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.

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.

See https://github.com/libvips/libvips/issues/1351

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.

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.

675c6361eb revise page-height rules again 
Only set `page-height` if `n` is set as an argument. This means you only

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
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.

Merge pull request #1240 from jtorresfabra/fix_hidden_threapool_leak 
Fix for hidden leaks in ThreadPool
 2019-02-27 13:41:17 +00:00
jtorresfabra
8c8affab7f ThreadPool was allocating memory for threads and pools locally to the image object. As that image could not be freed from cache, for each sink operation done for that image the code was creating new pools and threads without freeing the previous one. SO the more number of threads and the more operations the bigger the hidden leak was. The fix just creates the objects not locally to that image, and also free them in its destroy functions 2019-02-27 13:01:45 +01:00

2968bee3fa add n-pages metadata to gifload 
gifload was not setting the n-pages metadata item.

n-pages is supposed to be the number of pages in the original file (not
the number of pages libvips loaded), but we don't always know this for
gif, since you have to decode the entire file to count the pages.

As a compromise, set it to the page number of the final page we read.

ImageMagick supports binary metadata with `ResetImageProfileIterator()`
etc.

some others.
