CSS rendering is an interesting topic and all the competitors are thriving hard to speed up the view layer (HTML and CSS) rendering to deliver the best results to the end users at a blink of an eye. Firstly, yes different browsers have their own CSS parser/Rendering engines Google Chrome, Opera (from version 15) – … Read more
‘Faster’ is a hard thing to answer because there are many possible interpretations and situations: Base64 encoding will expand the image by a third, which will increase bandwidth utilization. On the other hand, including it in the file will remove another GET round trip to the server. So, a pipe with great throughput but poor … Read more
DOM quality text on the Canvas. A closer look If you zoom in on the DOM text you will see the following (top is canvas, bottom is DOM, center is hopefully at pixel size (not on retina displays)) As you can see there are coloured sections on the bottom text. This is because it has … Read more
Use one way flow syntax property binding: <div [innerHTML]=”comment”></div> From angular docs: “Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script> tag but keeps safe content such as the <b> element.”
I think it is more concise and understandable to describe the performance characteristics of each panel than it is to try to give an absolute relative performance comparison. WPF makes two passes when rendering content: Measure and Arrange. Each panel has different performance characteristics for each of these two passes. The performance of the measure … Read more
As you already know, the problem arises from a different approach to subpixel calculus between browsers In Chrome, for instance, borders can have a fractional size, but margins are handled different (as integers). I don’t have documentation about it from the Chrome team, but it’s what can be seen in dev tools: AFAIK, there is … Read more
As far as I know, OpenCV VideoWriter has no support for HEVC encoding (yet). I recommend you using FFmpeg as sub-process, and PIPE the rendered frames to stdin input stream of ffmpeg. You may use Python binding for ffmpeg like ffmpeg-python, or execute ffmpeg using Python subprocess. Using ffmpeg, you have much more control over … Read more
I’m wondering if there’s a way I can globally scale everything up in my game without either having to scale each sprite up individually […]” No there is no way. You have to scale each coordinate, each size and each surface individually. PyGame is made for images (Surfaces) and shapes in pixel units. Anyway up … Read more
This is a minimal sample application which mixes OpenGL code and QPainter in paint handler: #include <QtWidgets> #include <QOpenGLFunctions_1_1> // manually added types (normally provided by glib) typedef unsigned guint; typedef unsigned char guint8; extern const struct Image { guint width; guint height; guint bytes_per_pixel; /* 3:RGB, 4:RGBA */ guint8 pixel_data[1]; } fluffyCat; class GLWidget: … Read more
This a kind of task WPF is not very good at. I mean vector graphics in general. Thanks to the retained mode. It’s good for controls rendering, but not for the busy graphs which you update a lot. I struggled with the same problem trying to render GPS tracks on a WPF map. I’d suggest … Read more
