how to programmatically export a png with roassal?

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

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 ]

Hi,

I am trying to find a way to obtain a bitmap programmatically with a Roassal visualization. I try this:

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
