Fonts. dir File Analysis

Nowadays, many people like to build their own linux, and she is more beautiful than before. Setting fonts is a very important step. Many people are setting fonts. when a dir file is stored, it is usually copied directly from someone else. What is the structure of the dir file, or some users do not know how to create a font they prefer, in recent days, I have analyzed this document, and I have written some of my experiences for your reference, I haven't found any specific information in this regard for a long time. The following are my personal opinions. If there is anything wrong, please kindly advise.
Fonts. the first line of dir is generally to tell Xwindows the total number of lines of font information, starting from the second line is the formal font settings information, generally divided into two parts, the first part is the parameter part, it is defined in Part 2. Now I will analyze the following line of font information for your reference:
AB = y: ai =-0.2: sw = 1: bw = 0.5: simsun. ttf-misc-simsun-bold-ro-normal -- 0-0-0-0-0-p-0-gb18030.2000-0
AB = y enables bold characters. By default, AB = n indicates that bold characters are not enabled when not set. It is used together with bold.
Ai =-0.4 tilt the width of a word 0.4 to the left. If ai = 0.4 is the width of a word 0.4 to the right, the default ai = 0. please use it with o or I. Because it is negative here, we also need to use it with r, so ro will be used later.
Sw = 1 the font width is 1 and the default value is 0. this is generally used in combination with the following p. When p is used, the displayed words may be stacked because it occupies the character width, after this is added, the distance between words and words will be opened.
Bw = 0.5 the font width between 0.5 characters. The default value is 0. Suppose you want to use italic, because italic width is relatively wide, for example, if bw =-0.4 above is the width of 0.4 characters left in the top part of the font, we can see the text for convenience, the font width is 0.5 (bw = 0.1), so there is no overlap between words.
Simsun. ttf font file name. This does not need to be explained.
Misc font manufacturer
Simsun font clearly states that we can modify the font as needed. For example, if we change the font to song, we can find the song font when setting the font in Xwindows.
Bold, there is another option medium (normal). If bold is used, add AB = y at the same time.
Ro reverse Oblique, where r (Roman Rome), I (Italic), o (Oblique skew) is reverse Oblique when r and the other two are used together. when I, o, ro, ri, etc. are used, use ai = n, where n = 0.2,-0.2, 0.4,-0.4, and so on. if you do not set ai = n, these will also lose effect.
The width of the normal character set is standard, and condensed, narrow, and double are also condensed)
0 pixel size, the font server will automatically modify, so it is generally 0.
0 point size, same as above.
0 x axis resolution, same as above.
0 y axis resolution, same as above.
The c-Character spacing is c, that is, the distance between one word and p, that is, the character distance.
The average width of 0. The font is automatically modified by the server, so it is generally 0.
Asccii-0 character set for asccii-0, other can also have a lot, such as: gb2312.1980-0, gb18030.2000-1, gb18030.2000-0, gbk-0, etc., specific can see
After analyzing a row, I will write a gb2312.1980-0 font. dir for you to use.
22 // the font of the following 22 characters
