You can choose from the standalones that let you convert image file formats:
Convert image files to other formats including the format for creating memory-map textures with the imf_copy standalone.
Convert files between a variety of image file formats with the imgconv standalone.
Converting Image Files to Memory–Mapped Textures
The imf_copy standalone is used to convert image files to other formats including the format required to memory-map texture images into Softimage and the mental ray command line renderer.
For more information on memory mapping, see Using Memory-Mapped Textures [Texturing].
imf_copy supports the following file formats:
Converting between Many File Formats
The imgconv standalone converts files between a wide variety of image file formats. It also provides a set of image processing tools such as blur, contrast, and zoom.
imgconv automatically detects supported image file formats, so input files do not require an extension (such as .pic) to identify their format. To specify the format of the output file, you can use either an extension (such as .tif) or the -format option.
The imgconv standalone can convert to any file format for which there is a dynamic link library (DLL on Windows systems). The setup program installs these DLLs to <install directory>/Application/bin/sil. When you type imgconv, the usage message lists the supported file formats.
To run imgconv, you must set the environment variable SI_IMAGE_PATH to point to the <install directory>/Application/bin/sil directory.
imgconv <input file> <output file> [-height <height>] [-width <width>][-reduction <colormap size>] [-format <name>][-compression <none|rle|lzw|packbits>] [-description <string>] [-processor <name> ["<arguments>"]][-verbose]
Use a dash (-) to read from the standard input. imgconv automatically detects supported image file formats, so input files do not require an extension (such as .pic) to identify their format.
Use a dash (-) to write to the standard output. To specify the format of the output file, you can either use an extension (such as .tif) or the -format option.
