If you have more than one text string to render, you should get a substantial speed up by collecting all the strings into a drawable and only rendering them once rather than individually. Use DrawablePushGraphicContext() and DrawablePopGraphicContext() to separate the text attributes if need be.

We run the valgrind memory debugger on ImageMagick under Linux to ensure there is no heap corruption, however, ImageMagickObject/MagickCMD are contributed projects so its possible they have bugs. When we run MagickCMD convert logo: logo.gif no faults are evident. We'll give the code a once-over look...

Implementing the font caching in ImageMagick will be quite time consuming to do it properly. Instead consider sending us a stripped down code/script of what you are doing and we will run a profile to see if we can identify opportunities for speed-ups. If we reproduce the slow-down you are getting, p...

Type identify -list format Chances are JPEG is not listed or its listed with a mode of --- which means it read or write it.

You can always set environment variables without administrator privileges. We assume you mean you can't set Window registry entries. Grab the ImageMagick Windows source and build. The default is a non-installed build which does not require the Windows registry. You simply set the MAGICK_HOME environ...

We'd certainly like to hear from you if you come up with a solution to the speed problem. We designed ImageMagick to be general purpose so we had to trade-off certain optimizations to ensure support for the greatest number of image formats, colorspaces, storage classes, etc.

Is lcms listed as a library for the LIBS tag? The LCMS delegate library is required to apply color profiles to an image. You could use the option -colorspace CMYK but the color conversion can not match that of a profile conversion.

When you install ImageMagick there is a panel that gives you an option to include the ImageMagick header files. The header files are not installed unless the option is checked.
