load()

Reimplemented in gImage.

loadMask()

unsigned int gTexture::loadMask

(

const std::string &

fullPath

)

Loads the mask texture/image to be applied to this instance.

It requires full path of the texture/image file.

The texture/image might be stored anywhere on the hard disk or other storage devices out of the project folder.

Parameters

fullPath

The full path to the image or texture file. It should contain the full path of the folder where the image is located, the name of the image and its extension. It is case sensitive.

Returns

Image id number generated by OpenGL.

loadMaskTexture()

unsigned int gTexture::loadMaskTexture

(

const std::string &

maskTexturePath

)

Loads the mask texture/image to be applied to this instance.

It requires the name of the texture/image file (ex: "mask.png").

The image might be stored anywhere on the hard disk or other storage devices out of the project folder.

Project's default folder for masks is ProjectLocation/assets/textures directory.

Parameters

maskTexturePath

The fullname of the texture/image stored under project's images folder. maskTexturePath should contain texture/image name and its extension. It is case sensitive.

Returns

Image id number generated by OpenGL.
