Nah, morphic works. What you do is have it write to a canvas big enough to
hold the drawing, then get the form under it, and then save that out. So,
something like this in the morph:
asForm
| canvas |
canvas := FormCanvas extent: self extent.
self drawOn: canvas.
^canvas contentsOfArea: bounds
and write it out with:
PNGReadWriter putForm: morph asForm onFileNamed: 'someFileName.png'
I've used this with rediculously large diagrams before.

It does not work for large pictures. Consider the following:
| b |
b := RTMondrianViewBuilder new.
b shape rectangle
withBorder;
width: [ :cls | cls numberOfVariables * 5];
height: #numberOfMethods;
linearFillColor: #numberOfLinesOfCode within: RTObject withAllSubclasses.
b nodes: (Object withAllSubclasses copyFrom: 1 to: 3000).
b edgesFrom: #superclass.
b treeLayout.
b build.
^ b view
Nothing gets on the disk when you save :-(
this may be an issue with cairo rending on a (really) big surface.
I bet you won't be able to render that big images with morphic.
(morphic only renders/exports the visible part).
Jan B. sent me a morphic based exporter.

Hi Doru!
I have reviewer & improved the PNG exporter. I have tried it in my
different situation, it seems to work well.
I have taken the decision to __not__ render fixed trachel shapes. I think
this is okay in most of the cases we will face.
Let me know!
Cheers,
Alexandre

Hi Alex,
Could you please review the code in RTPNGExporter? We still get a little
problem when exporting because it seems that there is a bit of clipping
happening on the bottom and to the right.
Cheers,
Doru
