Detailed Description

A Camera coupled with one photo's ExifData.

This is the public face that callers care about. Callers shouldn't need to know whether a default color profile comes hard-coded or embedded in Exif. This class abstracts everything.

CameraData instances are lightweight. Shallow-copy them at will.

Constructor & Destructor Documentation

refinery::CameraData::CameraData	(	const Camera &	camera,
		const ExifData &	exifData
	)		[inline]

Creates a CameraData for a given photo.

The Camera and ExifData are both passed by reference and must exist for the lifetime of this CameraData.

Parameters:

[in]	camera	The static camera data.
[in]	exifData	The photograph's Exif data.

Definition at line 172 of file camera.h.

(

const CameraData &

rhs

)

[inline]

Copy constructor.

The Camera and ExifData are both passed by reference.

Parameters:

[in]

rhs

Original CameraData.

Here are some possible return values and what they represent:

 All RGB cameras use one of these Bayer grids:

 3 G R G R G R      3 B G B G B G      3 R G R G R G      3 G B G B G B

Returns:

The camera's sensor color pattern.

unsigned int refinery::CameraData::rawHeight

(

)

const

The height of the raw image, in pixels.

This is different from height(), which is the height of the output image. Some cameras capture margin pixels which have no value at all, and this height includes those.

Returns:

How many pixels are in each sensor column.

unsigned int refinery::CameraData::rawWidth

(

)

const

The width of the raw image, in pixels.

This is different from width(), which is the width of the output image. Some cameras capture margin pixels which have no value at all, and this width includes those.

Returns:

How many pixels are in each sensor row.
