为什么会出现错误：--file--中的/ invalidfileaccess [英] Why do I get Error: /invalidfileaccess in --file--

问题描述

基于在后记中添加图像的简单方法我写了以下内容：

gsave
    360 72 translate                            % set lower left of image at (360, 72)
    230 346 scale                               % size of rendered image is 175 points by 47 points
    2304                                        % number of columns per row
    3456                                        % number of rows
    8                                           % bits per color channel (1, 2, 4, or 8)
    [2304 0 0 -3456 0 3456]                     % transform array... maps unit square to pixel
    (graphics/IMG_2216.jpg) (r) file /DCTDecode filter   % opens the file and filters the image data
    false                                       % pull channels from separate sources
    3                                           % 3 color channels (RGB)
    colorimage
grestore

但这给出了：

Error: /invalidfileaccess in --file--

   2304   3456   8   --nostringval--   (graphics/IMG_2216.jpg)   (r)

怎么办

推荐答案

很简单，访问文件存在问题。该文件不存在于指定位置，或者您没有对该文件的访问权。

Quite simply there is a problem accessing the file. Either the file does not exist in the specified location, or you do not have access rights to it.

鉴于您正在打开文件进行读取，最可能的原因是该文件不存在。我注意到您没有使用完全限定的路径，也许您是在错误的位置执行了PostScript。

Given that you are opening the file for read, the most likely is that the file doesn't exist. I notice that you haven't used a fully qualified path, perhaps you are executing the PostScript from the wrong location.
