XpdfAnalyze^TM Library

The XpdfAnalyze library allows you to determine the object types and colors used on one or more pages in a PDF file. Object types are:

images
text strings
strokes (lines)
fills (filled polygons)

Object type information can be used to detect image-only, text-only, and image-and-text PDF files.

Color information includes color spaces (DeviceRGB, DeviceCMYK, Separation, etc.), as well as information on which process colors (CMYK) and/or custom colors (spot colors) are used.

XpdfAnalyze is easy to use:

PDFHandle pdf;
int n;

pdfLoadFile(&pdf, "MyFile.pdf");
pdfAnalyzePages(pdf, 1, 4); // analyze pages 1-4
n = pdfGetNumImages(pdf); // number of images on pages 1-4

Supported platforms:

Windows: DLL
Windows: COM component - usable from Visual Basic, Delphi, etc.
Linux: shared library
other platforms: portable C++ source code for the library is available
