1.	By changing the dimensions of the viewport, the _________ and ___________ of the objects being displayed can be manipulated.(a) Number of pixels and image quality(b) X co-ordinate and Y co-ordinate(c) Size and proportions(d) All of theseThe question was asked by my college director while I was bunking the class.My doubt is from Window to Viewport Coordinate Transformation topic in section 2D Transformation and Viewing of Computer Graphics
Answer» Right option is (C) Size and proportions For explanation: By changing the DIMENSIONS of the VIEWPORT, the size and proportions of the objects being displayed can be manipulated, this leads to the zooming effect of the image by SUCCESSIVELY mapping different dimensioned clipping windows on a fixed SIZED viewport.
