Hello all;

This is as image and basic movie viewer. it can enlarge or reduce the size of the pictures and movies. It can rotate only pictures to the right or left. You can also make full screen.The Contex menu is available in the menu itself, but you can add your own.

I added an example; its very simple and clear.

Nice. I will study the right click function which was something I wanted to do.
I realise it is a demo, but the Left and Right image buttons only go one way.
Thanks for sharing.

Thank you @Peter Meares ;
My lib has a bug. it's default value of rotate left &right is same.
For you, quick solution is you can load by manuel context menu .
Sample sub is :
B4X:
private Sub Context_Menu_load
'.....
I uploaded new sample. See #1 article.


And You can try directly like under below

B4X:
 z.Text="Rotate Left"
    z.CM_Type=jPictureBox1.CM_Type_Function
    z.CM_Rate=jPictureBox1.CM_Rate_Rotate_CCW


  z.Text="Rotate Right"
    z.CM_Type=jPictureBox1.CM_Type_Function
    z.CM_Rate=jPictureBox1.CM_Rate_Rotate_CW

in this week; I will release new version, I will fixed bug and it has video support.

Hi,
first of all, thanks for your library! Currently i try to find out, if i can use it for my needs. So i come to my first problem: i want to translate the context menus. I tried to find out with your sample; you have used "PRINTER" and "PRINT" in Context_Menu_load, but i never find this words in any context menu. For me, i see always the same menus. What to i make wrong?
