IFSgr is a command line two-dimensional linear IFS (Iterated Function System) grayscale renderer.

IFSgr uses Fractint's IFS file format, and features automatic fractal scaling and gray level adjustment and consistent image look independent of size or the numbers of iterations.

It can also convert Fractint files to Gimp IFS Compose files and back.

Here are some key features of "IFSgr":
Reads and writes Fractint 2D IFS files, allowing to select particular fractals from them with easy :: notation.
Reads FDESIGN TRN files.
Reads and writes Gimp IFS Compose (IFSC) files.
Renders high-quality grayscale images (see the IFS gallery), automatically scaling the fractals to fit to the canvas and adjusting gray levels.
Writes Portable GrayMap images with bit depth 8 or 16, or raw pixel hit counts in pseudo-PGM format (like PGM but with 32bit depth).
Can rotate, skew, asymmetricaly scale or flip the fractal before rendering or exporting to another format
Allows selection of speed/quality trade-off and gamma (darkness) modification.
Keeps consistent image impression the same when changing size or the number of iterations (quality).
Can estimate box-counting dimension of the fractals.
Its functionality is available as a library, libifsgr.

What's New in This Release:
The code should be 64-bit clean now.
