Benefits and constraints on using PicClip images

In earlier releases of Dynamics, a separate image file was maintained and loaded for each button in a toolbar. By combining all images into a single PicClip image, the time required for loading these images has decreased substantially over loading them as separate images. Along with the name of the image file itself, Dynamics loads an X and Y offset, width, and height that identifies the portion of the PicClip containing a specific image. The performance improvement of using this mechanism is most noticeable the first time a container is launched and the images have not yet been loaded into the operating system cache.

Note: Even when not using PicClip images, the Dynamics image-loading process is optimized to minimize the number of searches using the relative path name of the image.

Dynamics only supports the use of PicClip images for the GUI environment.
