bool IND_Image::Clear	(	byte	pR,
		byte	pG,
		byte	pB,
		byte	pA
	)

Parameters:

pR Byte R (Red)
pG Byte G (Green)
pB Byte B (Blue)
pA Byte A (Transparency)

Operation:

Clear the image to the chosen colour. Returns 0 if there is no image loaded.

bool IND_Image::GetPixel	(	int	pX,
		int	pY,
		byte *	pR,
		byte *	pG,
		byte *	pB,
		byte *	pA
	)

Parameters:

pX X coordenate.
pY Y coordanate.
pR Byte R (Red)
pG Byte G (Green)
pB Byte B (Blue)
pA Byte A (Transparency)

Operation:

Returns by reference the colour of the specified pixel (in RGBA). Returns 0 if there is no image loaded.

If the image format (see IND_Format) doesn't have alpha value (pA) this parameter can be omitted.

In the special case of IND_LUMINANCE type images, the pixel colour will be returned in pA.

bool IND_Image::PutPixel	(	int	pX,
		int	pY,
		byte	pR,
		byte	pG,
		byte	pB,
		byte	pA
	)

Parameters:

pX X coordenate.
pY Y coordanate.
pR Byte R (Red)
pG Byte G (Green)
pB Byte B (Blue)
pA Byte A (Transparency)

Operation:

Puts a pixel in the position and colour specified as parameters (in RGBA). Returns 0 if there is no image loaded.

If the image format (see IND_Format) doesn't have alpha value (pA) this parameter can be omitted.

In the special case of IND_LUMINANCE type images, the pixel colour must be specified in pA.

bool IND_Image::FlipH ( )

Parameters:

Operation:

Horizontal inversion. Returns 0 if there is no image loaded.

Original

Horizontal mirror

bool IND_Image::FlipV ( )

Parameters:

Operation:

Vertical inversion. Returns 0 if there is no image loaded.

Original

Vertical mirror

bool IND_Image::Convert ( IND_Format pFormat )

Parameters:

pFormat Format of the image. See IND_Format.

Operation:

Converts the image to the specified format. Returns 0 if there is no image loaded.

bool IND_Image::SetAlpha	(	byte	pR,
		byte	pG,
		byte	pB
	)

Parameters:

pR Byte R (Red)
pG Byte G (Green)
pB Byte B (Blue)

Operation:

Puts the alpha value of all pixels of the specified color into transparent. This is know as "color key". Returns 0 if there is no image loaded.

bool IND_Image::PasteImage	(	IND_Image *	pIm,
		int	pX,
		int	pY
	)

Parameters:

pIm Pointer to an image object
pX X Coordenate
pY Y Coordenate

Operation:

Pastes the image passed as parameter over the image that calls the method in the specified position. Returns 0 if there is no image loaded.

bool IND_Image::GaussianBlur ( int pIter )

Parameters:

pIter Iterations

Operation:

Applies a gaussian filter which intensity depends on the pIter parameter. Returns 0 if there is no image loaded.

Original

Gaussian blur

bool IND_Image::Contrast ( float pCont )

Parameters:

pCont Contrast

Operation:

Applies a contrast filter which intensity depends of the pCont parameter. Returns 0 if there is no image loaded.

Original

Contrast

bool IND_Image::Equalize ( )

Parameters:

Operation:

Applies a equalizator filter. Returns 0 if there is no image loaded.

Original

Equalizator

bool IND_Image::SetGamma ( float pGamma )

Parameters:

pGamma Gamma quality

Operation:

Applies a gamma filter which intensity depends on the pGamma parameter. Values lower than 1 makes the image darker, and values greater than 1 makes it clearer. Returns 0 if there is no image loaded.

Original

Gamma

bool IND_Image::Negative ( )

Parameters:

Operation:

Applies a negative filter. Returns 0 if there is no image loaded.

Original

Negative

bool IND_Image::Noisify ( float pNoise )

Parameters:

pNoise Noise quantity

Operation:

Applies a noise filter which intensity depends on the pNoise parameter. The greater this value is, the more noise is applied to the image. Returns 0 if there is no image loaded.

Original

Noise

bool IND_Image::Pixelize ( int pPixSize )

Parameters:

pPixSize Size of each pixel

Operation:

Applies a pixelation filter. The size of each pixel is specified by the parameter pPixSize. Returns 0 if there is no image loaded.

Original

Pixeled

bool IND_Image::Sharpen	(	float	pFactor,
		int	pIter
	)

Parameters:

pFactor "Definition" factor
pIter Numbers of iterations

Operation:

Applies a definition filter that depends of the parameters pFactor (the greater this parameter, the more "defined" the image will be) and the pIter parameter that indicates the number of times that the filter is applied consecutivity. This filter can improve the quality in images that have been deteriorated. Returns 0 if there is no image loaded.

Original

Sharpen

bool IND_Image::Scale	(	int	pSizeX,
		int	pSizeY
	)

Parameters:

pSizeX Width in p�xels
pSizeY Height in p�xels

Operation:

Applies a scale to the height and width specified as paramteres. Returns 0 if there is no image loaded.

Original

Scaled

bool IND_Image::EdgeDetect1 ( )

Parameters:

Operation:

Applies a filter of border detection (type 1). Returns 0 if there is no image loaded.

Original

Border detection type 1

bool IND_Image::EdgeDetect2 ( )

Parameters:

Operation:

Applies a filter of border detection (type 2). Returns 0 if there is no image loaded.

Original

Border detection type 2

bool IND_Image::Emboss ( )

Parameters:

Operation:

Applies a emboss filter. Returns 0 if there is no image loaded.

Original

Emboss

bool IND_Image::Rotate ( float pAngle )

Parameters:

pAngle Rotation angle

Operation:

Applies a rotation in an angle which is specified as the pAngle parameter. Returns 0 if there is no image loaded.

Original

Rotation

bool IND_Image::InvertAlpha ( )

Parameters:

Operation:

Inverts the alpha values (transparency) of the image. Returns 0 if there is no image loaded.

bool IND_Image::Saturation ( float pSaturation )

Parameters:

pSaturation Saturation quantity of the image.

Operation:

Applies a saturation filter which depends of the paramenter pSaturation. The greater this value is, the more saturated the image will be. Returns 0 if there is no image loaded.

Original

Saturation
