Branch: CURRENT, Version: 9d, Package name: jpeg-9d, Maintainer: pkgsrc-users

Independent JPEG Group's free JPEG software
-------------------------------------------

This package contains C software to implement JPEG image encoding, decoding,
and transcoding. JPEG is a standardized compression method for full-color
and gray-scale images.

The distributed programs provide conversion between JPEG "JFIF" format and
image files in PBMPLUS PPM/PGM, GIF, BMP, and Targa file formats. The
core compression and decompression library can easily be reused in other
programs, such as image viewers. The package is highly portable C code;
we have tested it on many machines ranging from PCs to Crays.

We are releasing this software for both noncommercial and commercial use.
Companies are welcome to use it as the basis for JPEG-related products.
We do not ask a royalty, although we do ask for an acknowledgement in
product literature (see the README file in the distribution for details).
We hope to make this software industrial-quality --- although, as with
anything that's free, we offer no warranty and accept no liability.

For more information, contact jpeg-info@uc.ag.

Log message:
all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

jpeg: Update to 9d

Changelog:
Version 9d  12-Jan-2020
-----------------------

Optimize the optimal Huffman code table generation to produce
slightly smaller files.  Thank to John Korejwa for suggestion.
Note: Requires rebuild of testimgp.jpg.

Decoding Huffman: Use default tables if tables are not defined.
Thank to Simone Azzalin for report (Motion JPEG),
and to Martin Strunz for hint.

Add sanity check in optimal Huffman code table generation.
Thank to Adam Farley for suggestion.

rdtarga.c: use read_byte(), with EOF check, instead of getc()
in read_*_pixel().
Thank to Chijin Zhou for cjpeg potential vulnerability report.

jmemnobs.c: respect the max_memory_to_use setting in
jpeg_mem_available() computation.  Thank to Sheng Shu and
Dongdong She for djpeg potential vulnerability report.

jdarith.c, jdhuff.c: avoid left shift of negative value
compiler warning in decode_mcu_AC_refine().
Thank to Indu Bhagat for suggestion.

Add x64 (64-bit) platform support, avoid compiler warnings.
Thank to Jonathan Potter, Feiyun Wang, and Sheng Shu for suggestion.

Adjust libjpeg version specification for pkg-config file.
Thank to Chen Chen for suggestion.

Restore GIF read and write support from libjpeg version 6a.
Thank to Wolfgang Werner (W.W.) Heinz for suggestion.

Improve consistency in raw (downsampled) image data processing mode.
Thank to Zhongyuan Zhou for hint.

Avoid out of bounds array read (AC derived table pointers)
in start pass in jdhuff.c.  Thank to Peng Li for report.

Improve code sanity (jdhuff.c).
Thank to Reza Mirzazade farkhani for reports.

Add jpegtran -drop option; add options to the crop extension and wipe
to fill the extra area with content from the source image region,
instead of gray out.

jpegtran: add an option to the -wipe switch to fill the region
with the average of adjacent blocks, instead of gray out.
Thank to Caitlyn Feddock and Maddie Ziegler for inspiration.

Make range extension bits adjustable (in jpegint.h).
Thank to Robin Watts for suggestion.

Provide macros for fflush() and ferror() in jinclude.h in order
to facilitate adaption by applications using an own FILE class.
Thank to Gerhard Huber for suggestion.

Add libjpeg pkg-config file.  Thank to Mark Lavi, Vincent Torri,
Patrick McMunn, and Huw Davies for suggestion.
