The Advanced tab allows you control over color profiles and some
other miscellaneous features.
Color Conversion using ICC profiles is enabled by default. If
you wish to disable it you can do so using the 'Use Color Profiles'
control. This will speed up operations requiring color conversion
at some significant cost in terms of image quality.
When a color conversion is performed ImageGlue will need some
default profiles. It will always need an sRGB or RGB destination
profile and it may need a CMYK or other profile if the image does
not contain one. ImageGlue contains default profiles but you can
specify your own replacements by entering a path to a 'Color
Profile Directory'. Remember to ensure that the IIS user (IUSR) has
read access to this directory.
ImageGlue uses interpolated transforms for high quality image
resizing, rotation and transforms. If you have a very high end
video card it may produce equal quality results without placing a
load on the CPU. If this is the case you can disable interpolated
If your code does not handle errors properly then they may get
missed in production output or stress testing. By checking the
'Record VBScript Errors' checkbox any errors will also be directed
to the Windows NT Application event log as warnings. The log can
then be checked periodically to ensure the integrity of your web
Impersonation is accessed using the Impersonation Parameters.
Although convenient the use of Impersonation may be a security risk
and so you must manually enable it if you want to use it.
The Maximum Image Dimensions allows you to limit the size of
images accepted by ImageGlue. The load placed on a server is often
related to the width and height of the image to be drawn. This may
be equally true whether the image is drawn on a small canvas or on
a large one. You can manually limit the width and height of images
using the Graphic object but IGSettings provides an easy way of
ensuring that images larger than a predefined size are
