Leadtools.ImageProcessing Namespace : UserFilterCommand Class

Remarks

  • With this command you can create a user-defined filter and apply it to the image. The filter has a rectangular form (matrix) where the values are user-defined. It allows the creation of simple customized filters, where each value in matrix is multiplied by the corresponding pixel, and then the specified operation is performed on the results.
  • When the filter is applied to pixels from the edge and you choose the sum operation, the edge rows and columns are duplicated. For example, if the pixel (-1, 5) is needed, the pixel (0, 5) is used instead.
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
