Stupid art

Approximate an input image by adding random shapes on top of each other in parallel.

Dependencies:

• Futhark

Optional dependencies:

• SDL2 and SDL2-ttf
• FreeImage

Building

To build, first run futhark pkg sync once.

Then run make to build.

• To build without the SDL dependency, instead run STUPIDART_NO_INTERACTIVE=1 make.

• To build without the FreeImage dependency, instead run STUPIDART_NO_FREEIMAGE=1 make. This means you will only be able to read and write images in the Netpbm PAM format. You can use ImageMagick's convert utility to convert from and to this format.

• You can also use the backend-specific LYS_* environment variables mentioned in Lys before make.

Running

Run ./stupidart <input image> <output image> to generate art.

Run ./stupidart --help to see the available options.

Controls for interactive use

Unless you run stupidart -I, you will watch the image as it is generated (note that this is slower than the non-interactive approach due to some internals).

• 1: Generate random shapes (default)
• 2: Generate only triangles
• 3: Generate only circles
• 4: Generate only rectangles
• r: Reset
• Space: Pause/unpause
• F1: Toggle showing the text.
• ESC: Save the current image (always without the text) to the output file and exit.
