<p>This document introduces to the Image Processor library. </p>

<section><title>Purpose</title> <p>Image Processor is specially developed

for imaging on mobile devices. The main objective is to create powerful applications: </p> <ul>

<li><p>Photo editors </p> </li>

<li><p>Viewers </p> </li>

<li><p>Cameras. </p> </li>

<section><title>Architectural relationship</title> <p>Image Processor is designed

with hardware constraints often associated with mobile devices in mind. The

Image Processor framework minimizes both memory consumption and the CPU power

required. </p> <p>The diagrammatic representation of the Image Processor library

is as follows: </p> <fig id="GUID-BD94B563-020A-4E81-808A-6A5C04AF74B9">

<section><title>Image Processor</title> <p>Image Processor is a high-level

library and framework. Image Processor encapsulates all the internal processing

and basic functionality required to create applications. Basic functions include </p> <ul>

<li><p>initiate image processing </p> </li>

<li><p>decode images </p> </li>

<li><p>zoom images </p> </li>

<li><p>pan images </p> </li>

<li><p>render images to screen or file. </p> </li>

</ul> <p>The Image Processor library also allows some geometrical operations

to the image: </p> <ul>

<li><p>rotate or flip </p> </li>

<li><p>crop. </p> </li>

</ul> <p>Optionally, the Image Processor library supports </p> <ul>

<li><p>effects </p> </li>

<li><p>overlays. </p> </li>

</ul> </section>

<section><title>Image Processor Adaptation Plug-in</title><p>The Image Processor

adaptation plug-in is an attachable component which implements the features

of the Image Processor library. The Image Processor adaptation plug-ins are

dependant on the Image Processor library, and will not function as standalone

components. </p> <p> <b>Note: You must write your own Image Processor adaptation

plug-in, because the Image Processor adaptation plug-in is not provided.</b> </p></section>

<section><title>Key Image Processor Class</title> <p>The principal classes

of the Image Processor library are as follows: </p> <ul>

<li><p> <xref href="GUID-9E5136D1-B8BE-3CE4-9A20-39D672E31EC7.dita#GUID-9E5136D1-B8BE-3CE4-9A20-39D672E31EC7/GUID-13E30312-DD05-3581-9A59-C3569A981657"><apiname>ImageProcessor::CImgProcessor</apiname></xref>, which provides a

convenient interface to process images. </p> </li>

<li><p> <xref href="GUID-9E5136D1-B8BE-3CE4-9A20-39D672E31EC7.dita#GUID-9E5136D1-B8BE-3CE4-9A20-39D672E31EC7/GUID-5DD1A7CA-B0F8-3769-9D53-4541BDC2C3FB"><apiname>ImageProcessor::TEffect</apiname></xref>, which is the parent class

of all effects, for example, <xref href="GUID-9E5136D1-B8BE-3CE4-9A20-39D672E31EC7.dita#GUID-9E5136D1-B8BE-3CE4-9A20-39D672E31EC7/GUID-6703666E-4B7E-3AD2-A03F-A6B7D2F8AD02"><apiname>ImageProcessor::TEffectAntique</apiname></xref>. </p> </li>

</ul> </section>

<section><title>Using Image Processor</title> <p>Image Processor is used for

the following: </p> <ul>

<li><p>To initialize and process an input image </p> </li>

<li><p>To apply effects and filters to the image. </p> </li>

<li><p>Overlay images onto an image. </p> </li>

<li><p>To render a low resolution preview of the image for display on screen. </p> </li>

<li><p>To render a high resolution compressed image to disk or memory. </p> </li>

</ul> </section>
