| pngdebug.h |
Define PNG_DEBUG at compile time for debugging information. Higher
numbers for PNG_DEBUG mean more debugging information. This has
only been added since version 0.95 so it is not implemented throughout
libpng yet, but more support will be added as needed.
png_debug[1-2]?(level, message ,arg{0-2})
Expands to a statement (either a simple expression or a compound
do..while(0) statement) that outputs a message with parameter
substitution if PNG_DEBUG is defined to 2 or more. If PNG_DEBUG
is undefined, 0 or 1 every png_debug expands to a simple expression
(actually ((void)0)).
level: level of detail of message, starting at 0. A level 'n'
message is preceded by 'n' 3-space indentations (not implemented
on Microsoft compilers unless PNG_DEBUG_FILE is also
defined, to allow debug DLL compilation with no standard IO).
message: a printf(3) style text string. A trailing '\n' is added
to the message.
arg: 0 to 2 arguments for printf(3) style substitution in message.

png_handle_PLTE() may have canceled a valid tRNS chunk but left the
'valid' flag for the detection of duplicate chunks. Do not report a
valid tRNS chunk in this case.

| pnginfo.h |
png_info is a structure that holds the information in a PNG file so
that the application can find out the characteristics of the image.
If you are reading the file, this structure will tell you what is
in the PNG file. If you are writing the file, fill in the information
you want to put into the PNG file, using png_set_*() functions, then
call png_write_info().
The names chosen should be very close to the PNG specification, so
consult that document for information about the meaning of each field.
With libpng < 0.95, it was only possible to directly set and read the
the values in the png_info_struct, which meant that the contents and
order of the values had to remain fixed. With libpng 0.95 and later,
however, there are now functions that abstract the contents of
png_info_struct from the application, so this makes it easier to use
libpng with dynamic libraries, and even makes it possible to use
libraries that don't have all of the libpng ancillary chunk-handing
functionality. In libpng-1.5.0 this was moved into a separate private
file that is not visible to applications.
The following members may have allocated storage attached that should be
cleaned up before the structure is discarded: palette, trans, text,
pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
splt_palettes, scal_unit, row_pointers, and unknowns. By default, these
are automatically freed when the info structure is deallocated, if they were
allocated internally by libpng. This behavior can be changed by means
of the png_data_freer() function.
More allocation details: all the chunk-reading functions that
change these members go through the corresponding png_set_*
functions. A function to clear these members is available: see
png_free_data(). The png_set_* functions do not depend on being
able to point info structure members to any of the storage they are
passed (they make their own copies), EXCEPT that the png_set_text
functions use the same storage passed to them in the text_ptr or
itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
functions do not make their own copies.

| pngpriv.h |
The symbols declared in this file (including the functions declared
as extern) are PRIVATE. They are not part of the libpng public
interface, and are not recommended for use by regular applications.
Some of them may become public in the future; others may stay private,
change in an incompatible way, or even disappear.
Although the libpng users are not forbidden to include this header,
they should be well aware of the issues that may arise from doing so.

| pngread.c |
Create a PNG structure for reading, and allocate any memory needed. |
141658 |
| pngrio.c |
Read the data from whatever input you are using. The default routine
reads from a file pointer. Note that this routine sometimes gets called
with very small lengths, so you should implement some kind of simple
buffering if you are using unbuffered reads. This should never be asked
to read more than 64K on a 16-bit machine.

| pngrtran.c |
Set the action on getting a CRC error for an ancillary or critical chunk. |

| pngrutil.c |
The minimum 'zlib' stream is assumed to be just the 2 byte header, 5 bytes
minimum 'deflate' stream, and the 4 byte checksum.

| pngstruct.h |
The structure that holds the information to read and write PNG files.
The only people who need to care about what is inside of this are the
people who will be modifying the library for their own special needs.
It should NOT be accessed directly by an application.

| pngwio.c |
Write the data to whatever output you are using. The default routine
writes to a file pointer. Note that this routine sometimes gets called
with very small lengths, so you should implement some kind of simple
buffering if you are using unbuffered writes. This should never be asked
to write more than 64K on a 16-bit machine.

Pack pixels into bytes. Pass the true bit depth in bit_depth. The
row_info bit depth should be 8 (one pixel per byte). The channels
should be 1 (this only happens on grayscale and paletted images).
