John Cupitt	d06c2fee22	use exif_tag_get_name_in_ifd() everywhere exif tag names change with the ids they appear in, so you must always use exif_tag_get_name_in_ifd(), not exif_tag_get_name() see: https://github.com/jcupitt/libvips/pull/1030	2018-07-09 09:35:39 +01:00

John Cupitt	0486218ff5	don't use Ping in magickload it's too unreliable :-( we are forced to read every time	2018-05-29 17:20:46 +01:00
John Cupitt	d251b37d92	add vips_argument_get_id() We had a global we incremented to allocate property ids, but of course that won't work with DLLs. Instead, add vips_argument_get_id() and call that to allocate new prop ids. See: https://github.com/jcupitt/libvips/issues/985	2018-05-29 16:49:20 +01:00

John Cupitt	73a55e0322	update ChangeLog	2018-05-25 16:06:05 +01:00
John Cupitt	b085908558	remove vips7 stuff from API You must now include vips7 support explicitly with #include <vips/vips7compat.h> in your code just after including `vips.h`. The old vips7 names, such as `Rect`, were starting to cause problems with other packages like opencv.	2018-05-16 15:08:21 +01:00

John Cupitt	e496df598b	working!	2018-05-01 15:50:48 +01:00
John Cupitt	4d683559aa	add a fontfile option to text use @fontfile to give a font to load ... note that this just loads the font, you'll need to set it with @font as well see https://github.com/jcupitt/libvips/issues/950	2018-04-26 21:03:40 +01:00
John Cupitt	da6f4fd043	add n-pages metadata item tiff, magick and pdf load now attach an n-pages metadata item recording the number of pages in the orginal file see https://github.com/jcupitt/libvips/issues/953	2018-04-26 08:55:31 +01:00
John Cupitt	4f22e8d1dc	add jpeg-chroma-subsample to jpegload The jpeg loader now sets the field jpeg-chroma-subsample to record chroma subsample. See https://github.com/jcupitt/libvips/issues/954	2018-04-25 16:04:20 +01:00
John Cupitt	c410dc2db8	add format option to magickload Some magick coders (eg. ICO) don't sniff the filetype from the data, so when you try to load from a string, imagemagick is unable to pick the right decode path. Add a @format option so callers can hint the filetype. see https://github.com/jcupitt/pyvips/issues/39	2018-04-24 15:06:52 +01:00
John Cupitt	c0569d25bf	final fixups - add buffer load - test under valgrind - code sharing with the poppler pdf loader	2018-04-11 18:53:38 +01:00

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. See https://github.com/lovell/sharp/issues/1185	2018-04-10 15:18:18 +01:00
John Cupitt	15abbbe986	set "interlaced" for jpg and png set "interlaced" for interlaced png and jpg images	2018-04-09 17:14:38 +01:00
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. see https://github.com/jcupitt/libvips/pull/930	2018-04-09 13:27:57 +01:00

John Cupitt	632bce3c78	reduce stack use for radsave fixes a crash on very low stack libcs like musl	2018-04-04 16:25:35 +01:00
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. See: https://github.com/jcupitt/libvips/issues/918	2018-04-03 14:36:43 +01:00
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.	2018-04-01 10:32:48 +01:00
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.	2018-03-22 12:08:39 +00:00

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. See https://github.com/jcupitt/libvips/issues/152	2018-03-08 13:11:54 +00:00

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.	2018-03-04 18:30:25 +00:00

John Cupitt	6f16a9df71	fix a crash with heavy use of draw we were leaving a few bits of the original image around after vips_image_copy_memory(), including the progress signal ... if earlier images were freed, perhaps by a GC in a language binding, we could get a dangling pointer thanks Nakilon, see https://github.com/jcupitt/ruby-vips/issues/140	2017-10-09 22:27:36 +01:00

John Cupitt	653e99ea82	don't build enumtypes so often we were only replacing enumtypes if it had changed, but this meant that make usually thought it was out of date compared to the source files, and rebuilt it, which needed perl now we always replace it, so (hopefully) perl is no longer a compile-time dependency	2017-08-30 14:37:48 +01:00

John Cupitt	e2c83fe4bd	fix jpegload fail we were only failing on libjpeg errors, but libjpeg treats very serious things thaht we want to be able to catch (like truncated files) as warnings ... we must therefore error out if fail is set and libjpeg issues a warning see https://github.com/lovell/sharp/issues/793	2017-08-29 09:49:38 +01:00

John Cupitt	47a763209a	hide warnings if VIPS_WARNING is defined If VIPS_WARNING is defined, suppress all warning messages from vips by installing a null log handler. Libraries should not call g_log_set_handler(), it is supposed to be for the application layer, but this can be awkward to set up if you are using libvips from something like Ruby. This env var hack is a workaround. see https://github.com/jcupitt/ruby-vips/issues/119 see https://github.com/jcupitt/libvips/issues/544	2017-08-04 18:01:19 +01:00

John Cupitt	9a1c3f9405	rename 'disc' as 'memory' the old 'disc' flag to open defaulted TRUE and disabled read via disc if you set it FALSE, which was very confusing replace it with a flag called 'memory' which defaults FALSE and forces read via memory if set TRUE 'disc' is still there and still works, it's just tagged as deprecated see https://github.com/jcupitt/libvips/issues/677	2017-07-07 09:45:49 +01:00

John Cupitt	7b64246af2	fix a couple of issues with huge profiles The base64 encode limit was 1MB, but some huge profiles can get over that, so it's now 10MB. transform_save_string_blob() was incorrectly setting a refstring not a blob as an error fallback, potentially leaving a dangling pointer.

