JPEG decoding requires additional space in the bitmap buffer beyond what is needed for the decoded pixel data. Provide a way to estimate how much overhead is needed. The actual overhead is sizeof(struct jpeg) + decode_buf_size, where the latter depends on the image size and JPEG encoding used. From my testing decode_buf_size is normally pretty small (under 5 KiB) but looking at the code it could be large in some cases, primarily with large images, so 32 KiB seems to be a decent compromise. Someone who knows better about JPEG should pick a better value if that's too big. Using a constant is obviously not the most accurate but it seems to be the simplest option for retrofitting to existing code. Change-Id: I573b0abb8ca2d79e43f185010487f07226edb793 |
