This method corrects a warped raster image.
Public Function Affine(x1 As Integer, y1 As Integer, x2 As Integer, y2 As Integer, x3 As Integer, y3 As Integer, x4 As Integer, y4 As Integer) As Boolean
public bool Affine(int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4);
Parameters
x1 to x4
The x coordinates of the four points
defining the area for Affine changes. (in pixels)
y1 to y4
The y coordinates of the four points
defining the area for Affine changes. (in pixels)
Return Value
Returns True if successful. Returns False if unsuccessful.
Explanation
The Affine method corrects a warped raster image. (Px1,Py1), (Px2,Py2), (Px3,Py3), (Px4,Py4) are the points of the (irregular) quadrangle that surrounds the area in the image to be corrected. The corrected area is squared and scaled to fit into a regular rectangle.
To execute the Affine method, set the image handle of the image in the SourceImage property. The Affine method supports 1, 4, 8, 16, 24, and 32 bit color images. If successful the resulting raster image data is set in the DestinationImage property.
