How to Embed Font in Existing PDF Documents inside Android Applications
This technical tip shows how to embed a font in a PDF file inside android applications. PDF readers support a core of 14 fonts so that documents can be displayed the same way regardless of the platform the document is displayed on. When a PDF contains a font that is outside the core fonts, embed the font to avoid font substitution. Aspose.Pdf for Android supports font embedding in existing PDF documents. You can embed a complete font or a subset. A font subset embeds only the characters that are used and is useful where fonts are used for short sentences or slogans, for example where a corporate font is used for a logo, but not for the body text. Using a subset reduces the file size of the output PDF. However if a custom font is used for the body text, embed it in its entirety.
//your code here...The following code snippet shows how to embed a font in a PDF file.
//Open the document
com.aspose.pdf.Document doc = new com.aspose.pdf.Document("/mnt/sdcard/input.pdf");
//Iterate through all the pages
for(com.aspose.pdf.Page page : (Iterable<com.aspose.pdf.Page>)doc.getPages())
{
if (page.getResources().getFonts() != null)
{
for(com.aspose.pdf.Font pageFont : (Iterable<com.aspose.pdf.Font>)page.getResources().getFonts())
{
//Check if font is already embedded
if (!pageFont.isEmbedded())
pageFont.isEmbedded(true);
}
}
//Check for the Form objects
for(com.aspose.pdf.XForm form : (Iterable<com.aspose.pdf.XForm>)page.getResources().getForms())
{
if (form.getResources().getFonts() != null)
{
for(com.aspose.pdf.Font formFont : (Iterable<com.aspose.pdf.Font>)form.getResources().getFonts())
{
//Check if the font is embedded
if (!formFont.isEmbedded())
formFont.isEmbedded(true);
}
}
}
}
//Save the document
doc.save("/mnt/sdcard/FontEmbedded_output.pdf");
