Diffuse 1.3

This filter will generate varying types of diffusion effects on your image.
Features:
-When digitizing images from any camera source, lens distortion (barrel / pincushion) becomes an unavoidable factor. By applying distortion correcting algorithms to the image, the amount of distortion can be minimized, and sometimes even corrected.
-Horiz, Vert: These sliders control the amount of distortion correction introduced in both the horizontal and vertical axes respectively.
-Lock Vert>Horiz: Locks the vertical slider to the horizontal for -proportional distortion correction.
-Color out-of-range: With pincushion distortion, pixels that are grabbed from outside the image boundaries are colored using the selected color.
-Presets: This drop-down menu defines what type of camera lens has been used and presets the appropriate distortion correction.
-NOTE: Custom allows user input while all other settings lock sliders to preset values.
Out-of-range color: This color specifies the out-of-range color.
-Fit: This pushbutton stands for fit-to-window. When this is selected, the image is scaled to compensate for distortion corrected size differences.
-Realtime: Applies all effects (in realtime) on mouse drag instead of on mouse release.
-R,G,B: These pushbuttons toggle which color channels to output. Sub-Sampling: Specifies what type of pixel sub-sampling to use. (Nearest Neighbor being fastest, Bicubic being best.)
