Detailed Description this file defines all adgali features associated vith the video functions and must be include when you use adgali agl.h includes this file Define Documentation #define AGL_SETALPHA (  value )     (agl_swapbe32(value) & AGL_ALPHA)   this function sets the alpha channel in a pixel value Parameters: value   the alpha value or this pixel (255 is opaque, 0 is transparent) Returns: the pixel value #define AGL_SETBLUE (  value )     (agl_swapbe32(value << 8) & AGL_BLUE)   this function sets the blue color in a pixel value Parameters: value   the color value is between 0 and 255 (0 is black) Returns: the pixel value #define AGL_SETGREEN (  value )     (agl_swapbe32(value << 16) & AGL_GREEN)   this function sets the green color in a pixel value Parameters: value   the color value is between 0 and 255 (0 is black) Returns: the pixel value #define AGL_SETRED (  value )     (agl_swapbe32(value<<24) & AGL_RED)   this function sets the red color in a pixel value Parameters: value   the color value is between 0 and 255 (0 is black) Returns: the pixel value #define agl_pixalpha (  psrc, pdst, psrcrect, pdstrect, pos )     agl_pixtransalpha(psrc, pdst, psrcrect, pdstrect, pos, PIX_ID)   copy one zone into another one with clipping of destination zone and source zone and apply alpha to zones if psrcrect and pdstrect are NULL, this is a real alpha copy Parameters: psrc   the source zone to copy pdst   the destination zone psrcrect   the clipping rectangle for the source zone. This rectangle defines a clipping into the source zone. The coordonates refers into the source zone pdstrect   the clipping rectangle for the destination zone. pos   the position of the source zone into the destination zone. Returns: -1 if an error occurs 0 if nothing bad appears #define agl_pixcat (  psrc, pdst, psrcrect, pdstrect, pos )     agl_pixtranscat(psrc, pdst, psrcrect, pdstrect, pos, PIX_ID)   copy one zone into another one with clipping of destination zone and source zone alpha of the destination zone is supposed to be opaque if psrcrect and pdstrect are NULL, no clipping is done alpha of original dest zone is 255 (opaque) Parameters: psrc   the source zone to copy pdst   the destination zone psrcrect   the clipping rectangle for the source zone. This rectangle defines a clipping into the source zone. The coordonates refers into the source zone pdstrect   the clipping rectangle for the destination zone. pos   the position of the source zone into the destination zone. Returns: -1 if an error occurs 0 if nothing bad appears Function Documentation int agl_pixtransalpha (  agl_pix * psrc, agl_pix * pdst, agl_rect * psrcrect, agl_rect * pdstrect, agl_pos * pos, int type )    copy one zone into another one with clipping of destination zone and source zone and apply alpha to zones if psrcrect and pdstrect are NULL, this is a real alpha copy apply transformation to source before copying to dest Parameters: psrc   the source zone to copy pdst   the destination zone psrcrect   the clipping rectangle for the source zone. This rectangle defines a clipping into the source zone. The coordonates refers into the source zone pdstrect   the clipping rectangle for the destination zone. pos   the position of the source zone into the destination zone. type   the type of copy. Returns: -1 if an error occurs 0 if nothing bad appears int agl_pixtranscat (  agl_pix * psrc, agl_pix * pdst, agl_rect * psrcrect, agl_rect * pdstrect, agl_pos * pos, int type )    copy one zone into another one with clipping of destination zone and source zone alpha of the destination zone is supposed to be opaque if psrcrect and pdstrect are NULL, no clipping is done alpha of original dest zone is 255 (opaque) apply transformation to source before copying to dest Parameters: psrc   the source zone to copy pdst   the destination zone psrcrect   the clipping rectangle for the source zone. This rectangle defines a clipping into the source zone. The coordonates refers into the source zone pdstrect   the clipping rectangle for the destination zone. pos   the position of the source zone into the destination zone. type   the type of copy.
