This method rotates a raster image.
Parameters
angle
Angle of rotation (-35999 to 35999, in 1/100
degree units)
xTurn
Reverses image along the x axis (False: no
reversal, True: reversal)
yTurn
Reverses image along the y axis (False: no
reversal, True: reversal)
mode
Sets whether on not linear interpolation is used
(False: does not interpolate, True: interpolates)
Interpolation is enabled for 8 bit grayscale, 16,
24, and 32 bit images only
red
The red component of the background color (from 0
to 255)
green
The green component of the background color (from
0 to 255)
blue
The blue component of the background color (from
0 to 255)
clip
Sets whether or not the image is clipped (False:
no clipping, True: clipping)
Return Value
Returns True if successful. Returns False if unsuccessful.
Explanation
The Rotation method rotates a raster image. If the Angle parameter value is positive, the image is rotated counterclockwise, if the Angle parameter value is negative, the image is rotated clockwise. When the Clip parameter is True and the rotated image is larger than the original, the excess areas are cut.
To execute the Rotation method, set the image handle of the image in the Image property or the Layer(LayerNumber).Image property. The Rotation method supports 1, 4, 8, 16, 24, and 32 bit images. It is possible to rotate a mask image at the same time that the image is rotated. If this is the case, set the image handle of the mask image to be processed in the SourceMask property.
If successful the resulting raster image data is set in the LayerNo property (the ImageHandle property or the Layer(LayerNo).ImageHandle property. If a mask image is used, the mask image should be set in the SourceMask property. The resulting mask image will be set in the DesinationMask property.
