ImageGrab has built-in support for Microsoft Windows only: https://github.com/python-imaging/Pillow/blob/2.2.1/PIL/ImageGrab.py#L29 https://github.com/python-imaging/Pillow/blob/2.2.1/_imaging.c#L3365 https://github.com/python-imaging/Pillow/blob/2.2.1/display.c#L313 A Tk canvas supports saving to a PostScript file, if that suffices (i.e. if you can render PostScript as an image): canvas.postscript(file='filename.ps', colormode='color') http://www.tcl.tk/man/tcl8.5/TkCmd/canvas.htm#M51 OS X includes a screencapture utility that you could call with the subprocess module: http://ss64.com/osx/screencapture.html This answer on Stack Overflow uses the OS X CoreGraphics API: http://stackoverflow.com/a/13026264/205580 http://pythonhosted.org/pyobjc/apinotes/Quartz.html Or you could switch to a GUI toolkit with better support for saving images, such as Qt: https://qt-project.org/doc/qt-4.8/qpixmap.html https://qt-project.org/doc/qt-4.8/qpainter.html Here's a really basic example using PyQt4. Clicking on the "Capture" button paints the widget to a pixmap that's then saved to "spam.png" and the desktop to "screenshot.jpg" with 95% quality. import sys from PyQt4 import QtCore, QtGui class Spam(QtGui.QWidget): def __init__(self): super(Spam, self).__init__() self.setGeometry(100, 100, 300, 225) self.setWindowTitle("Spam") self.btncap = QtGui.QPushButton("Capture", self) self.btncap.clicked.connect(self.capture) self.show() def paintEvent(self, event): p = QtGui.QPainter(self) p.setFont(QtGui.QFont("Times", 20)) flags = QtCore.Qt.AlignBottom | QtCore.Qt.AlignRight p.drawText(event.rect(), flags, "Spam") def capture(self): wid = app.desktop().winId() QtGui.QPixmap.grabWidget(self).save( "spam.png", "png") QtGui.QPixmap.grabWindow(wid).save( "screenshot.jpg", "jpg", 95) if __name__ == "__main__": app = QtGui.QApplication(sys.argv) spam = Spam() sys.exit(app.exec_()) _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
