Using (large) images
lazarus / 10-Designer

I'm trying to create an app that uses very large images (7.000 x
10.000 pixels) but for some reason I can't get any scrollbars to show
up so basically all I see is the upper left bit of the image.

I have copied the details from a Delphi3 app where it did work
Anything I'm overlooking here?

All help appreciated

Is it on windows or on Linux
And what control do you use

Hi,

Sorry for the omission.
I'm running SuSE Linux 9.0 with the latest Lazarus/Fpc (yesterdays
version)

Form1
   scrollbox1, -> align = alclient, autosize = true
      Image1, -> align = alclient, autosize = true

I tried :
      Form1.ScrollBox1.HorzScrollBar.Range :=
Form1.Image1.Picture.Width;
      Form1.ScrollBox1.VertScrollBar.Range :=
Form1.Image1.Picture.Height;
but as soon as I try to scroll the range of the scrollbars jumps to 0
(zero)
