Parameters
| Name | Explanation |
|---|---|
| DeviceValue | The device context or the raster image data depending on the DeviceMode |
| ALeft, ATop | The x, y coordinates of the top left corner of the rectangle |
| ARight, ABottom | The x, y coordinates of the bottom right corner of the rectangle |
| ARect | The x, y coordinates of the rectangle |
| DeviceMode | If vikScreen, then the Rectangle will be drawn in pixel units. If vikPrinter, the Rectangle will be drawn in 0.1mm units. If vikMemoryHandle, the Rectangle will be drawn (in pixel units) to the image data |
Use either ALeft, ATop, ARight, ABottom or ARect.
Return Value
Returns True if successful. Returns False if unsuccessful.
Explanation
The Rectangle method draws a rectangle in the designated object (screen, printer, image data). The ALeft, ATop, ARight, and ABottom parameters define the coordinates specifying the rectangle. The outline of the rectangle is drawn from the value set in the PenStyle property and the rectangle is filled by the value set in the BrushStyle property. When drawing a rectangle, it is recommended that the PenWidth, PenMode, PenColor, BrushColor, Transparent, and BackColor properties also be set. The BackColor property is enabled when the Transparent property is False and the pen is solid or the brush is hatch pattern.
If the DeviceMode parameter is vikScreen or vikMemoryHandle then ALeft, ATop, ARight, ABottom parameters are in pixel units.
If the DeviceMode parameter is vikPrinter then ALeft, ATop, ARight, ABottom parameters are in 0.1mm units.
Differences between the ImageKit7/8/9/10
In VCL the constants contain a "v". In ActiveX, the constants
are: ikScreen, ikPrinter, ikMemoryHandle.
Methods that pass a TRect type have been added.
