Detailed Description

template<typename T, unsigned depth, unsigned alpha>
class Syndicate::Data::Block< T, depth, alpha >

It is a block of pixels. There are many way to pack the data that we can specify with templates parameters.

• The type T represent the number of pixels in the block. So for a uint8_t there are 8 pixels, for a uint32_t there are 32 pixels.
• The constant depth give the number of bits per pixels (without alpha channel).
• The constant alpha can be 0 or 1 and tell if there is an alpha channel.

If there is an alpha channel the data are packed like this : | alpha | bit0 | bit1 | bit2 | bit3 |

template<typename TColors>

void Syndicate::Data::Block< T, depth, alpha >::pixel	(	unsigned	i,
		TColors *	pix,
		const TColors *	colors = Colors< TColors >::_default
	)			const [inline]

Fill the pixel byte with the color of the ith pixel of this block.

Parameters:

[in]	i	the index of the pixel in the range [0;_width]
[out]	pix	the pointer to the byte where the color must be wrote
