JavaScript drag and pull zoom effect

Updated: December 10, 2008 17:45:02 Author:

Drag and zoom effect to adjust the area (width and height) of the layer by dragging the mouse. For example, the marquee effect.

The drag and pull scaling here is a little more complicated than the general marquee selection. It can set fixed trigger points in eight directions (directions), and can set the minimum range, maximum range and scale.
Like the drag-and-drop effect, the prototype of the program is also made when the image cutting effect is made. But there are many references to this effect. Basically, I have been exploring myself and took many detours. Now I have finally made the effect I want. The comparison between the program and the previous version has been "unrecognized". I still feel that there are many things that need improvement, just like there will never be the most perfect Turkish carpet.
There is also a simplified version of SimpleResize, which is easy to learn.

ps: The instance contains drag and drop effects, but the two effects are completely independent, and the drag and drop parts can be scaled normally.
