[jira] [Commented] (PDFBOX-1571) Images Look Fuzzy

["Maruan Sahyoun (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-1571?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13660406#comment-13660406 ] 

Maruan Sahyoun commented on PDFBOX-1571:
----------------------------------------

Hi,

looking at the document in Adobe Reader and extracting the 'Hello' image using PDFBox and Adobe Acrobat there is no difference. The image is already fuzzy in the PDF so there is no better quality to be expected after extraction. 

Could you verify this?

> I tried to create a image and superimpose on the PDF, the image looks fuzzy. Also if i try to zoom the image created it looks fuzzy even for the first Zoom Out. 
> I tried increasing the resolution this is increasing the image size while superimposing and even looks more fuzzy with a huge image. Tried with the below piece of code.
