bool Picture::operator!=

(

const Picture &

p

)

const

Not-Equal operator.

void Picture::setData

(

const QImage &

data

)

Sets the image data of the picture.

When using this function, isIntern() will return 'true' until you use setUrl(). This also sets type to "png" or "jpeg" depending on whether the image has an alpha channel or not.

Parameters

data	The image data of the picture.

Definition at line 157 of file picture.cpp.

void Picture::setRawData	(	const QByteArray &	rawData,
		const QString &	type
	)
