Pixmaps and performance-LibGdx

Question

In my game,I am planning to use Pixmap for drawing rectangle.Game logic is based on changing the size,angle,position etc of this rectangle object in a dynamic way. Will Pixmap create any performance issues to the android game when I use it to implement the main game logic?

I have to change the properties of the rectangle object created by the pixmap frequently .Then how it will affect the entire game performance? Do I have to find some other way to implement my requirements?Is it worth using Pixmaps ?

How it will differ if use sprite scale and rotation etc to manipulate image instead of using Pixmap?

create texture by pixmap then create Sprite with using that texture and do manipulation. Manipulation on Pixmap are quite heavy. — Abhishek Aryan, Feb 09 '17 at 07:38
So,using sprite manipulation is better than pixmap manipulation? — Niranjana, Feb 09 '17 at 07:42
ya sure. Pixmap stores its data in native heap memory. It is mandatory to use Pixmap with care, otherwise memory leaks will result. — Abhishek Aryan, Feb 09 '17 at 07:45
OK.Then hope I can avoid using pixmap and proceed with sprite.Thank you! — Niranjana, Feb 09 '17 at 07:50

According to your requirement As I think you have number of Rectangle. So create number of Sprite because one texture can be shared with number of Sprite.

Create one Texture and share with all of your Sprite(Rectangular object). Do your required manipulation on Sprite like color, size, rotation, scale.

And keep in mind :-

As a Pixmap resides in native heap memory it must be disposed of by calling dispose() when no longer needed to prevent memory leaks.

This is the explanation of what I want to do exactly.[stackoverflow.com/questions/41936007/dynamic-length-increment-of-an-object-libgdx] – Niranjana Feb 09 '17 at 08:36
there I prefer scaling or resizing or object(Sprite) rather than creation of number of Sprite. Creation of new object is very painful unless there is no other alternate. – Abhishek Aryan Feb 09 '17 at 08:48
