* | | Return void from php_jpeg_emit_message()Nikita Popov2020-06-191-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | Instead of returning long and then casting to void. This fixes a build warning on Ubuntu 20.04. Closes GH-5742.

| | | | | | | | | | | | | | | We have to loop over all image pixels to avoid the black border. This is also done in external libgd in `_gdScaleOneAxis` and `_gdScalePass`.

* | | Fix [-Wtype-limits] in bundled GD lib by using signed integersGeorge Peter Banyard2020-02-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As seen in the gdImageRotateBicubicFixed() function the same setup occurs but it uses signed integers, therefore we use also use signed integers in gdImageRotateBilinear() Moreover, these two functions have been removed upstream in https://github.com/libgd/libgd/commit/bd6d2e101f6f1df106d1cd2e2dc8058a5538109b therefore we should also mimic upstream and remove them... Thanks to @cmb69 for pointing it out.
* | | Make error messages more consistent by fixing capitalizationMáté Kocsis2020-01-173-4/+4
| | | | | | | | | | | | Closes GH-5066 As a first step, let's capitalize their initial letter when it is applicable.

* | | Add imagegetinterpolation()Christoph M. Becker2020-01-141-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While `imagesetinterpolation()` is available as of PHP 5.5.0, there is no according getter function, so users would have to track the current interpolation method manually. To remedy this, we introduce `imagegetinterpolation()` as thin wrapper for `gdImageGetInterpolationMethod()` (which has been introduced with libgd 2.1.1), and use `im->interpolation_id` as fallback for older libgd. Since our bundled libgd does not yet have this function, we add it. We also simplify the recently introduced bug79068.phpt, where it is sufficient to check that the interpolation method has not been changed.
* | | Avoid superfluous assignmentsChristoph M. Becker2020-01-091-2/+0
| | | | | | | | | | | | These values are already set via the initializers.
* | | Fix hypothetical segfault in gdTransformAffineCopy()Christoph M. Becker2020-01-061-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | This has been reported to upstream[1], but since ext/gd never calls `gdTransformAffineCopy()` for a palette image, it is not a bug for PHP. Therefore we apply the fix to master only. [1] <https://github.com/libgd/libgd/issues/586>

| | | | | | | | | | | | | | | | | | | | | | | | Apparently, this has not been tested for a long time, and might be a refactoring relict. Anyhow, we have to pass the context to `GIFNextPixel` as well.

| | | | | | | | | | | | | | | If we're compiling the bundled libgd, `HAVE_GD_BUNDLED` is set, so there is no need to check for this macro again.

* | | Support TGA readingChristoph M. Becker2019-06-203-0/+416
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
