JPEG has defined four mode of operations, +summarized them as follows. + +(1) Sequential encoding: each image component is encoded in a single + left-to-right, top-to-bottom scan; +(2) Progressive encoding: the image is encoded in multiple scans for + applications in which transmission time is long, and the viewer + prefers to watch the image build up in multiple coarse-to-clear + passes; +(3) Lossless encoding: the images is encoded to guarantee exact recovery + of every source image sample value (even though the result is low + compression compared to the lossy modes); +(4) Hierarchical encoding: the image is encoded at multiple resolutions + so that lower-resolution versions may be accessed without first having + to decompress the image at its full resolution. + +Our lossless JPEG encoding program has an automatic prediction +selection value (PSV) selector which selects the best PSV among a +user provided or default set of PSVs. This selector guarantees the +best compression ratio for lossless JPEG. + +The encoding program "pnmtoljpg" compresses a Portable Pixmap or +Portable Graymap image to a lossles JPEG (ljpg) image using the +JPEG standard (DIS) lossless mode of operation. The decoding program +"ljpgtopnm" decodes a ljpg image to either a Portable Pixmap or +Portable Graymap image depending on the number of color components +stored in the ljpg image file. diff --git a/graphics/ljpeg/Makefile b/graphics/ljpeg/Makefile new file mode 100644 index 00000000000..5261288dadf --- /dev/null +++ b/graphics/ljpeg/Makefile @@ -0,0 +1,27 @@ +# $NetBSD: Makefile,v 1.1.1.1 2003/12/21 21:30:14 wiz Exp $ +# + +DISTNAME= ljpg +PKGNAME= ljpg-1.0 +WRKSRC= ${WRKDIR} +CATEGORIES= graphics +MASTER_SITES= ftp://ftp.cs.cornell.edu/pub/multimed/ +EXTRACT_SUFX= .tar.Z + +MAINTAINER= wiz@NetBSD.org +HOMEPAGE= ftp://ftp.cs.cornell.edu/pub/multimed/ +COMMENT= Lossless JPEG codec + +DIST_SUBDIR= ${PKGNAME_NOREV} + +USE_BUILDLINK2= yes +ALL_TARGET= default + +post-install: + ${INSTALL_DATA_DIR} ${PREFIX}/share/doc/ljpeg + ${INSTALL_DATA} ${WRKSRC}/Copyright ${PREFIX}/share/doc/ljpeg + ${INSTALL_DATA} ${WRKSRC}/README ${PREFIX}/share/doc/ljpeg + ${INSTALL_DATA_DIR} ${PREFIX}/share/examples/ljpeg + ${INSTALL_DATA} ${WRKSRC}/F-18* ${PREFIX}/share/examples/ljpeg + +.include "../../mk/bsd.pkg.mk" diff --git a/graphics/ljpeg/PLIST b/graphics/ljpeg/PLIST new file mode 100644 index 00000000000..563c177d642 --- /dev/null +++ b/graphics/ljpeg/PLIST @@ -0,0 +1,11 @@ +@comment $NetBSD: PLIST,v 1.1.1.1 2003/12/21 21:30:14 wiz Exp $ +bin/ljpgtopnm +bin/pnmtoljpg +man/man1/ljpgtopnm.1 +man/man1/pnmtoljpg.1 +share/doc/ljpeg/Copyright +share/doc/ljpeg/README +share/examples/ljpeg/F-18.ljpg +share/examples/ljpeg/F-18.ppm +@dirrm share/examples/ljpeg +@dirrm share/doc/ljpeg diff --git a/graphics/ljpeg/distinfo b/graphics/ljpeg/distinfo new file mode 100644 index 00000000000..5b428cdc486 --- /dev/null +++ b/graphics/ljpeg/distinfo @@ -0,0 +1,5 @@ +$NetBSD: distinfo,v 1.1.1.1 2003/12/21 21:30:14 wiz Exp $ + +SHA1 (ljpg-1.0/ljpg.tar.Z) = 47071fad1f11a3b9241a34b188ab07d54dcd13bc +Size (ljpg-1.0/ljpg.tar.Z) = 334459 bytes +SHA1 (patch-aa) = 562ce4a8f82c6ed59b4b730f59822d4749e925a3 diff --git a/graphics/ljpeg/patches/patch-aa b/graphics/ljpeg/patches/patch-aa new file mode 100644 index 00000000000..5f24f757e56 --- /dev/null +++ b/graphics/ljpeg/patches/patch-aa @@ -0,0 +1,43 @@ +$NetBSD: patch-aa,v 1.1.1.1 2003/12/21 21:30:14 wiz Exp $ + +--- Makefile.orig Wed Jun 22 18:48:40 1994 ++++ Makefile +@@ -1,19 +1,19 @@ + # + # Set BINDIR to where you want the binaries to go. + # +-BINDIR= /usr/public/sun4/bin ++BINDIR= ${PREFIX}/bin + + # + # Set MANDIR to where you want the man pages to go. + # +-MANDIR= /usr/public/share/man/man1 ++MANDIR= ${PREFIX}/man/man1 + + # + # Select your favorite compiler and compilation flags here. + # + #CC = cc +-CC = gcc +-CFLAGS= -I. -O2 ++#CC = gcc ++CFLAGS+= -I. + #CFLAGS= +O3 -I. + #CFLAGS= -O2 -DDEBUG + +@@ -36,12 +36,8 @@ ljpgtopnm: $(DECODE_OBJ) + $(CC) ${CFLAGS} -o $@ $(DECODE_OBJ) + + install: pnmtoljpg ljpgtopnm +- cp pnmtoljpg ljpgtopnm $(BINDIR) +- chmod 555 $(BINDIR)/pnmtoljpg +- chmod 555 $(BINDIR)/ljpgtopnm +- cp pnmtoljpg.1 ljpgtopnm.1 $(MANDIR) +- chmod 444 $(MANDIR)/pnmtoljpg.1 +- chmod 444 $(MANDIR)/ljpgtopnm.1 ++ ${BSD_INSTALL_PROGRAM} pnmtoljpg ljpgtopnm $(BINDIR) ++ ${BSD_INSTALL_MAN} pnmtoljpg.1 ljpgtopnm.1 $(MANDIR) + + clean: + rm -f core *.o pnmtoljpg ljpgtopnm |
