linux - Ghostscript: Convert PDFs to other filetypes without using the filesystem -


I want to use C APIs on ghostscript on Linux to convert PDFs to other things: fewer pages and two PDF examples with images.

My understanding was supplying the callback function with GPS, I could read and read data from them. Although by my experiment and reading, it does not seem like this

My motivation to do this is that I would like to have PDF processing on scale, and do not want my throughput to be held back a spinning disk.

Am I missing something?

The SDDI API allows you to provide your replacement for stdin, stdout and stderr, this No activity is influenced by an interpreter who does not use them.

The pdfwrite tool makes extensive use of the file system to write temporary files, grab the various intermediate parts of the PDF file, as it has been explained, it later rejoined the new PDF file. Are there. Temporary files are not written in stdout or stderr.

There is no way to avoid this behavior.

Using the file system again, unless you specify stdout the destination of bitmap where you can use stdio API calls to redirect stdout elsewhere if the image is high enough resolution If the song is sung, GS will use a display list and then the display list will be stored in a temporary file which will be unaffected by stdio redirection.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
