Re: New to Get a Copy of Scaled Down Version of an Image
Try changing this line: put tImageData["image"] into image "currentpuzzle" to this: set the imageData of image "currentpuzzle" to tImageData["image"] -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com On October 28, 2020 6:06:39 AM Sannyasin Brahmanathaswami via use-livecode wrote: 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 end resizeToWidth How do I get a copy, with the image scaled down, which is visible on screen?

I wanted to get a scaled down version? How do we implement this, from the dictionary The imageData, unlike the contents of the image container, is based on the picture as it's presented on the screen, not stored in the image object. This means that if you resize an image, the content of the image does not change, but its imageData does. If you create an image and then reduce its size, its imageData reflects the scaled-down, displayed image, not the original full-scale image. If you create a second image and set its imageData property to the imageData of the original image, resizing the first image back to the original dimensions displays the original image at full resolution, but resizing the second image does not, because setting its imageData transferred only the scaled-down version of the original.
