#1370 How to resize a sprite?
How can I resize a sprite in jpexs? I would love to know!
In current version, you can resize instances of the sprite by selecting the PlaceObject tag on frame and clicking Edit. This gives you freetransform tool. To resize whole sprite you must resize all things it contains - via editing the PlaceObject tags.
In nightly 2331 you can transform whole sprite at once.
