Detailed Description

This manager that stores IND_Image objects works as a mediator between the image (bitmap) loaded in memory and the IND_Surface object which finally appears in the screen. The IND_Image objects which are stored in this class can not be rendered directly to the screen. But this class is very useful for applying filters (like in Gimp or Photoshop programs) to loaded images, and later they can be converted to IND_Surface objects, which can be directly rendered.

Other possible uses of this class are:

• Hardness maps. Used for making collisions or path finding.
• GetPixel() / PutPixel()
• Colorkey. By changing a certain color into transparent using SetAlpha().
• Generation of new images (procedurally).
• Convert formats. Changing the number of bytes per pixel using Convert()
• Direct accesing to the bitmap. Using IND_Image::GetPointer()

Member Function Documentation

bool IND_ImageManager::Init

(

)

This function returns 1 (true) if the adminstrator is successfully initialized. Must be called before using any method.

void IND_ImageManager::End

(

)

Operation:

This function frees the manager and all the objects that it contains.

bool IND_ImageManager::Add	(	IND_Image *	pNewImage,
		char *	pName
	)

Parameters:

• pNewImage Pointer no a new image object.
• pName Image name

Operation:

This function returns 1 (true) if the image object passed as a parameter exists and is added successfully to the manager.

It supports the following graphics formats (thanks to http://openil.sourceforge.net): bmp, png, tga, jpg y pcx.

bool IND_ImageManager::Add	(	IND_Image *	pNewImage,
		int	pWidht,
		int	pHeight,
		IND_Format	pFormat
	)

Parameters:

• pNewImage Pointer to a new image object
• pWidth Width of the new image
• pHeight Height of the new image
• pFormat New image format. See IND_Format.

Operation:

This function returns 1 (true) if the image object passed as a parameter exists and is added successfully to the manager creating a new procedural image.

By default, the new image is not initialized to any color, you should used the Clear() method in order to assing a valid colour.

bool IND_ImageManager::Delete

(

IND_Image *

pIm

)

Parameters:

• pIm Pointer to an image object.

Operation:

This function returns 1(true) if the image object passed as parameter exists and it is deleted from the manager successfully.

bool IND_ImageManager::Save	(	IND_Image *	pIm,
		char *	pName
	)

Parameters:

• pName Image name

Operation:

This function returns 1 (true) if the image object passed as a parameter exists and saves this image in a file with extension and type specified in the name.

It supports the following graphics formats (thanks to http://openil.sourceforge.net): bmp, png, tga, jpg and pcx.

bool IND_ImageManager::Clone	(	IND_Image *	pNewImage,
		IND_Image *	pOldImage
	)

Parameters:

• pNewImage Pointer to a new image object
• pOldImage Pointer to the image we want to clone

Operation:

This function returns 1 (true) if the image object passed as a parameter exists and is added successfully to the manager creating a new image cloning from a previous one.
