H A DCHANGES243 Added checks for rowbytes overflow, in case png_size_t is less than 32 bits.
247 Added png_buffered_memcpy() and png_buffered_memset(), apply them to rowbytes.
323 Fixed a bug in pngset.c, introduced in version 0.99c, that sets rowbytes
434 Fixed bugs in calculation of the length of rowbytes when adding alpha
1254 Replaced row_info->rowbytes with row_bytes in png_write_find_filter()
1312 Added ROWBYTES macro to calculate rowbytes without integer overflow.
H A Dlibpng.txt504 rowbytes = png_get_rowbytes(png_ptr, info_ptr);
505 rowbytes - number of bytes needed to hold a row
720 rowbytes, as some of the transformations could increase the space
1124 call. This is most useful to update the info structure's rowbytes
