It can also be used for splitting and merging files, creating PDF files but you have to supply all the content yourself , and inspecting files for study or analysis.

QPDF does not render PDFs or perform text extraction, and it does not contain higher-level interfaces for working with page contents. It is a low-level tool for working with the structure of PDF files and can be a valuable tool for anyone who wants to do programmatic or command-line-based manipulation of PDF files.

At your option, you may continue to consider qpdf to be licensed under those terms. Please see the manual for additional information. The Artistic License appears in the file Artistic To compile and link something with qpdf, you can use pkg-config with package name libqpdf or cmake with package name qpdf.

Here’s an example of a CMakeLists. QPDF depends on the external libraries zlib and jpeg. The libjpeg-turbo library is also known to work since it is compatible with the regular jpeg library, and QPDF doesn’t use any interfaces that aren’t present in the straight jpeg8 API.

These are part of every Linux distribution and are readily available. Download information appears in the documentation. This is discussed more in Crypto providers below. Detailed information appears in the manual. QPDF makes use of zlib and jpeg libraries for its functionality. These packages can be downloaded separately from their own download locations. These can be selected at compile time or at runtime.

The native crypto implementations that were used in all versions prior to 9. The default behavior is for cmake to discover which other crypto providers can be supported based on available external libraries, to build all available external crypto providers, and to use an external provider as the default over the native one.

By default, the native crypto provider will be used only if no external providers are available. This behavior can be changed with various cmake options as described in the manual. Starting with version 11, qpdf builds with cmake. The default configuration with cmake works on most systems. On Windows, you can build qpdf with Visual Studio using cmake without having any additional tools installed.

Installation can be done with cmake –install. Packages can be made with cpack. The tests use qtest , and the test driver is invoked by ctest. To see the real underlying tests, run ctest –verbose so that you can see qtest ‘s output. For additional information, please refer to the manual. Both bit and bit versions work. The sources to the user manual can be found in the manual directory. For more detailed information, consult the Building and Installing QPDF section of the manual or consult the build-doc script.

They support static and dynamic linking. In general, you do not need the header files from qpdf’s dependencies to be available to builds that use qpdf. Since this is a rare case, qpdf’s cmake and pkg-config files do not automatically add a JPEG include path to the build.

These are the best sources of documentation on the API. There are additional example programs in the examples directory. By default, slow tests and tests that require dependencies beyond those needed to build qpdf are disabled.

Slow tests include image comparison tests and large file tests. On Windows, this should be a Windows path e. The test suite provides nearly full coverage even without these tests.

Unless you are making deep changes to the library that would impact the contents of the generated PDF files or testing this on a new platform for the first time, there is no real reason to run these tests. If you’re just running the test suite to make sure that qpdf works for your build, the default tests are adequate. This way, if the test suite fails, test failure detail will be included in the build output. Otherwise, you will have to have access to the qtest.

The Debian packages for qpdf enable this option. More notes for packagers can be found in the manual. By default, qpdf uses the crypto provider for generating random numbers. The rest of this applies only if you are using the native crypto provider. If none of these conditions are true, the build will fail with an error. This behavior can be modified in several ways:.
