Image Controls (Magic xpa 2.x)
In Image controls, you can insert images by specifying a file name, by mapping a variable that is an image, or by defining an expression that evaluates to yield an image.
The image can be used in two modes:
-
Static control – The control is static when the Data property is left empty and a file name and path are specified in the Default image file property.
-
Dynamic control – The control is dynamic when a variable or expression is set in the Data property, containing a file name value.

-
When using animated gif files, the animation will only be seen if the Image Style is set to Copied. Since version: 1.5
-
When the control size on the form is different than the image size, the image may look distorted since it has been stretched. In order to have a more accurate control size, it is recommended to use a high value in the horizontal and vertical factors and then use the Fit Size option in the Command palette.
-
The following images types are supported for the Rich Client Image control: BMP, GIF, JPEG, and PNG.
-
Once an image is loaded to the Image control, it will remain in the memory cache, so an update will only be seen after restarting the task.
