I know it's possible and I know it's simple really, but I can't remember it/figure it out!
I have a sub-stack that contains an image. I want the user to be able to drag the corners and edges of the sub-stack window to make the window and its image larger or smaller, but the window and image must maintain their original aspect ratio – no stretching, no empty borders etc. I've tried the following in the card script: global gImageRatio on resizeStack pNewWidth, pNewHeight, pOldWidth, pOldHeight propSizeImage "coinSet", gImageRatio pass resizeStack end resizeStack on propSizeImage pImageName, @pImageRatio put the width of this stack into propWidth set the width of image pImageName to propWidth put propWidth div pImageRatio into propHeight put the width of image pImageName into tWidth put the height of image pImageName into tHeight if propHeight > tHeight then put tHeight into propH put tHeight * pImageRatio into propW else if propHeight < tHeight then put propHeight into propH put propH * pImageRatio into propW else put tWidth into propW put tHeight into propH end if set the height of image pImageName to propH set the width of image pImageName to propW set the height of this stack to propH set the width of this stack to propW set the topLeft of image pImageName to 0,0 end propSizeImage with the following initialisation in the stack script: global gImageRatio on preOpenStack put the width of image "CoinSet" / the height of image "CoinSet" into gImageRatio end preOpenStack I'm probably missing something obvious, but can anyone help please?!
