** WIP | ** WIP | ||
** Canvas.ToBlob is used in FX OS Gallery APP. This bug is trying to improve the processing time of JPEG encoding from canvas to JPEG. OpenMAX JPEG is not working in Qualcomm solutions. So try to use OpenCL to accelerate JPEG encoding/decoding. MAIDAI can support OCL. This bug could fully utilize the multiple cores HW for encoding/decoding. I focused on tracing JPEG source code now. | ** Canvas.ToBlob is used in FX OS Gallery APP. This bug is trying to improve the processing time of JPEG encoding from canvas to JPEG.

** debug | |||
** BufferUnrotate() received a inconsistent parameters - byteWidth and stride , such that the index it used to manipulate the image buffer will out of its size. Typically byteWidth((buff width) * bpp) should >= stride, however the bpp is incorrectly given with 32-bits(should be 16-bits) when crash occurs, while the stride was calculated with 16-bits bpp. Need to figure out why bpp is not right. | |||

** debug | |||
** By QA's comment, it can be reproduced with the same steps of bug#970007. However most crashes I tried is not belong to this bug, will solve bug#970007 first, and then back to this bug. | |||
