\brief Album Cover Widget.
|
|
|
26 |
This widget provides up scaled rendering of images and SVG rendering.
|
|
|
27 |
|
|
|
28 |
This widget can be used instead of HbLabel or HbIconItem when up scaling
|
|
|
29 |
and downscaling during painting is desired, there is no need to preprocess
|
|
|
30 |
images to the target size, this is taken care of during paint in a more
|
|
|
31 |
efficient manor; this widget renders images flush with the geometry.
|
|
|
32 |
Default icon placeholder is also supported.
