提问by user2000375

I am using TCPDF to generate a PDF file from HTML content. I want to set the page width and height to the custom values 400px and 300px.

我正在使用 TCPDF 从 HTML 内容生成 PDF 文件。我想将页面宽度和高度设置为自定义值 400px 和 300px。

I used the following code

我使用了以下代码

 $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

Where

在哪里

• PDF_PAGE_ORIENTATIONis p;
• PDF_UNITis mm;
• PDF_PAGE_FORMATis A6.

• PDF_PAGE_ORIENTATION是p；
• PDF_UNIT是mm；
• PDF_PAGE_FORMAT是A6。

you could do:

你可以这样做：

$custom_layout = array($your_width, $your_height);
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, $custom_layout, true, 'UTF-8', false);

Instead of PDF_PAGE_FORMAT (or A6), you could use an array to specifiy width and height.

您可以使用数组来指定宽度和高度，而不是 PDF_PAGE_FORMAT（或 A6）。

The 3rd argument of the TCPDF constructor accepts either a string like 'A4', 'A6', etc. or a two-element array containing the width and height (in the units defined in PDF_UNIT).

TCPDF 构造函数的第三个参数接受像“A4”、“A6”等这样的字符串或包含宽度和高度（在 PDF_UNIT 中定义的单位）的二元素数组。

So basically:

所以基本上：

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, array(400, 300), true, 'UTF-8', false);

If you want to define a new page by name (a completely custom page that has no relation), then this is how:

如果您想按名称定义一个新页面（一个完全自定义的没有关系的页面），那么方法如下：

1. Go to /tcpdf/include/tcpdf_static.php
2. Scroll to Line 478

3. Add your custom sized sheets in the same format

   public static function getPageSizeFromFormat($format) {
   switch (strtoupper($format)) {
       // ISO 216 A Series + 2 SIS 014711 extensions
       case 'A0' : {$pf = array( 2383.937, 3370.394); break;}
       case 'A1' : {$pf = array( 1683.780, 2383.937); break;}
       case 'A2' : {$pf = array( 1190.551, 1683.780); break;}
       case 'A3' : {$pf = array(  841.890, 1190.551); break;}
       case 'A4' : {$pf = array(  595.276,  841.890); break;}
       case 'A5' : {$pf = array(  419.528,  595.276); break;}
       case 'A6' : {$pf = array(  297.638,  419.528); break;}
   

1. 转到/tcpdf/include/tcpdf_static.php
2. 滚动到第 478 行

3. 以相同的格式添加自定义尺寸的工作表

   public static function getPageSizeFromFormat($format) {
   switch (strtoupper($format)) {
       // ISO 216 A Series + 2 SIS 014711 extensions
       case 'A0' : {$pf = array( 2383.937, 3370.394); break;}
       case 'A1' : {$pf = array( 1683.780, 2383.937); break;}
       case 'A2' : {$pf = array( 1190.551, 1683.780); break;}
       case 'A3' : {$pf = array(  841.890, 1190.551); break;}
       case 'A4' : {$pf = array(  595.276,  841.890); break;}
       case 'A5' : {$pf = array(  419.528,  595.276); break;}
       case 'A6' : {$pf = array(  297.638,  419.528); break;}
   

Just add another case with your custom size.

只需添加另一个具有您自定义尺寸的案例。

        case 'SQUARE' : {$pf = array( 297.638, 297.638); break;}
        case 'SMALLSQUARE' : {$pf = array( 100.00, 100.00); break;}

Then use the normal constructor to call the new page:

然后使用普通构造函数调用新页面：

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, 'SQUARE', true, 'UTF-8', false);
