<div>In fact you'll also not get smaller canvas when you scale the image down. outer parts of the image will be filled with black.</div><div>You can set scale to 2.0 let's say and the image will get scaled up and cropped. However this cropping is kind of not destructive.</div>
<div>Try this:</div><div>Scale the image up using "relative" option setting scale to 2.0</div><div>Then scale down the result to 0.5.</div><div>You'll get the original image back, although when looking at the result of first scale node - you see cropped image. Second scale node brings cropped pixels back.</div>
<div>The only way to get really scaled up image is to use "Scale" node and set it to "Render size". This way the canvas will get resized as well.</div><div>There is unfortunately no easy way to resize images.</div>
<div>I didn't yet find any whatsoever way to scale image up to different then render size dimensions.</div><div>There's nothing wrong with filer of blur nodes. The problems are cased by scaling that is far from being intuitive. A lot of tricks need to be performed to make it work.</div>

<div class="h5"><div dir="ltr">Hi everyone, <div>I don't know if its already a known bug or not.</div><div>I noticed that if I add a filter node on an image picture (in this case I used a sharpen but I could have added a blur as well) that has been scaled via a transform node it gets cropped to its original canvas.</div>
