TCPDF Page Margin Issue
提问by Revenant
I'm creating PDF files with PHP using TCPDF. I have a small problem with created PDF files. I would like to set up right and left margin of each PDF file created. Currently if there is 10px margin on the left side, there is 20px margin on the right side.
我正在使用 TCPDF 用 PHP 创建 PDF 文件。我对创建的 PDF 文件有一个小问题。我想设置创建的每个 PDF 文件的左右边距。目前如果左边有10px的边距，右边有20px的边距。
How do I set up right and left page margin?
如何设置左右页边距？

$pdf->SetMargins(10, 10, -50, true);并$pdf->SetRightMargin(-50);没有任何的运气。

In the new documentationit shows the function as
在新文档中，它将函数显示为
TCPDF::SetMargins($left,$top,$right = -1,$keepmargins = false)
TCPDF::SetMargins($left,$top,$right = -1,$keepmargins = false)
And describes the parameters as:
并将参数描述为：
Parameters:
$left (float) Left margin. $top (float) Top margin. $right (float) Right margin. Default value is the left one. $keepmargins (boolean) if true overwrites the default page margins
参数：
$left (float) Left margin. $top (float) Top margin. $right (float) Right margin. Default value is the left one. $keepmargins (boolean) if true overwrites the default page margins
So, for the right margin a -1is used to indicate that no right margin was supplied and to use the same as the left margin. You were using -50which is not a valid margin.
因此，对于右边距，a-1用于表示没有提供右边距，并使用与左边距相同的值。您使用的-50是无效保证金。
Try this instead:
试试这个：
$pdf->SetMargins(10, 10, 10, true);
