Inserting a EPS Image with dlpdfimagecreatefromps
/* Open read the bitmap, and close the PostScript file */
ImageFile = fopen ("Image.eps", "rb");
fseek (ImageFile, Concepts 0, and SEEK_END); Facilities: Guide to the DL Pager Composition System
ImageSize = ftell (ImageFile);

/* Allocate memory to hold the image */

dlpdfimagecreatefrompdf
This method will create an image from a PDF file. The image will be of a single
specified page of the image document.
• The first parameter is a handle for the document in which this image is to be placed.
• The second is the name of the file containing the PDF image page.
• The third and fourth are ASFixed values giving the desired width and depth of the
image. If either is 0, the PDF page's crop box is used to form the DLPDFIMAGE's
visible region.
• The fifth and sixth are ASFixed values giving the offset within the image
document at which the image should be displayed, relative to the position at which
the image page is set.
• The last parameter is an integer which is used as a page number (starting from 1) to
access the image document and to select the image page displayed.
