Geometric Operation
Applying basic geometric operation on an image can be uniform and non-uniform. Some example like resizing, mirroring and rotating are uniform geometric operation while stretching, shearing/skewing and warping are non-uniform geometric operation.


Uniform and Non-Uniform Geometric Operations:
 
 

For the effect below, resize(width x height) function use to resize the actual image
dimension of 300 x 346 pixels to 380 x 438 pixels.
It is notably that the image is being enlarge.


Before Resize
After Resize
Dimension:
300 x 346 Pixels
Dimension:
380 x 438 Pixels

 
The mirror function reverses the image horizontally, so that what was the left side becomes the right and vice-versa.

 
 
This image is being rotated to right with 10 degrees. Then applied image arithmetic effect with substract function, all channels.

 
 
Skew/Shear. This image used the skew/shear function to produce another image. It is skew horizontally.

 
 
Wind. A pre-defined warping from Paint Shop Pro 5, it is very similar to motion-blur.

 
 
For this image, first the image is being mirror. Then combining both the mirror and actual images by the use of image arithmetic with add function, all channels.

 
 
A combination of two pre-defined warping of circle and cylinder-vertical effect to produce this special image.

 
 
Another example of warping of circle and perspective-vertical effect.
