Encapsulated PostScript (EPS)

PostScript Raster (Encapsulated PostScript). These files are used primarily on PostScript printers. These printers usually offer more variety of fonts and higher resolution than standard laser printers. EPS files will work on any PostScript compatible printer and any end-user application that supports placement of EPS files in its work space.

EPS support is part of the PDF support that is included with the LEADTOOLS PDF Pro, Pro Suite, Document, or Medical products.

The image that you read from an EPS file can be a PostScript image, a PostScript raster image, an embedded TIFF image, or an embedded WMF image. The image that you write to an EPS file is always a PostScript raster image.

These files can be forced to open thumbnails instead of the PostScript data by setting ELO_FORCE_EPS_THUMBNAIL flag in the LOADFILEOPTION structure.

For a PostScript image, you can read the following bits per pixel, using various DPI options: 1, 4, 8, 24. This requires the PDF filter.

For a PostScript raster image, you can read the following bits per pixel: 1, 8, 24.

For an embedded TIFF image, you can read the following bits per pixel: 1, 4, 8, 16, 24, 32.

For an embedded WMF file, you can read the following bits per pixel: 24.

You can write only an 8-bit PostScript raster image, which is grayscale.

It is possible to speed up the loading of large EPS files. For more information, refer to Using Filter Data to Speed up Loading Large Files.
