 1 | # HTMLWithImagesToPDF
 2 | 
 3 | ## Description
 4 | 
 5 | This app showcases the following:
 6 | 
 7 | 1. Loading an HTML file into a web view (actually both a `WKWebView` and `UIWebView`),
 8 | 2. Generating a PDF using either
 9 |    1. the web views' `viewPrintFormatter()` or
10 |    2. a `UIMarkupTextPrintFormatter`,
11 | 3. Printing a PDF using either
12 |    1. one of the web views' `viewPrintFormatter()` or
13 |    2. a `UIMarkupTextPrintFormatter`
14 | 
15 | 
16 | ## Bug
17 | 
18 | Generating a PDF using a `UIMarkupTextPrintFormatter` will not render the images of the HTML file. Unless the HTML code has been loaded into a web view beforehand.
19 | 
20 | 1. Run the application.
21 | 2. Tap `Create PDF` and then `UIMarkupTextPrintFormatter`: a PDF is generated from the `index.html` file and loaded into both a `WKWebView` and a `UIWebView`. Images are not rendered.
22 | 3. Tap `Load HTML` and then `index-img.html`: the HTML code is loaded into both web views and the images are displayed. The HTML code is not the same as the one we used to generate our PDF (**but the `img` tags are the same**).
23 | 7. Re-do step 1: tap `Create PDF` and then `UIMarkupTextPrintFormatter`: another PDF is generated and loaded into the web views. And this time **with** images.
24 | 
25 | This behavior tells me that `UIMarkupTextPrintFormatter` does support `img` tags. Also confirmed by the fact that `Print PDF` > `UIMarkupTextPrintFormatter` shows a PDF with images (actually only one image is displayed).
26 | 
27 | ## Note
28 | 
29 | The `Create PDF` > `WebView.viewPrintFormatter()` action creates a PDF from what each web view is **currently** displaying, that can either be nothing, one of the HTML loaded beforehand or a PDF loaded from a previous execution.
30 | 
31 | The `Create PDF` > `UIMarkupTextPrintFormatter` action always creates the PDF from the `index.html` file.
