Converting HTML to PDF using e-mail source html

Aspose.HTML Product Family

I am trying to convert the e-mail html content to pdf.
Currently i am using wkhtmltopdf, it converts in a specified “200” dpi resolution.
Now i am trying to convert it aspose.html and convert etc. and the resolution is to big, it looks like.

var htmlf = new Aspose.Html.HTMLDocument(cHtmlFile);
Aspose.Html.Saving.PdfSaveOptions pdf = new Aspose.Html.Saving.PdfSaveOptions();
pdf.PageSetup.AnyPage = new Page(new Aspose.Html.Drawing.Size(1550 , 2193), new Margin(70, 60, 70, 60));
pdf.HorizontalResolution = 300;
pdf.VerticalResolution = 300;
pdf.JpegQuality = 80;
Converter.ConvertHTML(htmlf, pdf, cPdfFile);

When i use a drawing size of 793 x 1122 the resulting pdf size is 21,0cm x 29,7cm (A4 size).

When i use a drawing size of 1550 x 2193 the resulting pdf size is 41,0 cm x 58 cm.
This size is like outlook/wkhtmltopdf.

I am trying to convert it so the destination is “readable” using pdf.
attached “2024-04-15_20-56-14.jpg (45.6 KB)” is printed from outlook.

Horizontal Resolution only affects the resolution of images inside a PDF document, text and other elements that are not pictures are not affected. Please clarify, what do you mean by readable text? Because the text in the resulting PDF document is not a bitmap image and when viewing the PDF, it is scaled by the viewer to the current scale of the viewer without quality loss.

Resolution in pixels is no problem at all (of course) in this example PDF.
But i have PDF’s with images in it. I want to create the PDF with images embedded in a 200 or 300dpi resulting PDF with images.

How can i create a PDF with 21 x 29,7cm with images in 300 dpi ?
