Other programming topics are related to web and cloud development and system and hardware programming.

This first video Micro Tutorial in my Xpdf series introduces and describes Xpdf, a library containing nine command line utilities that perform various functions on PDF files. This video shows where the library is located and how to download it, discusses its licensing provisions, and provides a brief description of each of the nine modules.

Since all the utilities offer a command line interface, they are suitable for use in batch files, programs, and scripts — any place where a command line call can be made. For example, I have written many programs in the AutoHotkey scripting language that call the various Xpdf utilities via the AutoHotkey RunWait command.

This first video sets the stage for subsequent Micro Tutorials in the Xpdf series. You'll see that this video says it is "Part 1 of 3" (the second says, "Part 2 of 3"; the third, "Part 3 of 3"). However, after publishing the first three tutorials, I decided to do one for each of the other tools, as well as one for the Xpdf configuration file (xpdfrc), which is common to all nine utilities. Here are links to the other 10 five-minute video Micro Tutorials at Experts Exchange:

Xpdf - PDFimages - Command Line Utility to Extract Images from PDF Files
Xpdf - PDFtoText - Command Line Utility to Convert PDF Files to Plain Text Files
Xpdf - PDFinfo - Command Line Utility to Retrieve Page Count and Other Information from PDF Files
Xpdf - PDFdetach - Command Line Utility to Detach Attachments from PDF Files
