在网页中常常需要使用索引模式的图像。 ⑥Bitmap(位图)色彩模式 位图模式的图像只有黑色与白色两种像素组成,每一个像素用“位”来表示。“位”只有两种状态:0表示有点,1表示无点。位图模式主要用于早期不能识别颜色和灰度的设备。如果需要表示灰度,则需要通过点的抖动来模拟。 位图模式通常用于文字识别,如果扫描需要使用OCR(光学文字识别)技术识别的图像文件

Vector适用于ICON、Button、ImageView的图标等小的ICON,或者是需要的动画效果,由于Bitmap在GPU中有缓存功能,而Vector并没有,所以Vector图像不能做频繁的重绘 Vector图像过于复杂时,不仅仅要注意绘制效率,初始化效率也是需要考虑的重要因素 SVG加载速度会快于PNG,但渲染速度会慢于PNG,毕竟PNG有硬件加速,但平均下来,加载...
Early computer models used lines and coordinates to display simple imagery. These computers couldn’t display raster or bitmap images because of their limited memory. These limitations lead to the development of vector graphics as the solution. Almost immediately, the US Department of Defense began ...
