Drawing simple vector graphics

[ErwinVJ]

Hi there, as per title of this forum, I'm a beginner and I need to find a solution for the following:

I want users to draw basic forms - limited to lines, circles and rectangles - to make a simplified visual representation of their garden. They should be able to select the forms from a menu and position the element on a 'canvas'. Each element can get a name-tag and height attribute and should be size-able in either Metric or other format.
After the element is drawn, the user should be able to move, rotate or re-size the element and enter/edit its name tag.

Some attributes that are nice to have: repositioning element using
- snap function (make vertices of the rectangles/lines snap to other vertices nearby for better alignment)
- repositioning and rotating using values instead of 'by hand'

Can I achieve this in LiveCode? Is there a tutorial, explanation, script, plugin available that I can use?

Thanks,
Erwin

Hi ErwinVJ,

Yes, you can do it with LiveCode

Is there a tutorial, explanation, script, plugin available that I can use?

I search and i'll come back

In the dictionary see the tool global property, the grid and gridSize global properties, and the rectangle object property, all controllable via script.

Note that the IDE eats some mouse-related messages when the pointer tool is the active mode, so sometimes when building a custom drawing environment you may need to suspend the IDE while testing.

Hi ErwinVJ,

I put in attachment the Carl Manaster's tangram where you can see some useful scripts for your project
and particulary to rotate polygon
