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:

• RGB(A) Pixels
  • R - Red channel
  • G - Green channel
  • B - Blue channel
  • A - Alpha channel
• Grey Pixels
  • GREY - Grey channel

The 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.
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
