The PNG specification allows the width and height of an image to be as

large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns.

.SH VI. Runtime optimization
|
||||
|
||||
A new feature in libpng 1.2.0 is the ability to dynamically switch between
|
||||
standard and optimized versions of some routines. Currently these are
|
||||
limited to three computationally intensive tasks when reading PNG files:
|
||||
decoding row filters, expanding interlacing, and combining interlaced or
|
||||
transparent row data with previous row data. Currently the optimized
|
||||
versions are available only for x86 (Intel, AMD, etc.) platforms with
|
||||
MMX support, though this may change in future versions. (For example,
|
||||
the non-MMX assembler optimizations for zlib might become similarly
|
||||
runtime-selectable in future releases, in which case libpng could be
|
||||
extended to support them. Alternatively, the compile-time choice of
|
||||
floating-point versus integer routines for gamma correction might become
|
||||
runtime-selectable.)
|
||||
|
||||
Because such optimizations tend to be very platform- and compiler-dependent,
|
||||
both in how they are written and in how they perform, the new runtime code
|
||||
in libpng has been written to allow programs to query, enable, and disable
|
||||
either specific optimizations or all such optimizations. For example, to
|
||||
enable all possible optimizations (bearing in mind that some "optimizations"
|
||||
may actually run more slowly in rare cases):
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
png_uint_32 mask, flags;
|
||||
|
||||
flags = png_get_asm_flags(png_ptr);
|
||||
mask = png_get_asm_flagmask(PNG_SELECT_READ | PNG_SELECT_WRITE);
|
||||
png_set_asm_flags(png_ptr, flags | mask);
|
||||
#endif
|
||||
|
||||
To enable only optimizations relevant to reading PNGs, use PNG_SELECT_READ
|
||||
by itself when calling png_get_asm_flagmask(); similarly for optimizing
|
||||
only writing. To disable all optimizations:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
flags = png_get_asm_flags(png_ptr);
|
||||
mask = png_get_asm_flagmask(PNG_SELECT_READ | PNG_SELECT_WRITE);
|
||||
png_set_asm_flags(png_ptr, flags & ~mask);
|
||||
#endif
|
||||
|
||||
To enable or disable only MMX-related features, use png_get_mmx_flagmask()
|
||||
in place of png_get_asm_flagmask(). The mmx version takes one additional
|
||||
parameter:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
int selection = PNG_SELECT_READ | PNG_SELECT_WRITE;
|
||||
int compilerID;
|
||||
|
||||
mask = png_get_mmx_flagmask(selection, &compilerID);
|
||||
#endif
|
||||
|
||||
On return, compilerID will indicate which version of the MMX assembler
|
||||
optimizations was compiled. Currently two flavors exist: Microsoft
|
||||
Visual C++ (compilerID == 1) and GNU C (a.k.a. gcc/gas, compilerID == 2).
|
||||
On non-x86 platforms or on systems compiled without MMX optimizations, a
|
||||
value of -1 is used.
|
||||
|
||||
Note that both png_get_asm_flagmask() and png_get_mmx_flagmask() return
|
||||
all valid, settable optimization bits for the version of the library that's
|
||||
currently in use. In the case of shared (dynamically linked) libraries,
|
||||
this may include optimizations that did not exist at the time the code was
|
||||
written and compiled. It is also possible, of course, to enable only known,
|
||||
specific optimizations; for example:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
flags = PNG_ASM_FLAG_MMX_READ_COMBINE_ROW \
|
||||
| PNG_ASM_FLAG_MMX_READ_INTERLACE \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_SUB \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_UP \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_AVG \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_PAETH ;
|
||||
png_set_asm_flags(png_ptr, flags);
|
||||
#endif
|
||||
|
||||
This method would enable only the MMX read-optimizations available at the
|
||||
time of libpng 1.2.0's release, regardless of whether a later version of
|
||||
the DLL were actually being used. (Also note that these functions did not
|
||||
exist in versions older than 1.2.0, so any attempt to run a dynamically
|
||||
linked app on such an older version would fail.)
|
||||
|
||||
To determine whether the processor supports MMX instructions at all, use
|
||||
the png_mmx_support() function:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
mmxsupport = png_mmx_support();
|
||||
#endif
|
||||
|
||||
It returns -1 if MMX support is not compiled into libpng, 0 if MMX code
|
||||
is compiled but MMX is not supported by the processor, or 1 if MMX support

