Draw on a ico file without having to convert to png

[MagTun]

What did you do?

Load an ico image, draw lines and save it.

What did you expect to happen?

I expect to get lines on the .ico image

What actually happened?

No lines

The solution

I have to load the .ico image, save it as a png , reload the png and finally draw the line on the png.

Feature request

That would be nice to be able to draw line on .ico files or if it's not possible to implement this workaround on the "back side"

What are your OS, Python and Pillow versions?

• OS: Windows 10
• Python: 3.6
• Pillow: 5.1.0

from PIL import Image, ImageDraw,ImageFont

#create an ico file: this step is just for debug, I already have a `ico` file
img = Image.new('RGB', (50, 50), (125, 167, 242)) 
img.save('a1.ico')  

#code start here
im = Image.open('a1.ico').save('a1.png')
im = Image.open('a1.png')
d = ImageDraw.Draw(im)
d.line((0, 0) + im.size, fill=128)
d.line((0, im.size[1], im.size[0], 0), fill=128)
im.save('pil_modif.ico')

Thanks for reporting this problem. For your immediate use until this is resolved, I can suggest using im.copy() instead of needing to save it and then load it again -

from PIL import Image, ImageDraw,ImageFont

#create an ico file: this step is just for debug, I already have a `ico` file
img = Image.new('RGB', (50, 50), (125, 167, 242)) 
img.save('a1.ico')  

#code start here
im = Image.open('a1.ico')
im = im.copy()
d = ImageDraw.Draw(im)
d.line((0, 0) + im.size, fill=128)
d.line((0, im.size[1], im.size[0], 0), fill=128)
im.save('pil_modif.ico')

Thanks a lot, this is a better way of doing it!

I've created PR #3897 to resolve this.
