May 24, 2016 I am using the latest version of jsPDF 1.2.61, While adding an image it adds an blur image even though the image is of high quality, if I the same base64 in on-line decoder it produces the perfect image as the original, but the base64 produces low quality when I use addImage functionality of jsPDF. Snippet:.
Apr 14, 2013 I even tried updating the example on the jspdf.com website, and I get the same error. Is there something I am doing wrong here? These are images generated from Gimp with the .jpg extension. Thanks!
Mar 10, 2016 addHTML squishes width of image in page #652. Closed scaleFactor = 1 was causing our multi-page or "split page" PDF generated by jsPDF to appear skewed. Our final, modified code looked like this: var pdf = new jsPDF('p', 'pt', 'letter'); pdf.internal. @joshuapowell how you calculate the scale factor?
Aug 22, 2014 If you do have that option enabled, it will create a canvas at whatever scale will match the pdf size, then draw the scaled image to that canvas. Then it'll pass data through to the pdf.addImage() method. Creating the additional canvas at a scaled size with a scaled image dramatically reduced the image
Feb 26, 2015 I am using pdf.addImage(imgData, 'PNG', trackPositionOnPage.x, trackPositionOnPage.y);. to add an image to my pdf. This is working perfectly fine. However, now I want to center it on the page in pdf, and for that I want to get the size of image in pdf, just like I got the size of a text string using
toDataURL("image/jpeg"); var doc = new jsPDF(); // using defaults: orientation="portrait", unit="mm", size="A4" var width = doc.internal.pageSize.width . While this doesn't include provisions for printing multiple pages it does scale the image to page width and reframes the height in ratio to the adjusted width:
Dec 27, 2014 toDataURL('image/png'); /* Here are the numbers (paper width and height) that I found to work. It still creates a little overlap part between the pages, but good enough for me. if you can find an official number from jsPDF, use them. */ var imgWidth = 210; var pageHeight = 295; var imgHeight = canvas.height
toDataURL("image/jpeg"); var doc = new jsPDF(); // using defaults: orientation="portrait", unit="mm", size="A4" var width = doc.internal.pageSize.width . While this doesn't include provisions for printing multiple pages it does scale the image to page width and reframes the height in ratio to the adjusted width:
Dec 18, 2015 A small update to this - I managed to get the page size to fit and to eliminate the black border by adjusting the width of the HTML element (DOH!@) but the text is stretched and broken - I guess because my jsPDF units (mm) dont exactly match my pixel width - I was not able to find the sweet spot between
Apr 11, 2015 Actually, just tried with a larger image/element and even in portrait made the image cut off instead of resizing it to fit in the page. Any ideas? Is the best solution resize the image myself to the size of a page before passing it to jsPDF?
