这篇补充文档列出了 putimage 函数支持的所有三元光栅操作码。
三元光栅操作码定义了源图像与屏幕图像的位合并形式，这个合并形式是以下三个操作数对应像素的布尔运算：
布尔运算符包括以下几种：
| 操作 | 含义 |
|---|
| a | 位的 AND 运算(双目运算) |
| n | 位的 NOT 运算(单目运算) |
| o | 位的 OR 运算(双目运算) |
| x | 位的 XOR 运算(双目运算)
|
所有的布尔操作都采用逆波兰表示法，例如，“当前填充颜色 or 源图像”可表示为：PSo。（当然 SPo 也是等价的，这里只列举出了其中一种等价格式）
三元光栅操作码是 32位int 类型，其高位字是布尔操作索引，低位字是操作码。布尔操作索引的 16 个位中，高 8 位用 0 填充，低 8 位是当前填充颜色、源图像和屏幕的布尔操作结果。例如，PSo 和 DPSoo 的操作索引如下：
| P | S | D | PSo | DPSoo |
|---|
| 0 | 0 | 0 | 0 | 0 |
| 0 | 0 | 1 | 0 | 1 |
| 0 | 1 | 0 | 1 | 1 |
| 0 | 1 | 1 | 1 | 1 |
| 1 | 0 | 0 | 1 | 1 |
| 1 | 0 | 1 | 1 | 1 |
| 1 | 1 | 0 | 1 | 1 |
| 1 | 1 | 1 | 1 | 1 |
| 操作索引: | 00FCh | 00FEh
|
上例中，PSo 的操作索引是 00FC (从下往上读)，DPSoo 的是 00FE。这些值定义了相应的三元光栅操作码在“三元光栅操作码”表格中的位置，PSo 在 252 (00FCh) 行，DPSoo 在 254 (00FEh) 行。常用的三元光栅操作码已经定义了常量名，程序中可以直接使用。
