asimagexml(1)	   libAfterImage image manipulation library	 asimagexml(1)

NAME
       asimagexml -  XML schema to be used for scripting image manipulation by
       AfterStep and ascompose libAfterImage/asimagexml

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

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, 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.

TAGS
       Here is the list and description of possible XML tags to use in the
       script :
	   img	     - load image from the file.
	   recall    - recall previously loaded/generated image by its name.
	   text	     - render text string into new image.
	   save	     - save an image into the file.
	   bevel     - draw solid bevel frame around the image.
	   gradient  - render multipoint gradient.
	   mirror    - create mirror copy of an image.
	   blur	     - perform gaussian blur on an image.
	   rotate    - rotate/flip image in 90 degree increments.
	   scale     - scale an image to arbitrary size.
	   slice     - enlarge image to arbitrary size leaving corners unchanged.
	   crop	     - crop an image to arbitrary size.
	   tile	     - tile an image to arbitrary size.
	   hsv	     - adjust Hue, Saturation and Value of an image.
	   pad	     - pad image with solid color from either or all sides.
	   solid     - generate new image of requested size, filled with solid
		    color.
	   composite - superimpose arbitrary number of images using one of 15
		    available methods.
	if	  - conditional processing based on value of the variables
	set	  - sets value of the variable
	printf	  - formated printing of the value of the variable

       Each tag generates new image as the result of the transformation -
       existing images are never modified and could be reused as many times
       as needed. See below for description of each tag.

       Whenever numerical values are involved, the basic math ops (add,
       subtract, multiply, divide), unary minus, and parentheses are
       supported.

       Operator precedence is NOT supported.  Percentages are allowed, and
       apply to either width or height of the appropriate image (usually
       the refid image).

       Also, variables of the form $image.width and $image.height are
       supported.  $image.width is the width of the image with refid "image",
       and $image.height is the height of the same image.  The special
       $xroot.width and $xroot.height values are defined by the the X root
       window, if there is one.	 This allows images to be scaled to the
       desktop size: <scale width="$xroot.width" height="$xroot.height">.

       Each tag is only allowed to return ONE image.

NAMEtext

       This   tag applies to the first image contained within the tag. Any

       further
	      images will be discarded.

       If     you  want to keep image proportions while scaling - use "propor‐

NAMEslice
       - slice image to arbitrary size leaving corners unchanged

SYNOPSIS
       <slice id="new_id" ref_id="other_imag" width="pixels" height="pixels"
	      x_start="slice_x_start" x_end="slice_x_end"
		 y_start="slice_y_start" y_end="slice_y_end"
		 scale="0|1">

ATTRIBUTES
       id     Optional. Image will be given this name for future reference.

       refid  Optional.	 An  image  ID defined with the "id" parameter for any
	      previously created image. If set,	 percentages  in  "width"  and
	      "height"	will be derived from the width and height of the refid
	      image.

       width  Required. The image will be scaled to this width.

       height Required. The image will be scaled to this height.

       x_start
	      Optional. Position at which vertical image slicing begins.  Cor‐
	      responds to the right side of the left corners.

       x_end  Optional.	 Position  at which vertical image slicing end. Corre‐
	      sponds to the left side of the right corners.

       y_start
	      Optional. Position at which  horisontal  image  slicing  begins.
	      Corresponds to the bottom side of the top corners.

       y_end  Optional. Position at which horisontal image slicing end. Corre‐
	      sponds to the top side of the bottom corners.

       scale  Optional. If set to 1 will cause middle portion of the image  to
	      be scaled instead of tiled.

NOTES
       This tag applies to the first image contained within the tag.  Any
       further images will be discarded.
       Contents of the image between x_start and x_end will be tiled
       horizontally. Contents of the image between y_start and y_end will be
       tiled vertically. This is usefull to get background images to fit the
       size of the text or a widget, while preserving its borders undistorted,
       which is the usuall result of simple scaling.
       If you want to keep image proportions while resizing-use "proportional"
       instead of specific size for particular dimention.
