Constructor Detail

Image

public Image(int w,
             int h)

Create an Image object of a give size, but no image yet. UNH extension. rdb 11/15/09

public Image(int w,
             int h,
             int iType)

Create an Image object of a give size and type but no image yet. UNH extension. rdb 11/15/09

Image

public Image(java.lang.String file)

Create an image from the specified filename, in the wheelsunh.users.Frame's DrawingPanel. Note that if you are running on Windows, the location of the image must be in your classpath.

Parameters:

file - the filename to take this image form (gif or jpg).

Image

public Image(java.net.URL url)

Create an image from the specified URL, in the wheelsunh.users.Frame's DrawingPanel.

Parameters:

url - the URL to take this image form (gif or jpg)

Image

public Image(DrawingPanel dp,
             java.lang.String file)

Create an image from the specified filename, in the specified DrawingPanel. Note that if you are running on Windows, the location of the image must be in your classpath.

Parameters:

dp - the DrawingPanel for this image

file - the filename to take this image form (gif or jpg).

Image

public Image(DrawingPanel dp,
             java.net.URL url)

Create an image from a URL.

Parameters:

dp - the DrawingPanel for this image

url - the URL to take this image form (gif or jpg)

Image

public Image(java.awt.Image awtImage)

Parameters:

awtImage -

Method Detail

setup

protected void setup(DrawingPanel dp)

Normal users need not use this!

Use the media tracker to load the image, then initialize everything else.

setAWTImage

protected void setAWTImage(java.awt.Image newImage)

set the internal awt version of the image; UNH extension: On MacOSX, we get image objects of type apple.awt.OSXImage. They may be more efficient, but makes it difficult to do anything with them in a system independent way. Check for that, and convert to a BufferedImage. Maybe we should call it a BufferedImage instead of just Image??
