DESCRIPTION:

This library provides an LVOOP-based interface to the powerful cross-platform ImageMagick image handling utility suite.

It supports all of the ImageMagick utilities and almost every command-line operator (over 200 of them) with support for custom user-specfied operators for the edge cases.

Several examples are included that demonstrate basic text & image creation, composition, and conversion in and out of LabVIEW (including VI icon creation).

GETTING STARTED:

The first thing you need to know about ImageMagick is that it has a pretty steep learning curve. Complicated things are complicated, and easy things are sometimes complicated, too. The Example VIs provided with the project are intended to give you a basic start on how to use the library, but you should expect to consult an ImageMagick Examples Page frequently.

COMPATIBILITY:

The library is written for cross-platform usage, but is currently limited to compatibility with Windows because I don't have any non-Windows LabVIEW machines to write the platform-specific code on. If you can help out with compatibility for other platforms, please contact me. I would LOVE to hear from you.

REQUIREMENTS:

A working Windows ImageMagick installation. Tested with ImageMagick v6.3.4-Q16. Almost certainly works with later versions, and probably with earlier versions back to at least v5.4.8. (Personal testimonials on this are welcome.)

REQUIRED minimum OpenG Packages:

oglib-error-2.3.2

oglib-lvdata-2.7.2

RECOMMENDED OpenG Packages: (used in examples, but not in the core functions)

oglib-file-2.8.1

oglib-array-2.5.1

KNOWN ISSUES:

Currently applications built against this library throw a litany of execution errors when run in the RTE. If you need to build these libraries into an application, please contact me and I will try to help you.

Functions for a few of the built-in pattern generators are not completely implemented. You can access them using a custom raw operator argument.

CHANGE LOG:

1.0.1: Fixed an incompatibility with ImageMagick 6.3.4 when using certain operators.

Added a better error message when ImageMagick can't be located under Windows.

1.0.0: Initial release (06/18/2007)
