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.

1 // Load the specified image in memory
2 MarblecoreImaging.LoadFromFile("example-savehistogramtoimage-before.jpg");
3 
4 // Execute the operation
5 MarblecoreImaging.SaveHistogramToImage();
6 
7 // Save the modified image to the specified file
8 MarblecoreImaging.SaveToFile("example-savehistogramtoimage-after.jpg");
