| 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.

| pngget.c |
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 |
INTERNAL, PRIVATE definition of a PNG.
png_info is a modifiable description of a PNG datastream. The fields inside
this structure are accessed through png_get_<CHUNK>() functions and modified
using png_set_<CHUNK>() functions.
Some functions in libpng do directly access members of png_info. However,
this should be avoided. png_struct objects contain members which hold
caches, sometimes optimised, of the values from png_info objects, and
png_info is not passed to the functions which read and write image data.

| 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. |

- |
| 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 |
zlib.h defines the structure z_stream, an instance of which is included
in this structure and is required for decompressing the LZ compressed
data in PNG files.

| 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).
