Question : Will saving an image drafted in PowerPoint as a TIFF file reduce any part of the clarity of the image?

I am responsible for submitting some images for publication in print and online.  The image was given to me already within a word document (see attached word document with the embedded image of chromosome).  I believe the image was made in powerpoint and copied into word.  In any event, the publication company is asking that the images be submitted as TIFFs, I think probably because most of time the people are submitting are high-resolution images taken from microscopes and other scientific equipment.  Basically, I need to know if I should right-click on this embedded image, save it as a TIFF, or if I can just upload it as is.  Although they ask for TIFF images, they do allow for submission of .ppt, .eps, .xls, .psd, .jpg, .gif, .ps, .pdf, .doc, .tex files.  What is the best format to submit these basically clip-art-made images?

Answer : Will saving an image drafted in PowerPoint as a TIFF file reduce any part of the clarity of the image?

It's not already a picture (a raster image), so whether it compresses again (lossy compression, like a JPG has) or not (lossless compression, like TIF or PNG) doesn't matter.

I think this will work in Word, but I'm not sure. Choose File | Save As and select Webpage (HTML) from the "save as type" dropdown. You should get the File.HTML and a folder of supporting files. The image file would be in there.

Ah, nevermind. Just tested. Save as HTML does work. You have a PNG and JPG there. But it doesn't matter all that much because in Word 2010 (which is what I'm using here), I do have "save as picture" as an option on right-click, so I just saved it as a TIF from there. It's attached.

Too bad you can't get at the original drawings. Those are vector-based, and that would actually be best for print.
