Detailed Description

A grid-indexed collection of sf::IntRect regions.

ImageRects stores the sub-rectangle regions produced by TextureSlicer::getImageRects when a texture is divided into a uniform grid of rows and columns. Each rect describes the pixel bounds of one cell within the source texture, ready to be passed to sf::Sprite::setTextureRect for sprite-sheet animation or tile-based rendering.

Rects are stored in row-major order and accessed by (row, col) index.

Usage

ml::ImageRects rects = ml::TextureSlicer::getImageRects(spriteSheet, 4, 8);
 
// Access frame (row 1, col 3)
sprite.setTextureRect(rects.getIntRect(1, 3));

Constructor & Destructor Documentation

ImageRects()

ml::ImageRects::ImageRects

(

int

cols

)

Construct an empty ImageRects with a known column count.

Parameters

cols	Number of columns in the source grid. Used to convert (row, col) indices to a flat vector position.

Member Function Documentation

getIntRect()

const sf::IntRect & ml::ImageRects::getIntRect	(	int	row,
		int	col )

Return the rect for a given row and column.

Parameters

row	Zero-based row index.
col	Zero-based column index.

Returns

Const reference to the sf::IntRect for that cell.

push()

void ml::ImageRects::push

(

const sf::IntRect &

int_rect

)

Append a rect to the collection.

Called by TextureSlicer to populate the collection in row-major order. Direct use is uncommon outside of framework internals.

Parameters

int_rect

The rect to append.
