John Cupitt ff58c67e33 add locks for pdfium load
We used to lock within documents, ie. we did not allow two threads to
work on the same file.

However pdfium is not threadsafe in any way, and this is not supported,
see:

	https://groups.google.com/forum/#!msg/pdfium/kyIdh_J4csg/K1LvfPiHDwAJ

This patch adds locks around pdfium calls.

John Cupitt 5e77ab948b fix loop with malformed ppm
skip_line in ppm parse was not testing for EOF, so it could get stuck
with malformed files

John Cupitt 8cf6a9f9ca don't attempt to save large XMP to JPG
jpeg_write_marker() with some libjpeg versions will throw a fatal
error with large chunks.

To write >64kb XMP it you need to parse the whole XMP object,
pull out the most important fields, code just them into the main
XMP block, then write any remaining XMP objects into a set of
extended XMP markers.

http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/xmp/pdfs/XMPSpecificationPart3.pdf

Instead, just warn and skip large XMP blocks.

John Cupitt 5e2d66d14b better early shutdown behaviour in shrinkv

John Cupitt f45f0ecef4 limit resize if shrink would drop axis <1px
vips_resize() will break the aspect ratio and limit resize on an axis if
it would result in an image of less than 1px on that axis

John Cupitt 26100041e7 fewer warnings on tiffload
We were setting TIFFTAG_JPEGCOLORMODE == JPEGCOLORMODE_RGB for *all*
images, but libtiff warns if you use it on an image which is not
jpg-compressed.

Only set it for jpg-compressed images.

John Cupitt 80648c2d2f text autofit could sometimes underfit
The autofit loop would terminate if either width or height fitted exactly,
but this could happen very early by chance. This patch makes it keep
looping until it finds a dpi which just fits.

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 ad98222073 better behaviour for vips_region_fetch()
we weren't clipping the fetch area against region valid, so in some
cases we could return many more pixels than expected

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 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 394f9baa5e deprecate webpload @shrink, use @scale instead
We need a fractional scale for thumbnail on webp to work well. @shrink
still works, but @scale overrides it.

some others.
