Introduction

Overview

The XpdfAnalyze™ COM component 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), and 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.
