詳解

MGImage defines bit map image data.

MGImage defines the attributes of Image. MGImage's behavior is just like std::auto_ptr<>. That is , newed area of m_image is transfered if copied, of assined.

関数詳解

MGImage* MGImage::clone ( ) const

Generate a cloned MGImage. Returned is newed one, must be deleted. clone() does not affect this image data.

void MGImage::copy_color ( const MGImage & image2 )

void MGImage::copy_color	(	const MGImage &	image2,
		const std::vector< int > &	ranges
	)

引数

image2	Source image data.
ranges	Ranges(j,i1,i2) are input. ranges indicate the places of both this and image2.

void MGImage::fill_color ( const MGPixel & pdata )

Fill all the pixel of this with the input color pdata.

void MGImage::fill_color	(	const MGPixel &	pdata,
		int	j,
		int	i1,
		int	i2
	)

Fill all the pixels of the range (j, i1,i2) with the input color pdata.

void MGImage::fill_color	(	const MGPixel &	pdata,
		const std::vector< int > &	ranges
	)

Fill all the pixels of ranges with the input color pdata.

void MGImage::fill_color_NoChangeAlpha ( const MGPixel & pdata )

void MGImage::fill_color_NoChangeAlpha	(	const MGPixel &	pdata,
		int	j,
		int	i1,
		int	i2
	)

(j, i1,i2) で指定された全てのピクセルについて、

int MGImage::height ( ) const

inline

MGPixel* MGImage::image ( )

inline

const MGPixel* MGImage::image ( ) const

inline

bool MGImage::includeNonZeroAlpha	(	int	i,
		int	j
	)		const

bool MGImage::is_zero_alpha	(	int	i,
		int	j
	)		const

Test if pixel at (i,j) has zero_alpha value. Returns true if alpha value is zero.

MGPixel& MGImage::operator()	(	int	i,
		int	j
	)

const MGPixel& MGImage::operator()	(	int	i,
		int	j
	)		const

MGImage& MGImage::operator= ( const MGImage & image2 )

image2.m_image's ownership is transfered to this.

void MGImage::resize	(	int	width,
		int	height
	)

resize the image size to (width,height). Scaling the whole image to the size (width, height).

void MGImage::resize_and_add_zero_border	(	int	nwidth2,
		int	nheight2
	)

Add border color(0,0,0,0)=(alfa=0) of pixel size2 for each perimeter.

void MGImage::resize_with_fill_color	(	int	width,
		int	height,
		const MGPixel &	pdata
	)

resize the image size to (width,height) filling the color to the extra part for the size(width,height). resize_with_fill_color() does not perform scaling to the image. width and height can be less than the original length. In this case, image trimming will be done.

int MGImage::width ( ) const
