Python Imaging Library (PIL)

Use the Python Imaging Library (PIL) to add image processing capabilities to your Vizard scripts. You can process an image and then load it as a texture within Vizard. Cutting, pasting, and merging images, rotating and resizing images, and image enhancement are some examples of what you can do.

For a complete description of the commands available within the library refer to the PIL Documentation.

Example

The following example shows how to take a PIL image and use it as a Vizard texture. We create a new PIL image, draw an ellipse onto it, and then add some text. The PIL_TO_VIZARD function then copies this PIL image to a Vizard texture:

import viz
from PIL import Image, ImageDraw

viz.go()

def PIL_TO_VIZARD(image,texture):
    """Copy the PIL image to the Vizard texture"""
    im = image.transpose(Image.FLIP_TOP_BOTTOM)
    texture.setImageData(im.convert('RGB').tobytes(),im.size)

#Create a blank Vizard texture
tex = viz.addBlankTexture([1,1])

#Apply texture to quad
quad = viz.addTexQuad(pos=(0,1.8,2),texture=tex)

#Create a new PIL image and add a shape and text to it
image = Image.new(mode='RGB',size=(200,200),color=(0,0,255))
draw  =  ImageDraw.Draw(image)
draw.ellipse((50,50,150,150),fill=(255,255,255))
draw.text((85,95),'HELLO',fill=(0,0,0))

#Copy PIL image to Vizard texture
PIL_TO_VIZARD(image,tex)
