ImageGlue 4.1 contains a number of fixes and enhancements. It is free to users of ImageGlue 4.0. Some of the more major changes and fixes are detailed below.

Version 4.1 now draws both Windows and Macintosh EPSF files if they contain embedded previews. To enable this, calls to DrawData now accept MacBinary data containing data and resource forks. Calls to DrawFile can now process files with multiple NTFS streams to allow the extraction of images from a Macintosh resource fork.

We now use the Intel JPEG Library 1.51. This eliminates a number of problems present in the previous version - the most common of which was a burnout when drawing some kinds of images containing large white areas. It also produces output images about 15% smaller.

The interpolation routine used for resizing and transforming images is now intelligently adjusted to allow for the particular type of transform. The effect of this is much higher quality images, produced faster without any code changes. If you require precise control over the interpolation routine you can achieve this using the 'interpolation', 'edgesmoothing' and 'ipl' parameters.

ImageGlue previously had problems drawing some kinds of Adobe Photoshop files if QuickTime was not installed. These problems have been resolved.

There are two new registry preferences. EPSFInfo determines if the EPSF information module is used or not - by default this is true. JPEGInfo determines if ImageGlue 4.1 custom JPEG information module is used or not - the default is false. The new custom JPEG information module is the only module to return correct DPI for CMYK JPEG images.

Registry preferences can be set by editing the registry using regedit. Both the EPSFInfo and JPEGInfo are DWORDs and should be entered under the key:


Please ensure that you take the proper precautions when editing the registry. If you do not know what these precautions are we suggest you do not change these settings.
