; The following are examples of calls to png_set_alpha_mode to achieve the
; required overall gamma correction and, where necessary, alpha
; premultiplication.
; png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
; This is the default libpng handling of the alpha channel - it is not
; pre-multiplied into the color components. In addition the call states
; that the output is for a sRGB system and causes all PNG files without gAMA
; chunks to be assumed to be encoded using sRGB.
; png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
; In this case the output is assumed to be something like an sRGB conformant
; display preceeded by a power-law lookup table of power 1.45. This is how
; early Mac systems behaved.
; png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_GAMMA_LINEAR);
; This is the classic Jim Blinn approach and will work in academic
; environments where everything is done by the book. It has the shortcoming
; of assuming that input PNG data with no gamma information is linear - this
; is unlikely to be correct unless the PNG files where generated locally.
; Most of the time the output precision will be so low as to show
; significant banding in dark areas of the image.
; png_set_expand_16(pp);
; png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
; This is a somewhat more realistic Jim Blinn inspired approach. PNG files
; are assumed to have the sRGB encoding if not marked with a gamma value and
; the output is always 16 bits per component. This permits accurate scaling
; and processing of the data. If you know that your input PNG files were
; generated locally you might need to replace PNG_DEFAULT_sRGB with the
; correct value for your system.
; png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
; If you just need to composite the PNG image onto an existing background
; and if you control the code that does this you can use the optimization
; setting. In this case you just copy completely opaque pixels to the
; output. For pixels that are not completely transparent (you just skip
; those) you do the composition math using png_composite or png_composite_16
; below then encode the resultant 8-bit or 16-bit values to match the output
; encoding.
; Other cases
; If neither the PNG nor the standard linear encoding work for you because
; of the software or hardware you use then you have a big problem. The PNG
; case will probably result in halos around the image. The linear encoding
; will probably result in a washed out, too bright, image (it's actually too
; contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
; substantially reduce the halos. Alternatively try:
; png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
; This option will also reduce the halos, but there will be slight dark
; halos round the opaque parts of the image where the background is light.
; In the OPTIMIZED mode the halos will be light halos where the background
; is dark. Take your pick - the halos are unavoidable unless you can get
; your hardware/software fixed! (The OPTIMIZED approach is slightly
; faster.)
; When the default gamma of PNG files doesn't match the output gamma.
; If you have PNG files with no gamma information png_set_alpha_mode allows
; you to provide a default gamma, but it also sets the ouput gamma to the
; matching value. If you know your PNG files have a gamma that doesn't
; match the output you can take advantage of the fact that
; png_set_alpha_mode always sets the output gamma but only sets the PNG
; default if it is not already set:
; png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
; png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
; The first call sets both the default and the output gamma values, the
; second call overrides the output gamma without changing the default. This
; is easier than achieving the same effect with png_set_gamma. You must use
; PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
; fire if more than one call to png_set_alpha_mode and png_set_background is
; made in the same read operation, however multiple calls with PNG_ALPHA_PNG
; are ignored.
