So I am trying to upload an image to the signature capture section, handdrawn value, and I am having an issue with one file. When I upload the file and view it in the Admin section, it shows just a solid black line and not the full image like I expect.
Are there any certain requirements like image size or whatnot that would be causing this issue?
Could you share the image to email@example.com if it doesn’t contains sensitive information? When you convert the image to base64 string (I assume you were using the .Net dll I shared to you in previous thread), there’ll be a threshold value for RGB average determining whether to draw the pixel, which could be a reason in your case.
According to our discussion in private thread, I think the reason causing the short output is the background color of your uploaded image.
It seems that in the .Net dll code, it can’t recognize transparent background, and once I opened and re-saved it in Windows Paint Application, the background color becomes white and everything works fine afterwards.
