Word type description method capable of showing stroke width change

Abstract

The invention refers to a kind of font description method which can present stroke thickness change. The method quotes the concept of writing brush character, the geometry area moves along the stroke and changes its area, when the area is big, the stroke is thick, otherwise thin. Only need to determine the movement route of geometry area central point according to the stroke character, starting control point, ending control point and the area of the geometry, the area moves along the determined route and the region which passed by the area are font.

Description

technical field [0001] The invention relates to a font description method, especially a font description method that can present changes in stroke thickness. Background technique [0002] There are currently three commonly used font description methods, namely: bitmap font, outline font, and vector font. The following three fonts will be introduced. [0003] 1. Dot matrix fonts: dot matrix fonts describe fonts by the presence or absence of pixels. Pixel 2 with slashes represents the font area, and white pixel 4 represents the blank background part outside the font area. , refer to Figure 1A. Therefore, the dot matrix font can be said to be an image file of the font, which can accurately describe the shape of the font at a fixed resolution, and can be easily displayed on the display. However, because the data of each pixel must be stored, the biggest disadvantage is that the amount of data required is very large, and since it is an image file of a font with a fixed size and...

And general Chinese, Japanese, Korean character set has about 7000 to 18000 words, and the required storage space of these character sets single typeface is about 5 to 12 megabytes (Mega bytes, MB), and to Personal Digital Assistant (Personal Digital Assistant) Assistant, PDA), set-top box (Set-Top Box), or mobile phone, etc., due to the limitation of memory capacity, the storage of Chinese, Japanese, and Korean characters will be limited, and it will also cause a great burden on the memory

[0005] 3. Vector font: The vector font uses the control points 8 to describe the turning changes of the stroke centerline 12. Referring to Figure 1C, due to the lack of description of the appearance or thickness of the font, the stroke can only be defined as bold or thin body, etc., so the appearance of the font is not as beautiful as the frame font

[0006] The current trend of computer development is towards portability and compactness. Therefore, when the memory capacity that can be equipped is limited, how to store more fonts and types of fonts in the limited memory space, and describe them delicately? font; and in addition to the limitation of memory capacity, it must take a long time to transmit a huge amount of data under a limited bandwidth
