rasterize messes up label to shape mapping when rastering only a subset of shapes
Describe the bug
I ran in an issue when rasterizing shapes to labels. The mapping between labels and shapes seems to be messed up, when rasterize when the coordinate range (min_coordinate, max_coordinate) does not include all shapes.
To Reproduce gist with a MWE
Expected behavior Changing max_coordinate should keep label to shape mapping intact.
Screenshots Just showing some screenshots here, fo the full code, check out the gist above.
Blob data with labeled shapes:
sdata.pl.render_shapes('blobs_polygons', color='position').pl.show()
After rasterizing them and linking the table, I plot them as labels, and this works (max_coordinate for x an y are 512)
However, if I only raster part of the image, the label_index_to_category attribute of the returned label element seems to be messed up. Here, I decresed the max_coordinate for x to 300. In the plot, you can only see part of the shapes, but suddenly, the labels appear mixed:
