Manually editing area coordinates. Is it possible?

Hi,

Currently there isn’t any existing feature for this. But if you’re familiar with WordPress development you can find them using following function:

get_post_meta([POST_ID], ‘coords’)

The coordinates are saved in post_meta in HTML image map coordinate format (“x1, y1, x2, y2, x3, y3” and so on).

If you are familiar with plugin development, it shouldn’t be too hard to write a plugin which allows you to do this.

And sorry for a late answer. :<

Spike, thanks for producing this plugin, I think it can be quite useful.

Unfortunately, I don’t actually understand the get_post_meta instruction above. Where are the area coordinates stored by the plugin, and is it possible (if the nomenclature is accurately replicated) to simply input a list of coordinates as “areas” so that the map will work properly (i.e. in the plugin editor)?

Thanks for your help!

Although your post is quite old, maybe this helps:
If you want to achieve proper rectangles, you could add the following code into image_mapper_admin_script.js in Function AddArea() just after the ‘if(Coords.length < 3) {…}’ command.

Hope this helps,
Thorsten

[ Moderator note: please wrap code in backticks or use the code button. ]

if (Coords.length == 4 && confirm('Do you want the coordinates to be adjusted as rectangles ?')) {

		topp = 10000;
		left = 10000;
		right = -100;
		bottom = -100;

		for (var i=0; i<Coords.length; i++) {

			if (Coords[i].x > right)
				right = Coords[i].x;

			if (Coords[i].x < left)
				left = Coords[i].x;

			if (Coords[i].y > bottom)
				bottom = Coords[i].y;

			if (Coords[i].y < topp)
				topp = Coords[i].y

		}

		Coords[0].x = left;
		Coords[0].y = bottom;

		Coords[1].x = left;
		Coords[1].y = topp;

		Coords[2].x = right;
		Coords[2].y = topp;

		Coords[3].x = right;
		Coords[3].y = bottom;

	}

Hi Thorsten, do you know what the difference would be if using polygons as opposed to rectangles?
