Engauge digitizing software converts an image file showing a graph or map,
into numbers. The image file can come from a scanner, digital camera or
screenshot. The numbers can be read on the screen, and written or copied
to a spreadsheet. Engauge Digitizer compensates for rotation, scaling
and skew (also known as shearing) in graphs. Engauge recognizes BMP, CUR,
DDS, GIF, ICNS, ICO, JP2, JPG, MNG, PBM, PDF, PGM, PNG, PPM, SVG, SVGZ,
TGA, TIFF, WBMP, WEBP, XBM and XPM image files.
