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...
To this end, designers in the digital age often choose between two types of digital images in order to get their point across: bitmap vs. vector graphics. Bitmap images, which are created from different colored pixels, are the more common image type found in digital products and websites. ...
Easily convert JPG, PNG, BMP, GIF bitmap images to SVG, EPS, PDF, AI, DXF vector images with real full-color tracing, online or using the desktop app!

Bit map or Raster images are common images created with pixel-based programs or captured with a camera or scanner. Vector graphics are created with vector software and are common for images that will be applied onto a physical product.
Vector vs. raster: What you need to know Before we get to the differences, what is a vector vs. raster image? Take a look at the breakdown of each below. Raster formats If you use the internet every day, then you encounter raster graphics daily. Also known as a bitmap, a raster im...
Raster and vector graphics formats are both useful in the right situation. Learn the difference, and choose the right one for your next design project.
对于静态矢量,绘图阶段只需执行一次,然后可以缓存为Bitmap。对于动画矢量,就无法进行此优化,因为它们的属性必然会发生变化,需要重新绘制。 将其与像 PNG 这样只需要解码文件内容的位图资源进行比较,这些资源随着时间的推移已经经过高度优化。 这是位图与矢量图的基本权衡。矢量图提供上述好处,但代价是渲染更加昂贵。在 ...
The other benefit to a vector graphic is, because of the fact it is created with mathematics, it is usually a relatively smaller file size than a bitmap image. On the other hand, a raster image is created with hundreds or thousands of tiny dots, called pixels. A pixel cannot be made ...
