| Comments: |
This function creates and returns an image value by loading an image from a file. All images are rendered in 32-bit color. An indexed color must translate into an exact 32-bit match to cause transparency. Colors may have their own transparency data via alpha values. Using an image value can improve speed and reduce memory requirements over using a file name directly in a function or statement. EMF/WMF images will not display in the Anywhere Client. |
Example:
Image = MakeBitmap("C:\VTScada\VTS\Bitmaps\Arrows\Half rounded.wmf.png");
This will create an image value storing the image from the file "C:\VTScada\VTS\Bitmaps\Arrows\Half rounded.wmf.png".
