cropper.js 上传带坐标的原图
cropper.js uploading the original images with coordinates
我正在使用 cropper.js。我想上传原始图像和裁剪后的坐标(x、y、宽度、高度)而不是裁剪后的图像。这样做的首选方法是什么?
谢谢。
对于这个问题的客户端,这里是我用来打包裁剪框数据并将其发送到服务器的代码。见特别说明:
formData.append('last_crop', JSON.stringify($imageBox.cropper('getCropBoxData')));
$('#crop_button').click(function(){
// Upload cropped image to server if the browser supports `HTMLCanvasElement.toBlob`.
// Store crop coordinates to db for future visit.
var canvas = $imageBox.cropper('getCroppedCanvas');
canvas.toBlob(function (blob) {
var formData = new FormData();
formData.append('croppedImage', blob); // 'croppedImage' is the sent filename
formData.append('last_crop', JSON.stringify($imageBox.cropper('getCropBoxData')));
$.ajax('{% url 'profile_crop_avatar' %}', {
method: "POST",
data: formData,
processData: false,
contentType: false,
success: function () {
console.log('Upload success');
},
error: function () {
console.log('Upload error');
}
});
}, "image/jpeg", 0.75);
// Also update masthead image after crop
$('#masthead-avatar').attr('src', canvas.toDataURL());
});
在服务器端 (Django),我使用以下方法处理和存储坐标:
# Save new image and crop coords to profile
p = request.user
p.last_crop_coords = request.POST.get('last_crop')
p.save()
