type
TVIkOutPutDeviceMode = (vikScreen,
vikPrinter, vikMemoryHandle);
Parameters
| Name | Explanation |
|---|---|
| DeviceValue | The device context or the raster image data depending on the DeviceMode |
| ALeft, ATop | x and y coordinates of the starting point of the line |
| ARight, ABottom | x and y coordinates of the ending point of the line |
| ARect | The x, y coordinates of the rectangle bounding the starting point and ending point of the line |
| DeviceMode | If vikScreen, then the line will be drawn in pixel units. If vikPrinter, the line will be drawn in 0.1mm units. If vikMemoryHandle, the line 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 Line method draws a line in the designated object (the screen, printer, or image memory handle). The line is drawn from the top, left coordinates (starting point) to the bottom right coordinates (ending point) or from the top left corner to the bottom right corner of ARect. Note: The ending point is not included in the line. This method can draw in the following designated objects: screen, printer, and memory handle. The line is drawn from the value set in the PenStyle property. This property must be set. When drawing a line, it is recommended that the PenWidth , PenMode, PenColor, Transparent, and BackColor properties also be set. The BackColor property is enabled when the Transparent property is False and the pen is solid.
If the DeviceMode parameter is vikScreen or vikMemoryHandle then the left, top, right, bottom parameters will be in pixel units.
If the DeviceMode parameter is vikPrinter then the left, top, right, bottom parameters will be 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.
