1.80.0: * Improve bmp handling of 1 bpp images and sanity checking of params. * Add function to display all rgb gamut colors * in Makefile.am, use option serial-tests to avoid races in testing * Make md subdirectory and add ax_split_version.md there * Simple function for hue-invariant mapping (pixMapWithInvariantHue) * Fixed bug in limit of ptra size when used for sorting by bins. * Use hashmap to count pixel colors in RGB(A) images. * Convert hashtest program to regression test hash_reg. * Convert croptest program to regression test crop_reg. * New color segmentation by region growing (colorfill.c) * New regression tests: colorfill_reg, circle_reg, ccbord_reg. * Set maxima for all allocations for common leptonica data structures. * Don't fail when downscaling 2, 4, 8, and 32 bpp images, even to one pixel, invoking pixScaleSmooth(). * New functions that select 1 bpp components based on their area. * Incremental addition to sorted array of numbers. * new prog/fuzzing directory for oss-fuzz based fuzzing programs * use of pixcmapIsValid() with extra argument to determine validity with the pix it is attached to. * Use lept_stderr() in all programs in the prog directory. * New program rasteroptest() for thorough testing of rasterop functions. * Removed the pixSaveTiled*() functions * Stubbed pixDisplayWrite(). Last used in tesseract 3.04.01 (2/2016). |
