Pechkin HTML to PDF that includes a link to an extensionless PNG

问题 I'm trying to convert an HTML string to PDF using Pechkin Synchronised (WkHtmlToPDF). Everything works perfectly apart from one (deal breaking) part. As part of the HTML string I have an Image tag that references a dynamically generated PNG file over SSL (See below for code). It simply appears as a blank box in the output pdf. I've checked the docs and turned on every option I can think of and have seen references to WkHtmlToPDF being able to support PNG format and pull data from SSL'd

Rotativa / Wkhtmltopdf images not displaying

问题 I am currently creating an MVC 4 web application. I have an action that has a base background image which is always the same then an arrow image which changes in degrees depending on the information that is collected within the action. I call this action using <img src="@Url.Action("trend-image", "NonReg_Reports")" alt="background" width="245" height="105" /> This works fine when it is called and is just displaying a HTML webpage. It gives me the HTML. <img src="/nonreg-report/01495344/trend

跨平台导PDF，结合wkhtmltopdf很顺手

前言 好东西要分享，之前一直在使用wkhtmltopdf进行pdf文件的生成，常用的方式就是先安装wkhtmltopdf，然后在程序中用命令的方式将对应的html生成pdf文件，简单而且方便；但重复的编码使得想在wkhtmltopdf基础上进行封装，偶然间发现有小伙伴已经封装的还不错啦，常用的功能都已经实现，源码地址：https://github.com/fpanaccia/Wkhtmltopdf.NetCore。 作者将其打包成Nuget包(Wkhtmltopdf.NetCore)，直接引入使用即可； 正文 既然用到了.NetCore，肯定就要考虑到跨平台兼容性，对于wkhtmltopdf之前一直是在Windows上使用，还没有在其他平台尝试；这个包封装的行不行，拉出来遛遛就知道啦，接下来就试试： 1. 建个API项目，引入包和兼容对应平台的wkhtmltopdf执行文件 ； 注：默认依赖的wkhtmltopdf执行文件需要存放在Rotativa目录下，可以自定义名称，如果自定义，需要再注册服务时指定对应的文件名；这里的wkhtmltopdf已经根据不同平台进行编译打包了，无需安装，这些文件在源码那就有； 2.创建PDFTestController控制器，添加如下接口进行测试 ； 首先把生成pdf的服务注入进来，后续直接使用就可以啦： 接下来就开始写接口啦，这里只是测试
