting was lost before the first keystroke. Font detection now separates the family from its bold and italic face, applies both to the live edit box, and carries them into the replacement annotation when it is committed. Focused tests cover subset font names and regular, bold, italic, and combined faces.
|
||||
- Clicking a page no longer crashes with "'∞' is not a valid value for property 'Height'" (#181, thanks lachlan-00). The page click rebuilds every annotation and form overlay, and malformed geometry could reach a WPF Width or Height property without being checked. WPF refuses NaN and infinity, so one bad form rectangle or a legacy saved signature with zero canvas dimensions took down the whole viewer during the redraw. Form rectangles and every sized annotation are now checked before they reach WPF; invalid form widgets are skipped, old signature dimensions fall back to the standard canvas size, and the render layer has a final guard for malformed persisted annotations.

|
||||
|
||||
### Added
|
||||
- Split pane: F10 shows two documents side by side in one window. Each pane is a card of its own, and the focused one carries an accent ring so it is obvious which pane the toolbar, sidebar and page list are acting on. Click either pane to move focus. The boundary between them has a handle on each side: grab the left one to size the left pane or the right one to size the right. Neither pane can be squeezed below a readable width. F10 closes the split again, and the rail button's icon follows along: a pane pushed out will open, while one pulled back in will close. Each pane has its own tab strip, but the shared toolbar, sidebar, and page list follow whichever pane has focus. Drag a tab from one pane's strip to the other to move it across. On a maximized or snapped window, F10 splits the space evenly instead of squeezing the second pane to its minimum.
|
||||
- Every Open and Save dialog is KillerPDF's own now, instead of the stock Windows one: the same themed window as the rest of the app, with a places rail, a folder tree, list/icon/details views, sortable columns, pinnable folders and recent locations. That covers opening and saving PDFs, merging, extracting pages, flatten, image export, image import, signature and certificate picking, OCR output and the zip export - including picking several files at once where that applies. Shared with the other Killer Tools apps, so the file dialog looks and behaves the same across the family.
|
||||
- Install for everyone on this computer. The Install button on the portable badge now opens a confirmation with two choices: add a desktop shortcut (on by default, as before) and install for all users (off by default because it needs an administrator). An all-users install puts KillerPDF in Program Files with a Start menu entry for every account, and removes the per-user copy so there is a single entry in Add/Remove Programs rather than two. Declining the administrator prompt leaves the app running portable exactly as it was. A `/silent` switch performs the machine-wide install with no interface for winget, Chocolatey, and RMM deployment. This matches Killendar and KillerShell. PDF file associations are still registered only for the current account; an all-users install does not change what PDFs open with for anyone else.

- "Confirm before opening links" is back, on the About card beside the recent-files toggle. It asks before a link in a PDF opens in your browser, and it is off by default so links stay immediate unless you want the check. The prompt's own "Don't ask again" now simply switches the same option off, so the two can no longer disagree. The setting had no home after the Settings panel was dissolved; About is where the safety and data-hygiene controls live.

- The Settings panel and its gear are gone: every section moved to where the thing it configures lives, matching the rest of the Killer Tools apps. Theme and language are flyouts on new rail buttons (below the night-mode moon, with a ? button for the shortcuts overlay); the theme flyout stays open across a pick so themes can be compared.
|
||||
- Toolbar appearance is a right-click menu on the toolbar itself, and it is two independent choices now instead of one list of five: icon size (small/large) and text placement (none/beside/under/text only) - so large icons with captions is finally possible. Fresh installs default to large icons with text underneath; existing installs keep their setting. Ctrl+Shift+1-6 pick the options directly.
|
||||
- Internal: the codebase has been reorganized into the Killer Tools family layout - document logic in service classes, the About/CLI/OCR/search features behind controllers, the window partials under Shell/. Every moved function is verbatim and no behavior change is intended; the repo root now holds only the entry files.
|
||||
- New app icon. The old document icon with the red bar across the bottom now marks PDF *files*, so a KillerPDF window and a PDF sitting in a folder are no longer the same picture. Explorer caches icons aggressively, so a PDF may keep showing the old art until the cache refreshes.

All the new shortcuts are on the F1 overlay, in all ten languages.
|
||||
- Internal: the tab strip and split-pane drag/focus model were rewritten to match KillerShell's implementation, the family's reference for both, replacing the original hand-built version.

- The sidebar's left/right choice sits at the bottom of the sidebar's right-click menu, which now opens from any part of the sidebar; Ctrl+Shift+B flips the side, pairing with Ctrl+B's collapse.

||||
- The sidebar's page list fades into the background at its top and bottom edges while there are pages scrolled past them - the same treatment KillerShell's folder tree and the killerpdf.net sidebar use. Each fade ramps in over its own height as a row slides under it, so nothing pops, and neither shows when the list is flush at that end.

### Fixed
|
||||
- Japanese and other non-Latin text no longer saves as empty boxes (#168, thanks terada-d). The editor is a Windows text box, which quietly borrows glyphs from any installed font, so what you type always looks right; the save path resolved a single font and wrote a box for every character that font lacked. Two things were wrong. Nearly every CJK font on Windows ships as a collection file (Yu Gothic, MS Gothic, Meiryo, YaHei, JhengHei), and the save path could not read collections at all. Even picking a Japanese font by hand did not help. Nothing checked whether the chosen font could carry the text either. KillerPDF now reads collection fonts, and when your font cannot render something it picks one that can, preferring the same faces Windows itself falls back to. Your own font is always used when it covers the text. This affects Bengali, Korean, Chinese, Thai, Arabic and Indic scripts too, and applies to page numbers and watermarks as well as placed text. Embedded fonts are subset, so a line of Japanese adds tens of KB to the file rather than the whole typeface. If nothing installed can draw a character, KillerPDF now says so when the text is placed and lists the unsupported characters. This rare case can happen when one box contains two non-Latin scripts or the PC has no font for the requested script.

