Bitmap controls only.
For clipped bitmaps, this property specifies the location within the image (not within the control) to draw from.
offset = Get_Property(windowID, "IMAGEOFFSET")
oldoffset = Set_Property(windowID, "IMAGEOFFSET", newoffset)
Values passed in Set_Property and returned by both Get_Property and Set_Property have the format x:@fm:y where x and y are defined as:
| Parameter | Description |
|---|---|
| x | Number of pixels from the left edge of the image to draw from. |
| y | Number of pixels from the top edge of the image to draw from. |
Note: If the IMAGENUMBER property is set, IMAGEOFFSET specifies an offset within the image specified by IMAGENUMBER.
This property could be used, for example, to scroll a bitmap within a bitmap control. By repeatedly incrementing the x portion of the offset, the bitmap will scroll to the left.
IMAGECLIP, IMAGEORIGIN, IMAGENUMBER, IMAGECOUNT, BITMAP, and SIZE properties.
