* Support TGA readingChristoph M. Becker2019-06-201-0/+4
| | | | | | | | | | | We add PHP bindings for libgd's features to read TGA files, which are available as of libgd 2.1.0. As PHP's bundled libgd doesn't yet include the respective features of the external libgd, we add these. Since TGA has no easily recognizable file signature, we don't add TGA support for imagecreatefromstring() or getimagesize() and friends.
* Implemented the gdScatter filter I wrote almost 10 years agoKalle Sommer Nielsen2019-05-101-0/+12
| | | | | | | | | | | | | | | | | | | This filter is available as of libgd 2.1.0 which is our bare minimum for external compilation of ext/gd. The scatter filter works by iterating over all pixels in the image and shifting them randomly based on two modifier (`plus` and `sub`) values: dest_x = (int)(x + ((rand() % (plus - sub)) + sub)); dest_y = (int)(y + ((rand() % (plus - sub)) + sub)); Additionally the scatter filter also supports by only shifting pixels where the current pixel being iterated is one or more colors, allowing the scatter filter to only effect solid colors in part of an image. Note, due to the nature of randomness and implementation, pixels who were shifted ahead of iteration will be shifted once more and therefore the bottom right of an image may contain a slight scatter effect due to this.
* Remove HAVE_SYS_VARARGS_HPeter Kokot2018-09-161-11/+1
| | | | | | | | | | | Outdated systems used to provide the `<varargs.h>` and in case of PHP `<sys/varargs.h>`. [1] Current systems have `<stdarg.h>` which is also a C89 standard header and systems have it always present.

* | Implement #69606: Support BMPs (added in GD 2.1.0)Christoph M. Becker2017-01-041-0/+9
| | | | | | | | | | | | | | | | We add PHP bindings for libgd's features to read and write BMP files, which are available as of libgd 2.1.0. As PHP's bundled libgd doesn't yet include the respective features of the external libgd, we add these.

| * | Implement request #33066: Add GD Image Function gdImageOpenPolygon()Christoph M. Becker2016-10-021-0/+1
| | | | | | | | | | | | | | | | | | gdImageOpenPolygon() has been introduced with líbgd 2.0.29, so we finally add a PHP binding for it, and port the respective libgd functionality to PHP's bundled libgd.
* | | Unify error handling of bundled and external libgdChristoph M. Becker2016-10-071-4/+4
| | | | | | | | | | | | | | | | | | | | | There's no need anymore to call an own error handler directly. Instead we register our error handler and call libgd's error functions (which will forward). We do this regardless of compiling with the bundled or an external libgd.
* | | Change gdImageTrueColorToPalette() to return success/failureChristoph M. Becker2016-10-031-1/+1
|/ / | | | | | | | | | | | | | | We're porting the relevant changes from <https://github.com/libgd/libgd/commit/34a00a40>. We also check the return value in the PHP binding, and throw E_WARNING if the conversion failed.
* | Add support for gdEffectMultiplyChristoph M. Becker2016-10-021-0/+3
| | | | | | | | | | | | | | gdLayerMultiply() has been introduced in libgd 2.1.1, and as such would have been already available for imagelayereffect() with a system libgd. We port the respective code to the bundled libgd, and also make IMG_EFFECT_MULTIPLY available to userland.
* | Switch to libgd anti-aliased drawing APIChristoph M. Becker2016-10-021-2/+0
| | | | | | | | | | | | Instead of rolling our own in the bundled libgd, we use libgd's anti-aliased drawing API. This way imageantialias() is also available, when built against a system libgd.
* | Remove further remains of the old antialiasing supportChristoph M. Becker2016-09-301-15/+2
| | | | | | | | | | | | Curiously, while the external GD claims "just a few vestiges after switching to the fast, memory-cheap implementation from PHP-gd", that stuff was still in the bundled GD.
* | Port variable image resolution support from libgd 2.1.0Christoph M. Becker2016-09-191-0/+5

* imagettftext() uses the last charactermap it found and not the one you wantScott MacVicar2014-02-161-1/+2
| | | | | | | | | | | | Summary: This caused issues when you picked a font with multiple maps, it wouldn't pick the unicode version but instead pick the last one it saw. Change so we cache on a per encoding level. There was even a todo list item in the code. In an ideal world we can probably iterate through at font write time. Test Plan: See said unit test, it's Apache Licensed font included
