SYNOPSIS
pgmtosbig [pgmfile]
DESCRIPTION
pgmtosbig converts a PGM (Portable Graymap) image into SBIG Type 3 format, the uncompressed image format used by Santa Barbara Instrument Group (SBIG) astronomical CCD cameras.The output is uncompressed image data with a header identifying the source as an ST-6 camera, along with camera type, image dimensions, and saturation level metadata.Note that SBIG Type 3 is distinct from the older SBIG ST-4 format handled by [pgmtost4](/man/pgmtost4)(1). The reverse conversion is performed by [sbigtopgm](/man/sbigtopgm)(1).The program accepts input from a file argument or standard input, and writes to standard output. It has no tool-specific options beyond the common Netpbm options. Part of the Netpbm toolkit (since Netpbm 10.70).
