New FPDF line height

Bruce, one suggestion might be to refactor and use TCPDF which is more actively maintained than FPDF.  But there may be a shorter path.  Can you set up a simple test that demonstrates the issue?  The less extraneous stuff we have, the better -- just some sample data, and the code that creates the PDF with the too-big lines.  I'll be glad to take a look.

FWIW, I just upgraded all my teaching examples to 1.8.1 and got no differences in line height, so I think we need to see your test cases to understand and fix.

The FPDF web site is not very HTTP and bookmark friendly, but this will help you find the Changelog.

Thanks, Ray. Will dig into the changelog tomorrow.

Attached are "before" and "after" PDFs.

We use functions to generate the different report sections.  None of our code for the report generator has changed except for the mysql_ to mysqli_ changes needed for the PHP upgrade.  Example code follows.  If you need more advise.

function ReportInfo($rpt='')
{
	global $d, $v, $pdf, $version_id;
	NewSection("Report Information", 120);
	tab();
	$pdf->Cell(75, 10, 'Ordered By:');

... initial settings for the $pdf object are out of whack ...

Bingo!  Glad you got it straightened out :-)

My scan shows these that might need to be checked.

Searching for: $pdf = new
adiBillingGenerator.php(917): $pdf = new PDF("L", "pt", "Letter");
adiReportCAInfo.php(919): $pdf = new PDF();
ajax_report_generator.php(7195): $pdf = new PDF();

Found solution on my own.
