Saving Powerpoint illustrations as high quality image files

[JimClark49]

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:

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

Thanks

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.

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.

Can you upload the file here?

I am sure I could, but as it is an original, and as yet, unpublished image I do not want anyone to copy it.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.

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.

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

Ok tried Gimp, but images are still poor quality (pixellated somewhat when zoomed in).
What specific values should put in for the following:
width
height
resolution

PS: when I try to increase the values and click open, the computer crashes!
