Why do I get Error: /invalidfileaccess in --file--

问题

Based on Simple way to add an image in postscript I wrote the following:

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

but this gives:

Error: /invalidfileaccess in --file--

What is going wrong here?

回答1:

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.

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.
