Export to jpeg

Hello, 

I am new to Corel. I started learning it recently. Great experience so far but getting n number of illy doubts. 

for now, I have 2 doubts- 

1. when I am exporting a file to jpeg, it's leaving extra space on the right and topside. 

2. When I am importing a PDF file, I am not able to use the content directly. It seems everything in PDF is in curve form. How to use the content? 

Regards,
