Variable: preview-gs-image-type-alist

preview-gs-image-type-alist is a customizable variable defined in preview.el.

Value

 (jpeg jpeg "-sDEVICE=jpeg") (pnm pbm "-sDEVICE=pnmraw")
 (tiff tiff "-sDEVICE=tiff12nc"))

Documentation

Alist of image types and corresponding Ghostscript options.

The dvi* and postscript (don't use) entries really specify a fallback device when images can't be processed by the requested method, like when PDFTeX was used.

This variable was added, or its default value changed, in auctex version 14.2.0.
