How do you change the color of the picels of the picture?

[Rossere]

I want to write a program that would make blur effect. QPixmap♪ QImage

from PyQt4.QtGui import * 
from PyQt4.QtCore import * 
import sys
def main():

app     = QApplication(sys.argv)

window  = QMainWindow()

label   = QLabel(window)

pixmap = QPixmap('myimage.gif')

label.setPixmap(pixmap)

window.setCentralWidget(label)

window.setWindowTitle("Blur Effect Example")

window.show()
sys.exit(app.exec_())

if name == 'main':

main()

How do I change the colors of the pixmap pickles?

We add a button to a pressurization panel that will be in an accidental place with an accidental flower of 20x20:

app = QApplication(sys.argv)
window = QMainWindow()

label = QLabel()

pixmap = QPixmap(label.size())

pixmap.fill(Qt.transparent)
label.setPixmap(pixmap)
window.setCentralWidget(label)

window.setWindowTitle("Blur Effect Example")
def draw_random():

painter = QPainter(label.pixmap())

# or:

# painter = QPainter(pixmap)
painter.setBrush(QColor(randint(0, 0xFF), randint(0, 0xFF), randint(0, 0xFF)))

x, y = randint(0, pixmap.width()), randint(0, pixmap.height())
painter.drawRect(x, y, 20, 20)

label.update()
# or:
# label.setPixmap(pixmap)

general_tool_bar = window.addToolBar('General')

action = general_tool_bar.addAction('Draw Rand Rect')

action.triggered.connect(draw_random)
window.show()
sys.exit(app.exec_())
