Some useful features are not included in the current version of iplab, but there is another open source application that has accessories that you may want to integrate with IPlab.
Main features:
- Color filters (grayscale, sepia, invert, rotate, channel extraction, channel replacing , channel filtering, color filtering, Euclidean color filtering);

A small tool to visualise different graphic processes. It was written as a final year project in Visual C++. It loads in pictures and allows the user to apply different filters by choosing the coefficients as well as the matrix size.

BIMP is a small and simple batch processor for image files, that allows you to perform various functions on multiple images.
It can be used to create thumbnail images from your pictures, add a prefix/postfix, replace spaces in the file name with underscores, flip or rotate images and also apply anti-aliasing and emboss effects.
BIMP Batch Image Processor is a software that allows you create thumbnail images.
The thumbnail resizing allows you to force a specified width or height and keep the proportions, or define fixed image dimensions.
In addition, the program can also convert the file format to GIF, JPG, TIFF, PNG, BMP, MIFF or TGA. All of the actions can be performed individually, or combined.
Enhancements:
- Fixed overflow problem (I think)
- File rotate setting now resets when it should
- Error reporting now includes all settings
- German translation (Thanks Jochen)

Image Robot 1.2 offers you a powerful one-stop source for batch image processing. You can easily convert a variety of image file formats, resize images and create and apply an optimized palette to any number of images, all in a batch process mode. No programming is necessary... simply select the image files and the batch process commands you would like to use and Jasc Image Robot does the rest in a fraction of the time it would take to edit each file separately.
