devashish	4d7ba50dc7	JPGLoader: Move bogus JPEGs to a different directory	2020-11-29 16:22:04 +01:00
Devashish Jaiswal	2a3166e523	JPGLoader: Check existence of Huffman tables in scan header segment (#3442) ... DC and AC table IDs read in the scan header segment weren't validated against the IDs of Huffman tables read in the DHT segment. This caused an OOB read when a Huffman table was accessed using the ID read in the scan header segment. Furthermore, the decoder now replaces the old DC or AC table if a redefinition has been found prior to the scan header. Fixes #3439.	2020-09-10 11:20:04 +02:00
Devashish	8b71b839fa	LibGfx+LibWeb: Add JPEG decoder and integrate with LibWeb ... This patch adds support for JPEG decoding. The JPEG decoder is capable of handling standard 2x1 horizontal, 2x1 vertical and quartered chroma subsampling. The implemented Inverse DCT performs with a decent speed. As of interchange formats, since we tend to ignore the metadata in APPn markers, the decoder can handle any format compatible with JFIF, which includes EXIFs and sometimes WebMs too. The decoder does not support progressive JPEGs yet.	2020-06-23 13:51:19 +02:00
