Hi all,

Tried the following advice from Microsoft on converting an illustration I created in powerpoint into a high quality jpeg, but it hasnt made a blind bit of difference:
http://support.microsoft.com/kb/827745

Could anybody please advise me on what I can do to get a high quality Jpeg of a PPT?

Thanks

When you say "an illustration" - is it something that you've drawn yourself, or does it use imported images ?

You can't make a better quality image or off one that was poor in the first place. ..

Download htmlhelp.exe, its free and is a really easy tool to take screenshots and save as jpegs, gifs, or pngs. You can quickly and easily crop just the part of the image you want.

He wants high quality apparently, which I'm taking as high resolution.

Its a medical illustration I created myself and will be included in an article I publish.
The illustration was easier to prepare in powerpoint as I could construct text boxes to explain things.

It must be high quality, so any suggested programs should ensure that the image retains the high quality with which it has been originally designed.

It helps if you start with a large page size in Powerpoint.

Assuming that this is vector art in Powerpoint (lines and boxes) and not pasted photographs or bitmapped clip-art (and that you also have access to Adobe Photoshop):

In Powerpoint, create a new blank presentation, add an empty slide and copy your diagram onto that page. Remove the title slide and save as PDF

You can open that pdf file in Photoshop at any resolution

But opening it in Photoshop rasterises it. You cannot get extra resolution quality when the original is low res. That's assuming the OP has Photoshop which I feel is unlikely. If he had Photoshop it's a chance he also has Illustrator and if so, there would be no questions about Powerpoint diagrams, etc.

I've used snagit for exactly the exactly the same purpose the publication editors have never had any problems with using the images for web or print.

Get a free pdf printer.

Then print it as a pdf.

Thanks for the further replies.

I have no specialist software and am not a professional artist. The illustration is merely to supplement my written work and conceptualise the ideas I am talking about. The illustration does contain an imported image of the heart (used from an open licence databank I have of medical images).

Snag it seems rather similar to the snip it tool does it not?

I cannot understand why the registry edit chaging dpi to 300 did not work. Especially as I followed all instructions given by Microsoft.

I am sure I could, but as it is an original, and as yet, unpublished image I do not want anyone to copy it. I am sure nobody will, but I do not want to take that risk.

OK, give us more clues:

Why do you want a JPEG?

What are you going to do with it / how are you going to publish it ? Online only ? Conference poster ? Paper for submission to a journal ? Thesis ?

Can you get a suitable heart image as vector art ? If not, can you share that bitmap image and maybe one of us with Illustrator could convert it to vector art ?

The reason is that I have had an invited review article accepted by a medical journal. They are requesting the illustration (or Figure) be in JPEG format when I submit the final revised version.

I wouldn't just be able to attach a picture of the heart, it would have to be all the text/arrows that surround it. Those text/arrows have been done in Powerpoint and appear around the image of the heart (and of a seperate smaller image of a blood vessel).


The publishing will be in print and online format as is standard for most medical journals.

Can you tell us exactly what the problem is with the JPEG image file that you get ?

Also - what format is the picture of the heart ? (JPEG, GIF, PNG, BMP, something else?)

If you can get a vector image heart into the diagram to replace your bitmap then you can follow the
- save from powerpoint as pdf
- open in photoshop/gimp/your-image-tool-of-choice at a very high raster resolution
- voilà, publication-ready high-def jpeg image
route

Unless the bitmap is already a huge 1200dpi publication-ready image file ?

Saved as PDF and is very high resolution! Powerpoint to Jpeg was poor resolution.
Thus, I will convert PDF to JPEG, but can you recommend a free program that I can do this with?

Download GIMP and File -> Open

In the advanced Open options you can specify a suitably high dpi rate

Then save out as a JPEG with the least possible compression
