of the three approaches to rendering. We'll go to through them all, but I, let ' s talk about introductory stuff. Remember Sdl_setvideomode ()? It ' s completely gone. SDL 2.0 allows you to have multiple windows, so the "old" function didn ' t make sense no more. So your might have had something like this: Toggle Line Number Display Sdl_wm_setcaption ("My Game Window", "Game"); Sdl_surface *screen = Sdl_setvideomode (640, 0, Sdl_fullscreen | SDL_OPEN

ZYNQ image paths to be used for ZYNQ video-related developers. This post describes a camera +hls image processing +DDR storage +VGA display image path. This channel is I and another colleague to achieve, I am responsible for the camera FPGA driver, HLS image processing IP Implementation and the system later optimization. Because of the company project, it is not possible to provide engineering documents, only to provide the framework and ideas.The system framework is as follows: Key modules i

Mobile phone page Design General size is 640, but, mobile phone screen size is really uncertain, so, how to make the phone to adapt to all mobile page?The general solution has two types, REM layout and percent layout. I have tried both of these options, so it is now more recommended to use the REM layout to make mobile pages;The compatibility of REM layouts:Mozilla Firefox 3.6+, Apple Safari 5+, Google Chrome, ie9+ and opera11+, IE6-IE8 or don't use R

First, mobile device picture blur problemCell phone blur The problem is the difference in the actual pixels that a pixel represents on the computer and on the phone.The PX (independent pixel) units we use in the stylesheet do not necessarily represent the actual one pixel (physical pixel), which depends on the hardware settings. For example, a stolen image below, a separate pixel on the right is equal to four pixels, and a separate pixel on the left is equal to one pixel. Devicepixelratio is the

1. The first one is about mobile-adaptive problems:A: If it is the last time a canvas-generated picture, rather than the canvas that you want to draw, you do not need to consider adaptive, draw canvas when the width of the height, can be directly written to the UI provided by the size of the graph, such as the UI provides a graph is 750 * 1280, When the canvas is drawn, all the data can beTo 375*640 to calculate, fixed good can!
