John Cupitt 72c103f95a Revert "remove no-alpha webp support"
This reverts commit d1094847a3.

John Cupitt d1094847a3 remove no-alpha webp support
We used to try to spot webp images with no alpha and load them as plain
RGB, but it turns out this is difficult to do reliably, especially
for animated images.

This patch simply removes support, so all webp images now load as RGBA.

John Cupitt 75e69cc1e5 disable Orc if CET is on
If we are building with -fcf-protection (run-time checking of
indirect jumps) then Orc won't work. Make sure it's off.

Orc may support -fcf-protection in the future, but does not in June 2019.

John Cupitt dc8555201d use our sniffer as well is ismagick()
We need to check files for magickload with our sniffer as well as the
imagemagick one.
2019-06-08 17:13:49 +01:00
John Cupitt bb75535151 much faster ismagick
We used to Ping files to see if IM would load them, but this can be
extremely slow for file formats like ARW.

Instead, use GetImageMagick() ... it just checks the magic number.
2019-06-08 16:47:40 +01:00
John Cupitt eb6c803481 istiff tests first dir rather than magic number
We were testing for TIFF by checking the magic number at the head of the
file. However, formats like ARW are TIFF-like without being TIFF, and
will not load with tiffload.

Instead, try reading the whole of the first directory. This is enough to
stop tiffload trying to load files where it will simply fail
immediately, and make libvips fall back to eg. imagemagick.

John Cupitt 675c6361eb revise page-height rules again
Only set `page-height` if `n` is set as an argument. This means you only
get a multi-page image if you specifically ask for it.
2019-05-29 14:18:46 +01:00
John Cupitt bd8a6980f5 more consistent behaviour for multi-page load
Some loaders were setting page-height even when the user was loading a
single page triggering unexpected multi-page behaviour from later
savers.

New rule: only set page-height when loading more than one page.

John Cupitt b2ad9f9df8 better compat with older libheif
We were looking for "yes" from the builtin_h265_decoder variable to
enable heifload, but this variable was only added in libheif 1.3, so we
failed to turn on heifload correctly.

We now look for not "no", ie. default on.

John Cupitt 29d29533d4 better pdfload page size rounding
We were doing simple round down for page size with @scale param. But
this makes it very sensitive to rounding errors, so do rint() instead.

vips-resize() does rint() on the output size as well for the same
reason.
