Detailed Description

Performs interpolation between a pixel's colors and it's neighbors.

Handles 32bpp and 8bpp source images transparently.

Inline interpolation

InlineInterpolate::InlineInterpolate	(	QImage *	image,
		unsigned int	background
	)			`[inline]`

Constructs an interpolation object.

Do this outside your main loop then call the inline interpolate methods when you need them.

Parameters:

	image	The image whose pixels you will be interpolating. Once you have created an interpolation object you can change the image's pixel data, but do not resize or reset it.
	background	The background color to use if a pixel's neighbor is off the edge of the image.

Definition at line 54 of file interpolate.h.

unsigned int InlineInterpolate::interpolate	(	float	x_offset,
		float	y_offset
	)			`[inline]`

Interpolates the pixel at the given x,y position.

If the pixel's neighbor is off the edge of the image the last pixel is extended.

Definition at line 79 of file interpolate.h.

unsigned int InlineInterpolate::interpolateBackground	(	float	x_offset,
		float	y_offset
	)			`[inline]`

Interpolates the pixel at the given x,y position.

If the pixel's neighbor is off the edge of the image the background color is used.
