Historical notes
|
||||
----------------
|
||||
|
||||
The libpng library has been in extensive use and testing since mid-1995.
|
||||
Version 0.89, published a year later, was the first official release.
|
||||
By late 1997, it had finally gotten to the stage where there hadn't
|
||||
been significant changes to the API in some time, and people have a bad
|
||||
feeling about libraries with versions below 1.0. Version 1.0.0 was
|
||||
released in March 1998.
|
||||
|
||||
Note that some of the changes to the `png_info` structure render this
|
||||
version of the library binary incompatible with libpng-0.89 or
|
||||
earlier versions if you are using a shared library. The type of the
|
||||
"filler" parameter for png_set_filler() has changed from png_byte to
|
||||
png_uint_32, which will affect shared-library applications that use
|
||||
this function.
|
||||
`filler` parameter for `png_set_filler()` has changed from `png_byte`
|
||||
to `png_uint_32`, which will affect shared-library applications that
|
||||
use this function.
|
||||
|
||||
To avoid problems with changes to the internals of the png info_struct,
|
||||
To avoid problems with changes to the internals of the `info_struct`,
|
||||
new APIs have been made available in 0.95 to avoid direct application
|
||||
access to info_ptr. These functions are the png_set_<chunk> and
|
||||
png_get_<chunk> functions. These functions should be used when
|
||||
accessing/storing the info_struct data, rather than manipulating it
|
||||
access to `info_ptr`. These functions are the `png_set_<chunk>` and
|
||||
`png_get_<chunk>` functions. These functions should be used when
|
||||
accessing/storing the `info_struct` data, rather than manipulating it
|
||||
directly, to avoid such problems in the future.
|
||||
|
||||
It is important to note that the APIs did not make current programs
|
||||
that access the info struct directly incompatible with the new
|
||||
library, through libpng-1.2.x. In libpng-1.4.x, which was meant to
|
||||
be a transitional release, members of the png_struct and the
|
||||
info_struct can still be accessed, but the compiler will issue a
|
||||
be a transitional release, members of the `png_struct` and the
|
||||
`info_struct` can still be accessed, but the compiler will issue a
|
||||
warning about deprecated usage. Since libpng-1.5.0, direct access
|
||||
to these structs is not allowed, and the definitions of the structs
|
||||
reside in private pngstruct.h and pnginfo.h header files that are not
|
||||
accessible to applications. It is strongly suggested that new
|
||||
programs use the new APIs (as shown in example.c and pngtest.c), and
|
||||
older programs be converted to the new format, to facilitate upgrades
|
||||
in the future.
|
||||
****
|
||||
|
||||
Additions since 0.90 include the ability to compile libpng as a
|
||||
Windows DLL, and new APIs for accessing data in the info struct.
|
||||
Experimental functions include the ability to set weighting and cost
|
||||
factors for row filter selection, direct reads of integers from buffers
|
||||
on big-endian processors that support misaligned data access, faster
|

methods of doing alpha composition, and more accurate 16->8 bit color
