an image on the screen</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>The Symbian Image Converter Library (ICL) supports the decoding of image

files. You can use the ICL architecture to load an image stored in a file

or a descriptor and convert it to a <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Font_and_Bitmap_Server/CFbsBitmapClass.html" format="application/java-archive"><codeph>CFbsBitmap</codeph></xref> object.

Use this bitmap object, for example, to display the image on the screen of

the mobile device after the capture.</p>

<p>For a reference example, see <xref href="http://www.forum.nokia.com/info/sw.nokia.com/id/567330dd-130f-4f1d-9380-fac5aec5a6a9/S60_Platform_Image_Converter_Example.html" scope="external">S60 Platform: Image Converter Example</xref> on Forum Nokia.</p>
