Extend canvas in one axis without adjusting the other
Hello,
Firstly, I have just downloaded Picture Resizer today and I'm so impressed with this piece of software.
I would like some help though if anybody is able to provide it....
I want to extend the canvas in the following way:
Only adjust the canvas up to the point where the smallest side is 500px and ignore other dimensions if they are already at or more than 500px and with the extended canvas in white.
For example:
If I had an image 370 x 1292 I want the new image to be 500 x 1292.
If I had an image 1100 x 163 I want the new image to be 1100 x 500.
If I had an image 420 x 480 I want the new image to be 500 x 500.
If I had an image 700 x 800 I want it to be ignored (as both sides >500)
The canvas must be white.
Furthermore I'd like it to just replace the exiting image thus maintaining the original image name.
I hope I have explained things clearly and thanks in advance!
