VIPS changed from 7.10 to 7.12 (not exhaustive, see ChangeLog for details) Non-backwards compatible changes ================================ - IMAGE->Hist is deprecated, use im_history_get() instead - im_append_Hist() removed - IMAGE->Bbits is deprecated (now ignored) - im_region_local() replaced by im_region_buffer() VIPS enhancements ================= - new backwards and forwards compatible VIPS file format: it has a new metadata system that efficiently shares and propogates ICC profiles, EXIF data, etc. & whatever - speed ups: new pixel buffer cache saves and reuses computations, uses liboil where possible for a small speedup - SMP scaling: simplified lock system improves SMP scaling, double-buffered image writes overlap computation - lower mem use: new mmap window cache shares file mappings, history buffers share and reuse image history metadata - built-in support for new image formats: OpenEXR, Analyze7, CSV - RGB16 and GREY16 image hints - uses GOption for much better command-line argument handling - better C++ binding: namespaces, VError derives from std::exception, image and number vector constants - python binding - gcc sentinel attributes added - added GValue as an arg type - added im_benchmark() and friends for testing - new functions: im_analyze2vips(), im_benchmark*(), im_buildlut(), im_concurrency_get/set(), im_contrast_surface(), im_contrast_surface_raw(), im_copy_from(), im_copy_morph(), im_cp_desc_array(), im_cp_descv(), im_extract_areabands(), im_flood_blob_copy(), im_get_option_group(), im_grid(), im_header_exists(), im_header_map(), im_history_get(), im_invalidate(), im_isscalar(), im_lineset(), im_linreg(), im_meta*(), im_msb(), im_norm_dmask(), im_project(), im_raw2vips(), IM_REGION_ADDR_TOPLEFT(), im_tile_cache(), im_video_test() VIPS changed from 7.8 to 7.10 (not exhaustive, see ChangeLog for details) Non-backwards compatible changes ================================ - no longer generates vips-config script, instead it makes .pc files for pkg-config ... replace any "vips-config" with "pkg-config vips-7.10" - origin hint semantics changed ... it now records the position in the output image of the origin of the input image - all float to int casts on pixel values are now floor() rather than rint(), for consistency with C casting semantics VIPS enhancements ================= - nip reworked for gtk+-2.4, now called nip2 - now based on glib, so VIPS no longer has it's own thread, plugin and data structure libraries - i18n support, although not quite complete yet - new error message API to make i18n possible (compatibility macros mean the old API still works) - new 'start up VIPS' call, im_init_world(), sets up i18n and threads (optional to call it, but i18n won't fully work unless you do) - C programs now just need "#include ", no other includes required - wraps the Pango font rendering library, see im_text() - new function flag: NOCACHE ... means the result of the call should not be cached, useful for video grab functions and paintbox functions - im_embed() now supports a wider range of embedding styles, including a fast edge stretch - all area operations use the new embed style to expand their input rather than their output, so there are no more black borders on filtered images - other new functions: im_render(), im_cache(), im_extract_bands(), im_copy_swap(), im_rint(), im_make_xy(), im_init_world(), im_error(), im_warn(), im_diag(), im_rank_image(), im_replicate() - many fixes and improvements to old funcs - configure and portability improvements Bug fixes ========= - all serious bug fixes got back-ported to 7.8, I think VIPS changes from 7.6 to 7.8 (again, not exhaustive, see ChangeLog for details) Non-backwards compatible changes ================================ - output format options specified in filenames: new prototypes for load and save tiff and jpeg - C++ API name changes ... error => VError - include path change - C includes - C++ includes - im_extract*() numbers bands from zero, not from 1 ... also other funcs which refer to bands (eg. im_lrmosaic() etc.) - mosaic funcs have extra max blend width parameter VIPS enhancements ================= - rewritten and much fancier ip (see separate docs), now called nip ... old ip (slightly fixed) still there - mmap windows remove 2GB image size limit - images have an origin hint field - icc transforms supported via wrapping of Little CMS - much, much faster Fourier transforms via wrapping of libfwfft - ppm/pgm/pbm read/write - C++ API enhancements: new constructors, more