Michael Orlitzky 174a7fe6f9 Fix GH-17891 gh17373.phpt test issue without freetype support 
skip if imagefttext() is not available

This test calls imagefttext(), which may not be available if libgd
was built without freetype support.

Closes GH-17910

Michael Orlitzky 065b4ec125 ext/gd/tests: backport optional PNG support 
- Three of our gd tests could be skipped with a message about requiring
bundled GD, but those tests don't actually require bundled GD. We
update the messages to mention the specific functions that are
required.

- add SKIPIF stanzas for missing PNG support

The bundled libgd always has PNG support, but an external one may not.

- imagerotate() is always available

Following 59ec80c5, the imagerotate() function is always available. We
may therefore remove its function_exists() checks without harm.

Christoph M. Becker 47683487f8 Fix libgd 223: gdImageRotateGeneric() does not properly interpolate 
We port the respective upstream fix[1].  We only run the test against
bundled libgd, since external libgd may yield different results.

Christoph M. Becker ec90367cd8 Fix GH-17373: imagefttext() ignores clipping rect for palette images 
We apply the same fix that has been applied to external libgd at least
as of 2.0.29.

To avoid issues regarding minor FreeType rendering differences, the
test case does not compare against an image, but rather checks that all
pixels outside the clipping rect have the background color.

Christoph M. Becker 2c658f422d Fix GH-17349: Tiled truecolor filling looses single color transparency 
This is porting the relevant part of a previous upstream commit[1] to
align the behavior of our bundled libgd with upstream.  It should be
noted that this only works if the image actually has a transparent
color.

Christoph M. Becker 643a77dda3 Port fix for libgd bug 276 
The issue that BMP RLE occasionally swallowed some pixels[1] had been
fixed long ago in libgd, but apparently it has been overlooked to port
it to our bundled libgd.

We also introduce the test helper `test_image_equals_image()` which
compares in-memory images for equality.

Christoph M. Becker 6727f548b0 Port "gd2: use existing overflow2() rather than ad-hoc version" (#15090) 
We port this modification[1] from libgd into our bundled libgd, because
the change makes sense, and we want the code bases to stay in sync as
close as possible.

We also apply a quick fix to the respective test.

 2024-07-14 13:40:38 +02:00
Christoph M. Becker 02a60be24d Fix skip condition of gh13082.phpt 
The test failure is not particularly related to Travis, but rather is
caused by the GD font file to only be suitable for platforms where
`int` stores 32bit values in little endian byte order.  This platform
dependence is documented in the source code[1].  Thus we fix the skip
condition and skip reason accordingly.

An alternative would be to dynamically create the font file just before
running the test, but that appears to be overkill.
