Using some simple filters for Image2D

With these examples, you can learn more about Image2D and how to make filters. The first one, "Threshold" is a good case to study when starting to create a new filter.

• Threshold an image | source
• Crop an image | source
• The filter that lets you apply a treatment at a pixel level | source
• A pixel-wise filter that uses pixel position to adapt its behaviour | source
• Use a math expression evaluator to blend an image and a mask | source
• Use a math expression evaluator to blend two images | source
• Create a pattern and blend it with an image using a math expression evaluator | source
• Save a Image2D to a *.pixp file | source
• Load a *.pixp file that contains an Image2D and display it | source
• Multiply an image by another | source
• Open a Tiff and display its pixel values in csv format | source
• Compute the dx and dy derivatives of an image | source
• Compute the gradient direction and magnitude of an image | source
• Compute all gradient info | source
• Compute elevation map from Mapbox TerrainRGB format | source
• Compute the 2D fourier transform and inverse transform on a syntetic image image | source
• Compute the 2D fourier transform and inverse transform on a single channel of a custom image image | source
• Extract single channels of an image or merge the channels of multiple images | source
• Apply a colormap on an image | source - see what kind of colormaps are available here
• Apply a colormap with clusters on an interpolated map | source - a bit slow due to the interpolation
