DESCRIPTION

Vxthm Generates thumbnail images for use with a web system. It accepts many different image formats including image sequences. If provided with file it computes the thumbnail for that file only. If provided with a directory it computes thumbnails for all the recognized images in that directory. In this case the thumbnail for <file> is <file>.thm

CONSTRAINTS

OPTIONS

if=<fname>

input file or directory

	-p		Generates an image from a pipe (probably broken)
	-e		Create thumbnails only for files with known extensions. (this context is files that are handled in the web by jiview).
	-v		selects the verbose mode and prints some information about its action.
	-tiff
	-tif		creat thumbnails for tiff images. Simple convesion, not for current jiview, may not work with some tiff images. Currently, .tif and .tiff are not recognized by -e.

ex=<extension>

The standard filename extesnion created by vxthm is "thm" for non-web use (read windows) you way want to use jpg or jpeg. WARNING when you run vxthm in a directory it first removes all files with the thumbnail extension so only give an extension that is not alredy used by an image file in that directory. Hint, if there are .jpeg files use jpg and if there are jpg files use .jpeg.
