FAQ
SIG to PGM Conversion
What are SIG files?
SIG is a raster image format used to store a handwritten signature as a picture, so that it can be placed on documents, forms, and letters in place of a pen signature. A file of this type holds a single bitmap, usually a scan, a photograph, or a capture from a signature pad, and carries no layers, no text, and no vector strokes. Signature images are normally small, often a few hundred pixels wide, with a white or transparent background and dark ink. The data is compressed JPEG, and some systems that produce the files, typically document management and e-signature software, store it in a modified byte order. For that reason, a generic image viewer may not recognize a .sig file until its contents are converted.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
