Hi!

As so many before me I have to say that the CropCanvas project is so great! The best part is that it's easy to understand and use.

But now to the question:
You have the
Code:
$ci->setCropPositionDefault(ccCENTRE);
where you can insert the initial crop window-position. But is there any way to make it take the sx,sy,ex,ey coordinates so I can choose exactly the crop-window?

I'm storing the coordinates in a DB and when I bring back an image I use the original and not the cropped. But I want the crop-window to be placed where I cropped the image. Maybe not easy to get that one.. But hope you understood Smile

Again thanks for a great project/script!

Hi, and welcome to the board.

By default. no, there isn't a way to do that. However, the initial width/height and position of the cropping area is done in the inc.cropjavascript.php file, with these two lines:

Code:
list($w, $h) = $this->calculateCropDimensions($this->crop['default']);
list($x, $y) = $this->calculateCropPosition($w, $h);


So you could just put something in place of that to get the data from the DB and populate the $x and $y variables (and $w/$h if they are stored, too). Possibly a good idea to default to the above method if the DB cannot be connected to or the data not retrieved for some reason.

Andy

Thank you.

It works! Wasn't that difficult to make. It's been very easy to work with your script Very Happy

for anyone who is curious about how it's done:
Code:

$w = $ex - $sx;
$h = $ey - $sy;
$x = $sx;
$y = $sy;

In stead of:

Code:

list($w, $h) = $this->calculateCropDimensions($this->crop['default']);
list($x, $y) = $this->calculateCropPosition($w, $h);


Again thanks and keep up the great work!
