John Cupitt 574be4380e revert sharpen restoring the input colourspace
icc_export can make _RGB images, so the input can be outside the set of
supported colourspace transforms.

See 46212e92b1 (r34904985)

bump version too.

John Cupitt 46212e92b1 fix default sharpen
sharpen with sigma 0.5 was doing nothing, since the new int precision
rules meant that we generated a point-point convolution.

This patch increases the int precision for sharpen, so we now work with
sigma down to 0.5.

Also: restore input colourspace. Previously, the output image was always
LabS (the computation space for sharpen). Now, it transforms back to the
input space. This is more in line with how other operators work.

Thanks 2h4dl for pointing this out.

John Cupitt ed2054dbbc revise arithmetic with const
there's a problem with out of bounds values, for example:

	vips relational_const k2.jpg x.v equal 1000

actually finds pixels == 255, since 1000 is saturated converted to 255
before the test starts.

This patch reworks arithmetic against const values to fix this.

John Cupitt 2c654060f9 experiment with a different early-close strategy
We close loaders early in order to save file handles, and on Windows to
make sure that files can be deleted as soon as possible.

Currently loaders do this by watching the Y coordinate of requests and
freeing the fd when the final line of the file is fetched. This is messy
and does not always work, since there are cases when the final line is
not fetched.

Instead, this patch gets loaders to listen for "minimise" on their
output and close on that. This signal is emitted on all upstream images
whenever a threadpool finishes a scan of an image and is usually used to
trim caches after computation.

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.

By default librsvg blocks SVGs > 10MB for security. This patch adds an

We have to switch to using gio to get the librsvg API for this This

John Cupitt bb75535151 much faster ismagick

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 ac4897abee Fix up vips_text()
Fixes two issues:

1. vips_text() in autofit mode could set the wrong DPI, since it set the
DPI in its own copy of the variable, but did not do a final update on
the DPI setting that FT uses for rendering.

2. vips_text() in autofit mode allocated a new context each time, rather
than reusing the context for that call. This caused a small memory leak.

libjpeg rounds up on shrink-on-load. In some cases this can leave a dark

output.

John Cupitt aebb8af803 create funcs always make MULTIBAND
Before, they could make B_W for one-band output. This caused problems
with (for example) two black image bandjoined: the second band then
looked like an alpha to hasalpha() and enabled premultiply/unpremultiply
for operations like affine.

Now, it's always MULTIBAND. This is the generic multiband image type, so
you don't get any unexpected alpha handling.
2018-04-04 09:22:57 +01:00
John Cupitt 0dd6b095aa more conservative hasalpha
The result of hasalpha is used to turn on things like
premultiplication, so we should be rather conservative
about when we signal this. We don't want to premultiply
things that should not be premultiplied.

Check Type as well as bands.

John Cupitt 29e05dabaf icc_import attaches the input profile if used
icc_import can take a fallback input profile in case the embedded one is
broken or missing. If we use the fallback profile, this change attaches
it to the output image.

This means that icc_import will always output an image with the icc
profile that was used to import it. This helps to make the behaviour of
`thumbnail` more consistent.

John Cupitt eefb2dad98 improve rounding in convi intize
We were rounding up with ceil() when intize-ing convolution masks.
However, the vector path has a true range of (1.0, -1.0], so a mask with
1.0 as the max (for example) was actually triggering the overflow detector
and falling back to the C path.

Round up with ceil(x + 1) instead, so 1.0 (for example) will be mapped
to 0.5 and won't overflow.

John Cupitt 01eed391ab add sync locks to vips_sink()
vips_sink() used to just fire off threads willy nilly -- this could
cause problems with sequential images if a worker fell too far behind
the pack

copy over the area locking mechanism from vips_sink_memory(): new
threads are now stalled if an old thread has not finished
2018-01-31 16:25:06 +00:00

John Cupitt 24c07cfde2 revert an accidental ABI break
the new window manager code in 8.6.1 changed the prototype of an internal
function which was visible in the public API

this patch renames the function, adds it to an internal header instead,
and adds a stub for the old prototype