VI. Runtime optimization
|
||||
|
||||
A new feature in libpng 1.2.0 is the ability to dynamically switch between
|
||||
standard and optimized versions of some routines. Currently these are
|
||||
limited to three computationally intensive tasks when reading PNG files:
|
||||
decoding row filters, expanding interlacing, and combining interlaced or
|
||||
transparent row data with previous row data. Currently the optimized
|
||||
versions are available only for x86 (Intel, AMD, etc.) platforms with
|
||||
MMX support, though this may change in future versions. (For example,
|
||||
the non-MMX assembler optimizations for zlib might become similarly
|
||||
runtime-selectable in future releases, in which case libpng could be
|
||||
extended to support them. Alternatively, the compile-time choice of
|
||||
floating-point versus integer routines for gamma correction might become
|
||||
runtime-selectable.)
|
||||
|
||||
Because such optimizations tend to be very platform- and compiler-dependent,
|
||||
both in how they are written and in how they perform, the new runtime code
|
||||
in libpng has been written to allow programs to query, enable, and disable
|
||||
either specific optimizations or all such optimizations. For example, to
|
||||
enable all possible optimizations (bearing in mind that some "optimizations"
|
||||
may actually run more slowly in rare cases):
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
png_uint_32 mask, flags;
|
||||
|
||||
flags = png_get_asm_flags(png_ptr);
|
||||
mask = png_get_asm_flagmask(PNG_SELECT_READ | PNG_SELECT_WRITE);
|
||||
png_set_asm_flags(png_ptr, flags | mask);
|
||||
#endif
|
||||
|
||||
To enable only optimizations relevant to reading PNGs, use PNG_SELECT_READ
|
||||
by itself when calling png_get_asm_flagmask(); similarly for optimizing
|
||||
only writing. To disable all optimizations:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
flags = png_get_asm_flags(png_ptr);
|
||||
mask = png_get_asm_flagmask(PNG_SELECT_READ | PNG_SELECT_WRITE);
|
||||
png_set_asm_flags(png_ptr, flags & ~mask);
|
||||
#endif
|
||||
|
||||
To enable or disable only MMX-related features, use png_get_mmx_flagmask()
|
||||
in place of png_get_asm_flagmask(). The mmx version takes one additional
|
||||
parameter:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
int selection = PNG_SELECT_READ | PNG_SELECT_WRITE;
|
||||
int compilerID;
|
||||
|
||||
mask = png_get_mmx_flagmask(selection, &compilerID);
|
||||
#endif
|
||||
|
||||
On return, compilerID will indicate which version of the MMX assembler
|
||||
optimizations was compiled. Currently two flavors exist: Microsoft
|
||||
Visual C++ (compilerID == 1) and GNU C (a.k.a. gcc/gas, compilerID == 2).
|
||||
On non-x86 platforms or on systems compiled without MMX optimizations, a
|
||||
value of -1 is used.
|
||||
|
||||
Note that both png_get_asm_flagmask() and png_get_mmx_flagmask() return
|
||||
all valid, settable optimization bits for the version of the library that's
|
||||
currently in use. In the case of shared (dynamically linked) libraries,
|
||||
this may include optimizations that did not exist at the time the code was
|
||||
written and compiled. It is also possible, of course, to enable only known,
|
||||
specific optimizations; for example:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
flags = PNG_ASM_FLAG_MMX_READ_COMBINE_ROW \
|
||||
| PNG_ASM_FLAG_MMX_READ_INTERLACE \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_SUB \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_UP \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_AVG \
|
||||
| PNG_ASM_FLAG_MMX_READ_FILTER_PAETH ;
|
||||
png_set_asm_flags(png_ptr, flags);
|
||||
#endif
|
||||
|
||||
This method would enable only the MMX read-optimizations available at the
|
||||
time of libpng 1.2.0's release, regardless of whether a later version of
|
||||
the DLL were actually being used. (Also note that these functions did not
|
||||
exist in versions older than 1.2.0, so any attempt to run a dynamically
|
||||
linked app on such an older version would fail.)
|
||||
|
||||
To determine whether the processor supports MMX instructions at all, use
|
||||
the png_mmx_support() function:
|
||||
|
||||
#if defined(PNG_LIBPNG_VER) && (PNG_LIBPNG_VER >= 10200)
|
||||
mmxsupport = png_mmx_support();
|
||||
#endif
|
||||
|
||||
It returns -1 if MMX support is not compiled into libpng, 0 if MMX code
|
||||
is compiled but MMX is not supported by the processor, or 1 if MMX support
|
||||
is fully available. Note that png_mmx_support(), png_get_mmx_flagmask(),
|
||||
and png_get_asm_flagmask() all may be called without allocating and ini-
|
||||
tializing any PNG structures (for example, as part of a usage screen or
|
||||
"about" box).

||||

||||
