ascompose - tool to compose image(s) and display/save it based on supplied XML input file.
ascompose -f file|-s string [-o file] [-t type] [-V]"
ascompose -f file|-s string [-o file] [-t type] [-V]"
ascompose -f file|-s string [-o file] [-t type] [-V] [-n]"
ascompose -f file|-s string [-o file] [-t type] [-V] [-r]"
ascompose [-h]
ascompose [-v]
ascompose reads supplied XML data, and manipulates image accordingly.
It could transform images from files of any supported file format,
draw gradients, render antialiased texturized text, perform
superimposition of arbitrary number of images, and save images into
files of any of supported output file formats.
At any point, the result of any operation could be assigned a name,
and later on referenced under this name.
At any point during the script processing, result of any operation
could be saved into a file of any supported file types.
Internal image format is 32bit ARGB with 8bit per channel.
Last image referenced, will be displayed in X window, unless -n option
is specified. If -r option is specified, then this image will be
displayed in root window of X display, effectively setting a background
for a desktop. If -o option is specified, this image will also be
saved into the file or requested type.
ascompose can be compiled to not reference X Window System, thus
allowing it to be used on web servers and any other place. It does not
even require X libraries in that case.
Supported file types for input are :
XPM - via internal code, or libXpm library.
JPEG - via libJpeg library.
PNG - via libPNG library.
XCF - via internal code. For now XCF support is not complete as it
does not merge layers.
PPM/PNM - via internal code.
BMP, ICO, CUR - via internal code.
GIF - via libungif library.
TIFF - via libtiff library (including alpha channel support).
see libAfterImage/ASImageFileTypes for more.
Supported file types for output :
XPM - via internal code, or libXpm library.
JPEG - via libJpeg library.
PNG - via libPNG library.
GIF - via libungif library.
TIFF - via libtiff library (including alpha channel support).
-h --help display help and exit.
-f --file file an XML file to use as input.
-s --string string an XML string to use as input.
-n --no-display don't display the last referenced image.
-r --root-window draw last referenced image image on root window.
-o --output file output last referenced image in to a file.
You should use -t to specify what file type to
use. Filenames are meaningless when it comes to
determining what file type to use.
-t --type type type of file to output to.
-v --version display version and exit.
-V --verbose increase verbosity. To increase verbosity level
use several of these, like: ascompose -V -V -V.
-D --debug maximum verbosity - show everything and
debug messages.
ascompose could be used both with and without X window system. It has
been tested on most UNIX flavors on both 32 and 64 bit architecture.
It has also been tested under CYGWIN environment on Windows 95/NT/2000
libAfterImage all the image manipulation routines.
libAfterBase Optionally. Misc data handling such as hash
tables and console io. Must be used when compiled
without X Window support.
libJPEG JPEG image format support.
libPNG PNG image format support.
libungif GIF image format support.
libTIFF TIFF image format support.

Here is the default script that gets executed by ascompose, if no
parameters are given :
static char* default_doc_str = "\
<composite op=hue>\
<composite op=add>\
<scale width=512 height=384><img src=rose512.jpg/></scale>\
<tile width=512 height=384><img src=back.xpm/></tile>\
</composite>\
<tile width=512 height=384><img src=fore.xpm/></tile>\
</composite>\
";
