-.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
-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).
-
-The following code can be used to prevent an application from using the
-thread_unsafe features, even if libpng was built with PNG_THREAD_UNSAFE_OK
-defined:
-
-#if defined(PNG_USE_PNGGCCRD) && defined(PNG_ASSEMBLER_CODE_SUPPORTED) \
-  && defined(PNG_THREAD_UNSAFE_OK)
-    /* Disable thread-unsafe features of pnggccrd */
-    if (png_access_version() >= 10200)
-    {
-      png_uint_32 mmx_disable_mask = 0;
-      png_uint_32 asm_flags;
-
-      mmx_disable_mask |= ( PNG_ASM_FLAG_MMX_READ_COMBINE_ROW  \
-                          | PNG_ASM_FLAG_MMX_READ_FILTER_SUB   \
-                          | PNG_ASM_FLAG_MMX_READ_FILTER_AVG   \
-                          | PNG_ASM_FLAG_MMX_READ_FILTER_PAETH );

+%-%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_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).
+%-%
+%-%The following code can be used to prevent an application from using the
+%-%thread_unsafe features, even if libpng was built with PNG_THREAD_UNSAFE_OK
+%-%defined:
+%-%

+Width and height limits
+
+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.
+Since very few applications really need to process such large images,
+we have imposed an arbitrary 1-million limit on rows and columns.
+Larger images will be rejected immediately with a png_error() call. If
+you wish to override this limit, you can use
+
+   png_set_user_limits(png_ptr, width_max, height_max);
+
+to set your own limits, or use width_max = height_max = 0x7fffffffL
+to allow all valid dimensions (libpng may reject some very large images
+anyway because of potential buffer overflow conditions).
+
+You should put this statement after you create the PNG structure and
+before calling png_read_info(), png_read_png(), or png_process_data().
+If you need to retrieve the limits that are being applied, use
+
+   width_max = png_get_user_width_max(png_ptr);

-* The zlib source files are in ..\..\..\zlib
-* The zlib project files are in ..\..\..\zlib\projects\visualc6
-
-
-To use:
-
-1) On the main menu, select "File | Open Workspace".
-   Open "libpng.dsw".
-
-2) Select "Build | Set Active Configuration".
-   Choose the configuration you wish to build.
-   (Choose libpng or pngtest; zlib will be built automatically.)
-
-3) Select "Build | Clean".
-
-4) Select "Build | Build ... (F7)".  Ignore warning messages about
-   not being able to find certain include files (e.g. alloc.h).
-
-5) If you built the sample program (pngtest),

-This project builds the libpng binaries as follows:
-
-* Win32_DLL_Release\libpng13.dll      DLL build
-* Win32_DLL_Debug\libpng13d.dll       DLL build (debug version)
-* Win32_DLL_ASM_Release\libpng13.dll  DLL build using ASM code
-* Win32_DLL_ASM_Debug\libpng13d.dll   DLL build using ASM (debug version)
-* Win32_DLL_VB\libpng13vb.dll         DLL build for Visual Basic, using stdcall
-* Win32_LIB_Release\libpng.lib        static build

-
-Notes:
-
-If you change anything in the source files, or select different compiler
-settings, please change the DLL name to something different than any of
-the above names.
-
-Also, make sure that DLLFNAME_POSTFIX and (PRIVATEBUILD or SPECIALBUILD)
-are defined when compiling the resource file.  DLLFNAME_POSTFIX contains
-the trailing letters that come after the version number.  PRIVATEBUILD
-and/or SPECIALBUILD store information describing the type of change made
-in the VERSIONINFO structure.  Please refer to MSDN for more information
-on the used macros and the nature of their content.  For an example on
-how to define these macros, look at the resource compiler settings for
-the "Win32 DLL VB" configuration.
-
-All DLLs built by this project use the Microsoft dynamic C runtime library
-MSVCRT.DLL (MSVCRTD.DLL for debug versions).  If you distribute any of the
-above mentioned libraries you should also include this DLL in your package.