operator equivalences - new colourspace: Yxy - support for D50 colour temperature images - new functions: im_image(), im_system(), im_version*(), im_blend(), im_copy_set(), im_flood_blob(), im_icc_*(), im_open_local_array(), im_header_*(), im_sign(), im_ceil(), im_floor(), im_remainderconst*(), im_print(), im_guess_prefix(), im_remosaic(), im_invertlut(), Yxy funcs, color temperature funcs, im_clip2fmt(), im_blend(), im_lab_morph(), im_histnorm(), im_histcum(), im_video_v4l(), im_LabS2Lab(), im_Lab2LabS() - new type: IMAGEVEC - header is much faster - ip/nip split to separate packages - better vips2dj - better cygwin support, mingw support too - Mac OS X and Windows build support - new set of sensible #define names, old names can be turned off with -DIM_NO_VIPS7_COMPAT - many configure improvements Bug fixes ========= - speed ups - fixes to implicit image format conversions - im_zoom() spots integer overflow - im_LabS2LabQ() rounding on a/b slightly broken for a/b == 0 - fixes to refcounting in C++ API - mask casts in C++ were broken VIPS Changes for 7.4 to 7.6 Non-backwards compatible changes ================================ - im_histplot() has new (and better) rules - im_andconst(), im_orconst() and im_eorconst() now take a double, not an unsigned char, as their constant argument type - im_global_balance_float() renamed as im_global_balancef() to be more consistent with other functions - im_global_balance_search() removed ... you can do this efficiently with an ip macro now - new parameter "gamma" to im_global_balance() and im_global_balancef() ... sets the gamma for the input device with which the images were captured, set to 1.0 for old behaviour - im_malloc() now returns void *, not char * Bug fixes ========= - tiny memory leak in im_list_remove() fixed - oops, the value for sRGB in the header was wrong, now 22 - missing function descriptor for im_rank_raw() - im_dECMC_fromLab() was broken - im_erode() and im_dilate() output incorrect error messages if mask elements were not one of 0, 128, 255 - im_rotate_*mask*() functions were not preserving scale and offset values Package enhancements ==================== The whole thing is now GPL, with GNU configure ip changes ========== - better display control bar - matrix operations now appear in the workspace - new UI elements: input options and toggles - better LUT optimisation --- arithmetic operations on UCHAR images should be much faster - new macro language --- same as old one, but faster and much more powerful - all standard menus rewritten in new macro language, much nicer! - batch operations with Group/Ungroup - now uses GDK for drawing in image windows, much better colour handling on 8/16-bit graphics cards - image repaint is now threaded for an about-linear speedup as you add more CPUs - many interface improvements and polishes VIPS enhancements ================= - VIPS now uses POSIX threads (7.4 used Solaris threads) and has been rejigged to provide a nice threading API to functions which call the library - im_open() now knows about LSB- and MSB- first VIPS images, and silently converts them to native order ... it also now ignores case when deciding what format to write - new parameter type IM_INPUT_REALVEC, a vector of doubles - new set of functions with vector constants: im_lintra_vec(), im_powtra_vec(), im_expntra_vec(), all relational (im_equal_vec(), im_notequal_vec(), etc.), all boolean (im_and_vec() etc.) - new flag for function descriptors: "IM_FN_PTOP" set for point-to-point functions ... makes ip use LUTs for operation - im_tiff2vips() now reads and writes 16-bit images, and knows about zip (deflate) compression - convenience functions im_extract_band() extracts a band from an image; im_extract_area() extracts an area - im_list_member() tests for list contains object - new functions im_write_*mask_name(), im_create_*maskv() _ new functions im_remainder() and im_profile() - fourier filtering, forward transform, reverse transform, make power spectrum all free memory more quickly, making them suitable for very large images - new functions im_isMSBfirst() and im_amiMSBfirst() test images and this processor for MSB first byte order - im_malloc() now prints low-on-memory warnings to stderr with im_warning() for easier bug catching - D65_X0 updated for latest recommedations, D60, D93, D55, D50, A, B, C added - minor fixes to the C++ interface to bring it in line with the newer ANSI standards - more and more comprehensive prototypes in "proto.h" to aid C++ (use of "const" etc.) -
