Morphic component to display images/pictures

Hi,

do we have a Morphic/Brick/whatever component for displaying pictures/images in Pharo?

The "best" I found was GTInspector extension on PNG files, which provides scrollbars, however I would like to also have:

1) zooming with mousewheel (now it scrolls vertically)
2) dragging the image around to scroll both vertically and horizontally (now I have to use manually the scrollbars)
3) ideally also buttons like "show 1:1 size", "show fit to window"

Do we have something like that?

Thanks,
Peter

You can combine something with ImageMorph, ImagePreviewMorph, Form and
TransformMorph. I don't know about mousewheel support, I vaguely
remember something about mousewheel events being tranformed, and
forgot if that was vm- or image-side.

Just by curiosity: can it be done with Spec ?

The mooc challenge (no #4) doesn't really address any of the things I am interested in (the result is the same as what inspector can currently do).

Spec has ImageModel, but that doesn't even have scrollbars...

anyway... I am currently refactoring Spec interpreter and after that I would like to improve some things... so maybe I could improve the ImageModel, since we don't have what I want...

Re: Morphic component to display images/pictures

Cool (for the interpreter refactoring). Let us know when you have something.

I thought that you wanted to display an image.
