pict.resize(); pict.resize(0.1, 0.1); The Problem: When the top-left corner of the picture is in the very first row (Row1 = 0) or the very first column (Col1 = 0), the resizing logic gets confused and does not calculate the size of the picture correctly.

Why does Picture.resize() fix it? When you call Picture.resize() first, it makes sure the picture is placed correctly in its cell and calculates the bottom-right position properly. This step "fixes" any confusion about the picture's position.

Why does scaling (resize(double scaleX, double scaleY)) work after that? Once the picture has a correct starting position and bottom-right corner, the scaling logic has the right reference points to resize the picture.
