			Screen Size and Scaling

		Hi, 
I have two questions regarding screen size and scaling of objects. Here I have attached two images (one original texture and one screen shot of the texture placed in two orientations). I have also annotated the screen shot for clarification. I have two issues, - In order to achieve an equal width of arrows (green lines in the screen shot), I have to adjust the window size to something like [760, 600]. How can I calculate these values? Further information regarding the size of the original texture and my display setting is gone in the bottom.
 
- My other issue is the ratio of width to height of the texture (green to blue lines in the screen shot). The original texture looks much slimmer than the ones displayed. I use 'setScale' method to adjust the x and y scales differently (the blue line in the code below). When we add the texture, we specify a size. For that, I use one number, which I assume it defines a square. How can I merge this scaling in the line in blue with texture size in the line in red?
 
 Some information on the original texture and my display settings, - The original image: 600 x 780 pixels, 72 x 72 pixels per inch resolution
 
- The display: 1920 x 1200 LCD monitor.
 
 The code that I used to create display the arrows:
 
	Code: 
	
 import viz 
 
viz.window.setSize([760, 600]) 
 
viz.go() 
 
TextureArrow = viz.addTexture('Bank, Task\Arrow, Original.png') 
 
DispArrow1 = viz.addTexQuad(viz.SCREEN, viz.MainScene, 500) 
DispArrow1.setScale([600.0 / 780, 780.0 / 780, 1]) 
DispArrow1.setPosition([0.7, 0.7, 0]) 
DispArrow1.setEuler([0, 0, 90], mode = viz.ABSOLUTE) 
DispArrow1.texture(TextureArrow) 
 
DispArrow2 = viz.addTexQuad(viz.SCREEN, viz.MainScene, 500) 
DispArrow2.setScale([600.0 / 780, 780.0 / 780, 1]) 
DispArrow2.setPosition([0.5, 0.3, 0]) 
DispArrow2.setEuler([0, 0, 0], mode = viz.ABSOLUTE) 
DispArrow2.texture(TextureArrow) 
 Very many thanks for your attention.
 
Greetings,
