[platform-swt-dev] HTML To Image tool

[Roland Auckenthaler <Roland_Auckenthaler@xxxxxxxx>]

Hi All,
Today i was writing an HTML to image
rendering tool using the SWT which works pretty well so far. I have attached
to code here too. To this little app i ahve a couple of questions which
i wasnt able to do yet.

- capturing a widget image when not
visible. When i capture the rendered HTML from the browser widget i need
to be visible. I tried to minimize the visibility to only a couple of lines
( see the capture method) but would like to be fully invisible when capturing.

- vertical scroll bar. I cannot get
rid of the vertical scroll bar when capturing at the moment i reduce the
capturing area by 18 pixels (see capture metohd) but ideally i would prefer
not to do that. Is there a way around that?

It would be nice if somebody could give
some help on these two questions.

Thanks in advance

roland
