This feature is also provided by Photoshop, GIMP, etc.

I hope this is a useful stand-in until a proper line/shape tool becomes available.

PhotoDemon 7.0.1


PhotoDemon is a portable photo editor focused on performance and usability.

It provides a comprehensive photo editor in a 12 MB download. It runs on any Windows machine (XP through Win 10) and it does not require installation. Feel free to run it from a USB stick or portable drive.

PhotoDemon is completely open-source and available under a permissive BSD license. Contributors have translated the program into more than twenty languages.

New contributions from coders, designers, translators, and enthusiasts are always welcome.

What makes PhotoDemon unique?

Lightweight and completely portable

No installer is provided or required. Aside from a temporary folder – which you can specify from the Tools > Options menu – it leaves no trace on your hard drive. Many users run PhotoDemon from a USB stick or portable drive.

Integrated macro recording and batch processing

Complex editing actions can be recorded as macros (similar to Office software). A built-in batch processor lets you apply your macros to entire folders of images.

Usability is paramount

Many open-source photo editors are usability nightmares. PhotoDemon tries not to be. Small touches like save/load presets on all tools, unlimited Undo/Redo, "Fade last action", keyboard accelerators, effect previews, mouse wheel and X-button support, and descriptive menu icons make it fast and easy to use.

Pro-grade features and tools

  • Extensive file format support, including all major RAW formats
  • Color-managed workflow, including full support for embedded ICC profiles
  • Non-destructive editing for select features, including resizing, rotation, and common adjustments
  • 2D transformations: advanced rescale operators (Sinc, Catmull-Rom, etc), content-aware scaling (seam carving), crop, straighten, shear, zoom
  • Adjustment tools: levels, curves, HDR, white balance, split-toning, green screen, Wratten filters, and many more
  • Filters and effects: perspective correction, edge detection, noise removal, content-aware blur, unsharp masking, lens diffraction, vignetting, and many more
  • Some ~200 tools are provided in the current build.


  • PhotoDemon isn't designed for OSes other than Microsoft Windows. A compatibility layer like Wine (http://www.winehq.org/) may allow it to work on OSX, Linux, or BSD systems, but program stability and performance may suffer.
