Python Forum

there are lots of graphics tools for Python, as my initial search easily shows. the issue i am running into is that these tools (mostly) seem to be for doing things like graphical user interface. i want a tool that lets me create various images entirely in memory and write a file (or stdout in the case of a web programmed image) in a common lossless format like PNG (additional formats may include lossy ones). maybe what i need are 2 tools, one to draw in memory and another to output PNG to an open file (just need to be sure they both understand the same memory format).

suggestions what to look for?

edit1:

i am not making bar charts. so a tool that focuses on making it easy to do bar charts is not a fit for me. what will be drawn is not very specific. it will be a lot of draw a line from x1,y1 to x2,y2 at a specified thickness and make the line not jagged.

edit2:

it looks like Pillow has most of what i want. i should play around with this for a while.

Well, thanks for sharing this stuff with us. I have no idea about this and will surely share it with my sister who has a great interest in photography. I am quite sure this gonna helpful for her.

what is your sister trying to accomplish?

photography is one of my hobbies (i've gone digital though i still have a couple film cameras). i am trying to construct images using programed rules and then store those images in a compressed form. web code (HTML) would then reference these image files. for example i might create a tool that creates what looks like a paper calendar showing a specified month and year maybe with specific marks on the calendar (circles, Xs, scratch marks, specified colors, inserted images) pages.
