调研方向

从 PDFDocument.text 入口开始,复现提供的浏览器示例,重点关注使用 continued: true 和显式 x 坐标的调用。将得到的位置与第二次文本调用使用 x=0 时的预期对齐方式进行比较;当 x 和 y 坐标在连续文本流中的行为符合文档说明时,即视为完成。

描述

Bug Report

Description of the problem

What I noticed is that the x (and potentially the y coord) is not an absolute position in the text function when 'continued' is set to true
As far as I could read there is no mention of relativity of the coord-position in relation to the continuedflag, but maybe I misunderstood the API.

I know a workaround already, but I would love to know where this relativity is comming from (i.e. where does it anchor to?). As when I set x of the second text to 0 it does not line up with the first text on the same line

Code sample

// create a document and pipe to a blob
var doc = new PDFDocument();
var stream = doc.pipe(blobStream());

// this should line up both the first and second text on each line
doc.text('testing',
{
    continued: true
});
doc.text('test', 200, undefined);
doc.text('testing out',
{
    continued: true
});
doc.text('test', 200, undefined);

doc.moveDown().moveDown();

// this is a work around which I would expect with the above code
const x = doc.x
doc.text('testing', x, undefined);
doc.moveUp();
doc.text('test', 200, undefined);
doc.text('testing out', x, undefined);
doc.moveUp();
doc.text('lolz', 200, undefined);


// end and display the document in the iframe to the right
doc.end();
stream.on('finish', function() {
  iframe.src = stream.toBlobURL('application/pdf');
});
