automatic scaling

[rlh001]

The Vizard window opens at 800 x 600 pixels and the image looks proportioned properly. When I Maximize the window the image is distorted unless I change the scaling with the code below, but then it distorts the image when the window is not maximized. I need to have the image appear undistorted regardless of window sizing. Thanks

##Add Instrument Cluster Image to Screen
clusterTex = viz.addTexture('resources\ClusterGraphics.png')
clusterQuad = viz.addTexQuad(viz.SCREEN)
clusterQuad.texture(clusterTex)
# Increase size of image
clusterScale = 2.75
#Modify Aspect ratio to look correct when changed to full screen
clusterAspectRatio= 1.75 # full screen 1280:800
clusterQuad.setScale(clusterScale * clusterAspectRatio, clusterScale )

Add the quad to viz.ORTHO instead of viz.SCREEN. Objects added to viz.ORTHO will maintain the same pixel size and aspect ratio, regardless of the window size. The scale and position of the object will need to be specified in pixels though.

clusterTex = viz.addTexture('resources\ClusterGraphics.png') 
clusterQuad = viz.addTexQuad(parent=viz.ORTHO)
clusterQuad.texture(clusterTex)

# Set size of quad to size of texture
clusterQuad.setScale(clusterTex.getSize())
