Good information here to be sure. I elected to change the registry settings for my PP application. Problem is that I was trying to capture a single image off of an individual slide, not the entire slide.

For those considering using the Adobe Photoshop option to ‘upsample’ the resolution, there is a FREE (and easy) alternative. Suggest downloading the PAINT.NET (freeware) program for this.

According to Wikipedia, “Paint.NET is a raster graphics editing program for Microsoft Windows. It has evolved from a simple replacement for the Microsoft Paint program into a powerful editor with support for layers, blending, transparency, and plugins.”

In any event, thanks for the info…

@Ruwan I haven’t tried to extract images from Excel, I presume the saving as web pages and choosing highest res for the images would be the best option.

Hi David,

I came across your website while looking for ways to convert images derived in Excel to 300dpi TIFF or EPS files (for reasons similar to those of Chris).

Have you ever had to do this for the scientists that you work with? I’m afraid sometimes we don’t have a lot of foresight when we are preparing our figures!

Any advice would be greatly appreciated.

Ah, well done Chris on making it into PLoS. I just gave your paper a mention in my Geeky Bits micro blog on http://www.sciencebase.com

Hi David. Our paper was finally published on June 6th. You can find it here: http://dx.plos.org/10.1371/journal.ppat.1000082
The figures aren’t much to look at, but those are the ones they were giving us a hard time about. They ended up being fine. Thanks for your help!

See http://support.microsoft.com/kb/827745
on how to change the resolution of a PPT slide that you export as a picture. Max resolution permitted is 300 dpi. However, you can 600 dpi by exporting as enhanced meta file, which is (at least on my computer) at 600 dpi. Then you can convert EMF to other formats like TIFF in e.g. MS Office Pict. Manager. If you do use MS-OPM, don’t forget to resize the image by 100% before saving as TIFF.

You can also resize your page under File – Page Setup, and then simply do a Save as PNG.

I had a .wmf figure that I wanted to export at high-resolution. I increased the page dimensions to 30 in x 20 in and the resulting PNG was beautiful at 2880 x 2112. You could go even larger than that

So it is! I tend to work with RAW camera files, TIFF and JPEG, so haven’t really had a need to look into PNG, but it does look like a powerful format and infinitely better than Compuserve’s GIF…
