Retrieves the height of a tile in dialog box units
(dimy_tile key)
Arguments
A string specifying the tile to be queried. The key argument is case-sensitive.
Return Values
The height of the tile.
The coordinates returned are the maximum allowed within the tile. Because coordinates are zero based, this function returns one less than the total Y dimension (Y-1). The dimx_tile and dimy_tile functions are provided for use with vector_image, fill_image, and slide_image, which require that you specify absolute tile coordinates.
Examples
(setq tile_height (dimy_tile "my_tile"))
