The branch, master has been updated discards 10a52540db85b4635b27062dc42e5be14f760088 (commit) via 68bfb03b0e8eb136310c54be62f50802631fa428 (commit) This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (10a52540db85b4635b27062dc42e5be14f760088) N -- N -- N (68bfb03b0e8eb136310c54be62f50802631fa428) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B.

This commit adds and abstract I/O interface and converts all image loaders to use it. This is a big step towards better faster and nicer containers (i.e. tar, tar.bz2, tar, etc...). It also allows you to read images from memory or whatever else by implementing simple read() and seek() wrappers. It also updates loaders documentation, adds a few testcases and example for loading images from a memory buffer. BEWARE: The work is not finalized and only basically tested. The ZIP loader is a bit broken (seeking does not work correctly).

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project gfxprim.git. The branch, master has been updated via 10a52540db85b4635b27062dc42e5be14f760088 (commit) via 342537c6df7ca58ca4ac35d0b6f1dae16ef6746a (commit) via f36c5f6d8df50ad268711cc97c9bc369672b7fe8 (commit) from 40750bfe2c6ba222376f458bb80e8e48ecf93e52 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://repo.or.cz/w/gfxprim.git/commit/10a52540db85b4635b27062dc42e5be14f76… commit 10a52540db85b4635b27062dc42e5be14f760088 Author: Cyril Hrubis <metan(a)ucw.cz> Date: Sat Jan 4 00:55:28 2014 +0100 loaders: Add I/O abstraction and convert loaders. This commit adds and abstract I/O interface and converts all image loaders to use it. This is a big step towards better faster and nicer containers (i.e. tar, tar.bz2, tar, etc...). It also allows you to read images from memory or whatever else for what by implementing simple read() and seek() wrappers. It also updates loaders documentation, adds a few testcases and example for loading images from a memory buffer. BEWARE: The work is not finalized and only basically tested. The ZIP loader is a bit broken (seeking does not work correctly). (More tests and fixes will come soon) Signed-off-by: Cyril Hrubis <metan(a)ucw.cz> diff --git a/build/syms/Loaders_symbols.txt b/build/syms/Loaders_symbols.txt index e424e98..d2121fe 100644 --- a/build/syms/Loaders_symbols.txt +++ b/build/syms/Loaders_symbols.txt @@ -2,7 +2,6 @@ GP_FWrite GP_FRead GP_MatchJPG -GP_OpenJPG GP_ReadJPG GP_LoadJPG GP_SaveJPG @@ -10,7 +9,6 @@ GP_ReadJPGMetaData GP_LoadJPGMetaData GP_MatchPNG -GP_OpenPNG GP_ReadPNG GP_LoadPNG GP_ReadPNGMetaData @@ -18,45 +16,44 @@ GP_LoadPNGMetaData GP_SavePNG GP_MatchBMP -GP_OpenBMP GP_LoadBMP GP_ReadBMP GP_SaveBMP GP_MatchPSP -GP_OpenPSP GP_ReadPSP GP_LoadPSP GP_MatchGIF GP_LoadGIF GP_ReadGIF -GP_OpenGIF GP_MatchTIFF -GP_OpenTIFF GP_ReadTIFF GP_LoadTIFF GP_SaveTIFF -GP_SavePBM +GP_ReadPBM GP_LoadPBM +GP_SavePBM GP_MatchPBM -GP_SavePGM +GP_ReadPGM GP_LoadPGM +GP_SavePGM GP_MatchPGM -GP_SavePPM +GP_ReadPPM GP_LoadPPM +GP_SavePPM GP_MatchPPM +GP_ReadPNM GP_LoadPNM GP_SavePNM GP_MatchPNM GP_ReadJP2 -GP_OpenJP2 GP_LoadJP2 GP_MatchJP2 @@ -94,3 +91,10 @@ GP_OpenZip GP_LineConvertible GP_LineConvertGet + +GP_IOFile +GP_IOMem +GP_IOMark +GP_IOSize +GP_IOFill +GP_IOReadF diff --git a/demos/c_simple/Makefile b/demos/c_simple/Makefile index 2d91834..68fa14a 100644 --- a/demos/c_simple/Makefile +++ b/demos/c_simple/Makefile @@ -19,7 +19,7 @@ APPS=backend_example loaders_example loaders filters_symmetry gfx_koch input_example fileview linetest randomshapetest fonttest loaders_register blittest textaligntest sin_AA x11_windows debug_handler gaussian_noise byte_utils version pretty_print timers- zip_container backend_timers_example + zip_container backend_timers_example memory_io ifeq ($(HAVE_LIBSDL),yes) APPS+=SDL_glue @@ -57,6 +57,7 @@ blittest: LDLIBS+=$(LDLIBS_BACKENDS) $(LDLIBS_LOADERS) sin_AA: LDLIBS+=$(LDLIBS_BACKENDS) x11_windows: LDLIBS+=$(LDLIBS_BACKENDS) zip_container: LDLIBS+=$(LDLIBS_LOADERS) $(LDLIBS_BACKENDS) +memory_io: LDLIBS+=$(LDLIBS_BACKENDS) $(LDLIBS_LOADERS) include $(TOPDIR)/app.mk include $(TOPDIR)/post.mk diff --git a/demos/c_simple/memory_io.c b/demos/c_simple/memory_io.c new file mode 100644 index 0000000..873b27c --- /dev/null +++ b/demos/c_simple/memory_io.c @@ -0,0 +1,118 @@ +/***************************************************************************** + * This file is part of gfxprim library. * + * * + * Gfxprim is free software; you can redistribute it and/or * + * modify it under the terms of the GNU Lesser General Public * + * License as published by the Free Software Foundation; either * + * version 2.1 of the License, or (at your option) any later version. * + * * + * Gfxprim is distributed in the hope that it will be useful, * + * but WITHOUT ANY WARRANTY; without even the implied warranty of * + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Hi! > The size limitation issues are not currently that important. However > can spiv open a BigTiff file even if it is just 20K in size? > All the current viewers refuse to open a BigTiff file even if it very > small. > GFXprim uses libtiff and accordinlgy to libtiff web pages BigTiff support was merged in 4.0, so this much or less depends on libtiff version. On my Linux system libtiff is new enough (4.0.3) and spiv seems to show sample BigTiff images I've found just fine (not all of them though, there are still unsupported pixel types, etc. but I'm working on that...). PS: Please use 'reply to all' next time so that the mail gets to the mailing list too. -- Cyril Hrubis

Hello: Does Gfxprim handle BigTiff images;i.e., libtiff v4.x and greater? If so can spiv show BigTiff images? BigTiff allows tiff files to be up to 2 to power of 64 minus one in size. regards, west suhanic
