Parameters:

aFileName

The name of the file to load.

Returns:

True if successful.

Boolean bps::Pixmap::loadFromData

(

ByteArray

aData

)

Load a pixmap from memory data.

The image type is detected automatic by the data. This loader function will typically be used to load pictures stored in a database BLOB.

Parameters:

aData

The data with the picture file contents to load.

Returns:

True if successful.

Boolean bps::Pixmap::save

(

const QString &

aFileName

)

Save pixmap to a file.

Parameters:

aFileName

The file name to store the pixmap. The extension of the filename is used to determine the type (png, jpg, bmp, ...)

Returns:

True when successful.

ByteArray bps::Pixmap::saveToData

(

const QString &

aFormat

)

Save pixmap to in memory data in a file format.

Parameters:

aFormat

The file format (png, jpg, bmp, ...)

Returns:

The saved pixmap.

String bps::Pixmap::toString

(

)

const

Returns:

Returns "Pixmap(width x height)"
