Hi,
I am trying to find a way to obtain a bitmap programmatically with a Roassal visualization. I try this:
| view | view := ROMondrianViewBuilder new. view nodes: (1 to: 10). view raw bitmap
The problem is that the nodes are not yet laid out. As far as I remember, this used to work.
How do I trigger the layouts easily?
Cheers, Doru
I was using
saveFileFrom: view named: aString | writeStream | writeStream := ((FileSystem workingDirectory / (aString, '.png')) writeStream. [ (ROPharoImageExporter new view: view) exportWith: PNGReadWriter onStream: writeStream ] ensure: [ writeStream ifNotNil: #close ]

Thanks, but this is not enough.
This method would work just like #bitmap would. But, before using this method the layout has to be applied first.
In the meantime, I found the method in ROMondrianViewBuilder>>#applyLayout.
So, this will work fine: | view | view := ROMondrianViewBuilder new. view nodes: (1 to: 10). view applyLayout. view raw bitmap asMorph exportAsPNG

Yes, applyLayout does the think. Maybe I can insert a call to applyLayout in bitmap.
