Filed Stackoverflow here: https://stackoverflow.com/questions/67753141/jspdf-html-method-doesnt-recognize-the-image-quality-option
Basically something is up with the jsPDF.html() method in which any img element blows up the file size. For me I have a 50kb image that blows up the PDF to 3.3mb with nothing else in it.
So I have to selectively replace those image elements with onclone.
My workaround:
pdf.html(ele, {
x: 10,
y: 10,
image: {
format: "JPEG",
quality: 10, // doesn't affect it
compression: "FAST" // Doesn't do anything
},
html2canvas: {
onclone: (doc) => {
// doc returns the entire document, not just ele
let target = doc.querySelector("#theElement");
let images = target.querySelectorAll("img");
let targetRect = target.getBoundingClientRect();
images.forEach((img) => {
let rect = img.getBoundingClientRect();
pdf.addImage(img, "JPEG", targetRect.x - rect.x, targetRect.y - rect.y, rect.width, rect.height);
img.remove();
});
}
}
});
