Digital images can usually be divided into two distinct categories. They are either bitmap files or vector graphics. If you work in prepress, you need a good understanding of the advantages and disadvantages of both types of data.

Raster Images vs. Vector Graphics

Computer graphics can be created as either raster or vector images. Raster graphics are bitmaps. A bitmap is a grid of individual pixels that collectively compose an image. Raster graphics render images as a collection of countless tiny squares. Each square, or pixel, is coded in a specific hue or shade.

Difference Between Bitmap and Vector (With Table)

A bitmap also called "raster" graphic is created from rows of different colored pixels that together form an image. In their simplest form, bitmaps have only two colors, with each pixel being either black or white. With increasing complexity, an image can include more colors; photograph-quality images may have millions. The image displayed on a computer monitor is also a bitmap, as are the outputs of printers, scanners, and similar devices. They are created using paint programs like Adobe Photoshop. Vector also known as "object-oriented" graphics are constructed using mathematical formulas describing shapes, colors, and placement. Rather than a grid of pixels, a vector graphic consists of shapes, curves, lines, and text which together make a picture.

In other words, I want to generate a PDF with the exact same un-rasterized text but with each vector image replaced with a rasterized version. However, while raster images seem to make it through the conversion process fine, vector images get horribly mangled. It would be great if I could easily convert a PDF so that all of its vector images were rasterized. I am interested in any possible solutions, but a Linux- or Windows-based one would be preferable.

Bitmap versus vector graphics

This is important since the two file types are converted differently. Vector PDF files are best transformed through data extraction. This is accurate and precise and involves minimal manual clean-up. Raster PDF files are traced since there is no data to extract. This is an approximation and requires operator involvement as well as manual clean-up.
