Why doesn't my timage show up on my form?

I place a timage on a form, put an image in and run.
When the form appears at runtime, I cannot see the image!
How do i get it to show up?

----------------------------------------------------------------------

What's the image ?
And does it show at designtime ?

----------------------------------------------------------------------
DanNineOne · 2009-05-02 12:04

it is a PNG, (although I have tried BMP and JPG too, they do not work
either) I can see the image at design time but not runtime

----------------------------------------------------------------------

did you set image.visible to true ? (Silly guess maybe ?)

----------------------------------------------------------------------

Being the bright spark that I am, yes I did check the "visible"
property.

What OS?
Which Lazarus version?

Can you post a minimal example that shows the problem (preferably just
a form with one TImage withe the image you use), so we can investigate
what goes wrong?

Running on windows XP, (although I regularly compile it for linux
also) just an image on a form with this pic in it:

It works as expected (with your PNG) in lazarus 0.9.27 (r19751) / fpc
2.2.2 on Win9x.

Time for an upgrade of Lazarus perhaps?

ok, thanks for the help, i'll be upgrading to the latest version.

----------------------------------------------------------------------
DanNineOne · 2009-05-07 15:16

Just managed to get it compiled (laz 0.9.27), and i still cannot see
thie images.
I still see them at design time but not runtime.
I don't know if this will help but the image is on a tab sheet in a
tPageControl.

I don't know, but did you try to put it into a panel, maybe that can
help you.

Putting it in a panel doesn't help.

Post your sample program here, and we can see what goes wrong.

Here is a sample project (see attachment)

My 2 cents: works with Vista / Lazarus 0.9.27.

I don't see your picture but thats because application can't find
'TImagingPNG' class which stored that data.

I suspect the problem is in next:
You are using some package in the IDE which registers TImagingPNG
class for .png image format. Thus in design-time you IDE which built
with TImagingPNG can load your picture. But your application does not
include TImagingPNG class and therefore can't load stored data.

Solution:
a) remove package with TImagingPNG class from IDE and rebuild it after
b) add unit which registers TImagingPNG as a graphic format to your
uses section.

Thanks Paul, it was the vampyre imaging package that was causing the
trouble.
