尝试创建
第1步 - 让用户通过Ajax,Raphael和Raphael freetransform上传图像。
第2步 - 点击按钮显示合并上传图片中的一张图片。 (问题):
我找到了关于转换Raphael svg的类似帖子
1
2
3,
所以我也使用Canvg,但得到console.log:Resource interpreted as image but transferred with MIME type text/html
error: image "" not found
。
请帮我找到解决方法。或任何线索如何达到相同的目标(将上传的几个Raphael svg图像转换为一个png / jpeg)?
谢谢!
第1步
// upload images and ajax show in page
var paper = Raphael($('.upload_img')[0], 400, 200);
$('.upload_btn').click(function(){
...
$.ajax({
type: "POST",
url: "index.php",
data: fd,
processData: false,
contentType: false,
success: function(html){
var session = ..., file = ... type = ...;
function register(el) {
// toggle handle
};
var img = new Image();
img.onload = function(){
var r_img = paper.image('img/product/tmp/'+session+'/'+file+type, 0, 0, 200, 200);
register(r_img);
};
img.src = 'img/product/tmp/'+session+'/'+file+type;
}
});
});
第2步
// merge and show
$('.merge_btn').click(function(){
var upload_svg = $('.upload_img').html();
canvg('canvas', upload_svg);
console.log('upload_svg'+upload_svg); //<svg height="200" version="1.1" width="400" xmlns="http://www.w3.org/2000/svg" style="overflow-x: hidden; overflow-y: hidden; position: relative; "><desc></desc><defs></defs><image x="0" y="0" width="200" height="216.91973969631235" preserveAspectRatio="none" href="img/product/tmp/bc4d26ceb620852db36074d351883539/6.jpeg"></image></svg>
// and get error
});
// These code If toggle show Raphael freetransform svg handle, it is work convert several svg handle to one image. but still not found upload image to merge
答案 0 :(得分:1)
如果我没有误认为canvg
函数需要第二个参数为String
,其中包含图像文件的路径。但是,在第2步中,您的代码会执行以下操作:
var upload_svg = $('.upload_img').html(); // **** this does not return the image path
canvg('canvas', upload_svg);
我建议您尝试类似的事情:
var upload_svg = $('.upload_img').attr('src');
canvg('canvas', upload_svg);
这将解释错误 - Resource interpreted as image but transferred with MIME type text/html
- 它需要一张图片,但会收到空白HTML
。其余的代码似乎很好。
