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.

John Cupitt d1dd41a21f strict round down on jpeg shrink
libjpeg rounds up on shrink-on-load. In some cases this can leave a dark
line along the right and bottom edge, since it only contains (for
example) 1/4 of a pixel of data.

This change adds a crop after jpeg load so that only complete pixels are
output.

John Cupitt 06802e4110 use O_TMPFILE, if available
If O_TNMPFILE is available, use it. This is a linux extension that
creates an unlinked file, so it'll be closed by the system when the last
associated fd is closed.

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 e686614f2c drop incompatible profiles from save
libpng has started throwing hard errors if the profile does not match
the image -- this can happen all the time with perofiles inherited from
images that have been processed.

Test profiles before save and drop them (with a warning) if they are
incompatible with the image.

John Cupitt 5176b4a17e better header sniffing for small files
vips__get_bytes() used to fail if the file was too small for the
allocated buffer, which was a problem for svg, since files can be extremely
small.

This change makes vips__get_bytes() return the number of bytes read, so
the is_a testers can work on files smaller than the max header size.

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.
