PDF Order Center tweak help

[brushwoodnursery]

I'm happy to say that PDF Order Center works fine in 1.3.8a and I'm using it for packing slips with success. I'm hoping someone with experience can help me tweak one small item in the output. I'd like to format the product lines so they are easier to read across. Right now the background is all light grey. I'd like it to alternate light grey and white or to have a very thin line between each product line. Here's the code that's relevant:

  // products , model etc table layout
  PDFOC_change_color(PDFOC_TABLE_HEADER_BKGD_COLOR);
  $pdf->filledRectangle(PDFOC_LEFT_MARGIN,$pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT,PDFOC_PRODUCT_TABLE_HEADER_WIDTH,PDFOC_PRODUCT_TABLE_ROW_HEIGHT);

  $x = PDFOC_LEFT_MARGIN + PDFOC_PRODUCT_TABLE_LEFT_MARGIN;
  $pos = ($pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT) + PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;

  PDFOC_change_color(PDFOC_GENERAL_FONT_COLOR);

  $pdf->ezSetY($pos+PDFOC_PRODUCT_TABLE_ROW_HEIGHT);
  $pdf->ezText(PDFOC_TABLE_HEADING_PRODUCTS,PDFOC_TABLE_HEADER_FONT_SIZE, array('aleft'=>$x));
  $x += PDFOC_PRODUCTS_COLUMN_SIZE;
  $pdf->ezSetY($pos+PDFOC_PRODUCT_TABLE_ROW_HEIGHT);
  $pdf->ezText("Shipped        Dropped      Delayed",PDFOC_TABLE_HEADER_FONT_SIZE, array('aleft'=>$x));


  $pos -= PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;

  // Sort through the products

  for ($i = $nextproduct, $n = sizeof($order->products); $i < $n; $i++) {

    // check whether too far down page to print more products; assume enough margin
    // to account for a product with wrapped text and a couple of attributes
    //
    if ($pos < PDFOC_BOTTOM_MARGIN) {
       $secondpage = true;
       return;
    }

    $prod_str = $order->products[$i]['qty'] . " x " . $order->products[$i]['name'];

    PDFOC_change_color(PDFOC_PRODUCT_LISTING_BKGD_COLOR);
    $pdf->filledRectangle(PDFOC_LEFT_MARGIN,$pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT,PDFOC_PRODUCT_TABLE_HEADER_WIDTH,PDFOC_PRODUCT_TABLE_ROW_HEIGHT);

    $x = PDFOC_LEFT_MARGIN + PDFOC_PRODUCT_TABLE_LEFT_MARGIN;
    $pos = ($pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT) + PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;

    PDFOC_change_color(PDFOC_GENERAL_FONT_COLOR);
    $truncated_str = $pdf->addTextWrap($x,$pos,PDFOC_PRODUCTS_COLUMN_SIZE,PDFOC_TABLE_HEADER_FONT_SIZE,$prod_str);

    $pdf->ezSetY($pos+PDFOC_PRODUCT_TABLE_ROW_HEIGHT-PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN);
    $x += PDFOC_PRODUCTS_COLUMN_SIZE;
    $pdf->ezText(pdfoc_html_cleanup($order->products[$i]['model']),PDFOC_TABLE_HEADER_FONT_SIZE,array('aleft'=>$x));


    $pos -= PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;

    if ($truncated_str) {
    
    PDFOC_change_color(PDFOC_PRODUCT_LISTING_BKGD_COLOR);
    $pdf->filledRectangle(PDFOC_LEFT_MARGIN,$pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT,PDFOC_PRODUCT_TABLE_HEADER_WIDTH,PDFOC_PRODUCT_TABLE_ROW_HEIGHT);
    $pos = ($pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT) + PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;
    PDFOC_change_color(PDFOC_GENERAL_FONT_COLOR);
    $reset_x = PDFOC_LEFT_MARGIN + PDFOC_PRODUCT_TABLE_LEFT_MARGIN;
    $pdf->addText($reset_x,$pos,PDFOC_TABLE_HEADER_FONT_SIZE,$truncated_str);
    $pos -= PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;
    
    } // EOIF $truncated_str
    
    if ( ($k = sizeof($order->products[$i]['attributes'])) > 0) {

      for ($j = 0; $j < $k; $j++) {

        $attrib_string = '<i> - ' . $order->products[$i]['attributes'][$j]['option'] . ': ' . $order->products[$i]['attributes'][$j]['value'];
        
        if ($order->products[$i]['attributes'][$j]['price'] != '0') {
          $attrib_string .= ' (' . $order->products[$i]['attributes'][$j]['prefix'] .
          pdfoc_html_cleanup($currencies->format($order->products[$i]['attributes'][$j]['price'] * $order->products[$i]['qty'], true, $order->info['currency'], $order->info['currency_value'])) . ')';
        }
        
        $attrib_string .= '</i>';
      PDFOC_change_color(PDFOC_PRODUCT_LISTING_BKGD_COLOR);
      $pdf->filledRectangle(PDFOC_LEFT_MARGIN,$pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT,PDFOC_PRODUCT_TABLE_HEADER_WIDTH,PDFOC_PRODUCT_TABLE_ROW_HEIGHT);
      $pos = ($pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT) + PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;
      PDFOC_change_color(PDFOC_GENERAL_FONT_COLOR);
      $reset_x = PDFOC_LEFT_MARGIN + PDFOC_PRODUCT_TABLE_LEFT_MARGIN;

        if (PDFOC_PRODUCT_ATTRIBUTES_TEXT_WRAP) {
          $wrapped_str = $pdf->addTextWrap($reset_x,$pos,PDFOC_PRODUCTS_COLUMN_SIZE,PDFOC_PRODUCT_ATTRIBUTES_FONT_SIZE,$attrib_string);
        } else {
          $pdf->addText($reset_x,$pos,PDFOC_PRODUCT_ATTRIBUTES_FONT_SIZE,$attrib_string);
        }

        $pos -= PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;
                  
        if ($wrapped_str) {
        
        PDFOC_change_color(PDFOC_PRODUCT_LISTING_BKGD_COLOR);
        $pdf->filledRectangle(PDFOC_LEFT_MARGIN,$pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT,PDFOC_PRODUCT_TABLE_HEADER_WIDTH,PDFOC_PRODUCT_TABLE_ROW_HEIGHT);
        $pos = ($pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT) + PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;
        PDFOC_change_color(PDFOC_GENERAL_FONT_COLOR);
        $pdf->addText($reset_x,$pos,PDFOC_PRODUCT_ATTRIBUTES_FONT_SIZE,$wrapped_str);
        $pos -= PDFOC_PRODUCT_TABLE_BOTTOM_MARGIN;
        
      } // EOIF $wrapped_str
      
    } // EOFOR $j = 0
    
    } // EOIF $k = sizeof(...
    
    $nextproduct++;

  } 

Thanks for any help you can!

Nevermind. I answered my own question with some research. here's where I dropped a line in place of the background color in case anyone finds this later:

    $prod_str = $order->products[$i]['qty'] . " x " . $order->products[$i]['name'];
 $pdf->setLineStyle(0.1);  
  $pdf->line(PDFOC_LEFT_MARGIN,$pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT,PDFOC_PRODUCT_TABLE_HEADER_WIDTH,$pos-PDFOC_PRODUCT_TABLE_ROW_HEIGHT);
