问题 I am building a PHP application where the user upload Powerpoint files. I want the other users to view it online instead of downloading. (Using a third party apps like google docs might be a little cumbersome for the users) Is it possible to write a powerpoint viewer code in PHP? 回答1: You could automate the process of using google docs with php. Google provides a ppt viewer that can be embed into webpages using the following code <iframe src="http://docs.google.com/gview?url=http://www

问题 JavaScript cannot create files locally on the clients filesystem. However, I am wondering, if it is possible to somehow create a Powerpoint MIME in a web page (a div or a iframe) from some JSON and then let the UserAgent figure out it is Powerpoint in the expectation that the UserAgent will offer the user the choice to display it as a powerpoint presentation? Note: The idea here is to be able to take some JSON and make a powerpoint presentation without having to make a request to a Server to

问题 I currently have a PDF embedded into an webpage. The PDF has several hyperlinks within it, but the links open in the parent frame when clicked. This takes the user to a new page with no option to return to the original PDF (navigation turned off). I can't seem to figure out how to get the links to open in a new window. Sample PDF <embed src="https://www.antennahouse.com/XSLsample/pdf/sample-link_1.pdf" type="application/pdf" /> Problem Clicking second( External ) link on this PDF will

问题 The rgl R package allows to plot interactive 3D figures and to save these figures in a html document (with the writeWebGL() function). I would like to put such an interactive 3D figure in a PowerPoint presentation. Is it possible ? EDIT: After studying Dieter Menne's answer with the help of Google, my conclusions are the following ones: Currently Luke Tierney's method to convert a 3D graphic to an U3D file and/or an Asymptote file only works for graphics created with the misc3d package, not

问题 Given a PowerPoint presentation in .ppt format, what is the best way to programmatically and using only open source software extract an image representation (in say .jpg or .png ) of each slide in the presentation? The application will run in a Linux server environment, so installing Microsoft Office or Keynote is not an option. The functionality that I want to achieve programmatically is similar to: Keynote's export functionality ( File > Export... > Pictures > JPEG ) PowerPoint's Save As

问题 I am developing an application in VBA. Userforms connect to a COM object that reads an SPSS Statistics SAV file or an SPSS Dimensions MDD file. Part of this application stores metadata in an XML document so that we can retrieve the metadata later and repopulate or update the graphics created from the userforms. This works fine as long as we rely on an XML file existing on a local drive - which is not a desirable solution. We would prefer to embed (not link) the XML in to the PPTM file, which

问题 I am using the Apache POI library to create powerpoint slides with Java. Our client is interested in embedded text, images and videos. No fancy stuff like charts etc. is needed for now. I understand that XSLF is still under development and not yet a mature product. I have achieved my target using Apache POI HSLF model but the only thing it is missing is that videos which are embedded doesn't show up any playback controls. After little researching I found that it is the pptx and ppt file

问题 I am using LibreOffice installed on my Linux box and I seem to be having a weird problem in that the conversion seems to be taking place, and there seem to be no errors, but there is no output file in the specified output directory. Here is an example of the command I am using: /opt/libreoffice3.6/program/soffice --headless --invisible --convert-to pdf /dir/file.pptx --outdir /dir And here is the result of that command: convert /dir/file.pptx -> /dir/file.pdf using impress_pdf_Export But the

问题 I have some c# code which opens a Powerpoint slide, refreshes the graphs, and then quits. This works fine, unless the user already has a Powerpoint slide open, in which case it will close down their existing session (losing any changes they may have made!) once the exe has run. So, the issue is if you have PPT’s open in the background, run my EXE which runs the below code (opening up a template, refreshing some graphs, saving and closing), upon application exit it disposes of the variable
