Vector graphics clipboard format for Qt

由 元气小坏坏 提交于 2020-01-14 07:57:51
问题 I want my Qt application to be able to save simple vector graphics to clipboard in a compatible way. On windows I want to be able to paste the graphics into Microsoft Word or Powerpoint. On Linux I want to be compatible with the Open Office. Which format would you recommend? Can Qt generate EMF in an easy way? Is SVG an option? Update: My current plan is to add a piece of native win32 code to render the graphics to emf on windows. This code will not be available on linux. 回答1: The

Generate vector EMF/WMF (Windows Metafile) clipboard content from Qt 4.5

问题 We are moving a large codebase from GDI to QPainter. One thing we used to get on Windows easily was the EMF clipboard format, which enabled customers to manipulate their pasted output in other programs (like Office) in a vector format. It's easy for us to produce bitmaps from Qt into EMF, but that really doesn't give us back the editability of the old format. We can also make mime data from Postscript, which in some programs will retain vector format, but won't allow editability in Office,

Convert Selected PowerPoint Shapes (or DrawingML) to XAML

由 故事扮演 提交于 2019-12-24 05:28:53
问题 I need to convert selected PowerPoint shapes to XAML so I can effectively place an equivalent vector-based shape inside my WPF app (the XAML end result has to be scalable - converting to an image defeats the purpose of what I'm trying to do). I'm open to a variety of ways to accomplish this, including writing a PowerPoint addin (if this could get me access to the bezier point coordinates of the selected shapes in PowerPoint). I'm not familiar enough with PowerPoint addins to know if this is

rmarkdown vector graphics for knit word

问题 When using rmarkdown with knitr in Rstudio to knit a Microsoft Word document, the graphics generally look crappy because the usual vector graphics formats, such as PDF are not supported in Microsoft Word. Fortunately, the devEMF package in R generates the microsoft vector format EMF, and I almost have this working for my rmarkdown application. The problem is that my image is showing up way too small. How can I control the image size? I've tried the standard things below: --- title: "Plot size

Change resolution of EMF image files to prevent quality loss in PowerPoint

由 感情迁移 提交于 2019-12-13 14:24:33
问题 Exporting .emf (Enhanced Metafile) vector from Illustrator CS5 [and other versions tested] for use in MS office documents such as PowerPoint, can be a right pain. If you export them at a sensible size, the vectors don't have enough points and you end up losing accuracy on your shapes and strokes - so they look very low quality. If you make them bigger in Illustrator before exporting, the filesize remains approximately the same, but the vector accuracy is far better. But when you import into

EMF with forced antialiasing

由 倾然丶 夕夏残阳落幕 提交于 2019-12-06 06:09:59
问题 Our program needs to generate vector graphics, and we chose EMF for that. However, it seems that other programs render these images non-antialiased. I found that SVG format does have a flag to indicate that some/all objects should be antialiased. Is there any kind of flag or command inside the EMF format to indicate that we want to have antialiasing? If so, how to generate that command using System.Drawing.Imaging.Metafile class? Thank you. 回答1: EMF file is a list of GDI commands. So it won't

How to display Windows Metafile?

问题 I need to display a Windows Metafile (EMF) using WPF, how can I do? Edit: I'd to keep the image vector-based. 回答1: Take a look at the 3rd party library Ab2d.ReadWmf. Update #1: Overview First off, this post states that Microsoft does not intend support EMF files in WPF. That doesn't mean it can't be done, just that they will not support them. Looking at the Wikipedia page about the WMF/EMF format I see that it describes EMF as: Essentially, a WMF file stores a list of function calls that have
