Paper: De-rendering Stylized Texts

I find that you use a func named 'sample_text_type_flags' in 'class OffsetSampler(object)' to define the angle. But it always return 0, maybe it is a error?

when I run this python gen.py --bgtype=color, there is a error: [D 220704 06:56:21 handler:78] placement False [D 220704 06:56:21 gen_mode:105] 10, 0, 10000 Traceback (most recent call last): File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/handler.py", line 32, in sample_and_render placed = self.sampler.sample(ih, dh) File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/sampler.py", line 71, in sample style_data = self.style_sampler.sample(ih, dh) File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/sampler_lib/style_sampler.py", line 30, in sample effect_params = self.get_style_params( File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/sampler_lib/style_sampler.py", line 21, in get_style_params grad_param = skp.get_gradation_param( File "/home/yonghui_li/Image_generate/derendering-text/src/skia_lib/skia_paintor.py", line 85, in get_gradation_param color = get_color() NameError: name 'get_color' is not defined Traceback (most recent call last): File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/handler.py", line 32, in sample_and_render placed = self.sampler.sample(ih, dh) File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/sampler.py", line 71, in sample style_data = self.style_sampler.sample(ih, dh) File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/sampler_lib/style_sampler.py", line 30, in sample effect_params = self.get_style_params( File "/home/yonghui_li/Image_generate/derendering-text/src/modules/generator/src/sampler_lib/style_sampler.py", line 21, in get_style_params grad_param = skp.get_gradation_param( File "/home/yonghui_li/Image_generate/derendering-text/src/skia_lib/skia_paintor.py", line 85, in get_gradation_param color = get_color() NameError: name 'get_color' is not defined

As you can see, some word images are out of the border, I think maybe there is a error in offset_sampler.py. I try to solve it, but there is still errors.

Thank you for publishing the great work!

There are some mistakes in the bibtex in README.md. The bibtex in the following link will be helpful. https://openaccess.thecvf.com/content/ICCV2021/html/Shimoda_De-Rendering_Stylized_Texts_ICCV_2021_paper.html

I appreciate the provided code and tried myself.

For the prerendering script python -m util_lib.gen_pams

Following resize code causes error: https://github.com/CyberAgentAILab/derendering-text/blob/0273325a29054cb16a4b4d30466f837df6c62b10/util_lib/gen_pams.py#L95

This is beause why alpha_crop = crop_alpha_area(alpha) results some (0,n) or (n,0) shaped array, therefore resize is impossible. To deal with this, I temporarily altered code and checked how this issue as following:

and this is following logs:

Is this ok? Looks like lots of crop errors occur and result resizing error.
