Graphics

I'm trying to modify a script that sets the scales an image to the maximum width/height based on the widthset/heightset variables. I'd like to be able to scale the image to a minimum width/height but I can't wrap my head around the maths.

[CODE]'get aspect ratio

picMat.GetDimensions(imageWidth, imageHeight)

aspect = imageWidth / imageHeight

'This the code I'd like to edit so that if minmax="MIN" it will scale an image to a minimum width or height

if ucase(minmax)="MAX" then

if imageHeight > imageWidth then

scaleY = heightset / currHeight

scaleX = (heightset * aspect) / currWidth

else

scaleX = widthset / currWidth

scaleY = (widthset / aspect) / currHeight

end if

end if

It seems to be behaving better on my second attempt. I don't know why I was having such trouble. I set up the script so that the ScaleX/ScaleY equations in each 'if statement' mirror each other and moved the calculation of the aspect ratio into the 'if statements', and I made sure the aspect ratio calculates to be 1 or greater. This cleared up some confusion for me and for whatever reason it started working correctly.

else if ucase(minmax)="MIN"

if imageHeight < imageWidth then 'Apply calculate final dimensions

aspect = imageWidth / imageHeight

scaleY = heightset / currHeight

scaleX = (heightset * aspect) / currWidth

else

aspect = imageHeight / imageWidth

scaleX = widthset / currWidth

scaleY = (widthset * aspect) / currHeight

end if

else
