| Top | The vertical distance from the top of the actual image to the top of that portion of the image currently being displayed. |
| Right | The horizontal distance from the left side of the actual image to the right side of that portion of the image currently being displayed. |
| Bottom | The vertical distance from the top of the actual image to the top of that portion of the image currently being displayed. |
| ScaleWidth | The horizontal scale between the displayed portion of the image and the actual image. |
| ScaleHeight | The vertical scale between the original image and the displayed image. |
| x, y | The coordinates on the image where the mouse button was pressed. |
The values are in pixels.
Explanation
The MouseDownImage event is generated when the mouse cursor is inside the image and the mouse button has been pressed. This event is enabled when a valid image handle is set in the ImageHandle property or the Layer(LayerNo).ImageHandle property.
Note: The MouseDownImage event is generated before the standard MouseDown event.
When multiple keys are pressed the result calculated as a "Bitwise OR operation", meaning, for example, that if both the Ctrl key and the Alt key were pressed, the value of shift would be 6.
The OriginX parameter and the OriginY parameter depend on the values set in the BorderVisible, Appearance, and Grad properties.
If using Visual Basic.NET or Visual C#.NET, please refer to the section Regarding VB.NET and C#.NET.
Note for Visual Basic:
In order to use the Left($) function and Right($) function within this event, please change the names of the Left and Right parameters of this event.
For Example:
Private Sub ImageKit1_MouseDownImage(ByVal
Button As Integer, ByVal Shift As Integer, ByVal OriginX As Long,
ByVal OriginY As Long, ByVal Left_ As Long,
ByVal Top As Long, ByVal Right_ As Long, ByVal
Bottom As Long, ByVal ScaleWidth As Double, ByVal ScaleHeight As
Double, ByVal x As Long, ByVal y As Long)
