یک سند PDF ساده از طریق Swift API ایجاد کنید

import SwiftyHaru

let pdf = PDFDocument()
let page = pdf.addPage()
let font = pdf.addFont("Helvetica-Bold")
let text = "Hello, World!"
let fontSize: Float = 24

page.beginText()
page.setFontAndSize(font, fontSize)
page.textOut(100, 100, text)
page.endText()

pdf.write(toFile: "/path/to/document.pdf")

سند PDF با تصویر جاسازی شده از طریق Swift API

import SwiftyHaru
let pdf = PDFDocument()
let image = UIImage(named: "yourImageName")
// Create New PDF Page
let page = pdf.addPage()

// Get the size of the image:
let imageSize = image.size

// Calculate the width and height of the image in points:

let widthInPoints = (imageSize.width / image.scale) * 72.0
let heightInPoints = (imageSize.height / image.scale) * 72.0

// Add the image to the PDF page:

let x = 0.0 // X coordinate of the top-left corner of the image
let y = 0.0 // Y coordinate of the top-left corner of the image
let imageRect = CGRect(x: x, y: y, width: widthInPoints, height: heightInPoints)
page.addImage(image, rect: imageRect)

//Save PDF

let data = pdf.generatePDFdata()
// You can then save the data to a file or display it in a PDF viewer

چگونه از طریق Swift API، حاشیه نویسی متن را به سند PDF اضافه کنیم؟

import SwiftyHaru

// Load an existing PDF document
let pdf = PDFDocument(fileAtPath: "example.pdf")!

// Get the first page of the PDF document
let page = pdf.getPage(1)

// Create a text annotation with a yellow background color
let annotation = PDFAnnotation(text: "Example Annotation", rect: CGRect(x: 100, y: 100, width: 200, height: 50))
annotation.color = .yellow

// Add the annotation to the PDF page
page.addAnnotation(annotation)

// Save the modified PDF document
pdf.write(toFile: "example-with-annotation.pdf")
