Top Previous Topic Next Topic  Print this topic

XF Ultrascale 2011 provides the xf:filter extension for applying filters to images in documents. This is an attribute that can be applied to raster images inserted via fo:external-graphic objects.

 

Possible values are:

 

convert-to-grayscale() - convert the image to grayscale
convert-to-cmyk() - convert the image to CMYK
convert-to-rgb() - convert the image to RGB

 

Example:

 

 

<fo:external-graphic src="C:\MyImage.jpg" xf:filter="convert-to-grayscale()" />
