Example resultAa — A small example of your colors.
How it works
Read the first two 32-bit values as big-endian dimensions, followed by depth, color, compression, filter and interlace bytes.
The example decodes to 1920×1080, 8-bit RGBA, with no interlace.
Limits
Paste payload bytes only. This checks IHDR field combinations, not the chunk CRC or image data.
