I've been trying to do this all sorts of ways and now my brain is locked. I'm sure once the answer comes back at me I'll feel like a dope. Thanks in advance for killing my self esteem.
I've got a bunch of images that I need to scale to fit a maxWidth and maxHeight; trouble is these images are all sorts of possible dimensions. Say we want to fit a 320x240 area, if I request a rescaling for a rect of 640x480, it will of course check for whether the requested rect is landscape or portrait, and scale it to meet the 320x240. This works fine for this: (taken from the handyman's digital portfolio at doug and changed slightly, whereas tMax and tMin are passed in): -- if tMem.width > tMem.height then -- newHeight = (tMem.height * pMax)/tMem.width -- offset = (pMax - newHeight)/2 -- imRect = rect(0,0,pMax, newHeight) -- destRect = rect(0,0+offset, pMax, newHeight + offset) -- else -- newWidth = (tMem.width * pMin)/tMem.height -- offset = (pMin-newWidth)/2 -- imRect = rect(0,0,newWidth, pMin) -- destRect = rect(0+offset, 0, newWidth + offset, pMin) -- end if but this really doesn't work, as the image passed in might not fit perfectly to a max/min -- it's really got to scale the image to fit whichever - the maxwidth or maxheight, no matter what the image dimensions are, ie: tPerc = (maxWidth/float(theRect.width) return(rect * tPerc) ?
