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 TMIs 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.System requirementsDelphi 3.0
