剪裁预览
你可以对选择的剪裁区域进行预览
$('#image-1').rcrop({
minSize : [200,200],
preserveAspectRatio : true,
preview : {
display: true,
size : [100,100],
}
});
事件和方法
Here you can see an example of using 'rcrop-change' and 'rcrop-ready' events. Also, 'getValues' and 'resize' methods are used.
Fill 'x' or 'y' fields with 'center' to center crop area, or use numbers.
var $image2 = $('#image-2'),
$update = $('#update'),
inputs = {
x : $('#x'),
y : $('#y'),
width : $('#width'),
height : $('#height')
},
fill = function(){
$image2.rcrop('updateCropData');
var values = $image2.rcrop('getValues');
for(var coord in inputs){
inputs[coord].val(values[coord]);
}
};
// Initilize
$image2.rcrop();
// Fill inputs when Responsive Cropper is ready and when crop area is being resized or dragged
$image2.on('rcrop-change rcrop-ready', fill);
// Call resize method when button is clicked
$update.click(function(){
$image2.rcrop('resize', inputs.width.val(), inputs.height.val(), inputs.x.val(), inputs.y.val());
});
事件和方法 (2)
You can add a listener to 'rcrop-changed' event. Also, you can get DataURL of the selected area
$('#image-3').rcrop({
minSize : [200,200],
preserveAspectRatio : true,
preview : {
display: true,
size : [100,100],
wrapper : '#custom-preview-wrapper'
}
});
$('#image-3').on('rcrop-changed', function(){
var srcOriginal = $(this).rcrop('getDataURL');
var srcResized = $(this).rcrop('getDataURL', 50,50);
$('#cropped-original').append('<img src="'+srcOriginal+'">');
$('#cropped-resized').append('<img src="'+srcResized+'">');
})
Images resized (50x50)
Images not resized (original size)
