阅读更多关于 Creating an HTML report with embedded screenshots of failed JUnit tests

问题 I've put together a custom JUnit runner that saves a screenshot when a WebDriver test fails. I'm using Maven's failsafe plugin to create reports of the integration tests and TeamCity is our CI server. I know TeamCity supports custom reports, but I don't know how I'd embed the image files into an HTML page (or pages) with references to the relevant tests.

问题 I would like to create Thumbnail from my wpf window and would like to save it into database and display it later. Is there any good solution?

RenderTargetBitmap bmp = new RenderTargetBitmap(180, 180, 96, 96, PixelFormats.Pbgra32); bmp.Render(myWpfWindow); Using user32.dll and Graphics.CopyFromScreen() is not good for me and as it is here because I want to do a screenshot from user controls as well.

three.js toDataURL PNG is black

阅读更多关于 three.js toDataURL PNG is black

问题 I'm trying to grab a screenshot with renderer.domElement.toDataURL("image/png"), and save it to a file. The image is the right size, but it's black. I have preserveDrawingBuffer turned on. I think I'm decoding and saving the file correctly, because when I hexdump it I can see the correct initial characters for the PNG format, as well as the IHDR and IDAT chunk headers. However the closing IEND is missing. Any known issues here? Hints? Windows 7/Firefox up to date if it matters. Thanks...
