Source Image Cropping

[matthewnau]

Feature Outline:

Define an optional argument that allows users to crop their source image by a specified amount of pixels. This crop would work from the outside-in and apply to all 4 sides of the image.

This option should be non-destructive and only factor in as an additional step in the rendering process, therefore leaving the original image untouched. Should the user find the output unsatisfactory, they can then run the operation again with a different value without having to reacquire the source image.

Argument Syntax Example:

-crop 15 (value is set in pixels)

Additional Notes:

• Consider allowing the user to crop only specific sides (left, right, top, bottom)
• Consider allowing the user to crop each side a different amount (e.g. -crop-left 10 -crop-right 15 -crop-top 5)
• Consider how inheritance of cropping factors in. If a user specified a default -crop 15 and a -crop-left 10 would all sides be cropped by 15px except for the left which would then be cropped by 10px?
