QtImage
public QtImage(byte[] data)
Constructs a QtImage from a byte array of an image file.
QtImage
public QtImage(int width,
int height)
Constructs an empty QtImage.
QtImage
public QtImage(ImageProducer producer)
Creates the image from an ImageProducer. May result in an error image.
QtImage
public QtImage(String filename)
Constructs a QtImage by loading a given file.
QtImage
public QtImage(URL url)
Creates the image from a URL. May result in an error image.
clear
public void clear()
Clears the image to RGBA 0
copyArea
public void copyArea(int x,
int y,
int width,
int height,
int dx,
int dy)
drawImage
public boolean drawImage(QtGraphics g,
int dx1,
int dy1,
int dx2,
int dy2,
int sx1,
int sy1,
int sx2,
int sy2,
Color bgcolor,
ImageObserver observer)
Draws an image with eventual scaling/transforming.
drawImage
public boolean drawImage(QtGraphics g,
int x,
int y,
int width,
int height,
Color bgcolor,
ImageObserver observer)
Draws an image to the QtGraphics context, at (x,y) scaled to
width and height, with optional compositing with a background color.
drawImage
public boolean drawImage(QtGraphics g,
int x,
int y,
Color bgcolor,
ImageObserver observer)
Draws an image to the QtGraphics context, at (x,y) with optional
compositing with a background color.
flush
public void flush()
If the image is loaded and comes from an ImageProducer,
regenerate the image from there.
I have no idea if this is ever actually used. Since QtImage can't be
instantiated directly, how is the user to know if it was created from
an ImageProducer or not?
- flush in interface Image
setImage
public void setImage(int width,
int height,
int[] pixels,
Hashtable<K,V> properties)
Callback from the image consumer.