Shortcuts were matched by key position, which is a US-layout assumption: on a German keyboard "?" lives on Shift+ss and "=" on Shift+0, so Ctrl+? and Ctrl+= pressed keys the app was not listening for, and the extra Shift broke the match a second time. Zoom and the shortcuts overlay now respond to the key that TYPES the character, whatever position it occupies, so they work on German, French, Nordic and other layouts rather than being fixed one at a time. The shortcuts overlay also prints the spelling that is right for the keyboard in use instead of always showing the US one.
|
||||
- Annotations and stamps are no longer burned into the wrong frame on a rotated page (#169, thanks terada-d for a report that diagnosed it down to the line). A page's rotation is deliberately kept outside the working document, so the canvas you draw on is in the rotated frame while the save path writes into the page's own unrotated one - and the save path was never told the angle. Anything placed on a quarter-turned page came out rotated 90 degrees from where you put it, offset, and scaled on swapped axes, which also squeezed text boxes narrow enough to wrap after almost every character. Stamps had the same fault, so page numbers and watermarks landed in the wrong corner and disagreed with their own preview. The rotation now travels with the burn, in the editor and in the background flatten that print uses.
|
||||
- The app-size readout parked itself on the status bar. Rolling the wheel over the logo wrote "App size N%" into the footer behind a short hold, which existed so the chrome resize could not stomp the message with its own page and zoom status the same frame. When that hold expired nothing repainted the line, so the readout stayed put until the next page change, tool switch or open happened to write over it. It is transient now. Each notch rewrites the readout and restarts a five second timer, and the status line goes back to what it was showing before the first notch when the timer expires. The hold is unchanged and still only covers the same-frame stomp. If something else wrote a status after the hold lapsed the restore is skipped, so a real message is never replaced by a stale one.

|

|
||||
### Added
|
||||
- Remove Password in the Save dropdown (#149, thanks dmantisk): saves the open document back over the original with its password protection dropped - available whenever the file needed a password (or carried owner restrictions) to open. KillerPDF already strips encryption at open time because the editing pipeline cannot modify encrypted files in place, so every save has always written an unprotected PDF; this makes that behavior a visible, deliberate action, and regular saves of a previously protected file now say so in the status bar instead of dropping the password silently. In all ten languages.

### Changed
|
||||
- Tool hotkey remap - the digits again mirror the toolbar left to right, with Shapes slotted in (breaks some muscle memory; the letter keys are unchanged): V = Select (the Photoshop / Illustrator / Figma convention; its old digit went to Text), 1 = Text, 2 = Highlight, 3 = Line, 4 = Shapes, 5 = Draw, 6 = Image, 7 = Signature, 8 = Crop, 9 = Transform, 0 = Stamp. The toolbar buttons reorder to match (Highlight now before Line, Shapes between Line and Draw), and the Shapes tool has a keyboard shortcut for the first time. The shortcuts overlay (both views), tooltips, and the help page follow.

- Keyboard view in the shortcuts overlay (F1): a visual keyboard with every bound key lit and color-coded by category. Toggle LIST / KEYBOARD in the header (the choice sticks), click a layer or hold Ctrl / Shift / Alt to preview it, and hover a lit key for its action. Follows the active theme and language.
|
||||
- More conventions from the big viewers: Home / End jump to the first / last page, Ctrl+1 / Ctrl+2 / Ctrl+3 set actual size / fit width / fit page, and the Menu key or Shift+F10 opens the right-click menu at the current selection (keyboard accessibility).
|
||||
- Japanese OCR language (`jpn`), downloadable on demand like the rest - the OCR language list now covers the same nine languages as the interface.
|
||||
- Command-line batch mode: `KillerPDF.exe --batch-resave <input> <output> [--log report.csv] [--quiet]` resaves a single PDF or a whole folder tree headlessly through the standard open/save pipeline, with per-file OK/SKIP/FAIL reporting. Built for the validation harness.

F2 now renames the selected bookmark in the Outline panel, the Windows rename convention. Settings gained F9 (Ctrl+, also works, the VS Code / Windows Terminal convention), and F3 / Shift+F3 step to the next / previous search match from anywhere (F3 opens search when it isn't). Pressing a dialog shortcut while the shortcuts overlay is open dismisses the overlay first. The shortcuts overlay and the help page keyboard map follow.

### Fixed
|
||||
- Resaving a PDF no longer reduces its PDF/A conformance. The PDF library (PdfSharpCore, MIT) is now vendored under third_party/ with six patches: no Producer/Creator stamping into an imported document's Info dictionary, no /ModDate rewrite at open, no transparency /Group injected into every page, stream /Length now always matches the spec's byte count (empty streams included), boolean values written as the spec's lowercase true/false keywords, and the debug-only verbose file layout removed. Found by the new veraPDF validation harness across a 2,900-file corpus.

- Intermittent hard crash (native heap corruption) while scrolling or clicking through a document, most visible on annotation-heavy pages: KillerPDF's direct PDFium calls (link extraction, encryption stripping) could land at the same moment as a background page render inside PDFium, which is single-threaded. Every direct call now holds the same lock the render path uses. Diagnosed from a 1.6.3 crash dump showing two threads inside PDFium at once.

Saves now strip dead signature values and the matching /Perms entry; the signature fields themselves are kept.

- Saving over the open file failed with "being used by another process" on PDFs whose pages carry annotations but no links readable by the primary parser (typically fillable forms): the cached PDFium link handle was holding the file open.
