Title: Thumbnail position - not ceter.
Post by: gcstate on January 16, 2010, 10:30:20 pm

Hello

I wanted to ask if there is way to change properties of where coppermine should crop the thumbnails.
Like i always upload a pictures to my gallery, and mostly people heads are cut of the image, because it make the thumbnail from center.

So i wanted to ask if its possible to somehow set up, that when i Upload a picture, it will automatically crop the thumbnails from top or few pixels from top?
I hope you understand what i mean. If not i will post examples.

Thank you!

after

Code: [Select]

                } else {
                    $ratio = (double)($srcWidth / $thb_width);
are the cases that handle cropping for pics with height < width

im sorry im total noob to this.
so what should i change  height < width or offsety offsetx ?
i dont care about the width or height of the thumbnail right now (my sizes of thumbnails are okay for me). i just need to make the crop from the top of image not center. see the example attached

please help :(

Code: [Select]

$yOffset = round(($srcHeight - $cpyHeight) / 2);change to (2 times)

Code: [Select]

$yOffset = 0;
should do (I guess)
