User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:20.0) Gecko/20100101 Firefox/20.0 Build ID: 20130401133152 Steps to reproduce: Open the image attached in this bug report with firefox. Image description : - Bitmap using BITMAPV5HEADER - BI_BITFIELDS compression - 32 bits per pixel storage - bitmasks : RedMask; : 0xff000000 GreenMask; : 0x00ff0000 BlueMask; : 0x0000ff00 AlphaMask; : 0x000000ff Additional information : - Tested with a 64 bit Linux distribution (Fedora 17) with firefox 20.0 - The image is correctly oppened with GIMP, gthumb, eog, ... - A quick look at src/image/src/BMPFileHeaders.h show that there is no alpha in the bitFields struct. - Also, in src/image/decoders/nsBMPDecoder.cpp doesn't parse alpha bitfields of bitmap v5. If I interpret that correctly, it looks like that it's just not implemented. Actual results: The image appear blue with a black disc on the center. Expected results: The image is black with a transparent disc on the center.
