Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

C code generation utility for GdkPixbuf images

SYNOPSIS
|
|
--------
|
|
| **gdk-pixbuf-csource** [OPTIONS...] <IMAGE>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
``gdk-pixbuf-csource`` is a small utility that generates C code containing
|
|
images, useful for compiling images directly into programs.
|
|
|
|
``gdk-pixbuf-csource`` either takes as input one image file name to generate
|
|
code for, or, using the ``--build-list`` option, a list of (``name``, ``image``)
|
|
pairs to generate code for a list of images into named variables.
|
|
|
|
This tool is mostly meant to be used for backward compatibility. Newly written
|
|
applications and libraries should use GResource to embed image assets in their
|
|
binary.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
``--stream``
|
|
|
|
Generate pixbuf data stream: a single string containing a serialized
|
|
``GdkPixdata`` structure in network byte order.
|
|
|
|
``--struct``
|
|
|
|
Generate ``GdkPixdata`` structure; your code needs the ``GdkPixdata``
|
|
structure definition from ``gdk-pixdata.h``.
|
|
|
|
``--macros``
|
|
|
|
Generate ``*_ROWSTRIDE``, ``*_WIDTH``, ``*_HEIGHT``, ``*_BYTES_PER_PIXEL``
|
|
and ``*_RLE_PIXEL_DATA`` or ``*_PIXEL_DATA`` macro definitions for the
|
|
image.
|
|
|
|
``--rle``
|
|
|
|
Enables run-length encoding for the generated pixel data (default).
|
|
|
|
``--raw``
|
|
|
|
Disables run-length encoding for the generated pixel data.
|
|
|
|
``--extern``
|
|
|
|
Generate extern symbols.
|
|
|
|
``--static``
|
|
|
|
Generate static symbols (default).
|
|
|
|
``--decoder``
|
|
|
|
Provide a ``*_RUN_LENGTH_DECODE(image_buf, rle_data, size, bpp)`` macro
|
|
definition to decode run-length encoded image data.
|
|
|
|
``--name=identifier``
|
|
|
|
Specifies the identifier name (prefix) for the generated variables or
|
|
macros (useful only if ``--build-list`` was not specified).
|
|
|
|
``--build-list``
|
|
|
|
Enables (``name``, ``image``) pair parsing mode.
|
|
|
|
``-h, --help``
|
|
|
|
Prints a brief help and exit.
|
|
|
|
``-v, --version``
|
|
|
|
Prints the tool version and exit.
|
|
|
|
``--g-fatal-warnings``
|
|
|
|
Makes warnings fatal, and causes the program to abort.
|
|
|
|

BUGS
|
|
----
|
|
|
|
The runlength encoder gets out of sync with the pixel boundaries, since
|
|
it includes the rowstride padding in the encoded stream. Furthermore, it
|
|
generates pixbufs with suboptimal rowstride in some cases.
