the input image using a Laplace filter kernel.
Namespace:
Ranorex
Assembly:
Ranorex.Core (in Ranorex.Core.dll) Version: 12.7.4-git.38314c06
Syntaxpublic static Bitmap DetectEdgesLaplace(
Bitmap input

Public Shared Function DetectEdgesLaplace (
input As Bitmap
) As Bitmap
Parameters
- input
- Type: System.DrawingBitmap
An image.
Return Value
Type:
BitmapA grayscale image containing object edges.
Exceptions| Exception | Condition |

| ArgumentException | If the input image is not
a grayscale image and cannot
be converted to Format24bppRgb pixel format (i.e. if
it is no color image in a 32 bit format). |

By default the
LaplaceKernel5x5 is used as the filter kernel,
unless the image with or height is smaller than 5 pixels; in that case
the
LaplaceKernel3x3 is used instead.
