I used Photoshop to apply a static image to the green flag sprite and imported it back into Scratch.
this is the flag —–> blob:null/36ea0f77-9b11-42dd-b8fd-6f534bbe955f

I want to erase a part of it, but for some reason it just does not work.
Uploaded back to Scratch costume editor when I was done working on it.
I do NOT want to convert to bitmap as it is just too pixely.
I want to use it for a thumbnail.
Any ideas on what is happening/what to do???

Vectors are constituted of shapes, while bitmaps are made of pixels. You can’t erase part of a vector image without converting it over to bitmap first, otherwise you’ll have to use third-party software to erase the desired section while retaining the original resolution.

ok thanks
