+ * just converting them all to 32-bit RGBA PNG files; you can do that between
+ * the call to png_image_finish_read and png_image_write_to_file.  You can also
+ * ask for the image data to be presented in a number of different formats.  You
+ * do this by simply changing the 'format' parameter set before allocating the
+ * buffer.
+ *
+ * The format parameter consists of five flags that define various aspects of
+ * the image, you can simply add these together to get the format or you can use
+ * one of the predefined macros from png.h (as above):
+ *
+ * PNG_FORMAT_FLAG_COLOR: if set the image will have three color components per
+ *    pixel (red, green and blue), if not set the image will just have one
+ *    luminance (grayscale) component.
+ *
+ * PNG_FORMAT_FLAG_ALPHA: if set each pixel in the image will have an additional
+ *    alpha value; a linear value that describes the degree the image pixel
+ *    covers (overwrites) the contents of the existing pixel on the display.
+ *
+ * PNG_FORMAT_FLAG_LINEAR: if set the components of each pixel will be returned
+ *    as a series of 16-bit linear values, if not set the components will be
+ *    returned as a series of 8-bit values encoded according to the 'sRGB'
+ *    standard.  The 8-bit format is the normal format for images intended for
+ *    direct display, because almost all display devices do the inverse of the
+ *    sRGB transformation to the data they receive.  The 16-bit format is more
+ *    common for scientific data and image data that must be further processed;
+ *    because it is linear simple math can be done on the component values.
+ *    Regardless of the setting of this flag the alpha channel is always linear,
+ *    although it will be 8 bits or 16 bits wide as specified by the flag.
+ *
+ * PNG_FORMAT_FLAG_BGR: if set the components of a color pixel will be returned
+ *    in the order blue, then green, then red.  If not set the pixel components
+ *    are in the order red, then green, then blue.
+ *
+ * PNG_FORMAT_FLAG_AFIRST: if set the alpha channel (if present) precedes the
+ *    color or grayscale components.  If not set the alpha channel follows the
+ *    components.
+ *
+ * You do not have to read directly from a file.  You can read from memory or,
+ * on systems that support it, from a <stdio.h> FILE*.  This is controlled by
+ * the particular png_image_read_from_ function you call at the start.  Likewise
+ * on write you can write to a FILE* if your system supports it.  Check the
+ * macro PNG_STDIO_SUPPORTED to see if stdio support has been included in your
+ * libpng build.
+ *
+ * If you read 16-bit (PNG_FORMAT_FLAG_LINEAR) data you may need to write it in
+ * the 8-bit format for display.  You do this by setting the convert_to_8bit
+ * flag to 'true'.
+ *
+ * Don't repeatedly convert between the 8-bit and 16-bit forms.  There is
+ * significant data loss when 16-bit data is converted to the 8-bit encoding and
+ * the current libpng implementation of convertion to 16-bit is also
+ * significantly lossy.  The latter will be fixed in the future, but the former
+ * is unavoidable - the 8-bit format just doesn't have enough resolution.
+ */
+
+/* If your program needs more information from the PNG data it reads, or if you
+ * need to do more complex transformations, or minimise transformations, on the
+ * data you read, then you must use one of the several lower level libpng
+ * interfaces.
+ *
+ * All these interfaces require that you do your own error handling - your
+ * program must be able to arrange for control to return to your own code any
+ * time libpng encounters a problem.  There are several ways to do this, but the
+ * standard way is to use the ANSI-C (C90) <setjmp.h> interface to establish a
+ * return point within your own code.  You must do this if you do not use the
+ * simplified interface (above).
+ *
+ * The first step is to include the header files you need, including the libpng
+ * header file.  Include any standard headers and feature test macros your
+ * program requires before including png.h:
+ */
