Scaling svg images in context pane

[lapetron]

Hello,

I want to use some svg images to be displayed in the Context Pane
(ContextPane::SwapPicture).

The images (CEikImage) are constructed from resource, the size of every pic is 32x32 px by default.

I tried several ways to scale image's size to Context Pane's size, but the
images are always displayed at its original size.

Does anyone have suggestions how to do this ?

Thanks in advance.

If you set picture through CAknContextPane::SetPictureL method, does it scale correctly?

Hello teemukurppa,

thanks for answering.

I also tried to change the icon by using CAknContextPane::SetPicture
instead of SwapPicture with same result, i.e. no correct scaling.

Ok, then there might be some problem with image that you are passing to it. Can you paste code to show how you create/load it, it might reveal the problem.

Ok, here's a code snippet of what I'm doing:

// in class AppUi
void LoadIcon()
{
CAknContextPane* contextIcon = static_cast< CAknContextPane* >
(StatusPane()->ControlL(
TUid::Uid(EEikStatusPaneUidContext ) ));
TRect imageRect;
TSize imageSize;
if(NULL != contextIcon)
{
imageRect = contextIcon->Rect();
imageSize = TSize(imageRect.Width(),imageRect.Height());
}
else
{
imageSize = TSize(64,64);
}

CFbsBitmap *bitmap, *mask;

// image is a member of AppUi
image = new(ELeave)CEikImage();
AknIconUtils::CreateIconL(bitmap,mask,
KIconPath,
EMbmIcon_aifId,
EMbmIcon_aifId_mask);
AknIconUtils::SetSize(bitmap,imageSize,EAspectRatioPreserved);
AknIconUtils::SetSize(mask,imageSize,EAspectRatioPreserved);
image->SetPicture(bitmap,mask);
if(NULL != contextIcon)
{
contextIcon->SetPicture(image);
}
}

Hope this helps.

Okay, your code seems reasonably ok, so I can't point any specific problem in it.

However, it works for me, when I load SVG icon, I set size to TSize(0,0) (I don't know if this is needed, but that's what I've in code, sounds unnecessary though), and use CAknContextPane::SetPictureL( CFbsBitmap* aBmp, CFbsBitmap* aMask).

Try it without setting size (or setting it to TSize(0,0)) and using that different variant of SetPictureL

It might be the missing viewbox-issue: http://wiki.forum.nokia.com/index.ph...wBox_attribute

Hello wizard_hu,

I searched for everything about svg-images in wiki.forum,
but could not find this article.

But this resolved all my problems.

Thank you very much for your help.

@teemukurrpa: Thanks again.
