[решено] System.Drawing2D при изменение размера изображения получается полупрозрачный край

[Vandheer]

Привет. При изменении размера изображения средствами System.Drawing.Drawing2D на выходе у изображения получается полупрозрачный край в толщину в 1 пиксель. Как не допустить появления этой кромки?
