Take for example
[command] resizeToWidth tImage, 400
on resizeToWidth pImage,pSize
local tOrigImgWidth, tOrigImgHeight, tRatio, tNewWidth, tNewHeight
set the itemdel to "x"
put item 1 of sCurrentGraphicRect into tOrigImgWidth
put item 2 of sCurrentGraphicRect into tOrigImgHeight
if tOrigImgWidth is 0 then exit resizeToWidth
put pSize/tOrigImgWidth into tRatio
put (tOrigImgHeight * tRatio) into tNewHeight
put (tOrigImgWidth * tRatio) into tNewWidth
set the rect of pImage to 0,0,tNewWidth,tNewHeight
How do I get a copy, with the image scaled down, which is visible on screen?
if (the width of tImage > the heigth of tImage ) then
resizeToWidth tImage, 400
resizeToHeigth tImage, 400
# now we set the img to the img "currentpuzzle"
set the name of the last image to "currentpuzzle"
# and copy the data, at 400px wide
put the rect of the last image into tImageData["rect"]
put the imageData of the last image into tImageData["image"]
put tImageData["image"] into image "currentpuzzle"
BUT the full scaled copy of the image "currentpuzzle" comes into view. I wanted to get a scaled down version?
