Add pngprefix.h file generated by libpng configure/make process (which we
don't run during wxWidgets build, so this is something that will need to be
redone manually whenever libpng is upgraded, the procedure for doing this is
documented in docs/tech/tn0025.txt) in order to use "wx_" prefix for all
libpng public symbols. This should avoid at least some problems due to the
conflicts between the built-in libpng and shared libpng loaded into the
process as GTK+ libraries dependency under Unix.
Also rename wx_png_{warning,error} to use upper case PNG for consistency with
wx_PNG_stream_{reader,writer} and to avoid conflict with png_{warning,error}()
which we now rename to have "wx_" prefix.
Closes #14157.

Changes since the last public release (1.6.1):
|
|
|
|
Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling.
|
|
Fixed incorrect warning of excess deflate data. End condition - the
|
|
warning would be produced if the end of the deflate stream wasn't read
|
|
in the last row. The warning is harmless.
|
|
Corrected the test on user transform changes on read. It was in the
|
|
png_set of the transform function, but that doesn't matter unless the
|
|
transform function changes the rowbuf size, and that is only valid if
|
|
transform_info is called.
|
|
Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c
|
|
(Flavio Medeiros).
|
|
Corrected length written to uncompressed iTXt chunks (Samuli Suominen).
|
|
Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length
|
|
written by libpng-1.6.0 and 1.6.1.
|
|
Disallow storing sRGB information when the sRGB is not supported.
|
|
Merge pngtest.c with libpng-1.7.0
