crop an image?

[jftuga]

I would like to write a program to crop an image by using imagemagick on the back-end to do the actual file manipulation and au3 for the front-end. The AutoIt UI would consist of loading a jpg with GUICtrlCreateGraphic() (or is there a better way?). Once this is loaded onto the screen, the user would click 2 points, upper left and lower right. A rectangle would be drawn with GUICtrlSetGraphic() on top of the image so that the user can see what has been cropped. Unfortunately, these 2 functions are incompatible. How can I do this in AutoIt? Once I get the 2 coordinates, then I can use RunWait() and pass these numbers off to the imagemagick convert program.

Any help would be greatly appreciated.

Thanks,

-John

I'd have a look at PaulIA's A3L library in the Example Scripts personally.... dig through those to see if you can mesh together what you are looking at doing.

Personally I would go for the ImageMagick solution :

Using the Crop command

-crop width{%}
-crop widthxheight{+-}x{+-}y{%}

ImageMagick

ptrex,

I agree about using imagemagick. But I would like to have a visual AU3 frontend to make it easier to get the coordinates. Once the user clicks on these (upperleft & bottomright), I can pass these values to the imagemagick command-line program via RunWait().

Any ideas on how to do this?

Thanks,

If I could manage to dig through ElTorro's 2000 lines of code:

http://www.autoitscript.com/forum/index.ph...mp;hl=rectangle

I would:

1. Create a GUI

2. Load the image into the gui

3. Use the selection portion of eltorros code to get the X1,Y1 + X2,Y2

4. Feed the data into ImageMagick
