Shear method
Performs a shear transformation on the current image.
Syntax
Boolean Shear(nShearX As Number, nShearY As Number, bHighQuality As Boolean, nBackgroundColor As Number, nBackgroundOpacity As Number, nLeft As Number, nTop As Number, nWidth As Number, nHeight As Number)
Return value
Returns true if the function succeeded.
Parameters
Parameter | Type | Required | Description |
nShearX | Number | Yes | Specifies the horizontal shear of the image. |
nShearY | Number | Yes | Specifies the vertical shear of the image. |
bHighQuality | Boolean | No | Optional parameter which can be used to enable or disable the high quality mode. |
nBackgroundColor | Number | No | Optional parameter containing the background color. If no color is specified the current background color will be used. |
nBackgroundOpacity | Number | No | Optional parameter containing the background opacity. |
nLeft | Number | No | Optional parameter which can be used to specify a clipping rectangle. This parameter specifies the left coordinate of the rectangle. |
nTop | Number | No | Optional parameter which can be used to specify a clipping rectangle. This parameter specifies the top coordinate of the rectangle. |
nWidth | Number | No | Optional parameter which can be used to specify a clipping rectangle. This parameter specifies the width of the rectangle. |
nHeight | Number | No | Optional parameter which can be used to specify a clipping rectangle. This parameter specifies the height of the rectangle. |
Example
The example below shows the effect of this method and how to use it. You can slide the marker in the before/after picture to see the difference. If you take a look at the example code, assume there is a reference to the Marblecore Imaging object with the name 'MarblecoreImaging'. Transparent parts of the image are displayed using a checkerboard pattern.
