NAME

ascompose - provides access to libAfterImage functionality, using scripts written in custom XML dialectlibAfterImage/ascompose

NAMEascompose

is a tool to compose image(s) and display/save it based on supplied XML input file.

SYNOPSIS

ascompose -f file|-s string [-o file] [-t type] [-V]ascompose -i include_file [-i more_include_file ... ]             -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 [-c compression_level]]              [-V] [-r]ascompose [-h]ascompose [-v]

DESCRIPTION

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, performsuperimposition of arbitrary number of images, and save images intofiles 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 operationcould 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 optionis specified. If -r option is specified, then this image will bedisplayed in root window of X display, effectively setting a backgroundfor a desktop. If -o option is specified, this image will also besaved into the file or requested type.ascompose can be compiled to not reference X Window System, thusallowing it to be used on web servers and any other place. It does noteven 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).

OPTIONS

   -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.   -c --compress level compression level.   -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.   -i --include file  include file as input prior to processing main                          file.

PORTABILITY

ascompose could be used both with and without X window system. It hasbeen 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

USES

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.
