Vincent Politzer	cabbfcfd7e	fix: Use HalPowerManager for battery percentage (#1005) ... ## Summary The introduction of `HalGPIO` moved the `BatteryMonitor battery` object into the member function `HalGPIO::getBatteryPercentage()`. Then, with the introduction of `HalPowerManager`, this function was moved to `HalPowerManager::getBatteryPercentage()`. However, the original `BatteryMonitor battery` object is still utilized by themes for displaying the battery percentage. This PR replaces these deprecated uses of `BatteryMonitor battery` with the new `HalPowerManager::getBatteryPercentage()` function. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

cottongin	ad282cadfe	fix: Align double FAST_REFRESH image rendering with upstream PR #957 ... Reorder refresh branches so image+AA pages always use the double FAST_REFRESH technique instead of occasionally falling through to HALF_REFRESH when the refresh counter expires. Image pages no longer count toward the full refresh cadence. Remove experimental Method B toggle (USE_IMAGE_DOUBLE_FAST_REFRESH / displayWindow).

cottongin	c8ba4fe973	fix: Port upstream CSS-aware image sizing (PR #1002) ... Parse CSS height/width into CssStyle for images and use aspect-ratio- preserving logic when CSS dimensions are set. Falls back to viewport-fit scaling when no CSS dimensions are present. Includes divide-by-zero guards and viewport clamping with aspect ratio rescaling. - Add imageHeight field to CssStyle/CssPropertyFlags - Parse CSS height declarations into imageHeight - Add imageHeight + width to cache serialization (bump cache v2->v3) - Replace viewport-fit-only image scaling with CSS-aware sizing Co-authored-by: Cursor <cursoragent@cursor.com>	2026-02-19 14:21:31 -05:00

Uri Tauber	3e2c518b8e	fix: Crash (Load access fault) when indexing chapters containing characters unsupported by bold/italic font variants (#997) ... ## Summary * **What is the goal of this PR?** I flashed the last revision before commit f1740dbe, and chapter indexing worked without any crashes. After applying f1740dbe, the same chapter consistently triggered a device reboot during indexing. The affected chapter contains inline equation images surrounded by styled (bold/italic) text that includes special math/symbol characters. ## Additional Context Prior to f1740dbe, both `getTextAdvanceX()` and `getSpaceWidth()` always measured text using `EpdFontFamily::REGULAR`, regardless of the actual style. Commit f1740dbe improved correctness by passing the active style so spacing is calculated using the actual bold/italic font variant. However, bold and italic variants have narrower Unicode coverage than the regular font. When a character exists in the regular font but not in the selected styled variant, `pdFont::getGlyph()` returns `nullptr`. The updated measurement functions did not check for this and immediately dereferenced the pointer: `width += font.getGlyph(cp, style)->advanceX; // nullptr->advanceX` Because `advanceX` is located at byte offset 2 within `EpdGlyph`, dereferencing a null pointer caused the CPU to attempt a load from address `0x00000002`, resulting in a RISC-V: Load access fault MCAUSE = 5 MTVAL = 2 ## Fix Added null-safety checks to both `getTextAdvanceX()` and `getSpaceWidth()`, following the same pattern used in the rendering path: If the glyph is missing in the selected style → fall back to the replacement glyph. If the replacement glyph is also unavailable → treat the character as zero-width. This preserves the improved style-correct spacing while preventing crashes. No behavioral changes occur for characters that are supported by the selected font variant. --- ### AI Usage Did you use AI tools to help write this code? _**< YES >**_ I encounter this bug while testing 1.1.0 RC. I pasted the serial log to Claude, which identify the bug and fixed it. I can confirm now the chapter in question is indexed and loaded correctly.	2026-02-20 03:45:26 +11:00

cottongin	0fda9031fd	fix: Use double FAST_REFRESH for dithered letterbox sleep covers ... Replace HALF_REFRESH with double FAST_REFRESH technique for the BW pass when dithered letterbox fill is active. This avoids the e-ink crosstalk and image corruption that occurred when HALF_REFRESH drove large areas of dithered gray pixels simultaneously. Revert the hash-based block dithering workaround (bayerCrossesBwBoundary, hashBlockDither) back to standard Bayer dithering for all gray ranges, since the root cause was HALF_REFRESH rather than the dithering pattern itself. Letterbox fill is now included in all three render passes (BW, LSB, MSB) so the greyscale LUT treats letterbox pixels identically to cover pixels, maintaining color-matched edges.

