问题 I am trying to layout a table in reportLab in the following format. The table is dynamic and can have many rows. --------- | a | b | |---| | | a | | |---| | | a | | --------- tTableStyle=[ ('SPAN',(1,0),(1,-1)) ] Works beautifully if the table fits on one page but crashes if the table is split over pages. Without the span the table splits ok but I'm stuck with the gridlines in the second column. Have read here that this is due to the algorithm used not being able to SPAN across pages

问题 I have an incoming jpg file, that I can set a colour to transparent. When I add the image to another image, this works perfectly. I am trying to add the same image to a PDF using iTextSharp, but I cannot get the transparency to work. I have tried two ways, but neither is working. The first way was to open the image in a Bitmap, set transparency, then use that Bitmap object in the PDF. The second way (shown here) was saving the Bitmap to disk and opening the file into the iTextSharp image.

问题 I am using a webapp on azure to create a PDF using PDFsharp 1.32. As it is a Azure webapp I cannot install fonts. Therefore I am using the following with embedded font options: var globalFontCollection = XPrivateFontCollection.Global; _fontBytes = File.ReadAllBytes(_pathToFont); globalFontCollection.AddFont(_fontBytes, _fontName); However this does not work. There is no error just acts as if the font is not known and falls back to the default. If I install the font it works so I know the rest

问题 For an application I am working on, we have a feature where we are generating a report for an object on the server side, and opening it in a new tab (for the time being) on the client. I'm using the URL.createObjectURL function to make a URL for a Blob , which is comprised of the results of an AJAX call. Whenever a $window.open(generatedFileUrl) call is made, however, I recieve a JavaScript error. Controller: (function() { angular.module('app').controller('someCtrl', [ '$window', 'someSvc',
