MapImage

The MapImage was developed to be a Delphi-component. TMapImage descends from TImage.

The added properties / functions are : - map : tstrings the description strings of the TMI's regions. the syntax for each string: first character : 'r' for a rectangular region 'c' for a round region 'p' for a polygonal region the further contents: ',xxx' for each number 'c' : 3 items (x,y,radius) (e.g. 'c,0,0,100') 'r' : 4 items (left,top,right,bottom) (eg 'r,0,0,80,120') 'p' : 2..500 items (two for each border-point (x,y)) (eg. 'p,50,0,0,100,100,100' for a triangle) if there are 2 or more regions on one point, the region described in the map with the higher index is used.

- getmap (x,y:integer) : integer on which region is the coordinate(x,y) ? result : -1 for no region xx for the index[xx] of the map-tstrings

- MapCursor,NoMapCursor : tcursor the cursor that will be shown if the mouse is / is not on a region (by default : crHand (included index : 39) / crdefault

- createregion (x:integer) : hrgn this function will create a windows-region from map[x] and give back the handle. you have to delete the region after the usage with deleteobject (result) by yourself! overlapping regions will be handled correctly.
