2011-11-08Support for transparency in 32bit bitmaps on color targets.Thomas Martitz
This uses the alpha blending capabilities introduced with anti-aliased fonts to draw bitmaps with transparency information. The bmp loader is extended to read this information (pass FORMAT_TRANSPARENT in format). The alpha information will be used when drawing the bitmap. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30937 a1c6a512-1295-4272-9138-f99709370657

2009-01-08cleanup for core-file-in-pluginlib compilation:Andrew Mahone
wrapper C files in pluginlib renamed to the same name as the core files they wrap pluginlib-only init functions for resize and bmp moved into the wrapper files, and declared in the associated header files API() macro removed entirely, in favor of a core-only header file that redefines core function names to use a plugin_api pointer some unnecessary uses of PLUGIN in apps/recorder/bmp.c removed git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19712 a1c6a512-1295-4272-9138-f99709370657

2008-12-26Latest work on the bmp on-load scaler:Andrew Mahone
Macros for calculating size needed for bitmap load and scaling, so that these can be compile-time constant when their inputs are. Reduce size of bayer dither by chopping all but first row of dither matrix, and replacing 2D lookup with 1D lookup and small calculation. Move some functions not related to actual bmp file loading out of bmp.c. A smaller brightness() for mono targets, and a higher-quality one for greyscale targets, both replacing the division by 10 with a shift. Port of the linear and area scalers to greyscale targets, this costs some binsize but produces better output even when dithered to 2bpp. Move duplicated row output code from inside vertical scalers to a separate row output function. Move some multiplies out of the line scaler, for a small speedup and code size reduction, as well as a small improvement in accuracy for the upscaling case. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19592 a1c6a512-1295-4272-9138-f99709370657
