isCOBOL Evolve : User Interface : Controls Reference : TOOL-BAR : Properties : Background-Bitmap-Scale
Background-Bitmap-Scale
This property specifies what to do if the image dimensions don’t fit the Tool-Bar area.
The possible values for this property are:
0
The image is not altered. In this case, if the image is too large, it will be truncated, if it’s too small, it will be aligned to the top left corner of the Tool-Bar area.
1
The image is resized to fit completely the Tool-Bar area. The aspect ratio may be altered. This is also the default behavior when Background-Bitmap-Scale is not set.
2
The image is resized maintaining the aspect ratio. The resized image may not fit completely the Tool-Bar area.
The quality of the scaled image is controlled by the iscobol.bitmap_scale.best_quality (boolean) configuration property.
If the Tool-Bar is resized by a Layout-Manager and Background-Bitmap-Scale is set to "1" or "2", then the image is resized along with the window.
