1. Idea

PicArt is a collection of standalone programs (like NETPBM), but additionally there is script-interface to each program: PicArtScript. It is loosely based on PostScript (stack-oriented) whereas also function-call with arguments approach can be chosen as illustrated in the graphic above. If you are familiar with Photoshop or GIMP, and you are experienced with programming languages, you will like PicArt and PicArtScript very much.

2. Disclaimer

This package comes WITHOUT ANY WARRANTY AND SUPPORT. We are very busy with other projects and do have really no additional time to provide support of any kind; I provide this source and this page as I know many people looking for packages like that, most of the c-source code is written straight forward without any consideration of optimization, speed or minimal use of memory, but solely by thoughts of simplicity and fast implementation.

Please consider to check out www.gimp.org, they actually put together the best drawing tool for UNIX called GIMP, which has also script interface (tcl and perl as well).

PicArt
3. Installation

Look at the Makefile and edit installation directory in case you don't want them in /usr/local/bin and /usr/local/lib/phtml/*

Create a link within the directory of PicArt called libjpeg pointing to the actual directory where libjpeg.a resides.

Run make and then make install to instal all pa* to /usr/local/bin directory.

4. The Glory Details

Consider to look at the overview of all programs and its script-interface.

PicArt
5. Fonts

There are two formats supported: PostScript Type1 (using t1lib), and TrueType (using freetype-lib), two public-domains libraries, the source-code is copyrighted. Check also TTFtoType1 to convert TTF to Type 1.

The most common asked question, where do I get the free fonts:

Please note, I cannot provide direct download as some fonts need to be registered with the authors/copyright holders.
