Constructor & Destructor Documentation

ScreenImage::ScreenImage ( const QString &  filename,
float  x,
float  y,
bool  show = false,
float  scale = 1.,
float  alpha = 1.,
float  fadeDuration = 1. 
)

Load an image.

Parameters:
filename the partial path of the file to load. This will be searched for in the scripts directory using StelFileMgr.
x the screen x-position for the texture (in pixels), measured from the left side of the screen.
y the screen x-position for the texture (in pixels), measured from the bottom of the screen.
show the initial displayed status of the image (false == hidden).
scale scale factor for the image. 1 = original size, 0.5 = 50% size etc.
fadeDuration the time it takes for screen images to fade in/out/change alpha in seconds.

Member Function Documentation

virtual void ScreenImage::addXY ( float  x,
float  y,
float  duration = 0. 
) [virtual]

Set the x, y position of the image relative to the current position.

Parameters:
x the offset in the x-axis
y the offset in the y-axis
duration how long for the movement to take in seconds
virtual bool ScreenImage::draw ( const StelCore core  )  [virtual]

Draw the image.

Parameters:
core the StelCore object
virtual void ScreenImage::setAlpha ( float  a  )  [virtual]

Set the image alpha for when it is in full "on" (after fade in).

Parameters:
a the new alpha (transparency) for the image. 1.0 = totally transparent, 0.0 = fully opaque.
duration the time for the change in alpha to take effect.
virtual void ScreenImage::setFlagShow ( bool  b  )  [virtual]

Show or hide the image (it will fade in/out).

Parameters:
b if true, the image will be shown, else it will be hidden
virtual void ScreenImage::setXY ( float  x,
float  y,
float  duration = 0. 
) [virtual]

Set the x, y position of the image.

Parameters:
x new x position
y new y position
duration how long for the movement to take in seconds
