[3] Added a compile-time macro (LIBJPEG_TURBO_VERSION) that can be used to
check the version of libjpeg-turbo against which an application was compiled.
+[4] Added new RGBA/BGRA/ABGR/ARGB colorspace extension constants (libjpeg API)
+and pixel formats (TurboJPEG API), which allow applications to specify that,
+when decompressing to a 4-component RGB buffer, the unused byte should be set
+to 0xFF so that it can be interpreted as an opaque alpha channel.
+
1.1.90 (1.2 beta1)
==================
libjpeg-turbo includes extensions that allow JPEG images to be compressed
directly from (and decompressed directly to) buffers that use BGR, BGRX,
-RGBX, XBGR, and XRGB pixel ordering. This is implemented with six new
+RGBX, XBGR, and XRGB pixel ordering. This is implemented with ten new
colorspace constants:
JCS_EXT_RGB /* red/green/blue */
JCS_EXT_BGRX /* blue/green/red/x */
JCS_EXT_XBGR /* x/blue/green/red */
JCS_EXT_XRGB /* x/red/green/blue */
+ JCS_EXT_RGBA /* red/green/blue/alpha */
+ JCS_EXT_BGRA /* blue/green/red/alpha */
+ JCS_EXT_ABGR /* alpha/blue/green/red */
+ JCS_EXT_ARGB /* alpha/red/green/blue */
Setting cinfo.in_color_space (compression) or cinfo.out_color_space
(decompression) to one of these values will cause libjpeg-turbo to read the
At run time, attempting to use these extensions with a version of libjpeg
that doesn't support them will result in a "Bogus input colorspace" error.
+When using the RGBX, BGRX, XBGR, and XRGB colorspaces during decompression, the
+X byte is undefined, and in order to ensure the best performance, libjpeg-turbo
+can set that byte to whatever value it wishes. If an application expects the X
+byte to be used as an alpha channel, then it should use JCS_EXT_RGBA,
+JCS_EXT_BGRA, JCS_EXT_ABGR, or JCS_EXT_ARGB. When these colorspace constants
+are used, the X byte is guaranteed to be 0xFF, which is interpreted as opaque.
+
+Your application can check for the existence of the alpha channel colorspace
+extensions at compile time with:
+
+ #ifdef JCS_ALPHA_EXTENSIONS
