Miss the possibility to place and scale a picture only by using the two top corners of a picture

M.E shared this idea 4 years ago

Declined

Now and then I want to use two points to draw/scale a picture from and use the same points for pictures of different size so that it's easy to move them all around just by moving one of the points (as the other just has a certain distance from the other point).

To make a nice layout and be sure that a picture isn't overlapping other objects or that there suddenly is to much space between a picture and other objects, it would be nice if it was possible also to place and scale a picture only by using the two corners in the top of the picture.

I like this idea

Maybe you mean something like in the attachment (command PointIn)?

(with the movable 2 corners A and B in the bottom of picture)

Thank you for your suggestion.

Maybe it's me who can't see it or maybe I haven't made my self clear. But I can't see that it is possible in your applet to place and scale the picture by using only the top two corners of the image. As you mention; you use the lower two corners.

For me it's just look like that you have made an example of how to move a picture around by only moving one point. But if so, it seems to be a bit complicated way to do it. I do the same just by enter a specific distance between the two lower corners of the image and add this to the x-coordinate of the lower left corner to get the x-coordinate of the lower right corner. And I define the y-coordinate of the lower right corner as the same as for the lower left corner. So I assume that there is more in to it than that. But I can't see it...

Check the definition of point B.

Check points E and F as you move B.

create an example to make it clearer.

----------------------------------------

explain what a "picture" is.

(something like a photo or points in an area or both or something else)

----------------------------------------

explain why the 2 points must by in the top (and why the bottom points are not useful)

If you drag and drop a pixle-picture from outside in the graphic, then GGB create 2 points.

This are in the bottom of the pixle-picture and with this 2 points you can scale, rotate and move the picture.

What is not useful?

You can translate the image to achieve that (and hide the original)

I'm not sure I follow you.

What do you mean by "translate" ?
