I've searched everywhere for two days now, still no help.
my project uses jQuery Guillotine Plugin to allow users select image size and position before uploading to my php server but i can't figure out the proper way to crop and scale the image based on the data received from the frontend.
Here is what i've tried:
The response i'm trying to work with looks like this:
{ scale: 0.324, angle: 0, x: 110, y: 34, w: 300, h: 300 }
Then the php code:
$imagick = Image::make($destination . "/" . $fileName);
$height = $imagick->height();
$width = $imagick->width();
$imagick->rotate($req['angle']);
//using the data recieved after user selection
$imagick->cropImage((int)$req['w'], (int)$req['h'], (int)$req['x'], (int)$req['y']);
//Write image to disk
$imagick->save($destinationPathSmaller . $fileName);
At this point, the picture doesn't display correctly. i really don't know what to do, this is my 3rd day on this. please help!
Thanks in inadvance,
Okay, so i finally got it working.
I thank everyone that tried to help, here is what i did in case someone else is faced with same issue:
Using Intervention and Imagick as the driver.
After collecting your data from the guillotine API, process it and use it like this.
$imagick = Image::make($destination . "/" . $fileName);
$width = $imagick->width() * $req['scale'];
$imagick->rotate($req['angle']);
$imagick->widen($width);
//Crop to desired width and height.
//Note: the width and height has to be same with what you set on your Guillotine config when instantiating it.
$imagick->crop($req['w'], $req['h'], $req['x'], $req['y']);
//Finally, Save your file
$imagick->save($new_destination . $fileName);
That should just work perfectly.
I'm not sure if it's just a different in copying and pasting but I think this may be a simple misusage of the library.
For one. You have this line:
$imagick = new Image($destination . "/" . $fileName);
But they suggest that you use
$imagick = Image::make($destination . "/" . $fileName);
The difference between the two is that a driver is not getting set if you simply call new Image. So the crop method simply bounces off the AbstractDriver class they have and does nothing. But you can call Image::make and it will return the driver.
If that doesn't seem to be the case then I also noticed that you're using writeImage. PHP Interventions method for creating a file based on changes is ->save();. I couldn't find the method writeImage anywhere.
