matrix bounds check to detect any PNG pixel outside the dimensions derived from
anime_type and return AnimeError::IncorrectSize with the appropriate dimensions
instead of silently skipping it. Restore the AnimeError import and preserve

- Around line 13-14: Rename the public AnimeError::Png variant to a
decoder-agnostic name matching its ImageError source, update all constructors,
pattern matches, and references including GIF decoding, and document this
breaking public API change in the crate changelog.
In `@rog-anime/src/gif.rs`:

inside the loop. Rename the local binding image to anime_image to avoid
shadowing the image crate.
- Around line 118-136: Update the frame-processing loop to avoid reusing the
persistent AnimeDiagonal matrix and skipping transparent pixels: construct a
fresh matrix for each decoded frame, remove the stale alpha-based continue and

rog-anime/src/diagonal.rs:59-63. Replace each inline brightness calculation,
widen before dividing, and preserve alpha consistently, deciding explicitly how
GIF frame alpha should be handled rather than hardcoding 1.0.
- Around line 478-479: Add coverage for 16-bit PNG handling in the image
conversion path around img.to_rgba8(), using a suitable 16-bit fixture and
asserting the expected rounded channel values; alternatively, explicitly
document that image 0.25.9’s rounding behavior is intentional. Keep existing

But the code still does:matrixis built once at line 105 and never cleared, and line 121 skips any pixel the decoder resolved to non-opaque.

63-65: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winYou are still quietly throwing pixels in the bin.
The matrix size comes from
anime_type. If a user hands you a PNG bigger than that, this bounds check drops every out-of-range pixel and returns a half-drawn image with no error, no log, nothing. The user then stares at a truncated animation and blames the hardware.
AnimeError::IncorrectSize(u32, u32)exists precisely for this. Use it. This was raised on an earlier commit and the code has not moved.🐛 Proposed fix

105-136: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winThis function still composites frames twice, and the second pass is wrong.
image::AnimationDecoder::into_frameshands you a complete, already-composited RGBA canvas for every frame. That was the whole point of the migration. This code then does its own compositing on top:
- Line 105 builds
matrixonce, outside the loop. Line 139 callsinto_data_buffer(&self), which borrows, somatrixsurvives into the next iteration carrying the previous frame's pixels.- Lines 121-124 skip any pixel the decoder resolved to non-opaque. That pixel keeps whatever an earlier frame put there.
Result: transparent GIFs smear and ghost. The comment on line 122 is reasoning about the old
gifcrate sub-rectangle API and is now simply false.Pick one owner of compositing. The decoder already did it, so let it: fresh canvas per frame, write every pixel.

42-61: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winStill silently cropping oversized PNGs, and the doc comment above now lies.
Lines 43-45 promise "dimensions up to the max for the laptop model". The bounds guard on line 58 does not enforce that promise, it hides the violation. Feed in a 200x200 PNG and you get a quietly cropped image with zero diagnostics.
AnimeError::IncorrectSize(u32, u32)exists for precisely this case. Compare withfrom_diagonal_gifinrog-anime/src/gif.rs, which returnsPixelGifWidth/PixelGifHeighton the same class of input. Two decoders in one crate, two different answers to "the image is too big". Pick one.This was raised on an earlier commit and the code did not move.
🐛 Proposed fix
-use crate::error::Result; +use crate::error::{AnimeError, Result};let mut matrix = AnimeDiagonal::new(anime_type); + let expected_h = matrix.1.len() as u32; + let expected_w = matrix.1.first().map_or(0, |r| r.len()) as u32; + if rgba.width() > expected_w || rgba.height() > expected_h { + return Err(AnimeError::IncorrectSize(expected_w, expected_h)); + } + for (x, y, px) in rgba.enumerate_pixels() { let x = x as usize; let y = y as usize; let v = Pixel::from(px).color as f32; - if y < matrix.1.len() && x < matrix.1[y].len() { - matrix.1[y][x] = (v * bright) as u8; - } + matrix.1[y][x] = (v * bright) as u8; }🤖 Prompt for AI Agents

132-163: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftThe persistent canvas plus the alpha skip is old-decoder logic. It ghosts frames now.
image::AnimationDecoder::into_framescomposites for you. Every yielded frame is a complete canvas, and a pixel the decoder deliberately resolved to transparent is a real result, not a "no data here" marker. Both loops then do the compositing a second time by hand:
matrix(line 130) andanime_image(line 207) live outside the frame loop and are never cleared.- The
px.0[3] != 255skip on lines 142 and 226 means a transparent pixel keeps whatever the previous frame wrote there.So any GIF with transparency smears. The comment "should be t but not in some gifs? What, ASUS, what?" is stale reasoning from the
gifcrate era and should leave with the code that needed it. While you are there:frame.left()/frame.top()are 0 for composited frames, so lines 137-138 and 221-222 add nothing but the illusion of sub-rectangle handling.This was raised on an earlier commit and the code did not move.
🐛 Proposed fix for `from_diagonal_gif`
- let mut matrix = AnimeDiagonal::new(anime_type); - let mut frames = Vec::default(); let (frames_iter, _, _) = decode_gif(file_name)?; for frame in frames_iter { let frame = frame?; let wait: Duration = frame.delay().into(); - let left = frame.left() as usize; - let top = frame.top() as usize; let buffer = frame.buffer(); + // `into_frames` yields fully composited canvases, so start clean. + let mut matrix = AnimeDiagonal::new(anime_type); for (x, y, px) in buffer.enumerate_pixels() { - if px.0[3] != 255 { - // should be t but not in some gifs? What, ASUS, what? - continue; - } let tmp = matrix.get_mut(); - let y = y as usize + top; - let x = x as usize + left; + let y = y as usize; + let x = x as usize; if y >= tmp.len() { return Err(AnimeError::PixelGifHeight(tmp.len())); } if x >= tmp[y].len() { return Err(AnimeError::PixelGifWidth(tmp[y].len())); }🐛 Proposed fix for `from_gif`
for frame in frames_iter { let frame = frame?; let wait: Duration = frame.delay().into(); - let left = frame.left() as usize; - let top = frame.top() as usize; let buffer = frame.buffer(); for (x, y, px) in buffer.enumerate_pixels() { - if px.0[3] != 255 { - // should be t but not in some gifs? What, ASUS, what? - continue; - } - let px_x = x as usize + left; - let px_y = y as usize + top; + let px_x = x as usize; + let px_y = y as usize; if px_x >= width || px_y >= height { continue; }Also applies to: 202-248

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
GifDecoder::new gets no limits, so an attacker-supplied GIF sizes your allocations.
Lines 112-113 read the decoder dimensions and hand them straight to from_gif, which then allocates width * height Pixel values (12 bytes each). A GIF header declaring 65535x65535 costs about 51 GB before a single frame is decoded. The header is cheap to forge; the allocation is not. ImageDecoder::set_limits exists exactly for this, and you already imported the trait on line 7.
This was raised on an earlier commit and the code did not move.
