I'll use it when I get to it! Thanks! For now, I use this, as suggested by eryk sun: os.startfile('1.bmp') it doesn't pop the window. Thanks Alan! On Thu, May 18, 2017 at 10:06 AM, Alan Gauld via Tutor wrote: > On 18/05/17 16:43, Michael C wrote: > > os.startfile('1.bmp')

Did you go into the source code of PIL/Pillow? Awesome!!! On Wed, May 17, 2017 at 7:52 PM, eryk sun wrote: > On Thu, May 18, 2017 at 1:58 AM, Michael C > wrote: > > when I run this, while it's called test.pyw, this pops up > > > > from PIL

Actually, that is the whole script! I didn't get used to have the cmd.exe window pop up at all, could it be something I did? Or, is there a way to suppress that from showing up? thanks! On Wed, May 17, 2017 at 3:30 PM, eryk sun wrote: > On Wed, May 17, 2017 at 8:24 PM,

Re: [Tutor] Python Image Library

in fact, when I ran this: import os os.system("mspaint 1.bmp") It also opened a cmd.exe window and the script wouldn't continue until I closed the cmd window! On Wed, May 17, 2017 at 1:24 PM, Michael C wrote: > from PIL import Image > > > im =

You know the height and the width of the image, no? So you know that every 'width' number of pixels will start a new row. So if you wanted say the fifth row down, second pixel, how would you find it? The 1st line: 'width' number of pixels The 2nd line: 'width' number of pixels The 3rd line:

Re: [Tutor] Python Image library

if you start counting at the 0th row and 0th column, this will give you the 4th row and 2nd column. if you're counting from the 1st row and 1st column, this will give you the 5th row and 3rd column. That number is the index to use to get the pixel at coords (2,5) So this is actually
