-= microexr Library =- What the hell is this library ? ------------------------------- This library was started in order to replace the original OpenEXR library for a limited set of capabilities. As of now, this library will let you _write_ multi-channels OpenEXR files in scanline format, with ZIP or ZIPS compression support, as well as EXR 2.0 deep image files. We choose to support only the original OpenEXR C API. We have added one function to enable users to write multi-channel and deep EXRs so that the library is functional (original C API only allows for RGB[A] files). If you are already using the interface designed in "ImfCFile.h", chances are that you can readily link with this library. History and Future ------------------- This library was written for 3Delight in order to provide simple EXR writing routines. Our wish to provide good reading functionalities for the most common EXR layouts. OpenEXR C++ API will not be supported so we will keep updating the original C API. Directory Structure ------------------- README.txt This file. microexr/src Contains the source to the library. microexr/test Contains simple tests that produce EXR and EXR 2.0 file. microexr/tools Contains a couple useful source files but not needed for the library. microexr/build Contains object files (.o files) after the build. microexr/lib Will contain 'libmicroexr.a' after the build. How to Build ------------- Like this (on Linux and Mac Os X): cd microexr/src make Windows not yet tested but as you can see, should be a simple task, for once! To build the test: cd microexr/tools make ./gradient ./deepgradient This generates two gradient files: "gradient.exr" and Dependencies ------------ We will try to keep this to a minimum. Please, no boost, no python, no cmake or other bloat. As of now, we need this: * zlib. For ZIP and ZIPS compression. * stl. For no good reason, could be easily removed.
