使用JavaScript在添加JSPDF上的每个新页面声明新的高度和宽度

var doc = new jsPDF('px','px', [388, 2401]); 
var width = doc.internal.pageSize.getWidth;
var height = doc.internal.pageSize.getHeight;
doc.addImage(img, 'JPEG', 0, 0, width, height);
doc.addPage();
doc.addImage(img1, 'JPEG', 0, 0, new_width, new_height); // another image 
doc.save("gg.pdf");

我如何为JSPDF上的每个新图像分配新的宽度和高度，为新jspdf（'px'，'px'，[388，2401]）;仅适用于第一个图像这样我就可以为添加到PDF的每个图像设置新的宽度和高度？任何建议将不胜感激。

原文

var doc = new jsPDF('px','px', [388, 2401]); 
var width = doc.internal.pageSize.getWidth;
var height = doc.internal.pageSize.getHeight;
doc.addImage(img, 'JPEG', 0, 0, width, height);
doc.addPage();
doc.addImage(img1, 'JPEG', 0, 0, new_width, new_height); // another image 
doc.save("gg.pdf");

How can I re assign new width and height for every new image on jspdf as new jsPDF('px','px', [388, 2401]); only works for first image any way to do so that I can set new width and height for every image I add to pdf? Any suggestions would be appreciated.

我们似乎同意，PX似乎被应用为每英寸54个

// We must declare 1st page canvas before use "p", is for portrait then default units , [size x, size y] 
var doc = new jsPDF("p", "px", [388, 2401]); 
var width = doc.internal.pageSize.getWidth;
var height = doc.internal.pageSize.getHeight;
doc.addImage(img, 'JPEG', 0, 0, width, height);

// oddly the order for new page is reversed, so size, then orientation
doc.addPage([new_width, new_height], "p");
doc.addImage(img1, 'JPEG', 0, 0, new_width, new_height); // another image
 
doc.save("gg.pdf");

，但是始终检查缩放这两个单元应该是相同的单元，它们报告的维度相同，差异的外观也许是一种幻想。相同的文件，面对页面，一个窗格集作为mangamode

However always check the scaling these 2 should be same units just rotated, they report same dimension and appearance of difference is perhaps an illusion. Same file, facing pages, one pane set as MangaMode
