简介
将图像转换为 ASCII 艺术涉及到转换图像中的每个像素将图像转换为近似其强度或形状的字符。本文探讨了使用 C 进行此转换的两种方法:
基于像素/区域强度(着色):
字符映射:
代码示例:
<code class="c++">AnsiString m = ".,:;ox%#@&"; for (int y = 0; y Height; y++) { for (int x = 0; x Width; x++) { int i = (p[x + x + x + 0] + p[x + x + x + 1] + p[x + x + x + 2]) / 3; i = (i * m.Length()) / 768; s += m[m.Length() - i]; } s += endl; }</code>
分步过程:
代码示例:
<code class="c++">int xs, ys, xf, yf, x, xx, y, yy; int i, i0, d, d0; DWORD **p = NULL, **q = NULL; for (;;) { // Dynamic allocation error handling // Font Properties xf = font->Size; if (xf Height; if (yf Canvas->TextOutA(0, 0, map[x].c); map[x].compute(q, xf, yf, 0, 0); } // Main Loop xf -= xf / 3; xs -= xs % xf; ys -= ys % yf; for (y = 0; y d)) { d0 = d; i0 = i; } } txt += map[i0].c; } break; }</code>
比较和示例:
Approach | Advantage | Disadvantage |
---|---|---|
Intensity-Based | Simple, Fast | Limited Visual Appeal |
Character Fitting | Higher Quality Output | Slower Processing |
