PowerPoint isn't an image format, it's a document format. Extract the images and use them.
For vector images I'd strongly recommend PNG.

I'm so sorry Chris misses the question so completely. I don't want to create a bitmap from my PowerPoint diagrams. That's what 'extract the image' is. What I want is a vector graphic in my article. I get the impression this is only possible in HTML5. I DONT want an href to a bitmap. That's what an image is. I want a vector graphic. Thanks for not helping.

Please leave the attitude at the door. I'm trying to help.
Can you please explain what you mean by "vector graphic". A PNG file is a graphics file that can contain images in vector format. I use this all the time. Your other option is to upload an SVG (Standard Vector Graphics) file - this is also supported.
An "href" is only used in an anchor tag. For an img tag you use the src attribute.
cheers

One attitude stems from having the assumption you know everything. I definitely don't have that attitude. My thanks to Chris for correcting my misuse of href. As for PowerPoint, yes, I said I would worry about converting it to an acceptable vector graphic format. Vector graphic? Why, if I google that term, I get plenty of ideas what that is. It involves lines, arcs, rectangles, and other geometric shapes. Not so much pixels, as in a bitmap. More along the lines of lines. Less along the lines of big chunky pixels. Since Chris says PNG can contain images in vector format, I'll proceed along the lines of me not knowing everything. But then, if I find 'images in vector format' (in my meaning) was just an excuse for not understanding, well, I've said enough on this.

How about we just leave you in peace to work out what's best for you.
If you do wish our help in publishing your article and your graphics then we're happy to help. Just send us whatever you have and we'll ensure it look good and works on the web.
We've done this a few times. I'm sure we could muddle our way through it.
cheers

I would not have asked my question in the first place if I was not looking for an answer. What did I get? Use PNG. It doesn't have vector graphics, but go ahead, use PNG. The spec says, "Conceptually, a PNG image is a rectangular pixel array ... Three types of pixel are supported:" etc. No vectors.
Just muddling your way through is what I was worried about. Since you've done this a few times, maybe I'll find a sample article with good diagram muddling. I can always hope.
cheers

Wow - do you really need to be so rude?
I use PNG daily and I can assure you that PNG can store information in vector format.
I have asked you a couple of times to either explain what you need so I can answer more specifically, or to send us what you have and we'll do whatever we need to do to get your article posted.
I don't understand where the attitude is coming from. We're trying to help. Tell me specifically what you are trying to do, what's blocking you, and I can help. I'm not muddling through, I'm not making stuff up, and I have been doing this for a long, long time. I can help if you want help.
cheers

Ah, so you use Fireworks as well. Wonderful product. And yes, I can also confirm that it stores vector information perfectly well.

Guilty as charged.
The truly sad part is that I much prefer FW3 to the latest versions. FW went the way of so many other products and just become more cluttered with features that got in the way.

FW4 was my favourite version - it came with direct XAML support.

Sure thing, Chris. Point us all to an example of your PNGs on the web. We'll view source and see what your circles, or rectangles, or polylines are made of.

Chris is talking about the fact that Macromedia Fireworks (long before Adobe ruined it) allowed you to store vector imagery inside PNGs. Fireworks was a vector editor that used PNGs as its native file format - and these would render straight to the web. Honestly, you are coming across as a petulant child here, trying to show up teacher. Perhaps, if you hung the attitude up for a bit, you would have seen that Chris was trying to help you. Now you're just coming across as a troll.

I think the point was not about what a vector image is or not. I think the point was about "powerpoint" as vector image editor.

Strangely, all further replies to this message seem to be blocked. I said:

Hi,
I published an article, and posted also its relative code. Someone said that this code was not readable. I downloaded the .zip file, corrected the wrong files, removed the old file from article, and uploaded the new one.
He says that this file still not readable. It could be because the uploaded files are to be moderated? I saw that in revision page the last revision is published two hours after my publication. But the post where Michael_Davies says is unreadable is wrote after four hours.
You can see that at this discussion.
I see the time wasn’t in my time-zone. Wich one is used? I’d like to know if he download after or before the pulication...
Thank you

I can see that the only two files in there are dated today, which means they were uploaded today. Are the files you uploaded today the correct files?
Thanks,

Yes, I changed only two files. The problem was about a not perfect compatibility between VS2012 and VS2010. The first one runs the Team Foundation engine only if marked in .sln file. The second one crashed because in .sln file wasn't marked but there was a reference in .vbproj file.
I opened the solution with VS2010 and saved again. Now all works perfectly. Thank you

You might want to give this tool[^] a try. It completely removes the source control bindings from a project, in case you've missed anything.
I've posted a link in the discussion on your article as well.
