PDF rendering with poppler libraries

Dharmender

Hi
I am using the example code posted @http://doc.qt.digia.com/qq/ for Displaying PDF files with qt.
This example works fine and rendering the pdf documents tested this in Ubuntu.

I have cross compiled poppler library for ARM to use in a embedded control panel.
The control panel is able to load the pdf but the font is not rendering.
Can any one help?

Hi and welcome to devnet,

Just an educated guess but did you check that you have all needed fonts installed on your target ?

Hi,

I am using the same code posted http://doc.qt.digia.com/qq/ for displaying PDF with Qt.

It has compiled successfully but when I run, without displaying anything it is exiting by giving the statement as below:
@The program has unexpectedly finished@

Can I know the reason for this?

Thank you.

Hi,

This is the error I get when I run in the debug mode:

@The inferior stopped because it received a signal from the Operating System.
Signal name : SIGABRT
Signal meaning : Aborted
@

Looks like one of my message disappeared…

Anyway, if you have the debugger running it should have stopped at the point of failure.

Where is it ?

ChaitraMohan

When I run debugger it gives the above error message as stated in my previous comment.

SGaist

Are you running a debug build ?

ChaitraMohan

Yes I am running debug build only.

And you don't have a backtrace at the crash point ?

Hi
Please make the following changes.
void Window::openFile()
{

Comment the following code.
/*
QString path = QFileDialog::getOpenFileName(this, tr("Open PDF File"),
/lastPath/"./", tr("PDF files (*.pdf)"));
if (path.isEmpty())
return;
qDebug() << "open file is executing";
char val = getchar();
qDebug() << "getchar executed";
*/
Change the path variable value to "./somedocument.pdf"
documentWidget->setDocument(path);

hope this will help.
