Function Definition
void CP_Image_DrawSubImage(CP_Image image, float x, float y, float w, float h, float s0, float t0, float s1, float t1, int alpha);
Parameters
- image- (CP_Image) The image that you want to draw to the screen
- x- (float) The x coordinate of the image in screen coordinates
- y- (float) The y coordinate of the image in screen coordinates
- w- (float) The width to draw the image in pixels
- h- (float) The height to draw the image in pixels
- s0- (float) The left most pixel of the sub-image(far left = 0)
- t0- (float) The top most pixel of the sub-image (top = 0)
- s1- (float) The right most pixel for the sub-image (far right = image width)
- t0- (float) The bottom most pixel for the sub-image (bottom = image height)
- alpha- (int) The alpha value to draw the image with (0-255)
Return
- void- This function does not return anything
Example
CP_Image justinFace = NULL;
void init()
{
justinFace = CP_Image_Load("./Assets/Justins_face.png");
}
void update()
{
CP_Settings_Background(CP_Color_Create(255, 255, 255, 255));
int width = CP_System_GetWindowWidth();
int height = CP_System_GetWindowHeight();
int imageWidth = CP_Image_GetWidth(justinFace);
int imageHeight = CP_Image_GetHeight(justinFace);
// draws the top left quarter of the image
CP_Image_DrawSubImage(justinFace, (width / 2), (height / 2), width, height, 0, 0, imageWidth / 2, imageHeight / 2, 255);
}
void shutdown()
{
CP_Image_Free(justinFace);
}
