Detailed Description

Extends kTexture with 2D-specific metadata and optional CPU-side pixel data.

Pixel data is optionally retained after upload (when keepData is true in kAssetManager::loadTexture2D) for later CPU access.

Constructor & Destructor Documentation

kTexture2D()

kemena::kTexture2D::kTexture2D

(

)

Constructs an empty 2D texture with zeroed metadata and no pixel data.

~kTexture2D()

virtual kemena::kTexture2D::~kTexture2D ( )

virtual

Destroys the 2D texture and releases any retained CPU-side pixel data.

(

)

Returns the number of colour channels.

Returns

Channel count.

getData()

unsigned char * kemena::kTexture2D::getData

(

)

Returns the CPU-side pixel data pointer.

Returns
