if (!_itemId) return inventImages.ItemImage; // Return null bitmap. The whole AX client crashes if you try to do the resizing code below on a null bitmap.
select firstonly inventImages where inventImages.ItemId==_itemId;
//return inventImages.ItemImage; // Would normally just do this, but see comments below.
// Ok, this next bit is weird!
// There is a known issue with AX reports with images in, getting saved as PDFs:
// In some cases, the images appear as garbage on the PDF.
// I have found that resizing the image before rendering it, causes the image to come out ok on the PDF.
// So the code below does a token resize (by 1.0 times!) operation on the image before returning it.
// That is enough to make the image on the PDF turn out ok.
image=new Image(inventImages.ItemImage);
image.resize(image.width()*1.0,image.height()*1.0,InterpolationMode::InterpolationModeHighQuality);
return image.getData();
