inkscape_tools

Tools to extract images from SVG files using Inkscape, either to create icons or game sprites

This tool uses Inkscape to prepare assets for Nit applications from a single SVG file. It selects objects to extract from the SVG file when their id begins with 0.

It will produce two files:

• A Nit source file that declares a single class with an attribute for each selected object. The attribute usually holds a single texture, except if the the id ends with a digit, then it will be an array.

• A single PNG image file that contains all the selected objects. With the option --pow2, the image size is rounded to the next of 2.

Usage

1. Create a new Inkscape document.
2. Create objects and set their ids to begin with 0.
3. Save the document to drawing.svg (for this example), the name of the file is used to name the Nit class.
4. Execute bin/svg_to_png_and_nit drawing.svg
5. From your code, import the generated source file at src/drawing.nit.
6. Use the class DrawingImages and its attributes.

Examples

The minimal test in tests/app/ shows the basic usage of this tool.

The Dino example ../../../../examples/mnit_dino also uses this tool and is a more complete and practical example.
