[QUOTE="knutinh, post: 69197, member: 14776"] What math is it that you are requesting actually, frodo? Btw, can the available scaling algo take any practical integer input and scale it to any practical integer output? The variables then are: Video Vx[] and Vy[] where x1 and x2 are 0 and x2 and y2 are the input video width and height respectively Video AR, a ratio giving the aspect ratio (not pixel ratio) of content in case it is non-quadratic pixel (does this ever happen?) Video content VCx[] and VCy[] providing estimated positions for true video rectangle content. Display Dx[] and Dy[] where x1 and x2 are 0 and x2 and y2 are the display video width and height respectively. Display AR, a ratio giving the aspect ratio (not pixel ratio) of content in case it is non-quadratic pixel. Most Pc displays would simply have the same number as #ypixels/#xpixels, however, typically plasma displays have #ypixels/#xpixels = 4:3 while AR is 16:9 Desired video vectors Dvx[] and Dvy[] where x1 x2 y1 y2 are kind of abstract numbers pointing anywhere inside or outside the display device allowing scalers and croppers to do their thing Desired video AR, a ratio giving the aspect ratio (not pixel ratio) of desired video . Wow, getting dizzy here... -k [/QUOTE]
