INT blendop_new()

Creates a new blending table. This table will contain a blending effect, which you'll have to set after creating the blending table. When that is done you can finally apply the blendop to a graphic.

Returns

0	- Error: insufficient memory
!0	- Success (pointer to the blendop table).

Notes

The right order of doing blending stuff: First create a new table with blendop_new(), then put a blending effect in it with for example blendop_tint(), and then assign it to a graphic with blendop_assign().

Errors

Insufficient memory

- There is insufficient memory available. This error doesn't occur often.

Example

Program test;
Private
    My_graphic;
    Blending_operation;
Begin
    Set_mode(320,240,16);
    Dump_type = complete_dump;

    x=160;
    y=120;

    My_graphic=new_map(100,100,16);
    Map_clear(0,My_graphic,RGB(255,255,255));

    graph=My_graphic;

    Loop
        If (key(_space))
            Blending_operation=Blendop_new();
            Blendop_tint(Blending_operation,1,255,0,0);
            Blendop_assign(0,My_graphic,Blending_operation);
        End
        Frame;
    End
End

Used in example: set_mode(), new_map(), map_clear(), key(), blendop_tint(), blendop_assign(), dump modes

This will result in something like:
