* docs: Fix a few typosTim Gates2021-09-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | There are small typos in: - examples/copyrotated.c - src/gd.c - src/gd.h - src/gd_avif.c - src/gd_nnquant.c - src/gd_tga.c - src/gd_topal.c - src/wbmp.c - tests/avif/compare_avif_to_png.c Fixes: - Should read `requires` rather than `reqiures`. - Should read `of the` rather than `ofthe`. - Should read `memory` rather than `memmory`. - Should read `maximum` rather than `maxmum`. - Should read `intersection` rather than `intertersection`. - Should read `hypotenuse` rather than `hypothenus`. - Should read `flexibility` rather than `flexibilty`. - Should read `always` rather than `alwasy`. - Should read `also` rather than `alos`.

* AVIF support (#671)Ben Morss2021-03-034-0/+268
| | | | | | | | | | | | | | | | | | | | | | | Demand for AVIF support on the web is growing, as the word gets out about this new file format which allows higher-quality encoding at smaller sizes. Core contributors to major open-source CMSs are interested in auto-generating AVIF images! They've been simply waiting for support to appear in libgd. This PR aims to meet the growing demand, and to help bring smaller, more beautiful images to more of the web - to sites created by experienced developers and CMS users alike. This PR adds support by incorporating libavif in addition to the existing libheif support. It's generally felt that libavif has more complete support for the AVIF format. libavif is also used by the Chromium project and squoosh.app. In this PR, I've endeavored to incorporate the latest research into best practices for AVIF encoding - not just for default quantizer values, but also an algorithm for determining the number of horizontal tiles, vertical tiles, and threads. Fixes #557.
* Remove Git ident attributesPeter Kokot2018-06-278-10/+0
| | | | | | | | Git ident attributes were in most cases utilized with SVN and keywords substitutions, where $Id$ were replaced with certain revision from the repository. In Git this functionality is different. Each $Id$ needs to be defined in .gitattributes file to be effective. This patch removes unused and outdated attributes.
* examples: fix build errors in previous cleanup hereMike Frysinger2018-06-261-4/+9
| | | | | | There was a double paste error in the name "nnquant", and the link line needs to come after we add programs. This was missed locally due to the conditional logic (blah).
* move (redundant) ifdef checks from source to build filesMike Frysinger2018-06-215-39/+14
| | | | | | We've been tracking program deps in the build files, so it ends up being redundant for a lot of our test/example programs. Clean them up, and update some of the cmake/automake files as needed.
* clean up trailing whitespace/newlinesMike Frysinger2018-06-212-2/+2
| | | | | This is preparation for adding some linting checks for new commits from people. Shouldn't be any functional changes here (tests still pass!).
* Fix #440: new_width & new_height exception handlingHaegul Pyun2018-04-181-2/+2
| | | | | Since the cos range is a real number range, there is a possibility of negative numbers. - handling fabs new_width & new_height
* Make BUILD_SHARED_LIBS configurableLeo Yang2015-08-271-3/+9
| | | | | As previously build both shared and static if BUILD_SHARED_LIBS is ON. Otherwise build static only.
