I've set up an object script which does a whole pile of funcdef to interface a fair bit of ImageMagick and MagickWand to Reginald. This then allows me to save the image produced by rxprint as a PNG or GIF, for example, which are only 3kb files instead of the 762kb file produced by a BMP.

I do this by sending the rxprint bitmap to the clipboard and then using these calls to MagickWand:
magickwandgenesis()
m_wand = newmagickwand()
magickreadimage(m_wand,"clipboard:")
magickwriteimage(m_wand,fn)
destroymagickwand(m_wand)
magickwandterminus()
where "fn" is the filename returned by the guifile statement in rxprint and can be any file format understood by ImageMagick (and that's a lot of formats - gif,tif,png,jpg,bmp, and many more). With a few extra function calls you can also do things like set the JPG compression, resize the image, add a frame, write more text on the image, and so on.

In order to use it you must, of course, have ImageMagick installed. The windows self extracting installer is a 6.7MB download which expands to about 20MB on disk. Once installed you only need to point my object file at your installation and off you go!

See: http://imagemagick.org/script/binary-releases.php#windows

For this kind of application the Q8 DLL version is best.

If there's any interest, I'll package up the current version of my object interface and some demo scripts.
