# PixelMap Edit Control

The PixelMap tool edit control provides a graphic user interface to the PixelMapTool, which lets you define pixel value mappings between an input image and an output image:

See the topic Control Reference for a description of the buttons along the top of the edit control. The PixelMap tool edit control supports the following image buffers:

- The Current.InputImage provides the input image to the PixelMap tool.
- The Current.HistogramStats displays histogram data of the Current.InputImage.
- The Current.GraphicImage displays a histogram of the Current.InputImage and an overlay of the pixel mapping.
- The LastRun.InputImage displays the image that the tool last analyzed.

- The LastRun.OutputImage buffer displays the output image generated by the pixel mapping.
