Detailed Description

Container of a set of surfaces.

Used to manage single images that contain series of frames inside, like animated sprites, making them easier to access without constant cropping.

Constructor & Destructor Documentation

SurfaceSet() [1/2]

OpenXcom::SurfaceSet::SurfaceSet	(	int	width,
		int	height
	)

Crates a surface set with frames of the specified size.

Sets up a new empty surface set for frames of the specified size.

Parameters

width	Frame width in pixels.
height	Frame height in pixels.

SurfaceSet() [2/2]

OpenXcom::SurfaceSet::SurfaceSet

(

const SurfaceSet &

other

)

Creates a surface set from an existing one.

Performs a deep copy of an existing surface set.

Parameters

other

Surface set to copy from.

~SurfaceSet()

OpenXcom::SurfaceSet::~SurfaceSet

(

)

Cleans up the surface set.

Deletes the images from memory.

Member Function Documentation

addFrame()

Surface * OpenXcom::SurfaceSet::addFrame

(

int

i

)

Creates a new surface and returns a pointer to it.

Creates and returns a particular frame in the surface set.

Parameters

i	Frame number in the set.

Returns

Pointer to the respective surface.

getFrame()

Surface * OpenXcom::SurfaceSet::getFrame

(

int

i

)

Gets a particular frame from the set.

Returns a particular frame from the surface set.

Parameters

i	Frame number in the set.

Returns

Pointer to the respective surface.

getHeight()

int OpenXcom::SurfaceSet::getHeight

(

)

const

Gets the height of all frames.

Returns the full height of a frame in the set.

Returns

Height in pixels.

getTotalFrames()

size_t OpenXcom::SurfaceSet::getTotalFrames

(

)

const

Gets the total frames in the set.

Returns the total amount of frames currently stored in the set.

Returns

Number of frames.

getWidth()

int OpenXcom::SurfaceSet::getWidth

(

)

const

Gets the width of all frames.

Returns the full width of a frame in the set.

Returns

Width in pixels.

loadDat()

void OpenXcom::SurfaceSet::loadDat

(

const std::string &

filename

)

Loads an X-Com DAT image file.

Loads the contents of an X-Com DAT image file into the surface.

Unlike the PCK, a DAT file is an uncompressed image with no offsets so these have to be figured out manually, usually by splitting the image into equal portions.

Parameters

filename

Filename of the DAT image.

loadPck()

void OpenXcom::SurfaceSet::loadPck	(	const std::string &	pck,
		const std::string &	tab = ""
	)

Loads an X-Com set of PCK/TAB image files.

Loads the contents of an X-Com set of PCK/TAB image files into the surface.

The PCK file contains an RLE compressed image, while the TAB file contains the offsets to each frame in the image.

Parameters

pck	Filename of the PCK image.
tab	Filename of the TAB offsets.

setPalette()

void OpenXcom::SurfaceSet::setPalette	(	SDL_Color *	colors,
		int	firstcolor = 0,
		int	ncolors = 256
	)

Sets the surface set's palette.

Replaces a certain amount of colors in all of the frames.

Parameters

colors	Pointer to the set of colors.
firstcolor	Offset of the first color to replace.
ncolors	Amount of colors to replace.
