sharpen()
Sharpen a true-colour image
Syntax
String = rb.GraphicImage.sharpen(percent)
Parameters
The 'sharpen' method takes 1 parameter:
| Name | Type/Value | Range/Length | Description | | percent | number | | Optional, default = 25
Percentage figure used to determine how aggressively to sharpen the image. Bigger numbers
indicate more agressive sharpen function. Values of greater than 100 are allowed.
|
Results
The 'sharpen' method returns String:
| Type/Value | Range/Length | Description |
| String |
|
Returns a reference to 'this' if the operation succeeds, otherwise throws an exception.
|
Remarks This method applies a sharpenning algorithm to the image. The single optional
percentage parameter specifies how hard the system should work at sharpenning
the image. Note that only true-colour images can be sharpenned. Invoking this
method on a palette image has no effect and is silently ignored. |
