Here's a port of leptonica. This port is a new required dependency for graphics/tesseract so needs to be imported before tesseract can be updated to the latest version.
# pkg_info leptonica Information for inst:leptonica-1.68 Comment: software used in image processing applications Description: Leptonica is a pedagogically-oriented open source site containing software that is broadly useful for image processing and image analysis applications. Featured operations are: - Rasterop (a.k.a. bitblt) - Affine transformations (scaling, translation, rotation, shear) on images of arbitrary pixel depth - Binary and grayscale morphology, rank order, and convolution - Seedfill and connected components - Image transformations combining changes in scale and pixel depth - Pixelwise masking, blending, enhancement, arithmetic ops, etc. Ancillary operations include: - I/O for standard image formats: - Utilities to handle arrays of image-related data types - Utilities for generic stacks, queues, heaps and lists; and for byte queues and arrays of numbers and strings Example applications include: - Octcube-based color quantization, with and without dithering - Modified median-cut color quantization, with and without dithering - Skew determination of text images - Segmentation of page images with mixed text and images - jbig2 unsupervised classifier - Border representations of 1 bit/pixel images and raster conversion for SVG - PostScript wrapping (levels 1, 2) of images for device-independent output - Rendering text on an image - Connectivity-preserving thinning and thickening of 1 bit/pixel images - Line removal from a grayscale sketch - Search for least-cost paths on binary and grayscale images Maintainer: The OpenBSD ports mailing-list <ports@openbsd.org> WWW: http://www.leptonica.com/
