没有从GhostScript PDF到PNG转换的输出文件

Question

我有一个两页的PDF我试图转换为PNG文件.当我跑:

gs -sDevice=pngalpha -o=gs-output-%d.png -r400 test1-0.pdf

我明白了:

GPL Ghostscript 9.07 (2013-02-14)
Copyright (C) 2012 Artifex Software, Inc.  All rights reserved.

然后......没什么.根本没有输出文件.我哪里错了？

Answer 1

你太近了,你会发疯;-)

在阅读了一些手册后,这对我有用:

gs -sDEVICE=pngalpha -ogs-output-%d.png -r400 test1-0.pdf

即DEVICE代替Device,而-o不是-o=

如果重要,我的gs版本是:

GPL Ghostscript 9.05 (2012-02-08)
