Hi Eric,
You might find this function useful:
function rescale theImgWidth,theImgHeight,theCdWidth,theCdHeight
if theCdWidth/theImgWidth < theCdHeight/theImgHeight then
put theCdWidth / theImgWidth into myRatio
else
put theCdHeight / theImgHeight into myRatio
end if
put theImgWidth * myRatio into myNewWidth
put theImgHeight * myRatio into myNewHeight
return myNewWidth,myNewHeight
end rescale
TheImgWidth and theImgHeight are the original width and height, e.g. the
formattedWidth and formattedHeight of an image object, and the CdWidth and
theDcHeight are the width and height of the destination area. It returns the
new height and width for your object, with correct aspect ratio.
