    <property name="text" translatable="yes">This dialog allows you to automatically convert a raster graphic into vector paths. Several options are available for different use cases:
 * "Brightness cutoff" detects areas that are darker than the threshold value and creates a path enclosing them (using potrace).
 * "Edge detection" detects changes greater than the given threshold value in the brightness of color patches and creates paths to separate them (using potrace).
 * "Color quantization" separates the image into the given number of colors, and separates them with a path (using potrace).
 * "Autotrace" uses the autotrace algorithm with the given option.
 * "Centerline tracing" tries to vectorize a line drawing (with autotrace).
 * "Multicolor" options separate the image into a number of scans, depending on brightness, color separation, or gray levels (using potrace), or using the autotrace algorithm, and create several paths for those.
 * The "Pixel art" tab allows to use an algorithm for pixel recognition or one for depixelizing to vectorize pixel art images.

 * NOTE:
  1) Save your work before tracing
  2) Watch your pixel count: "Trace pixel art" creates up to one path per pixel. It is not recommended for images that are not pixel art.
  3) Autotrace is slower than potrace, it is not recommended for big images. Preprocessing your images to increase contrast is recommended.
  4) If your goal is to get few nodes and good precision, manual tracing is always best.</property>
