TCPDF 页面旋转

发布于 2024-10-29 05:23:14 字数 261 浏览 2 评论 0 原文

我正在尝试生成一个PDF文件,其中包含202mm宽乘50mm的标签。我设法做到了这一点,并添加了所需的文本和条形码,但我的问题是,标签首先打印出狭窄的边缘,因此整页需要旋转90度。

我可以轻松地在Adobe阅读器中进行此操作,通过简单的右键单击页面上并选择顺时针旋转(shift+ctrl ++),但我确实需要在代码中执行此操作。

有人知道如何使用TCPDF做到这一点吗?我尝试了旋转功能,但似乎无法使其正常工作。任何代码的示例都会有所帮助。

I'm trying to generate a PDF file containing labels which are 202mm wide by 50mm heigh. I have managed to do this and added the required text and a barcode but my problem is that the labels print out narrow edge first so the whole page need rotating 90 degrees.

I can do this in Adobe Reader with ease by simple right clicking on the page and selecting Rotate Clockwise (Shift+Ctrl++) but I really need to do it in the code.

Does anyone know how to do this with TCPDF? I have tried the Rotate function but can't seem to get it working. Any examples of code would be helpful.

在构建页面时将其设置为横向怎么样?

TCPDF::__construct($orientation = 'L',
$   unit = 'mm',
$   format = 'A4',
$   unicode = true,
$   encoding = 'UTF-8',
$   diskcache = false)

$方向(字符串)页面方向。可能的值是(情况不敏感):

  • P或PROTAIT(默认)
  • L或Landscape
  • ''(空字符串)用于自动定向

http://www.tcpdf.org/doc/classTCPDF.html#a5420ac8b0726a604260780d8f4185fc1

How about setting it to landscape when building the page?

TCPDF::__construct($orientation = 'L',
$   unit = 'mm',
$   format = 'A4',
$   unicode = true,
$   encoding = 'UTF-8',
$   diskcache = false)

$orientation (string) page orientation. Possible values are (case insensitive):

  • P or Portrait (default)
  • L or Landscape
  • '' (empty string) for automatic orientation

我在 1.5 版本中所做的

    $pdf->AddPage(); // Orientation for the first page is defined into configuration file.

    $pdf->writeHTML("Portrait 1");

    $pdf->AddPage('L');

    $pdf->writeHTML("Landscape !");

    $pdf->AddPage('P');

    $pdf->writeHTML("Portrait 2");

    $pdf->Output();

工作效果很好。

What I've done with version 1.5

    $pdf->AddPage(); // Orientation for the first page is defined into configuration file.

    $pdf->writeHTML("Portrait 1");

    $pdf->AddPage('L');

    $pdf->writeHTML("Landscape !");

    $pdf->AddPage('P');

    $pdf->writeHTML("Portrait 2");

    $pdf->Output();

And this is working well.

Rotate 很奇怪。文档没有告诉您的是,您必须先执行 StartTransform,然后执行 Rotate,然后再执行 StopTransform。您只能在以某种方式设置 X/Y 位置后才能执行 StartTransform 调用(例如,我使用 SetXY 来初始定位页面,然后您可以调用 <代码>开始变换)。因此,请尝试这样做:

  $this->pdfinvoice->StartTransform();
  $this->pdfinvoice->Rotate(-90);

然后添加您的内容,然后

  $this->pdfinvoice->StopTransform();

在完成后致电。看看这对你有什么作用。

Rotate is odd. What the docs don't tell you is that you have to do a StartTransform first and then do a Rotate, then do a StopTransform afterwards. You can only do the StartTransform call after you have somehow set the X/Y position (so for example, I use SetXY to initially position the page, then you can call StartTransform). So try to do:

  $this->pdfinvoice->StartTransform();
  $this->pdfinvoice->Rotate(-90);

then add your content, then call

  $this->pdfinvoice->StopTransform();

when you're done. See how that works for you.

构造函数中的 format 参数具有多种可选参数,包括 Rotate 以及对任意页面 widthheight 的支持- 示例:

// page A4 rotated clockwise 90 deg.
$pdf = new TCPDF('L', 'pt', ['format' => 'A4', 'Rotate' => 90]); 

// page with custom size rotated clockwise 270 deg.
$pdf = new TCPDF('L', 'pt', ['format' => [$width, $height], 'Rotate' => 270]);

文档此处

The format argument in constructor has wide range of optional parameters, including Rotate and support for arbitrary page width and height - example:

// page A4 rotated clockwise 90 deg.
$pdf = new TCPDF('L', 'pt', ['format' => 'A4', 'Rotate' => 90]); 

// page with custom size rotated clockwise 270 deg.
$pdf = new TCPDF('L', 'pt', ['format' => [$width, $height], 'Rotate' => 270]);

景观最​​简单的方法是:
首先转到您的 tcpdf.config 文件
然后转到该行

 * Page orientation (P=portrait, L=landscape).
 */
define ('PDF_PAGE_ORIENTATION', 'L','P');

只需将“P”更改为“L”保存并运行它。

The simplest and easy way to Landscape is:
First go to your tcpdf.config file
then go to the line

 * Page orientation (P=portrait, L=landscape).
 */
define ('PDF_PAGE_ORIENTATION', 'L','P');

Just change the "P" to 'L' save and run it.

最简单的选项是将页面设置为横向模式“L”(如果您需要的话)。
否则,如果您需要纵向模式但具有旋转对象的页面,则可以创建 XObject 模板并将内容放在那里,包括图形转换。
检查 http://www.tcpdf.org 上的默认示例以了解图形转换和 XObject 模板。

The simplest option is to set the page on Landscape mode 'L' if this is what you need.
Otherwise, if you need a page in portrait mode but with rotated objects, then you can create an XObject template and put your content there, including graphical transformations.
Check the default examples at http://www.tcpdf.org for graphical transformations and XObject templates.

这是一篇旧文章,但如果有人遇到此问题,我建议您首先尝试该页面的横向模式。

这对我有用:

这是设置 A4 横向的代码:

$pdf->AddPage('L', 'A4');

This is an old post but if anyone has this issue, I would suggest you first try out the landscape mode for the page.

This works for me:

Here is the code for setting A4 landscape:

$pdf->AddPage('L', 'A4');
