I have a portrait layout and would like to resize it to:

[480 x 360]
[600 x 450]
[720 x 540]

I have a landscape layout and would like to resize it to:

[360 x 480]
[450 x 600]
[540 x 720]

I do not care about the size! Just make the image:

[75% smaller]
[50% smaller]
[25% smaller]

I would like to rotate the image.

[90° left]
[90° right]
[180° flip]
