Bitmap font
Dot matrix fonts are also called bitmap fonts, and each glyph is presented in the form of two-dimensional pixel information. This display mode has been widely used in early computer systems.
Extended challenge
Because of the bitmap characteristics of dot matrix fonts, dot matrix fonts face challenges in scaling. Dot matrix fonts can only display clear fonts under a certain font size. If you zoom in forcibly, the text will be distorted and show a mosaic-like jagged edge.
8- 14px Chinese font
However, among Chinese fonts of 8- 14px, dot matrix fonts are still widely used in screen display, providing excellent display effect.
vector font
Although dot matrix fonts are mainly used as auxiliary parts now, when there are no bit images in the set font size, the fonts will be displayed in the form of vector images. When printing, regardless of font size, vector fonts will be used for printing.
Font difference
It is important to know the difference between dot matrix fonts and vector fonts. Dot matrix fonts are mainly used for display, and the edges of Chinese characters will appear sawtooth after amplification. Vector fonts retain the descriptive information of each Chinese character, such as the starting and ending coordinates, radius, radian and so on.
Font type
When displaying or printing this font, a series of mathematical operations are needed. Theoretically, the Chinese characters stored in this font can be infinitely enlarged, keeping the outline of strokes smooth. The fonts used by Windows also fall into these two categories. FONts directory has font extension Fon for dot matrix fonts and TTF for vector fonts.
