How to build from source code

If you want to view EXIF data attached to images, you need the libexif library version >= 0.5.12.

If the libtiff library is present you can save images in TIFF format.

If the libjpeg library is present you have more saving options for the JPEG format and the rotate jpeg tool is implemented internally otherwise it is implemented calling the external command jpegtran.

If the libgphoto2 library version >= 2.1.3 is present you can import photos from your camera.
