Changes since the last public release (1.6.9):
|
|
|
|
Version 1.6.10beta01 [February 9, 2014]
|
|
Backported changes from libpng-1.7.0beta30 and beta31:
|
|
Fixed a large number of instances where PNGCBAPI was omitted from
|
|
function definitions.
|
|
Added pngimage test program for png_read_png() and png_write_png()
|
|
with two new test scripts.
|
|
Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling
|
|
png_set_packing() in png_read_png().
|
|
Fixed combination of ~alpha with shift. On read invert alpha, processing
|
|
occurred after shift processing, which causes the final values to be
|
|
outside the range that should be produced by the shift. Reversing the
|
|
order on read makes the two transforms work together correctly and mirrors
|
|
the order used on write.
|
|
Do not read invalid sBIT chunks. Previously libpng only checked sBIT
|
|
values on write, so a malicious PNG writer could therefore cause
|
|
the read code to return an invalid sBIT chunk, which might lead to
|
|
application errors or crashes. Such chunks are now skipped (with
|
|
chunk_benign_error).
|
|
Make png_read_png() and png_write_png() prototypes in png.h depend
|
|
upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED.
|
|
Support builds with unsupported PNG_TRANSFORM_* values. All of the
|
|
PNG_TRANSFORM_* values are always defined in png.h and, because they
|
|
are used for both read and write in some cases, it is not reliable
|
|
to #if out ones that are totally unsupported. This change adds error
|
|
detection in png_read_image() and png_write_image() to do a
|
|
png_app_error() if the app requests something that cannot be done
|
|
and it adds corresponding code to pngimage.c to handle such options
|
|
by not attempting to test them.
|
|
|
|
Version 1.6.10beta02 [February 16, 2014]
|
|
Moved redefines of png_error(), png_warning(), png_chunk_error(),
|
|
and png_chunk_warning() from pngpriv.h to png.h to make them visible
|
|
to libpng-calling applications.
