'Centric' image cropping?

Post by jerohm »

Nevermind ... figured it out with Gimp 2.6 :)

Toolbox->Rectangular Select Tool
Tools->Tranform Tools->Crop
Crop Menu->[ ]Expand from Center (toggle off)
View->Zoom->Zoom In (as necessary)
Eyeball select center
Crop Menu->[x]Expand from Center (toggle on)
View->Zoom->Fit Image to Window
Expand to edges; [Enter]

(Thanks anyway)


Does any one know a program (preferably free) or technique to centrically crop an image (for use as a Sprite) such that you can select the point on the image that will reside at (0,0) of the GF screen. I know I can do a reasonable job eyeballing it and using a calculator, but I would THINK there must be an easier way... Technically it should involve establishing the center point and creating a crop selection box where each of the four corners (x,y) exists as:
abs(-x) == x
and
abs(-y) == y
(pardon my notation... but you get what I mean, right???)

that make sense???
Thanks

Nothing I know of that is free. I did this once and used a grid that I constructed in Corel or Adobe's paint progam. Because these programs use preciesly controlled grids, I could correlate that crop (circle or any oval) to a grid supimposed on the actual photographic image, and then to the formula in a G Force config. Then I could also use the natural reversal of GForce sprites to change from a black to white hold-back matt.

I remember there was somthing that you have to correlate between the photo's resolution, dpi and the screen resoltion of the monitor to make this work. It was a pain to set up, but once I got it it worked.

That's the only way I could figure a way to correlate between that circle holdback of a Sprite and a formula for the same area on the screen in GForce.

Hope I understood the question correctly.
