This library is a wrapper around Leptonica.
Before you can use this library, it has do be registered with BridJ:
BridJ.setNativeLibraryFile("leptonica",
Paths.get("path/to/liblept.so").toFile()); // alternatively "liblept.dll"Note: This is platform specific. Ensure you set the right path for the right platform or let your users do it for you.
When the library has been set up, you can use it:
// create a 640x480 with 8 bits per pixel (grayscale)
Pointer<Pix> ppix = LibLept.pixCreate(640, 480, 8);
// do something with it
// destroy the pix when you don't need it any more
LibLept.pixDestroy(Pointer.pointerToPointer(ppix));You can convert a BufferedImage to an instance of Pix and vice versa:
BufferedImage img = ImageIO.read(Paths.get("input.png").toFile());
Pointer<Pix> ppix = PixConversions.img2pix(img);
BufferedImage img2 = PixConversions.pix2img(ppix);
LibLept.pixDestroy(Pointer.pointerToPointer(ppix));It is released under the same license as Leptonica, the 2-clause BSD license:
