Reduce Resolution

The aim of this plugin is to be able to reduce the file size without having to crop the images and so a faster processing time in other plugins. This is in particular helpful if a large image is made with the plugin Stitching HIS Images, because the images that it is made from can functions as detailed views. This means that there is no data lost.

Theory

The algorithm takes a x by y area and averages into one points, hereby reducing the resolution. This area can be a rectangle or a square. Before this can be done there is one step to do first and that is to crop the images in such a way that the images can be filled with rectangles without leftover areas. The pixels are removed from the top and right part of the images and never more than x pixels in width and y in height.

Using the plugin

1. Load the plugin by selecting an images.
2. Fill in the filename and the x and y parameters.
3. Run the algorithm and the output is saved and can be visualised with the according display plugin.
