    <p>How can I extract the page dimensions from a PDF file with a C++ program ?</p> <p>Is there any lightweight, cross-platform, easy to build/install, library that could help ?</p> <p>Thanks :)</p> <p>[EDIT]</p> <p>I tried to build podofo under windows, but it didn't work. LibHaru and PDFHummus are for rendering pdfs, not parsing their data.</p> <p><strong>[EDIT &amp; SOLUTION]</strong></p> <p>I've finally built podofo under windows!</p> <p>(btw, under Ubuntu, it was just a matter of <code>sudo apt-get install libpodofo0.9.0 libpodofo-dev libpodofo-utils</code> )</p> <p>It was actually a CMake 2.8.10 bug, switching back to 2.8.3 solved the problem ( <a href="http://www.daniweb.com/software-development/cpp/threads/438435/windres.exe-invalid-option-w-" rel="nofollow">thanks</a> )</p> <p>If anyone is interested, here's how to get started with podofo under windows (I'll demonstrate how to build the debug/shared version):</p> <ol> <li>download the required libraries (freetype, jpeg, openssl, tiff, zlib) and install them (I suggest, copying all the files under <code>LIB_NAME\lib</code> in <code>C:\libraries\lib</code> , same thing for <code>\include</code> )</li> <li>install <a href="http://www.cmake.org/files/v2.8/" rel="nofollow">CMake 2.8.3</a></li> <li>add MinGW\bin and CMake\bin to the <code>PATH</code></li> <li>download <a href="http://podofo.sourceforge.net/download.html#podofo" rel="nofollow">podofo</a> and uzip it somewhere, let's say in <code>C:\downloads\podofo-0.9.2</code></li> <li>create a new directory <code>C:\downloads\podofo-0.9.2\podofo-shared-debug</code></li> <li>open the command prompt then type <code>cd C:\downloads\podofo-0.9.2\podofo-shared-debug</code></li> <li><p>run this command to prepare a MinGW makefile for the debug/shared version of podofo</p> <pre><code>cmake -G "MinGW Makefiles" .. -DCMAKE_INCLUDE_PATH=C:\libraries\include -DCMAKE_LIBRARY_PATH=C:\libraries\lib -DPODOFO_BUILD_SHARED:BOOL=TRUE -DCMAKE_BUILD_TYPE=DEBUG </code></pre></li> <li><p>then just call make</p> <pre><code>mingw-make.exe </code></pre></li> <li><p>if you're using codeblocks, here's how to install/use podofo:</p></li> </ol> <p>9.1. copy the following</p> <pre><code>podofo-0.9.2\podofo --&gt; C:\libraries\podofo-0.9.2\include\podofo podofo-0.9.2\src --&gt; C:\libraries\podofo-0.9.2\include\src podofo-0.9.2\podofo-shared-debug\podofo_config.h --&gt; C:\libraries\podofo-0.9.2\include\podofo_config.h podofo-0.9.2\podofo-shared-debug\src\libpodofo.dll.a --&gt; C:\libraries\podofo-0.9.2\lib-shared-debug\libpodofo.dll.a podofo-0.9.2\podofo-shared-debug\src\libpodofo.dll --&gt; C:\libraries\podofo-0.9.2\bin-shared-debug\libpodofo.dll </code></pre> <p>9.2. use <code>-lpodofo</code> in the linker options then add <code>C:\libraries\podofo-0.9.2\include</code> to the compiler's search directories and <code>C:\libraries\podofo-0.9.2\lib-shared-debug</code> to the linker's search directories</p> <p>Getting back to my initial question, the closest answer to "how to extract the page dimensions from a PDF file with a C++ program (using podofo) ?" is this:</p> <pre><code>#include &lt;iostream&gt; #include &lt;podofo/podofo.h&gt; int main (int argc, char* argv[]) { PoDoFo::PdfMemDocument document; try { document.Load("path/to/the/file.pdf"); } catch (PdfError&amp; e ) { // a password is required to read this pdf return -1; } try { PoDoFo::PdfRect pageSize = document.GetPage(0)-&gt;GetPageSize(); // yes, it's "0-based" std::cout &lt;&lt; "width: " &lt;&lt; pageSize.GetWidth() &lt;&lt; "\t\theight: " &lt;&lt; pageSize.GetHeight() &lt;&lt; std::endl; } catch (PdfError&amp; e ) { // page number error return -2; } return 0; } </code></pre>

    1. COI tried PoDoFo. I spent the last few hours trying to build it under windows, and it simply won't :( I downloaded all the necessary libs (freetype, jpeg, openssl, tiff, zlib). I used cmake-gui to generate the build files for codeblocks. When I tried to build podofo_static there were some build errors... :/

    2. CODid you build all the libs yourself? If you post a question about that I might be able to help.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