John Cupitt	65105a9442	upsize with something other than nearest vips_resize() uses to just use nearest when upsizing, following standard practice in repro. This is often unfortunate for image processing, where small nearest upsizes will produce obvious aliasing. It now picks a VipsInterpolate which corresponds (roughly) to the selected VipsKernel and uses that with affine for any upsizing.	2016-06-22 10:33:08 +01:00
John Cupitt	11b136b2df	pyvips8 can create new metadata previously it tried to lookup the type of the field in set(), now if OK if there's no field there already	2016-06-17 11:27:13 +01:00
John Cupitt	f3326c8126	better vips_resize() for cubic/linear/nearest vips_resize() used to do most of a downsize with vips_shrink() and the final 200 - 300% with vips_reduce(). This was correct for lanczos2/3, but not right for linear/cubic, which need more shrink and less reduce to avoid aliasing. This patch makes vips_resize() leave the final 100 - 200% to vips_reduce() for linear/cubic, and leave everything to reduce for nearest.	2016-06-16 09:46:02 +01:00

John Cupitt	1909b31bd6	vips_image_write() only refs input when it has to when you write to a non-partial image, you create a sink ... so vips_image_write() only needs to ref the input when writing to partials this change makes it much easier to (for example) combine many images in bounded space, see for example: https://gist.github.com/jcupitt/c516325ebef7601b5da610af5619c9b2	2016-06-10 13:58:01 +01:00

John Cupitt	b90145ca31	free pixel buffers on image close We were freeing pixel buffers on thread exit. This was convenient, but meant that main thread buffers were not freed until program exit. As a result, long-running programs which created main thread buffers would slowly fill the operation cache with useless junk, forcing everything else out. This change also frees pixel buffers on image close. This makes the cache work much better in long-running programs, and can substantially reduce memory use. See https://github.com/jcupitt/libvips/issues/466	2016-06-06 13:50:25 +01:00

John Cupitt	2a77301033	free main-thread pixel buffers threads keep pixel buffers in thread-private storage, and free these buffers on thread exit ... this means buffers created by the main thread will only be freed on program exit! if your program creates any main-thread buffers, these buffers will eventually fill the operation cache and force everything else out, making the cache useless this patch explicitly frees main-thread pixel buffers on image close	2016-06-05 16:59:07 +01:00

John Cupitt	54d8e4808f	restore bandfmt after unpremultiply in thumbnail vips_unpremultiply() always outputs float. If you save the output of vipsthumbnail to a format that supports float files, like tiff, it won't ever get cast back to the source format. Example: $ vipsheader Opera-icon-high-res.png Opera-icon-high-res.png: 3056x3325 uchar, 4 bands, srgb, pngload $ vipsthumbnail Opera-icon-high-res.png -o x.tif $ vipsheader x.tif x.tif: 117x128 float, 4 bands, scrgb, tiffload This change makes it note and restore BandFmt aropund pre/unpremultiply.

John Cupitt	2ea5c5f7e5	make python bandrank() work like bandjoin() we had a custom wrapper for bandjoin(), but bandrank(), a function with an almost identical interface, did not ... this was confusing bandrank() now has a custom wrapper too ... this breaks API unfortunately, but hopefully very few people were using this thing and it's better to make this change as soon as possible	2016-03-01 12:12:51 +00:00
John Cupitt	25c3c49d1c	better handling of cast+shift for non-int formats before, im.cast(uchar, shift = true) where im was float and tagged as rgb16 would not shift the image, since it's unclear how much to shift a float type by now we do two casts: first, we guess the numeric range from the interpretation, so rgb16 would be ushort, so we cast float->ushort; second, we cast to the target type and do the shift on the way see https://github.com/jcupitt/libvips/issues/397 thanks apacheark	2016-03-01 11:31:54 +00:00

John Cupitt	01238a0fd5	more progressive jpg changes - Remove the nocache stuff for prog jpg images. There was no saving in practice, since operations downstream could be cached. nocache is for objects that can change, not for memory saving - Call _destroy on the decompress object much earlier, it frees a huge amount of memoey for prog jpg images.	2016-02-21 10:57:36 +00:00

John Cupitt	ef6d8f5979	make test for matlab files more specific Previously vips just called Mat_Open() to test if a file was a Matlab save file, but this is rather unreliable. For example, some JPEG files can crash libmatio, and it can incorrectly think that at least some JP2 files are Matlab save files. Instead, look for "MATLAB 5.0" at the start of the file. This is really too specific, the first 116 bytes of a Matlab save file are freeform text, but in practice all Matlab writers use the first few bytes to record the file type.

John Cupitt	3b32200cc1	sizealike() and friends elide completely sizealike() / formatalike() and bandsalike() used to just vips_copy() if the image didn't need any changes ... this was fast, but left a vips_copy_gen() in the pipeline, wasting a lot of space on the C stack during recursion. They now vanish completely if the image is already in the right format. Since we call them before most image processing operations, and often all three of them, this saves a lot of C stack, more than x2 even in simple cases. There might also be a measureable CPU saving if the operations are very simple (eg. insert).
