New Vectorial Graph library
« on: January 06, 2019, 01:58:14 am »
Hi. I want to share my graphic library ogEditGraf: https://github.com/t-edson/ogEditGraf
It can manage graphic objects in screen, move, resize, and zoom, using Canvas. Includes connection points to implement conectors.

Hi!
Why you not use matrix transforms? Graphics library should use it, not zoom and x_y_des

More than Graphic Library, this is an "Graphic Object Edition Engine". The graphic library, here, is a simple unit with graphic methods. The matrix transformation is expanded here with a simple formula, because is very simple. There are other library I'm creating with some different Grpahic libraries.

I don't understand the idea of this lib. Basic functions.

Just a note that there is non-english language used in many places. This makes it not approachable for most of us.

This was a personal library I developed for myself a long time ago. Later I've seen it's useful for some other people. I've traslated some part of the code. It was worse. I'll be translating more in next versions.

The idea is to be used to represent graphically some entity or data. This representation is based in objects that can be created, edited, moved or resized.

Sorry. I forgot to include the routines in the program.  I will review.

I was really thinking on share some code of ZCad and TitoCad but I don't have idea where to start. I'm lack of time and I have TitoCad some abandoned.

Can it be used to diagram UML?

Unfortunately, I didn't see a way to do it either. I've overcomplicated some simple things in the pursuit of a small gain in speed
