QStringList getAllImageIDs(void)
Get a list of currently loaded image IDs.
void deleteAllImages(void)
Delete all images currently managed by ScreenImageMgr.
virtual bool getFlagShow(void)
Get the displayed status of the image.
void deleteImage(const QString &id)
Delete an image.
Module for managing images for scripting.
Definition: ScreenImageMgr.hpp:104
virtual bool draw(const StelCore *core)
Draw the image.
Define the StelTextureSP type.
virtual void setFadeDuration(float duration)
Set the duration used for the fade in / fade out of the image.
Main class for Stellarium core processing.
Definition: StelCore.hpp:46
virtual void setXY(float x, float y, float duration=0.)
Set the x, y position of the image.
virtual void setFlagShow(bool b)
Show or hide the image (it will fade in/out)
virtual void addXY(float x, float y, float duration=0.)
Set the x, y position of the image relative to the current position.
virtual double getCallOrder(StelModuleActionName actionName) const
Defines the order in which the various modules are drawn.
virtual void draw(StelCore *core)
Execute all the drawing functions for this module.
virtual void setAlpha(float a)
Set the image alpha for when it is in full "on" (after fade in).
virtual void init()
Initialize itself.
void setImageXY(const QString &id, float x, float y, float duration=0.)
Set the x and y coordinates for the specified image.
void setImageAlpha(const QString &id, float alpha)
Set an image's alpha value when visible.
StelModuleActionName
Define the possible action for which an order is defined.
Definition: StelModule.hpp:120
void createScreenImage(const QString &id, const QString &filename, float x, float y, float scale=1., bool visible=true, float alpha=1., float fadeDuration=1.)
Create an image from a file and display on the screen at x,y coordinates.
bool getShowImage(const QString &id)
Find out if an image is currently visible.
ScreenImageMgr()
Construct a LabelMgr object.
virtual void update(double deltaTime)
