rockbox/apps/recorder/bmp.h, branch master

Support GIMP bmp files.

Change-Id: I7380ceeaf696b67e1641d24e7b932e3d74770932

Support for transparency in 32bit bitmaps on color targets.

2011-11-08T21:36:49+00:00

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.

Inline output_row_8_native when building bmp.c in core without HAVE_JPEG or HAVE_BMP_SCALING.

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20886 a1c6a512-1295-4272-9138-f99709370657

Split 8-bit-to-native conversion in bmp.c into a function, add support for plugging unscaled output in BMP and JPEG loaders, use output_row_8_native in JPEG decoder when possible.

cleanup for core-file-in-pluginlib compilation:

2009-01-08T02:49:23+00:00

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

viewer using greylib.

Latest work on the bmp on-load scaler:

2008-12-26T07:03:22+00:00

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.
