Welcome to Rendera

Rendera is an open-source painting program. It was primarily designed with photo restoration in mind, but is also useful as a general painting application.

The tools, shapes, blending modes, edge-wrapping, and cloning may all be combined to suit a particular need. Brushstrokes are rendered after being drawn, allowing for slower, non-realtime calculations to be applied without interfering with the mouse or tablet response.

Features:

  • use any combination of paint, blending, clone, and wrap options
  • crop tool
  • interactive offset (for working on seamless tiles)
  • GIMP palette support with editor
  • high-quality color quantization
  • basic image transforms
  • lots of built-in filters
  • advanced color restoration filters
  • alpha-channel support
  • grid (no snap yet...)
  • PNG, JPEG, BMP, and TGA file formats

    This program is written in C++ and uses the FLTK toolkit.


  • Colorizing a black and white image.