The problem was that word width calculations were including any negative X overhang, and combined with a space before the word, that can lead to an inconsistently large space. ## Additional Context Screenshots of some problematic text: | In CrossPoint 1.0 | With this change | | -- | -- | | <img src="https://github.com/user-attachments/assets/87bf0e4b-341f-4ba9-b3ea-38c13bd26363" width="400" /> | <img src="https://github.com/user-attachments/assets/bf11ba20-c297-4ce1-aa07-43477ef86fc2" width="400" /> | --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

jpirnay	aa7c0a882a	feat: Add 4bit bmp support (#944) ... ## Summary * What is the goal of this PR? - Allow users to create custom sleep screen images with standard tools (ImageMagick, GIMP, etc.) that render cleanly on the e-ink display without dithering artifacts. Previously, avoiding dithering required non-standard 2-bit BMPs that no standard image editor can produce. ( see issue #931 ) * What changes are included? - Add 4-bit BMP format support to Bitmap.cpp (standard format, widely supported by image tools) - Auto-detect "native palette" images: if a BMP has ≤4 palette entries and all luminances map within ±21 of the display's native gray levels (0, 85, 170, 255), skip dithering entirely and direct-map pixels - Clarify pixel processing strategy with three distinct paths: error-diffusion dithering, simple quantization, or direct mapping - Add scripts/generate_test_bmps.py for generating test images across all supported BMP formats ## Additional Context * The e-ink display has 4 native gray levels. When a BMP already uses exactly those levels, dithering adds noise to what should be clean output. The native palette detection uses a ±21 tolerance (~10%) to handle slight rounding from color space conversions in image tools. Users can now create a 4-color grayscale BMP with (imagemagic example): ``` convert input.png -colorspace Gray -colors 4 -depth ``` --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

jpirnay	c8ddb6b61d	fix: Fix kosync repositioning issue (#783) ... ## Summary * Original implementation had inconsistent positioning logic: - When XPath parsing succeeded: incorrectly set pageNumber = 0 (always beginning of chapter) - When XPath parsing failed: used percentage for positioning (worked correctly) - Result: Positions restored to wrong locations depending on XPath parsing success - Mentioned in Issue #581 * Solution - Unified ProgressMapper::toCrossPoint() to use percentage-based positioning exclusively for both spine identification and intra-chapter page calculation, eliminating unreliable XPath parsing entirely. ## Additional Context * ProgressMapper.cpp: Simplified toCrossPoint() to always use percentage for positioning, removed parseDocFragmentIndex() function * ProgressMapper.h: Updated comments and removed unused function declaration * Tests confirmed appropriate positioning * __Notabene: the syncing to another device will (most probably) end up at the current chapter of crosspoints reading position.

Bram Schulting	a8f0d63693	feat: Tweak Lyra popup UI (#768) ... I want to preface this PR by stating that the proposed changes are subjective to people's opinions. The following is just my suggestion, but I'm of course open to changes. The popups in the currently implemented version of the Lyra theme feel a bit out of place. This PR suggests an updated version which looks a bit more polished and in line with the rest of the theme. I've also taken the liberty to remove the ellipsis behind the text of the popups, as they made the popup feel a bit off balance (example below). With the applied changes, popups will look like this.  The vertical position is (more or less) aligned to be in line with the sleep button. I'm aware the popup is used for other purposes aside from the sleep message, but this still felt like a good place. It's also a place where your eyes naturally 'rest'. The popup has a small 2px white outline, neatly separating it from whatever is behind it. Initially I started out worked off the Figma design for the Lyra theme, which [moves the popups](https://www.figma.com/design/UhxoV4DgUnfrDQgMPPTXog/Lyra-Theme?node-id=2011-19296&t=Ppj6B2MrFRfUo9YX-1) to the bottom of the screen. To me, this results in popups that are much too easy to miss:  After this, I tried moving the popup back up (to the position of the sleep button), but to me it still kinda disappeared into the text of the book:  Inverting the colors of the popup made things stand out the perfect amount in my opinion. The white outline separates the popup from what is behind it.  This looked much better to me. The only thing that felt a bit off to me, was the balance due to the ellipsis at the end of the popup text. Also, "Entering Sleep..." felt a bit.. engineer-y. I felt something a bit more 'conversational' makes at all feel a bit more human-centric. But I'm no copywriter, and English is not even my native language. So feel free to chip in! After tweaking that, I ended up with the final result: _(Same picture as the first one shown in this PR)_  * Figma design: https://www.figma.com/design/UhxoV4DgUnfrDQgMPPTXog/Lyra-Theme?node-id=2011-19296&t=Ppj6B2MrFRfUo9YX-1 --- While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

CaptainFrito	a8a89e35b8	feat: Lyra Icons (#725) ... /!\ This PR depends on https://github.com/crosspoint-reader/crosspoint-reader/pull/732 being merged first Also requires the https://github.com/open-x4-epaper/community-sdk/pull/18 PR Lyra theme icons on the home menu, in the file browser and on empty book covers     - Added a function to the open-x4-sdk renderer to draw transparent images - Added a scripts/convert_icon.py script to convert svg/png icons into a C array that can be directly imported into the project. Usage: ```bash python ./scripts/convert_icon.py 'path/to/icon.png' cover 32 32 ``` This will create a components/icons/cover.h file with a C array called CoverIcon, of size 32x32px. Lyra uses icons from https://lucide.dev/icons with a stroke width of 2px, that can be downloaded with any desired size on the site. > The file browser is noticeably slower with the addition of icons, and using an image buffer like on the home page doesn't help very much. Any suggestions to optimize this are welcome. --- While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

cottongin	426a978e44	feat: silent pre-indexing with configurable status bar indicator ... Port PR #979's silent pre-indexing and add an Indexing Display setting (Popup / Status Bar Text / Status Bar Icon) so users can choose how indexing feedback is shown. Silent pre-indexing runs on text-only penultimate pages when a status bar option is selected, with a standard requestUpdate to clear the indicator. Image pages skip silent indexing to avoid e-ink grayscale pipeline conflicts; the normal popup handles those transitions. Direct chapter jumps always show the original small popup regardless of setting. Co-authored-by: Cursor <cursoragent@cursor.com>	2026-02-19 09:30:29 -05:00

