PostScript 'image‘命令在HP LaserJet打印机上的限制是什么？
我尝试将手工构建的PostScript代码插入到pscript5.dll生成的更大文档中。
我使用了从http://paulbourke.net/dataformats/postscript/获得的方法(由于一些奇怪的原因，我以前的代码使用相同的转换矩阵打印4位字符(0.f)，停止工作)。
因此，示例代码是：
100 200 translate
26 34 scale
26 34 8 [26 0 0 -34 0 34]
{<
ffffffffffffffffffffffffffffffffffffffffffffffffffff

image
showpage接着，在HP LaserJet 1320上将源图像(png)转换为1位(从而以'00‘或’FF‘的形式打印每个像素)，我偶然发现了一个奇怪的问题:在图像大小达到128x128到300x450之间时，打印机打印白色矩形而不是预期的图像。测试文件的总大小为2..9 MB。
Ghostscript-9.07解释器正确地显示了更大的插入映像，但是它似乎与HP的嵌入式解释器的实现不同--它仍然与我前面提到的代码工作得很好，软件解释器的放任自流是事实。
有什么可能的方法来解决白方，除了蛮力打印机确定最大。“图像”方法可打印数据大小？
Upd: 300x300已确认可打印，但随机的500x500图像是不可打印的:(在280+字符上断线)没有帮助。

对于非常大的图像，您将开始遇到各种实现限制。常用的限制是字符串、数组和字典中的65535个元素。如果您的图像数据大于64k，则需要将其分割成64k块，并分别送至image (为此目的，image采用过程参数，而不仅仅是字符串数据源)。
如果您只是将数据嵌入其中一次使用，则可以使用标准成语将数据读取到缓冲区中。
/buf 100 string
26 34 8 [26 0 0 -34 0 34]
{ currentfile buf readhexstring }
image
%hex data starts hereimage可以被认为是一个循环运算符，它将不断调用提供的过程以获取更多数据。这个过程甚至不需要返回整行，只需要返回少量的字符串。
