When I create a masked image (blue) with a rounded rect, with the same rect as the background (red), the background shows through the corners of the masked image (see attached). How can I make it so no pixels show through?
Based on the example image I think that I would do this with Clipping mask.
You could do something like:
- Create a base layer of any color. this should have the rounded corners and or other shapes.
- Create another two layers with blue and red rectangles in each one with the sides going past your base layer.
- Then in the layers panel while pressing Alt key, point in between your base layer and one of the rectangle layers vertically ( the sides that are touching ). Then click right there between them and you should have a clipping mask. Repeat this step with any additional colors / elements you might want to add to it.
Tip: I sometimes make Shape layer and then put a texture layer ( that fills the whole document ) into clipping mask with the Shape layer, that way I can resize the shape layer if needed and the texture just sits there and wont get disturbed.
