Python: Can you add text to an image in python?

BrianK · 04-03-2008, 01:52 PM

Can I use python to put text on an image, like "Property of me" or the file name something of the sort? What about multiple bits of text, like "proeprty of" AND the file name in separate corners of the image?

I know I can do it with imagemagick, I'm just wondering if I can do it directly inside of python (without calling an external program).

The Python Imaging Library should be able to do such...

indeed.

If anyone else is interested, here's my quick example (complete with transparency):

Code:

import Image, ImageDraw, ImageFont
from os import chdir, path

def txt2img(text,bg="#ffffff",fg="#000000",font="Verdana.ttf",FontSize=14):
    font_dir = "/usr/share/fonts/truetype/msttcorefonts/"
    img_name = "sweet.jpg"
    font_size = FontSize
    fnt = ImageFont.truetype(font_dir+font, font_size)
    lineWidth = 20
    img = Image.open("ayo20.jpg")
    imgbg = Image.new('RGBA', img.size, "#000000") # make an entirely black image
    mask = Image.new('L',img.size,"#000000")       # make a mask that masks out all
    draw = ImageDraw.Draw(img)                     # setup to draw on the main image
    drawmask = ImageDraw.Draw(mask)                # setup to draw on the mask
    drawmask.line((0, lineWidth/2, img.size[0],lineWidth/2),
                  fill="#999999", width=10)        # draw a line on the mask to allow some bg through
    img.paste(imgbg, mask=mask)                    # put the (somewhat) transparent bg on the main
    draw.text((10,0), text, font=fnt, fill=bg)      # add some text to the main
    del draw 
    img.save(img_name,"JPEG",quality=100)  



txt2img("This is a really weird image")
