    <p>I'm trying to do individual pixel manipulation using PIL's ImageDraw Module. The code bellow is supposed to create Tkinter canvas widget. Then open an image, change one pixel's color to red, then embed the image in the canvas widget. However, it doesn't seem to be working.</p> <p>My Code:</p> <pre><code>import Tkinter from PIL import ImageTk, Image, ImageDraw class image_manip(Tkinter.Tk): def __init__(self): Tkinter.Tk.__init__(self) self.configure(bg='red') self.ImbImage = Tkinter.Canvas(self, highlightthickness=0, bd=0, bg='blue') self.ImbImage.pack() im = Image.open(r'C:\Python26\Suite\test.png') print im.format, im.size, im.mode im = ImageDraw.Draw(im) im = im.point((0, 0), fill="red") self.i = ImageTk.PhotoImage(im) self.ImbImage.create_image(139, 59, image=self.i) def run(): image_manip().mainloop() if __name__ == "__main__": run() </code></pre> <p>I get the following error upon running my code:</p> <pre><code>Exception AttributeError: "PhotoImage instance has no attribute '_PhotoImage__photo'" in &lt;bound method PhotoImage.__del__ of &lt;PIL.ImageTk.PhotoImage instance at 0x05DF7698&gt;&gt; ignored Traceback (most recent call last): File "&lt;string&gt;", line 245, in run_nodebug File "C:\Python26\Suite\test_image.py", line 30, in &lt;module&gt; run() File "C:\Python26\Suite\test_image.py", line 28, in run image_manip().mainloop() File "C:\Python26\Suite\test_image.py", line 20, in __init__ self.i = ImageTk.PhotoImage(im) File "C:\Python26\lib\site-packages\PIL\ImageTk.py", line 109, in __init__ mode = Image.getmodebase(mode) File "C:\Python26\lib\site-packages\PIL\Image.py", line 245, in getmodebase return ImageMode.getmode(mode).basemode File "C:\Python26\lib\site-packages\PIL\ImageMode.py", line 50, in getmode return _modes[mode] KeyError: None </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
