Using (large) images
«
on:
March 08, 2004, 02:08:36 am »
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

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)
