The Custom Shaders dialog can be used to create. Whether using a built-in or custom shader, a legend describing the color ramp and grid values is an important addition to the map view. Gaussian Blur - the Gaussian blur methods calculate the value to be displayed for each pixel based on the nearest 9 for 3x3 , 25 for 5x5 , or 49 for 7x7 pixels. Save the current HSV options in a text file. The Gradient Shader moderates the color with elevation between the low elevation and the high elevation.
