TImageViewer or equivalent

[Dzandaa]

Hi everybody,

Working with Lazarus Pascal 2.012 FPC 2.3.0 on Windows, Linux and MacOS

I am looking for a control or code for zoom and pan a BGRA image.
An equivalent to Delphi TImageViewer.

Thank you.

Hi!

For your needs there is the component

BGRAImageManipulation

In the tab BGRA Controls.

Hi,

BGRAImageManipulation is not really what I want, thank you anyway.

I already tested ATImageBox,
It's close to what I need, but I had some refreshing problems panning with the mouse
when zoom is out (see attachment).


I have a TBGRABitmap called Picture, and for the moment, I show it on a TImage without pan and zoom.

Hi!

The BGRAbitmap has a lot of features like

* zoom
* rotate
* GetPart

So it's just some lines of code.

Hi,

I know BGRA has a lot of features and I've been using it for quite some time

What I'm looking to find out is if there is already a tool that allows you to do Pan and Zoom without rewriting all the code.

What most closely resembles what I'm looking for is ATImageBox.
