在Kivy画布上显示PIL图像 [英] Display PIL Image on Kivy Canvas

问题描述

我找不到有关如何在Kivy画布上显示PIL图像的任何文档.

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__'

由于其他图像操作，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，但后来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.

推荐答案

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
