使用ghostscript将PDF转换为TIFF，但不将文件写入磁盘

Question

我知道ghostscript可以将pdf转换为tiff，甚至具有python绑定，但是我想知道是否有一种方法可以避免将生成的tiff写入磁盘（ -SOutputFile=/path/to/file.tiff 。我想保留生成的tiff在内存中并将其用作PIL图像。

Answer 1

Basically, no, not using the standard devices. That's because the strip size of the TIFF file (and potentially other entries in the TIFF header) can't be written until after the compressed bitmap has been created because the sizes aren't known. So you need to be able to seek back to the beginning and update the header.

Now you could modify the standard TIFF output devices so that they maintain the output in memory, rather than writing to disk, but that's not how they currently work.
