BloomEffect is a post-processing effect that applies a blur to the brightest parts of scene to simulate a fuzzy glow.
The effect can be configured to change the threshold defining the bright parts of the scene and the amount of blurring to apply.
The BloomEffect is a combination of the ThresholdEffect and the GaussianBlurEffect.

This property holds the number of blur passes
This is the number of times to apply the blur to the bright parts of the scene. More passes result in stronger blurring effect but take longer to render.
Access functions:
| int | blurPassCount() const |
| void | setBlurPassCount(int blurPassCount) |
Notifier signal:
| void | blurPassCountChanged(int blurPassCount) |
See also GaussianBlurEffect::blurPassCount.
This property holds the brightness level determining which pixels the effect are applied to
This value determines how bright something has to be for the bloom effect to be applied to it. Any pixels below the threshold are ignored.
Access functions:
| float | threshold() const |
| void | setThreshold(float threshold) |
Notifier signal:
| void | thresholdChanged(float threshold) |
See also ThresholdEffect::threshold.
