Component for tiled or resizable graphic background?

[vfclists]

Is there some component that can give a panel or some other panel like component. sub as a page control tab,  a background bitmap that will resize, or tile itself when the panel is resized?

Does a TImage work, where Align is set to alClient and Stretch to true?

I think that will be better handled by the OnResize event if it is enabled for TImage. The important thing for me is that it remains permanently the lowest object in the Z-order, and that it can contain other objects. Is that possible?

I did what I think your doing back in the D5 days.  I found the differant objects and shapes on top of the image did not scale by the same % when I used the form resize.  I finaly just used the menu so the user could select one of 5 or so preset sizes.  I did not, however, have the "anchors" properties to help Keep the proper alinement of each control on the image so it may now be doable.

PS: if you have not tought of it yet, a loop working with the controlcount and controls[] fields can save you a lot of coding time.  If you need an example, I'll see if I can find any of those older projects

I have ported the TJanTiledPanel for tiled images to lazarus available on http://www.users.on.net/~dave.stewart/

Thanks,

I will look them all up.

I have gotten to the stage where I can implement the tiling,
If I simply repeat the image will that consume too many resources or cause Windows to run out memory or something?

I tried this and it is working well, thanks.

Are the limitations on the image format it accepts due to the TBitmap implentation? When I try to load jpeg or png images they are not accepted, only bmp images.

I run Linux and load png and jpg regularly, could be a restriction in windows?

TBitmap, as the name says, only accept bitmaps (.bmp). (only versions of lazarus prior to 0.9.24 accepted other formats)
To load jpeg or png, use a TJpegImage or TPortableNetworkGraphic respectively

You should use TPicture instead of TBitmap. It allows you to load different image formats.

Tpicture, Tbitmap, Timage, Tbitmap,...
Is there some link that compares or describes these tools?
