Definition

INT map_xput ( <INT fileID> , <INT destinationGraphID> , <INT originGraphID> , <INT x> , <INT y> , <INT angle> , <INT size> , <INT blitflags> )

Draws (blits) a graph onto another graph.

If the advanced parameters aren't needed, map_put() can be used. If a graph from one file needs to be drawn onto another graph in a different file, or a separate width and height scaling is needed, map_xputnp() can be used.

Parameters

INT fileID - The file that holds the graphs.
INT destinationGraphID - The graph to draw on.
INT originGraphID - The graph to draw with.
INT x - Where on the destination graph's x-axis to put the graph.
INT y - Where on the destination graph's y-axis to put the graph.
INT angle - What angle to draw the graph at.
INT size - What size to draw the graph at.
INT blitflags - What blit flags to draw the graph with.

Returns

INT : true

Notes

The x and y parameters denote where to draw the graph, that is, where the center of the to be drawn graph will be. Blit flags can be used to give the drawing (blitting) a special effect.

When angle is 0 and size is 100, the speed is greater, because the graph doesn't need rotating or scaling.

Errors

Unsupported color depth - The origin graph's color depth is greater than the destination graph's.

Example 

Program watskeburt;
Global
    destgraph;
    origgraph;
Begin

    // Set the mode to 16bit and some resolution
    set_mode(320,200,16);

    // Makes the destination graphic a red square
    destgraph=new_map(100,100,16);
    map_clear(0,destgraph,rgb(255,0,0));

    // Makes the origin graphic a blue square
    origgraph=new_map(100,100,16);
    map_clear(0,origgraph,rgb(0,0,255));

    // Draws the blue square on the center of the red square transparently, at a random angle and a random size
    map_xput(0,destgraph,origgraph,50,50,rand(-180000,180000),rand(50,150),4);
    map_xput(0,destgraph,origgraph,50,50,rand(-180000,180000),rand(50,150),4);

    // Shows the final graph
    put(0,destgraph,160,100);

    Loop
         frame;
    End
End

Used in example: set_mode(), new_map(), map_clear(), put()
