preivew image in the middle of canvas

[ashraf fawzy]

Hi all ,

I want to load an image and preivew it on a canvas in the middle , How can I do that ??

pic=graphics.Image.open("c:\\data\\logo.jpg")
left = (canvas.size[0]/2)/2
top = (canvas.size[1]/2)/2
img2 = pic.resize((canvas.size[0]/2,canvas.size[1]/2),(left,top)) # this gives error ?!
canvas.blit(img2)

As allways... WHAT error?...

But if you check the documentation, you will see that .resize has the following arguments: resize( newsize[, callback=None, keepaspect=0])

You have the newsize right, but the rest are totally wrong.
This should work: img2 = pic.resize(canvas.size[0]/2,canvas.size[1]/2)

So how can I set the image in the middle of the canvas ??

well you can do the resize on the fly ( faster, but worser quality )
canvas.blit( image, source = ((x1,y1),(x2,y2)) , target = ((x1,y1),(x2,y2)) )

how to find out the x and y coordinates ?
math + brain

Although the end of your answer seems to be sarcastic, but thanks for your help.

By the way , Do you know how can we load contact thumbnail ?? I want to fetch it and preview it on canvas .

thanks in advance.

Sorry i never used such modules
But i can give you a very good advice:
Get the python reference book and look up all the functions of the modules you wanna use. There you can find usefull stuff, if not then you have one last chance to get to your target:
custom C++ extension