Maik Allgöwer	103fac2ee1	feat: Basic table support (#980) ... I've been reading "Children of Time" over the last days and that book, annyoingly, has some tabular content. This content is relevant for the story so I needed some really basic way to at least be able to read those tables.

jpirnay	c4e3c244ea	feat: Add 4bit bmp support (#944) ... ## Summary * What is the goal of this PR? - Allow users to create custom sleep screen images with standard tools (ImageMagick, GIMP, etc.) that render cleanly on the e-ink display without dithering artifacts. Previously, avoiding dithering required non-standard 2-bit BMPs that no standard image editor can produce. ( see issue #931 ) * What changes are included? - Add 4-bit BMP format support to Bitmap.cpp (standard format, widely supported by image tools) - Auto-detect "native palette" images: if a BMP has ≤4 palette entries and all luminances map within ±21 of the display's native gray levels (0, 85, 170, 255), skip dithering entirely and direct-map pixels - Clarify pixel processing strategy with three distinct paths: error-diffusion dithering, simple quantization, or direct mapping - Add scripts/generate_test_bmps.py for generating test images across all supported BMP formats ## Additional Context * The e-ink display has 4 native gray levels. When a BMP already uses exactly those levels, dithering adds noise to what should be clean output. The native palette detection uses a ±21 tolerance (~10%) to handle slight rounding from color space conversions in image tools. Users can now create a 4-color grayscale BMP with (imagemagic example): ``` convert input.png -colorspace Gray -colors 4 -depth ``` --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

Zach Nelson	448a77f02b	perf: Remove hasPrintableChars pass (#971) ... ## Summary **What is the goal of this PR?** `hasPrintableChars` does a pass over text before rendering. It looks up glyphs in the font and measures dimensions, returning early if the text results in zero size. This additional pass doesn't offer any benefit over moving straight to rendering the text, because the rendering loop already gracefully handles missing glyphs. This change saves an extra pass over all rendered text. Note that both `hasPrintableChars` and `renderChar` replace missing glyphs with `glyph = getGlyph(REPLACEMENT_GLYPH)`, so there's no difference for characters which are not present in the font. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

Usage: ```bash python ./scripts/convert_icon.py 'path/to/icon.png' cover 32 32 ``` This will create a components/icons/cover.h file with a C array called CoverIcon, of size 32x32px. Lyra uses icons from https://lucide.dev/icons with a stroke width of 2px, that can be downloaded with any desired size on the site. > The file browser is noticeably slower with the addition of icons, and using an image buffer like on the home page doesn't help very much.

Bram Schulting	f16c0e52fd	feat: Tweak Lyra popup UI (#768) ... ## Summary I want to preface this PR by stating that the proposed changes are subjective to people's opinions. The following is just my suggestion, but I'm of course open to changes. The popups in the currently implemented version of the Lyra theme feel a bit out of place. This PR suggests an updated version which looks a bit more polished and in line with the rest of the theme. I've also taken the liberty to remove the ellipsis behind the text of the popups, as they made the popup feel a bit off balance (example below). With the applied changes, popups will look like this.  The vertical position is (more or less) aligned to be in line with the sleep button. I'm aware the popup is used for other purposes aside from the sleep message, but this still felt like a good place. It's also a place where your eyes naturally 'rest'. The popup has a small 2px white outline, neatly separating it from whatever is behind it. ### Alternatives considered and rationale behind proposal Initially I started out worked off the Figma design for the Lyra theme, which [moves the popups](https://www.figma.com/design/UhxoV4DgUnfrDQgMPPTXog/Lyra-Theme?node-id=2011-19296&t=Ppj6B2MrFRfUo9YX-1) to the bottom of the screen. To me, this results in popups that are much too easy to miss:  After this, I tried moving the popup back up (to the position of the sleep button), but to me it still kinda disappeared into the text of the book:  Inverting the colors of the popup made things stand out the perfect amount in my opinion. The white outline separates the popup from what is behind it.  This looked much better to me. The only thing that felt a bit off to me, was the balance due to the ellipsis at the end of the popup text. Also, "Entering Sleep..." felt a bit.. engineer-y. I felt something a bit more 'conversational' makes at all feel a bit more human-centric. But I'm no copywriter, and English is not even my native language. So feel free to chip in! After tweaking that, I ended up with the final result: _(Same picture as the first one shown in this PR)_  ## Additional Context * Figma design: https://www.figma.com/design/UhxoV4DgUnfrDQgMPPTXog/Lyra-Theme?node-id=2011-19296&t=Ppj6B2MrFRfUo9YX-1 --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.
