How to batch process multiple json files of labelme?

[jannatbedi]

I have a folder which consists of the images as well as their corresponding json files generated via labelme. I want to generate the label.png of all these files with a single command instead of running a command for each individual json file. How do I do that?

Use labelme2voc.py in the examples folders.

There are many type of json_to_dataset.py to generate all your json files on CSDN.
but I found that the color changed and some can't matched...
@wkentaro By the way, could I change target parts color? I just watched the issue #216 but I still don't know how to fix this problem, I just need gray and white label.
Looking forward to your help and much thx!

Oh sorry. my English is poor.
I mean that I get same problem with issue #216, and I left a comment under issue #217

@openXG OK. You can change colormap here:

labelme/examples/semantic_segmentation/labelme2voc.py

Line 54 in caa54a7

colormap = labelme.utils.label_colormap(255)

labelme/examples/semantic_segmentation/labelme2voc.py

Lines 84 to 85 in caa54a7

	viz = labelme.utils.draw_label(
	lbl, img, class_names, colormap=colormap)

be deep grateful!
