So im a primary student that just started to use coreldraw for my task of making a design of a food packaging. So there's 2 image, one is a background and one is a nugget pict with transparent background that i downloaded from google. I put the nugget pict above the background pict, then i save the file as a PNG. When i open the file, the nugget pict still has the transparent background shown, which is a mosaic background that covers the first background image. Can someone help me how to get rid of this mosaic transparent background?
By the way im asking this question in the community because i dont find this case in youtube, and i dont know what keyword should i use for this kind of thing
