在PySide2中使用自定义图像提供程序处理16位灰度图像

from PySide2.QtCore import Qt, QSize
from PySide2.QtGui import QImage, QPixmap, QPaintDevice
from PySide2.QtWidgets import QApplication, QLabel

class CustomImageProvider(QPaintDevice):
    def __init__(self):
        super().__init__()

    def paintEngine(self):
        return None

    def imageFormats(self):
        return ['gray16']

    def requestImage(self, id, size, requestedSize):
        # 处理图像的逻辑
        image = QImage(requestedSize, QImage.Format_Grayscale16)
        # 在这里对16位灰度图像进行处理
        # ...

        return image

app = QApplication([])
image_provider = CustomImageProvider()
app.addImageProvider('custom', image_provider)

label = QLabel()
label.setPixmap(QPixmap.fromImage(QImage('image://custom/id')))
