Purpose

Grimm is an Image Processor. It has been build up from many utilities I wrote since the end of 1992, when first AGA machines appear. It has now reached a high level of features, speed and quality. Grimm includes also some neat animation stuff and an MPEG encoder.

Some local screen shoots are provided to give you an idea of the features.

For more informations on Grimm , you may get the guide documentation.

Release

The last publicly available release can be downloaded right here.

Features

  • Color balance in RGB or YUV color space, including histogram functions, gamma, linear or spline based transfer curves for each channel
  • Color reduction in RGB or YUV color space, including various palette computation, dithering and HAM8 support
  • Convolution filters of 3x3, 5x5 or 7x7 matrix in RGB or YUV color space with channel selection
  • Palette editor and generator
  • Convert using flip, border, crop, magic wand, pixel aspect or resampling operations
  • Effect such as oil paint, mosaic, posterization or sphere
  • Distort with shear, rotate, bend, or spline based deformations
  • Filter with minimum, median or maximum filters
most of the above features may be used to build animations
  • Window or Screen based preview keeping pixel aspect integrity and using ordered dithering, grey scale, HAM8 or multicolor display methods
  • Turbo window drawing on OCS/ECS/AGA chipsets using a dynamic screen depth method
  • System friendly alien graphic cards are supported
  • Batch mode for easy color and file format conversions
  • Batch mode for easy images to animation conversion
