Constructor and destructor.

◆ ~View2DIcons()

Member Function Documentation

◆ addIcon()

bool View2DIcons::addIcon ( const char * filename )

add icon from file

◆ addIcons()

bool View2DIcons::addIcons	(	const char *	filename,
		int	width,
		int	height
	)

add icons from file by splitting the file into width x height blocks

◆ clearIcons()

void View2DIcons::clearIcons ( )

clear all icons

◆ drawIcon()

void View2DIcons::drawIcon	(	int	idx,
		float	dx1,
		float	dy1,
		float	dx2,
		float	dy2
	)

draw the icon at index i

◆ drawIconAsBorderImage()

void View2DIcons::drawIconAsBorderImage	(	int	idx,
		float	dx1,
		float	dy1,
		float	dx2,
		float	dy2,
		float	borderWidth,
		float	borderHeight
	)

draws the given icon from dx1,dy1 to dx2,dy2 using 3x3 quads (the corners/border regions defined by borderWidth and borderHeight (in texels) are not stretched while the rest of the image is stretched to fill the box) For example usages, google for "css border-image".

NOTE: This method only supports textures that are smaller than the maximum GL texture size.

◆ fetchImageDimensions()

bool View2DIcons::fetchImageDimensions	(	const char *	filename,
		int &	imageWidth,
		int &	imageHeight
	)

Loads an image with the given filename and returns whether the loading was successful.

Sets imageWidth and imageHeight on successful loading; otherwise, they are set the -1.

◆ getIcon()

View2DTexture * View2DIcons::getIcon ( int index )

get icon at index

◆ numIcons()

int View2DIcons::numIcons ( )

get number of icons

◆ removeIcon()

void View2DIcons::removeIcon ( int index )

remove an icon
