在 Kivy 画布上显示 PIL 图像
问题描述
我找不到任何关于如何在 Kivy 画布上显示 PIL 图像的文档.
I can not find any documentation on how to display a PIL Image on a Kivy Canvas.
Rectangle(source=image) give TypeError: 'Image' object has no attribute '__getitem__'
由于其他图像处理，我需要使用枕头图像.我什至尝试将图像加载到纹理中，然后将纹理应用到画布上，但是我不知道如何将格式转换为兼容的格式.关于如何在纹理和画布上加载图像的 Kivy 文档几乎不存在.
I need to use a pillow image due to other image manipulations. I even tried to load the image into a texture then apply the texture to the canvas but then I can't figure out how to convert the formats into something compatible. The Kivy documentation on how to load images on both textures and canvases is pretty much non-existent.
解决方案
from kivy.core.image import Image as CoreImage
from kivy.uix.image import Image as kiImage
from PIL import Image, ImageDraw, ImageFont
from io import BytesIO
canvas_img = Image.new('RGB', (240, 120), color=(255, 255, 255))
(do stuff to canvas_img)
data = BytesIO()
canvas_img.save(data, format='png')
data.seek(0) # yes you actually need this
im = CoreImage(BytesIO(data.read()), ext='png')
self.beeld = kiImage() # only use this line in first code instance
self.beeld.texture = im.texture
