==============

Hi,

As all of you know the Image class in Dynamics Ax 4.0 and 2009 can only run on client. This poses a problem when you want to print for example invoices with your company logo on it. Having this found out I went to look for an alternative!

I’ve added this code to the top of the PDFViewer class in the writeBitmap(OutputBitmapField _field, OuputSection _section) method

if( isRunningOnServer() &&
    _field.name()       == #FieldLogo)
{
    this.BLOGWriteBitmapOnServer(_field,_section);
    super(_field, _section);
    return;
}

For the method BLOGWriteBitmapOnServer(OutputBitmapField _field, OuputSection _section) I have copied everything from the writeBitmap and started by replacing the Image object with a System.Drawing.Image object, you can make a company parameter for this file path.

img = System.Drawing.Image::FromFile(imgStr);

After compiling there are a few errors witch I’ve corrected and ended up with this code.

public void BLOGWriteBitmapOnServer(OutputBitmapField _field, OuputSection _section)
{
    #File
    BinData bin = new BinData();
    //Image img;
    container data, imgInfoData;
    str s;
    real x1,x2, y1,y2;
    Struct br;
    int imageObjectNo = 0;
    int newwidth, newheight;
    real pdfPreviewScale = 0.8;
    boolean generateXImage = false;
    container c;
    str fn;
    FileIOPermission writePermission;
    FileIOPermission readPermission;
    boolean grayScale = false;
 
    System.Drawing.Image    img;
    str                     imgStr;
    int                     widthTemp, heightTemp;
    CompanyInfo             companyInfo = companyInfo::find();
    ;
 
    new InteropPermission(InteropKind::ClrInterop).assert();
 
    imgStr  = companyInfo.BLOGCompanyLogoFile;
 
    br = this.boundingRectTwips(currentPage, _section, _field);
 
    x1 = br.value('x1'); y1 = br.value('y1');
    x2 = br.value('x2'); y2 = br.value('y2');
 
    if (_field.type() == 10) // resourceId, DB_RESId
    {
        //img = new Image(_field.resourceId());
        img = System.Drawing.Image::FromFile(imgStr);
 
        if (resourceIdImageMap.exists(_field.resourceId()))
            imageObjectNo = resourceIdImageMap.lookup(_field.resourceId());
        else
        {
            imageObjectNo = this.nextObjectNo();
            resourceIdImageMap.insert(_field.resourceId(), imageObjectNo);
            generateXImage = true;
        }
 
        if (debugLevel >= 1)
            info ('Image in resource ' + int2str(_field.resourceId()));
    }
    else if (_field.type() == 7) // queue

        c = _field.value();
        if (c)

        s += 'Q\n';

    }
 
    CodeAccessPermission::revertAssert();
}

This could probably been done much cleaner, but it does the job.
