博客配有说明,地址为:http://blog.csdn.net/qq21497936 《Qt实用技巧:测试80*1080p拼接后显示刷新帧率》 1.动态读取exe当前目录下的images\images1-至5下面的图片(菜单选择),图片名称为1.jpg -> 16.jpg 共16张图片 因图片太大,只给了images\images1下一张图片,自行复制为1-16.jpg文件名,且images1-5都需要16张。 2.控制因子,为Factor,其决定读入后的像素,可选1或2,1则不改变,2则除以2,使纵横分辨率减小一半(缺省为1) 3.想测试其他图片,直接更换图片即可,因未做其他处理,会以1.jpg为图片标准尺寸,需要保证1-16.jpg是同一个分辨率的即可 3.目前是40ms间隔丢一次图片(每秒25帧图片),帧率(未做控制)是当前计算机最大的,是两个概念:每秒多少帧图,每秒刷多少次界面 4.目前完成:缩小/放大/抓拖移动 5.当绘制区域越大,fps越小 作者:红模仿 QQ:21497936 版本 日期 描述 1.0.0 2018月2月9日 初步验证技术点,控件未完版本,目标版本1.0 1.0.1 2018年2月10日 修正拼接需求,解决大图片BUG,优化显示方式,目标版本1.0
