Warp images arbitrarily in C#, Part 2

Posted on August 19, 2016 by Rod Stephens

The post Warp images arbitrarily in C#, Part 1 explains how to warp images, but it omits the method that maps an output pixel (x1, y1) back to an input pixel (x0, y0) in the original image. This post describes … Continue reading →

Warp images arbitrarily in C#, Part 1

Posted on August 18, 2016 by Rod Stephens

This is an extension of the example Use image filters to perform edge detection, smoothing, embossing, and more in C# that adds new features that warp images in arbitrary ways. The idea is to use two functions F(x, y) and … Continue reading →

Apply a filter to make a color embossed image in C#

Posted on September 2, 2014 by Rod Stephens

This example extends the earlier one Pixellate an image and create other effects in C# by adding a new filter that makes a color embossed image without removing most of the color information. The filter’s kernel is: 1 1 -1 … Continue reading →

Pixellate an image and create other effects in C#

Posted on September 2, 2014 by Rod Stephens

This example extends the previous example Use image filters to perform edge detection, smoothing, embossing, and more in C# by adding the ability to pixellate an image. It also adds the ability to load and save files, and a few … Continue reading →

Use image filters to perform edge detection, smoothing, embossing, and more in C#

Posted on September 2, 2014 by Rod Stephens

Image filters let you perform operations on the pixel in an image. This is a fairly large example so you may want to spend some time walking through the code. In one kind of image filter, you have an array … Continue reading →
