Detailed Description

Overlay of several gray-scale/uint16_t channels into one BGRA8 image.

Thread-safe.

Constructor & Destructor Documentation

scope::ScopeOverlay::ScopeOverlay	(	const uint32_t &	_lines = 0,
		const uint32_t &	_linewidth = 0
	)

overlay will be initialized with 0s

Parameters

[in]	_lines	initial y resolution
[in]	_linewidth	initial x resolution

Definition at line 11 of file ScopeOverlay.cpp.

Member Function Documentation

void scope::ScopeOverlay::Create ( ScopeMultiImageCPtr const  _multi, const std::vector< ColorProps > &  _color_props  )

virtual

Creates an overlay from a multi image with the specified color properties per channel.

Parameters

[in]	_multi	the multi image to create overlay from
[in]	_color_props	the vector with the ColorProps for each channel

Alternative incarnations I had tried out... ~ 230 ms for 1024x1024 uint32_t size = overlay.size(); for ( uint32_t i = 0 ; i < size ; i++ ) overlay[i] += U16ToBGRA8Histo(pixel->at(i), col, ll, ul);

~1000ms for 1024x1024 This is 4x slower than the simple for loop (why?) auto itch = chimage->GetDataBeginConst(); std::for_each(std::begin(overlay), std::end(overlay), [&](BGRA8Pixel& pix) { pix += U16ToBGRA8Histo(*itch++, col, ll, ul); } ); several seconds (why??? to much overhead???) concurrency::parallel_transform(std::begin(overlay), std::end(overlay), it, std::begin(overlay), [&](BGRA8Pixel& pix, const uint16_t& gray) { return pix + U16ToBGRA8Histo(gray, col, ll, ul); } );
