EXCEPTION_ACCESS_VIOLATION (0xc0000005) from function "ToIntArray" while using CreateColorImageMappedToDepth

[nadiya_s_]

Hi,

I am using R200 camera and java is the programming language.

I am getting both color and depth image data and able to save that data and also able to recreate the image,But while i am trying to get the mapped color image to depth i am getting ERROR .

i am using CreateColorImageMappedToDepth and getting ERROR while trying to get the integer array via using mappedData.ToIntArray(0, mBuff);

Same code was working F200

CodeSnippet:-

    PXCMCapture.Sample sample = senseMgr.QuerySample();
                    if ((sample.color != null)&(sample.depth != null))
                    {   
                           PXCMImage depth= sample.depth;
                        PXCMImage color= sample.color;
                        PXCMProjection projection=device.CreateProjection();// Create the PXCMProjection instance.             
                        PXCMImage mappedColorImage=projection.CreateColorImageMappedToDepth(depth,color); 
                        System.out.println(mappedColorImage.QueryInfo().format);
                        System.out.println(mappedColorImage.QueryInfo().height);
                        System.out.println(mappedColorImage.QueryInfo().width);
                        PXCMImage.ImageData mappedData = new PXCMImage.ImageData(); 
                        sts = mappedColorImage.AcquireAccess(PXCMImage.Access.ACCESS_READ,PXCMImage.PixelFormat.PIXEL_FORMAT_RGB32, mappedData);
                          if (sts.compareTo(pxcmStatus.PXCM_STATUS_NO_ERROR) < 0)
                        {
                           System.out.println ("Failed to mapped  color data with depth");
                          System.exit(3);
                        }    
                          
                          int mBuff[] = new int [mappedData.pitches[0]/4 * cHeight];
                          mappedData.ToIntArray(0, mBuff); //ERROR on this line   
                          
                          m_df.image.setRGB(0, 0, cWidth, cHeight, mBuff, 0, mappedData.pitches[0]/4);
                          m_df.repaint();

I'm using C# so it may be different to the Java implementation but I do it this way (working with both F200 & R200):

var mwidth = mappedImage.info.width;
var mheight = mappedImage.info.height;
mappedPixels = mdata.ToShortArray(0, mwidth * mheight);

Maybe your mBuff variable is wrong?
