John Cupitt a5a3b062fc support saving 1 and 2 band images to webp 
see https://github.com/jcupitt/libvips/issues/267

John Cupitt eda4ed64f1 rename _!PIXEL etc. to help bindings 
ruby gobject-introspection hates numbers at the start of _ separated
names

John Cupitt 6e2135d8b5 mask builders take prec, not integer 
vips_gaussmat() and vips_logmat() used to default to float, but
vips_conv() defaulted to int ... so this failed:

	vips gaussmat m.v 2 0.1 --separable
	vips convsep k2.jpg x.jpg m.v

since we were using a small float mask with an integer convolution

This change makes everything int by default, with gaussmat having a new
param called --precision whose arg can be int or float.

The old @integer param is deprecated.

John Cupitt 620bff2d78 allow symbolic names for flags 
you can now use numbers or names for GFlags values, eg.:

$ vips copy 50020484-00001.png x.png[filter=avg]
$ vips copy 50020484-00001.png x.png[filter=64]

was numbers only before

John Cupitt 154796a8dc rename VIPS_ANGLE_0 as VIPS_ANGLE_D0 
and other similar cases

VIPS_ANGLE_0 becomes Vips.Angle.0 in Python, which is very inconvenient, so we
rename ... the D stands for degrees, I think

John Cupitt de594151a5 rename NOTEQUAL as NOTEQ

John Cupitt c4a3e9a1a0 add VIPS_ARGUMENT_MODIFY

John Cupitt f8dddf23a9 remove disp stuff, just sRGB now 
all the old monitor calibration stuff is gone, we only support sRGB now

im_Lab2disp() etc. have become vips_Lab2sRGB() etc.

compatibility macros keep old code compiling

John Cupitt 0c35f461dc add "deprecated" flag to vips arguments 
deprecated arguments still work, but are not shown in help, nor are they
checked for "have-been-set"

you can tag required and optional args as deprecated ... obviously if
you deprecate a required argument you must replace it with a new
argument or scripts will break
 2012-08-07 12:52:50 +01:00
John Cupitt 643dc28950 turn on seq mode automatically in cli 
cli operations turn on seq mode automatically when they can

vips_operation_get_flags() added: lets you attach a set of flags to an
operation

flags for now are "nocache" (replacing the old nocache system) and "seqential"

if vips_object_set_argument_from_string() from string sees "seq" flag on the
object for which it is setting the arg, it enables sequential mode

all operations which can run sequentially have been tagged

the operation printer knows about flags and can display them
