从文本中获取字体和字体大小？

Question

I want to make an application for auto finding font.

Therefore, I try to get a font and font size from PDF text with Acrobat SDK.

I examined samples and documents, but I could not find it.

 CAcroPDDoc pdDoc = new AcroPDDocClass();
 pdDoc.Open(filename);
 Object jsObj = pdDoc.GetJSObject();
 Type T = jsObj.GetType();

 // no idea for getting font and font size...

My tools : Visual Studio, C#, Acrobat DC, Acrobat DC SDK

• For example PDF text, font and font size on Acrobat DC

Best regards

Answer 1

Acrobat JavaScript and, therefore, the JSO doesn't have access to the properties of text in the page content. The best you're going to be able to do is infer the size from the bounding box height but that won't be accurate since the bbox includes the leading. You can't get the font name at all.

You can get that information if you create a plugin but that would require C++ which you don't have listed as an option in your question.
