Imagine that you are building a symmetric image using a bunch of basic shapes. To create such an image, an operation that can flip (or mirror) the image would come in handy. So let's see how image flipping can be accomplished.
Write the following code in a Python source file.
1 import Image 2 inPath = "C:\\images\\Flip.png" 3 img = Image.open(inPath) 4 outPath = "C:\\images\\Flip_out.png" 5 foo = img.transpose(Image.FLIP_LEFT_RIGHT) 6 foo.save(outPath)
In this code, the image is flipped horizontally by calling the
transposemethod. To flip the image vertically, replace line 5 in the code with the following:foo = img.transpose(Image.FLIP_TOP_BOTTOM)
The following illustration shows the output of the preceding code when the image is flipped horizontally and vertically.
The same effect can be achieved using the
ImageOpsmodule. To flip the image horizontally, useImageOps.mirror, and to flip the image vertically, useImageOps.flip.import ImageOps # Flip image horizontally...
