Display an image on a widget.
This class is used to display static images. It provides automatic mipmap management. Desired level-of-detail is handled automatically by choosing a proper mipmap level based on the pixel size of the image on screen to reduce aliasing artifacts. Only required detail levels are kept in memory and others are pruned to reduce memory footprint and improve performance. The mipmap pyramid is stored on disk in image cache and it is generated for every image when the image is accessed for the first time. The image cache persist through application restarts. The image cache generation will take some time, but once it is generated subsequent loads are much faster.
This class has the following CSS pseudo-state (See also BaseMediaWidget):
|
explicit |
Construct an empty ImageWidget.
| parent | Parent widget |
| bool MultiWidgets::ImageWidget::compressedMipmaps | ( | ) | const |
If enabled, CPUMipmaps uses DXT compressed mipmap images, that are significantly faster to load and take much less memory on both CPU and GPU.
However, their image quality might be worse, specially with images with gradients. DXT mipmaps are generated and saved to DDS image cache on the first time they are loaded.

Entry point for incoming events Class specific behaviour to events is implemented in this function.
See Event System -section in Developer Guide for in-depth discussion about events in Cornerstone.
Overriding: Inherited classes can override this function for implementing custom behaviour for events. When overriding this function one needs to remember to call base-class implementation for discarded events. Otherwise large portion of the inherited behaviour gets incomplete.
See example about overriding below:
| id | Name of the incoming event. |
| data | Data associated to the incoming event. |
Reimplemented from MultiWidgets::Widget.
| ImageWidget::FilterMode MultiWidgets::ImageWidget::filterMode | ( | ) | const |
Specifies the filter mode when filtering image mipmaps.
By default, we use trilinear filtering that blends between two mipmap levels when necessary. Using bilinear filtering instead when rendering many images can increase performance at the cost of noticeable jumps when switching mipmap levels.
|
virtual |
Get the native size of the displayd image.
This function will return the native pixel size of loaded image. If no image is loaded, it will return (100, 100).
Reimplemented from MultiWidgets::Widget.
|
virtual |
Checks if the given point is inside the widget.
If the point is inside, the point is tested against transparency of the image.
| v | point in widget coordinates |
Reimplemented from MultiWidgets::Widget.
| Radiant::FutureBool MultiWidgets::ImageWidget::load | ( | const QString & | filepath, |
| LoadBlockType | blockUntil = HEADER_READY |
||
| ) |
Load an image from the given filename.
This function loads an image from the disk in a background thread. It can operate in both synchronous and asynchronous modes. The function returns a future boolean. If the return value is accessed, the operation will block until the value of the future boolean is available. This will depend on the selected blocking type. If the return value is not accessed, the load will happen asynchronously. This function ensures that the widget is kept alive until all onHeaderReady/onReady/onError callbacks are triggered, even if the widget doesn't have any outside references.
| filepath | file to load |
| blockUntil | how long to block in synchronous mode |
| int MultiWidgets::ImageWidget::minimumSolidAlpha | ( | ) | const |
Specifies an alpha threshold value that is used for determining input on transparent pixels.
If a pixel alpha value is smaller than this value isInside returns false for that pixel.
|
protectedvirtual |
Render the content of the Widget.
This function is called from the main render function. Does nothing by default.
Overriding: Usually custom rendering of the widget should go here. This is empty by default so there is no need to call the implementation of the base class.

Update widget state.
This function is called by the application during its update step. This function may be called several times per rendered frame. This function is always called after input() and before render(). If you need to know if this call is the last update for this rendered frame, use the FrameInfo::isLastUpdate(). The default implementation is empty.
| frameInfo | Frame information since last update call |
Reimplemented from MultiWidgets::Widget.
Reimplemented in MultiWidgets::ResizeHandleWidget.
