Hi Tim,

I added a 679KB background jpg image to tsurface.wbi.  When the library is compiled tsurface.wbi blows out to over 10MB.

Is there something I can do to make it smaller, besides not including the image.

EWB 2.03 B1

Thanks.

The easiest way to deal with this is to just assign the image at runtime.  You can do so before the form creation in the application program source:

Application.Surface.Background.Image.Name:='http://www.mysite.com/myimage.jpg';

In general, you should try to keep embedded background images as small as possible, and anything large should be included in the Project Manager as an external file that is bundled with the application.

Perfect!  Thanks Tim!!

Tim,

What if mainform background could be different than the other forms
backgrounds?

Like:

Background.jpg for mainform and background2.jpg for all other forms.
Also would following work?:

Application.Surface.Background.Image.Name:='background.jpg'; //
background.jpg are present in output folder.

I have started using png files for background images, but later decided
to use jpg files because of the size of html file, but compressed html
file did not change much after changing to jpg as i expected?

Hüseyin

Sure, each control (actually, each UI element) in EWB can have a different background, just like with HTML/CSS.

<< Application.Surface.Background.Image.Name:='background.jpg'; //

Yes, that will work.

Are you specifying the background image at design-time or run-time ?  If the latter (run-time), then the background image won't be included in the HTML.  A background image is only embedded in the HTML loader if you specify it at design-time.

Tim,

Ok, so..

Application.Surface.Background.Image.Name is not a global setting - but exists for earch form created?
Currently i am specifying background images at design-time, not in runtime. If above works i could set it in runtime in forms oncreate event.

Thanks.

Hüseyin,

That's not what you asked.  You asked if the main form's background image could be different from other forms.

Do you want to change the background image of each form, or do you want to change the background image of the *entire application* (Application.Surface) whenever a specific form is active ?

Tim,

Sorry if my question was not clear. What I want is:

Mainform -> background.image('logon.jpg');
All other forms -> background.image('background.jpg');

Hope it's more clear now

Hüseyin

You can do that with the form directly by using "background.image.name"

for example in the form OnCreate :

procedure TForm1.Form1Create(Sender: TObject);
begin
   self.background.image.name := self.name + '.jpg';
end;


Application.Surface.Background is for the application itself (not form)
so you do not need to touch that at all.

Raul,

Thanks for the input
