I am trying to render a bitmap through DirectX StretchRect. The image contains 18 * 17 (32 pixel) tiles. This image is for a tetris clone. The main game area has Vertical and Horizontal lines. The problem is while rendering on the screen the image is not comming up as the orignal bitmap one of the vertical file is missing and a Horizontal line is thicker then the orignal bitmap.
I have attached the code and images. here
