|
||||
the limit for PNG unsigned 32-bit integers when encoded.
|
||||
Revised calls to png_create_read_struct() and png_create_write_struct()
|
||||
for simpler debugging.

||||
Revised png_zalloc() so zlib handles errors (uses PNG_FLAG_MALLOC_NULL_MEM_OK)
|
||||
version 1.2.2beta2 [February 23, 2002]
|
||||
Check chunk_length and idat_size for invalid (over PNG_MAX_UINT) lengths.
|
||||
Check for invalid image dimensions in png_get_IHDR.
|
||||
Added missing "fi;" in the install target of the SGI makefiles.

||||
Removed unused png_write_destroy_info prototype from png.h
|
||||
Eliminated incorrect use of width_mmx from pnggccrd.c in pixel_bytes == 8 case

Added install-shared target to all makefiles that make shared libraries.
|
||||
Stopped a double free of palette, hist, and trans when not using free_me.
|
||||
Added makefile.32sunu for Sun Ultra 32 and makefile.64sunu for Sun Ultra 64.
|
||||
version 1.2.2beta4 [March 8, 2002]
|
||||
Compute background.gray and background_1.gray even when color_type is RGB
|
||||
in case image gets reduced to gray later (Jason Summers).
|
||||
Relocated a misplaced /bin/rm in the "install-shared" makefile targets
|
||||
Added PNG_1_0_X macro which can be used to build a 1.0.x-compatible library.
|
||||
version 1.2.2beta5 [March 26, 2002]
|
||||
Added missing PNGAPI to several function definitions.
|
||||
Check for invalid bit_depth or color_type in png_get_IHDR(), and
|
||||
check for missing PLTE or IHDR in png_push_read_chunk() (Matthias Clasen).

||||
Revised iTXt support to accept NULL for lang and lang_key.
|
||||
Compute gamma for color components of background even when color_type is gray.

||||
version 1.2.2beta6 [March 31, 2002]
|
||||
version 1.0.13beta1 [March 31, 2002]
|
||||
Prevent png_zalloc() from trying to memset memory that it failed to acquire.
|
||||
Add typecasts of PNG_MAX_UINT in pngset_cHRM_fixed() (Matt Holgate).
|
||||
Ensure that the right function (user or default) is used to free the
|
||||
png_struct after an error in png_create_read_struct_2().

||||
version 1.2.2rc1 [April 7, 2002]
|
||||
Save the ebx register in pnggccrd.c (Sami Farin)
|
||||
Add "mem_ptr = png_ptr->mem_ptr" in png_destroy_write_struct() (Paul Gardner).
