Detailed Description

Class image.

Constructor & Destructor Documentation

efl::image::image ( ::efl::eo::parent_type  _p )

inlineexplicit

Constructs a new efl::image object.

Constructs a new efl::image object. If you want this object to be a child of another Eo object, use an efl::eo::parent expression, like the example.

Example:

efl::image my_image(efl::eo::parent = parent_object);

image(Eo* eo)

efl::image::image ( Eo *  eo )

inlineexplicit

Eo Constructor.

Constructs the object from an Eo* pointer stealing its ownership.

Parameters

eo	The Eo object pointer.

efl::image::image ( std::nullptr_t  )

inlineexplicit

nullptr_t Constructor.

Constructs an empty (null) object.

Member Function Documentation

bool efl::image::animated_get

(

)

const

Check if an image can be animated (have multiple frames)

Returns

whether the image support animation

Parameters

is_animated

If it's animated or not.

void efl::image::load_size_get	(	int *	w_,
		int *	h_
	)		const

Parameters

w	The new width of the image's load size.
h	The new height of the image's load size.

void efl::image::load_size_set	(	int	w_,
		int	h_
	)		const

Set the loading size of an image.

The image will be loaded into memory as if it was the set size instead of the original size. This can save a lot of memory, and is important for scalable types like svg.

Parameters

w	The new width of the image's load size.
h	The new height of the image's load size.

bool efl::image::smooth_scale_get

(

)

const

Retrieves whether the given image is using high-quality image scaling algorithm.

Returns

Whether smooth scale is being used.

Parameters

smooth_scale

Whether to use smooth scale or not.

void efl::image::smooth_scale_set

(

bool

smooth_scale_

)

const

Sets whether to use high-quality image scaling algorithm on the given image.

When enabled, a higher quality image scaling algorithm is used when scaling images to sizes other than the source image's original one. This gives better results but is more computationally expensive.

Parameters

smooth_scale

Whether to use smooth scale or not.

double efl::image::ratio_get

(

)

const

The native ration of the image object.

Parameters

ratio

The image's ratio
