Hi,
There's two sets of "borders" I think you're talking about. Outside the
yellow box and inside.
For outside, this is the contents margin of the GraphicsLayout -- but
you'll need to get the reference to that from the central item in the
GraphicsLayoutWidget:
self.winImage.ci.setContentsMargins(0, 0, 0, 0)
For inside the yellow box, this is about the extent of the ViewBox
(essentially the plot limits). Set them manually eg:
self.p1.setLimits(xMin=0, 100, yMin=0, yMax=100)
So an example would be:
#!/usr/bin/env python3
import numpy as np
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QVBoxLayout, QHBoxLayout
import pyqtgraph as pg
class TestImage(QtWidgets.QMainWindow):
def __init__(self):
super().__init__()
# Create empty data structure
self.data = np.random.rand(100, 100)
self.winImage = pg.GraphicsLayoutWidget()
self.winImage.ci.setContentsMargins(0, 0, 0, 0)
self.p1 = self.winImage.addPlot()
self.imh = pg.ImageItem(self.data)
self.p1.addItem(self.imh)
self.p1.setMouseEnabled(x=False,y=False)
self.p1.hideAxis('left')
self.p1.hideAxis('bottom')
self.p1.hideButtons()
self.p1.scale(1.0, 1.0)
self.p1.setLimits(xMin=0, xMax=self.data.shape[0], yMin=0, yMax=self
.data.shape[1])
self.setCentralWidget(self.winImage)
def main():
import sys
app = QtWidgets.QApplication(sys.argv)
mainwindow = TestImage()
mainwindow.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
