I've tried multiple approaches, which work as expected in Chrome/Firefox. I'm working with django, so there will be some templates and some JavaScript. pdf_preview_embed is a div Embed DataURL <embed width=100% height=100% type="application/pdf" src="data:application/pdf;base64, {{ pdf }}"></embed> Unacceptable solution, because it may require inlining megs of data.

Vue 采用blob下载后端返回的excel流文件乱码问题

由 匿名 (未验证) 提交于 2019-12-03 00:42:01
没有文件服务器, 前后端采用文件流方式下载,后端返回二进制乱码时,前端使用blob对象进行处理 2.采用的是axios请求方式 this.$http.post("download", { fileName: file.filename }) .then(function(response) { let blob = new Blob([response.data], {type: ‘application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8‘}); let downloadElement = document.createElement(‘a‘); let href = window.URL.createObjectURL(blob); //创建下载的链接 downloadElement.href = href; downloadElement.download = ‘xxx.xlsx‘; //下载后文件名 document.body.appendChild(downloadElement); downloadElement.click(); //点击下载 document.body.removeChild(downloadElement); //下载完成移除元素 window

caffe inplace 操作

由 匿名 (未验证) 提交于 2019-12-03 00:39:02
所谓的in-place操作，即就地操作，就是说一个函数的输入图像src与输出图像dst是同一图像。 比如，高斯滤波函数GaussianBlur( )支持in-place,那么我们就可以： GaussianBlur(src,src,Size(3,3),2,2); 而不需要： GaussianBlur(src,dst,Size(2,2),2,2); caffe利用in-place计算可以节省内（显）存，同时还可以省去反复申请和释放内存的时间。 相同名字的bottom和top这些blob就是同一个blob，占用的是同一个空间。 简单来解释就是：int a;a = 0 ;a = 1 ;你可以无数次对这个a进行改变。 对于blob来说也是一样。至于谁先谁后，那就是看你的网络定义哪个layer在前，它就先计算。如果有两个layer输出的blob名称是一样的， 那么它们的输入blob也一定会有这个blob ，也就是，如果layer不是对输入blob本身操作，就不允许输出blob同名。 比如：layer1和layer2的输入和输出blob都是blob1，它们都是对blob1进行操作，这是允许的，直接按顺序计算就可以了。 layer1的输入blob是blob1，输出blob是blob_out，layer2的输入blob是blob2，输出blob也是blob_out，那么这就是不允许的。

Difference between CLOB and BLOB from DB2 and Oracle Perspective?

由 六月ゝ 毕业季﹏ 提交于 2019-12-03 00:34:57
问题 I have been pretty much fascinated by these two data types. According to Oracle Docs , they are presented as follows : BLOB : Variable-length binary large object string that can be up to 2GB (2,147,483,647) long. Primarily intended to hold non-traditional data, such as voice or mixed media. BLOB strings are not associated with a character set, as with FOR BIT DATA strings. CLOB : Variable-length character large object string that can be up to 2GB (2,147,483,647) long. A CLOB can store single
