Lucas CHOLLET	dc9e783608	LibGfx/JPEG: Remove the ensure_bounds_okay function ... This function has probably been added when we weren't as good with error propagations as we are now. We can safely remove it and let future calls to `read` fail if the file is corrupted. This can be tested with the following bytes (already used in 9191829a): ffd8ffc000000800080ef701101200ffda00030100	2023-04-03 09:19:15 -04:00
Lucas CHOLLET	3f9c5af553	LibGfx/JPEG: More support for scans with a single component ... Introduced in 2c98eff, support for non-interleaved scans was not working for frames with a number of MCU per line or column that is odd. Indeed, the decoder assumed that they have scans that include a fabricated MCU like scans with multiple components. This patch makes the decoder handle images with a number of MCU per line or column that is odd. To do so, as in the current decoder state we do not know if components are interleaved at allocation time, we skip over falsely-created macroblocks when filling them. As stated in 2c98eff, this is probably not a good solution and a whole refactor will be welcome. It also comes with a test that open a square image with a side of 600px, meaning 75 MCUs.	2023-03-25 21:31:21 +01:00

Lucas CHOLLET	f66de973ff	LibGfx/JPEG: Replace a FIXME with some explanations ... Calling the `ycbcr_to_rgb` function still looks unsuitable for this usage, but it does the job correctly.	2023-03-22 08:57:51 +01:00
