Instead of hardcoding screen size, i will suggest you to resize image accordingly screen resolution. Check CBitmapScaler API in DOC.

Also check this article in wiki.

thanks for your quick reply.

but suppose i have long image then it will not display properly so that i need to Scroll
what you suggest me about that ?

Currently i am using 360 X 640 Image Size but my about us image size too long.

If you dont want to resize image than you have to implement your own logic for adding scrollbar.

Even if you want to hardcode sizes, you should simply check it in runtime once (and log/display it). Knowing the size, you could create a properly sized image for the given device then.

Hi savaj,

[savaj]

AFAIK no such example is available.

i am trying to impliment that resize code into my project but i could not able to Create object of ImageResizer Class

i have follow below steps:
- Add ImageResizer.h
- Add ImageResizer.cpp
- Added 2 Library

and trying to create object of ImageResizer class in my UI.CpP Class it will gives me error

iImageResizer = new (ELeave) CImageResizer(this);

Errors:

(1) function call '[CImageResizer].CImageResizer({lval} CTAppUi *)' does not match
(2) 'CImageResizer::CImageResizer(MImageResizerObserver *)'
(3) 'CImageResizer::CImageResizer(const CImageResizer &)'

Have you derived your Ui class form MImageResizerObserver ??? You have to implement observer MImageResizerObserver, and override its method ResizeComplete().

[skumar_rao]

you forgot to derive your AppUi class from MImageResizerObserver.

you forgot to derive your AppUi class from MImageResizerObserver.

I am trying to derive this [MImageResizerObserver] class in my UI but i am getting the below error:
illegal use of abstract class ('MImageResizerObserver::ResizeComplete(const int &)')

My code:

class CTAppUi : public CAknAppUi, MImageResizerObserver
{
public:
CImageResizer* iImageResizer;
}

Have you implemented its pure virtual function in your CTAppUi ???

Its look like you have not readed all reply carefully.

Thanks for your support.

Sorry for my miss communication but i am new in the symbian so where i am wrong i am not understand.

can u please send me here sample code if Possible:

It is hard to decide what you have now.

If you have
"class CTAppUi : public CAknAppUi, MImageResizerObserver"
you can not have
"(1) function call '[CImageResizer].CImageResizer({lval} CTAppUi *)' does not match
(2) 'CImageResizer::CImageResizer(MImageResizerObserver *)'"
because CTAppUi would be an MImageResizerObserver, thus CTAppUi* ("this") would be an MImageResizerObserver* then.

And if you have
"illegal use of abstract class ('MImageResizerObserver::ResizeComplete(const int &)')"
you have been already given the step you should do, implement the referred method.
