If I have

and

need to get

def create_avatar(username):avatar, frame, avatar_id = get_avatar(username)if avatar is not None and frame is not None:try:image = Image.new("RGBA", size)image.putalpha(0)# Paste avatar onto background with positioning offsetimage.paste(avatar, (157, 160), avatar)# image.save('DEBUG-avatar-pasted.png')# Paste frame over avatar and background retaining transarencyimage.paste(frame, (0, 0), frame)except Exception as e:print(e)image = Image.open("images/unknown_avatar.png").resize((512, 512))elif avatar is not None:image = Image.open(f"images/{avatar_id}.png").resize((512, 512))else:image = Image.open("images/unknown_avatar.png").resize((512, 512))image.save(f'images/{username}.png', format='png')

I have a problem with Bad transperancy mask, but need to do that

Output image sizes needs to be 512x512

You are almost there. The problem is that the frame needs to be converted to "RGBA" first.

Consider that the avatar does not need a mask or an alpha channel. You are just pasting a solid image on the canvas image. It's the frame that needs attention in these regards.

from PIL import Imageframe  = Image.open(f"front.png").convert('RGBA')
avatar = Image.open(f"back.jpg")image  = Image.new("RGBA", frame.size, "#00000000")image.paste(avatar, (85, 85))
image.paste(frame, (0, 0), frame)image.resize((512,512)).save('result.png', format='png')
