I have built a PyQt5, Python 3.7 windows application that uses PyQtGraph to view monochrome (greyscale) Magnetic Resonance DICOM images. As I move the mouse pointer over the image, I would like to display the value of the pixel under the pointer on the window. There is no obvious (to me) functionality in PyQtGraph to do this. I would be very grateful for any suggestions by more experienced developers of how to do this. Here is an edited code segment showing how I display the image (pixelArray) in an MDI subwindow.
layout = QVBoxLayout() widget = QWidget() widget.setLayout(layout) self.subWindow.setWidget(widget) imageViewer = pg.GraphicsLayoutWidget() viewBox = imageViewer.addViewBox() image= pg.ImageItem(border='w') viewBox.addItem(image) imageView = pg.ImageView(view=viewBox, imageItem=image) layout.addWidget(imageView) imageView.setImage(pixelArray) -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
