Creating a bitmap image from a PDF is normally done in RGB, but when that PDF contains overprinting or depends on CMYK blending, you need something more. This article tells you how.
Our second image extraction article, this time using a java webapp.
The first of two articles demonstrating how to extract bitmap images from PDFs using the BFO PDF Library API.
Europe's largest semiconductor chip manufacturer celebrate tenth anniversary deploying the BFO PDF Library Extended.
There are many situations where a PDF has to be "rasterized" - the contents of each page turned into a bitmap image - such as when a PDF is being converted to PDF/A and the page contents cannot be repaired. This article shows how to do it efficiently.
When working with Java APIs that use native code you can hit an OutOfMemory in the PermGen space due to weaknesses in Java's garbage collectors. Here's an ugly little hack that might help.
Sometimes when you convert a PDF to TIFF, you're left with a lot of whitespace around the content of the page. This article shows an easy way to remove it.
We're asked some questions more than others at BFO, and one of the most common concerns conversion of a PDF to a bitmap image format - typically TIFF, but sometimes JPEG or another format. This process is called "rasterization" and while it's very easy to do with the "extended plus viewer" version of our PDF Library, it's worth going over in more detail.
