I have a screenshot which contains extra whitespace I need to. e.g per the ruler on the lefthand side of the MS Paint screen:
I have valid content from 0 to 200.
I have unneeded whitespace from 200 to 250.
I have more valid content from 250 to 400.
How can I "cut" those 50 units (pixels?) from the screenshot? In other words, i need the content from 250 to 400 to "move up" to be at 200 to 350. The resultant screenshot would now be 350 units tall instead of 400.
Apologies for not including the screenshot; however, it's proprietary and not easily scrubbed.
