具有位图字体的C头文件 [英] C header file with bitmapped fonts

问题描述

我需要对一个像素缓冲区做一些基本的文本渲染，我认为将一个以char为索引的表格作为一个二进制数组表示字符将会绰绰有余......任何人都知道一个空闲标题例如：

  char data [256] [ 8] [8]; 
 void init（）
 {
 data ['a'] = {
 {0,0,1,1,1,0,0,0}，
 {0,1,0,0,0,1,0,0}，
 {0,0,0,0,0,0,1,0}，
 {0,0， 1,1,1,0,1,0}，
 {0,1,0,0,0,1,1,0}，
 {0,1,0,0,0， 0,1,0}，
 {0,1,0,0,0,1,1,0}，
 {0,0,1,1,1,0,1,0} ，
}; 
} 
  

我可以继续使用字母表的其余部分，但是，不需要问......但这给了我一个主意！如果没有可用的位图字体的空闲头文件，每个答案都可以实现一个字母，我可以在这里组合整个文件^ _ ^

解决方案

更新：我尝试了这种方法，角色相当扭曲。可能Nimbus是一种糟糕的字体选择。

请使用imagemagick方法。您可以使用以下代码生成每个角色：

  convert -resize 7x13 \！ -font Nimbus-Mono-Regular -pointsize 10 label：A.xbm 
  

A.xbm看起来像：

  #define A_width 7 
 #define A_height 13 
 static char A_bits [] = {
 0x00，0x00，0x00，0x00，0x1C，0x08，0x00，0x3C，0x00，0x66，0x00，0x00，
 0x00，}; 
  

循环遍历所需的字符并将其组装到一个头文件中。
$ b

即使Nimbus-Mono-Regular是一个等宽字体，有时字符宽度会被一个像素关闭。转换选项-resize 7x13！强制7x13的输出尺寸。同样，这可能是Nimbus字体的一个特殊问题。

I need to do some rudimentary text rendering to a pixel buffer, and I think that having a table indexed by char with the representation of the letters as a binary array would be more than enough... Anybody knows about a free header as such?

Example:

char data[256][8][8];
void init()
{
  data['a'] = {
    {0,0,1,1,1,0,0,0},
    {0,1,0,0,0,1,0,0},
    {0,0,0,0,0,0,1,0},
    {0,0,1,1,1,0,1,0},
    {0,1,0,0,0,1,1,0},
    {0,1,0,0,0,0,1,0},
    {0,1,0,0,0,1,1,0},
    {0,0,1,1,1,0,1,0},
  };
}

I could go on with the rest of the alphabet, but then I wouldn't need to ask... ¡But that gives me an idea! if there's no free header with a bitmapped font readily available, each answer could implement a letter and I could assemble the whole file here ^_^

解决方案

Update: I tried this approach and the characters come out fairly distorted. Possibly Nimbus is a poor font choice.

Go with the imagemagick approach. You can generate each character with this:

convert -resize 7x13\! -font Nimbus-Mono-Regular -pointsize 10 label:A A.xbm

A.xbm looks like:

#define A_width 7
#define A_height 13
static char A_bits[] = {
  0x00, 0x00, 0x00, 0x00, 0x1C, 0x08, 0x00, 0x3C, 0x00, 0x66, 0x00, 0x00,
  0x00, };

Loop through the characters you need and assemble this into a single header file.

Even though Nimbus-Mono-Regular is a monospace font, sometimes the character widths are off by a pixel. The convert option "-resize 7x13!" forces a 7x13 output size. Again, this might be a problem specifically with the Nimbus font.
