# Bitmap File Format Options

Photo>Graphics supports a large number of bitmap formats.

.JPG or .JPEG
  Joint Photographic Experts Group images
.PCD
  Kodak PhotoCD (requires OS/2 Multimedia support - default install with Warp)
.BMP
  OS/2 or Windows Bitmap
.GIF
  Graphics Interchange Format
.TIF
  Tagged Image File Format
.TGA
  Truevision Targa
.PCX
  PC Paintbrush format
.PPM/PGM/PBM
  Portable Bitmap Utilities format
.XBM
  X-Windows Bitmap
.PNG
  Portable Network Graphic
.EPS
  Encapsulated PostScript (save only)
.MPT/MAC
  MacPaint (load only)
.PS
  Postscript (save only)

You will note that you cannot load PostScript .PS files or Encapsulated PostScript .EPS files. They can only be used to save the output.

When saving bitmaps you have the option of specifying any number of options depending on the specific bitmap format chosen.

The bitmap format is chosen by the file extension on the saved file name (ie: SAMP.BMP saves as BITMAP, SAMP.TIF saves as TIFF).

If you supply no options the defaults are used. If any option is provided that is not relevant to that file format, it is ignored.

Options are separated by : (colons) or ; (semi-colons) or , (commas). Options with 1 or 0 values may simply entered without a value to activate.

Examples:

    call CwExportRendered 'c:\images\quux.jpg', 'progressive=1:quality=80'

    call CwExportRendered 'c:\images\quux2.jpg', 'progressive'

    call CwExportRendered 'c:\images\baz.gif, 'transparent:transparent color=(255,255,255)'

    call CwExportRendered 'c:\images\bobo.tiff', ''

In the above:
`progressive=1` and `progressive`
have the exact same meaning.

The options are:
