From echelon's review of #2607: - A GIF's LZW data now bounds its first frame's own width x height, not the logical screen's, so a valid GIF with a small first frame on a larger screen imports. - A canvas the file's data leaves mostly blank (a GIF screen larger than its first frame, or an RLE BMP larger than its runs could cover at 255 pixels per 2 bytes) still costs its whole size in from_decoder, so it is limited to 4 MP (SPARSE_MAX_PIXELS) and refused before the decoder allocates it. Densely coded canvases keep the max_pixels limit. Tests: a 64-byte RLE BMP declaring 2001 x 2000 or 32000 x 32000 is refused ("mostly blank"); the RLE BMP that ends early still opens at 2000 x 2000; a GIF with a 1 x 1 first frame opens on a 2000 x 2000 screen and is refused on a 32767 x 32767 one. The first three fail without this change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PtjHGt5gnCHXgLt4NbGorf
