Question: “The first step I need is to resize images to width’ px width and then automatically crop it to height’’ px height (please see picture with details). What I should do to approach it?” Resolution: Automatic Cropping section describes how to crop images automatically. In this case, images will be cropped first and then converted with a specified mode. However, sometimes user needs to crop already converted image which has width/height different from original ones. Unfortunately, this way is not possible for Image Uploader, but it can be easy bypassed. To approach it, please use the following way: - crop each original image by height divided by width’/height’’ ratio; width of original image should not be changed. Here we use BeforeUpload and BeforePackageUpload events – I will post the script below.
- resize cropped image.
Here is the code of the events: Code:width = [];
height = [];
imageCenterX = [];
imageCenterY = [];
cropWidth = [];
cropHeight = [];
cropBounds = [];
k = [];
function beforeUploadHandler(){
ratio = width’ / height’’;
var count = $au.uploader('Uploader1').files().count();
for (var i = 0; i < count; i++) {
var $file = $au.uploader('Uploader1').files().get(i);
width[i] = $file.width();
height[i] = $file.height();
cropWidth[i] = $file.width();
cropHeight[i] = cropWidth[i] / ratio;
imageCenterX[i] = $file.width() / 2;
imageCenterY[i] = $file.height() / 2;
cropBounds[i] = [(imageCenterX[i] - cropWidth[i]/2),(imageCenterY[i] - cropHeight[i]/2), cropWidth[i], cropHeight[i]];
k[i] = i;
}
}
function beforePackageUploadHandler(){
for (var i = 0; i < k.length; i++) {
var $file = $au.uploader('Uploader1').files().get(i);
$file.cropBounds(cropBounds[i]);
}
}
