Pixel Format Description

ADTF comes with some predefined image formats using a generic pixel description. Usually most image formats can be described channel based.

There are 2 channelbased pixelformats provided:

par_rgba RGB(A) Pixels

R - Red channel
G - Green channel
B - Blue channel
A - Alpha channel

par_grey Grey Pixels

GREY - Grey channel

There channel (bit)size and position within a pixel is described generic. For a 8 Bit grey pixel "GREY(8)" is used, where "GREY" is the channel and the followed "(8)" describes its size.

A RGB pixel value is described i.e. via "R(8)G(8)B(8)(8)". "R" has 8 Bits followed by "G" and "B". The trailing empty channel is to fulfill a 32 Bit pixel size at a whole. The whole pixel size is a sum out of each "(\<bitsize\>)" pattern.

Generic access

The ADTF Streaming SDK comes with some functionality to calculate a Pixel Format Description. Consider the following:

stream_image_format_is_generic_greyscale
stream_image_format_is_generic_rgb
stream_image_format_is_generic
stream_image_format_get_generic_pixel_size
stream_image_format_get_generic_mask
