void get_mapview_scroll_window	(	float *	xmin,
		float *	ymin,
		float *	xmax,
		float *	ymax,
		int *	xsize,
		int *	ysize
	)

Return the scroll dimensions of the clipping window for the mapview window.

Imagine the entire map in scroll coordinates. It is a rectangle. Now imagine the mapview "window" sliding around through this rectangle. How far can it slide? In most cases it has to be able to slide past the ends of the map rectangle so that it's capable of reaching the whole area.

This function gives constraints on how far the window is allowed to slide. xmin and ymin are the minimum values for the window origin. xsize and ysize give the scroll dimensions of the mapview window. xmax and ymax give the maximum values that the bottom/left ends of the window may reach. The constraints, therefore, are that:

get_mapview_scroll_pos(&scroll_x, &scroll_y); xmin <= scroll_x < xmax - xsize ymin <= scroll_y < ymax - ysize

This function should be used anywhere and everywhere that scrolling is constrained.

Note that scroll coordinates, not map coordinates, are used. Currently these correspond to native coordinates.

Translate from a cartesian system to the GUI system.

◆ tile_to_canvas_pos()

bool tile_to_canvas_pos	(	float *	canvas_x,
		float *	canvas_y,
		const tile *	ptile
	)

Finds the canvas coordinates for a map position.

Beside setting the results in canvas_x, canvas_y it returns whether the tile is inside the visible mapview canvas.

The result represents the upper left pixel (origin) of the bounding box of the tile. Note that in iso-view this origin is not a part of the tile itself - so to make the operation reversible you would have to call canvas_to_map_pos on the center of the tile, not the origin.

The center of a tile is defined as: { tile_to_canvas_pos(&canvas_x, &canvas_y, ptile); canvas_x += tileset_tile_width(tileset) / 2; canvas_y += tileset_tile_height(tileset) / 2; }

This pixel is one position closer to the lower right, which may be important to remember when doing some round-off operations. Other parts of the code assume tileset_tile_width(tileset) and tileset_tile_height(tileset) to be even numbers.

bool tile_visible_and_not_on_border_mapcanvas ( struct tile * ptile )

Return TRUE iff the given map position has a tile visible within the interior of the map canvas.

This information is used to determine when we need to recenter the map canvas.

The logic of this function is simple: if a tile is within 1.5 tiles of a border of the canvas and that border is not aligned with the edge of the map, then the tile is on the "border" of the map canvas.

This function is only correct for the current topology.

Update (refresh) the map canvas starting at the given tile (in map coordinates) and with the given dimensions (also in map coordinates).

In non-iso view, this is easy. In iso view, we have to use the Painter's Algorithm to draw the tiles in back first. When we draw a tile, we tell the GUI which part of the tile to draw - which is necessary unless we have an extra buffering step.

After refreshing the backing store tile-by-tile, we write the store out to the display if write_to_screen is specified.

x, y, width, and height are in map coordinates; they need not be normalized or even real.

A TILE update covers the base tile (width x height) plus a half-tile in each direction (for edge/corner graphics), making its area 2 width x 2 height.

A UNIT update covers a unit_width x unit_height area. This is centered horizontally over the tile but extends up above the tile (e.g., units in iso-view).

A CITYMAP update covers the whole citymap of a tile. This includes the citymap area itself plus an extra half-tile in each direction (for edge/corner graphics).
