For EyeSee diagrams, this is already present (if you just want the chart
and not the browser). From the browser, there is the menu Export that will
export to GIF or PNG.
If you want the chart without opening the browser, it is already ready to
be used as well. It's not directly available from the UI, but then this is
working around the UI, so to speak:
<bunch of chart setup, right up to just prior to chart open>
image := ReadWriteStream on: (ByteArray new: 1024).
PNGReadWriter putForm: chart canvas imageForm onStream: image.
^image
"That will return a PNG bytes, useful for instance if you are displaying it
on the web, or putting it into a document"
Or, if you want to save the chart immediately to the file system:
<bunch of chart setup, right up to just prior to chart open>
image := FileStream newFileNamed: 'chart.gif'.
image binary.
GIFReadWriter putForm: chart canvas imageForm onStream: image.
image close.

Tx Doru.
My request actually was about a "formal" mechanism where we could generate
screenshots from Glamour browsers and later integrating them in the pdf
documents, for example.
Now, most of the time what we to export are roassal visualizations or
Eyesee diagrams. Roassal come with its own support and eyesee has its
canvas in the presentation that be exported. So added an extension method
on GLMEyeseePres to be able to export the canvas as a PNG.
My hack for the morphs is to do the rendering of the morph and then obtain
a ImageForm to be exported. So I think even with the morphs it wont be too
difficult to create something that works reasonably well. For the moment, I
kept these into my extension methods on Glamour but if its something that
can serve to the community I can share a slice to be integrated into
Glamour.

Usman

Hi Usman,
Sorry for the late reply.
Interesting request.
The only way you can do that is to obtain a reference to the Morph
corresponding to your presentation, and this can be tricky. The problem is
that not all generated morphs have the same internal representation, and it
is difficult to have a general solution.
However, if you are looking only for a practical manual solution, you can
do this:
- open your browser and bring it in the desired constellation
- on the window title bar do: Ctrl+Shift+RightClick
- on the menu do explore
- in the GTInspector that opens, choose the Submorphs tab
- start selecting nodes
- in the pane to the right, choose the Morph tab and you will get a
preview of what is selected
- continue selecting from the left pane until you get to the desired morph
- from the right pane, choose the top right menu and export to PNG
Here is a description including a video:

Did someone try to export individual panes of a
glamour browser to an
image file?
I see that GLMBrowser>>screenshot:
aFilenameString on: anObject after:
aBlock
does an export of the browser window's image
but that more than what I
am looking for.

Usman
