I'd like to post some images - mainly weather graphs - from web pages, but I see that it's not possible to post HTML files.

So, I'm wondering how to post these sorts of images. I can save them as Web archive, single file (*.mht)", Webpage, complete (*htm; *.html), Webpage, HTML only (*.htm; *.html) or a text file.

I'm also having trouble posting data in 'table format'. Tabs and spaces don't separate the data evenly in columns, it seems.

Any advice would be appreciated! Maybe I need to use BBCode, but I have no idea how.

If the weather page generates an image which can be saved, that should work. Do you have an example of a site I can do some testing with?

I need to add the BBcode for tables. It doesn't look difficult, I just need to find the time to get it done. I'll keep you posted on that.

Hi David,

Here's the site I'm interested in:
http://www.ndbc.noaa.gov/station_page.php?station=45002

If you scroll down and click on any of the "triangle" icons you get a 5-day plot of that parameter (wave height, air pressure, wind speed, etc.).

Unfortunately, these graphs are overwritten every day, so a simple link to the website won't work to access data for a past date. I'd like to be able to save ('freeze') a graph and post it.

No hurry at all. I just thought I might be missing some easy way of doing this.

The Graphs are PNG images. I have downloaded (Saved as) Png files. Opened them in a photo editor program and saved them as JPG. becasue the same JPG file is 1/4th the size of a comparable PNG file. Then I upload to my fav. file sharing site that allows linking and voila.

Another way that may not be as refined is to line up your graph on your monitor as you'd like to see it and hit the print screen key. Then hit paste in your fav. graphics editor and you have an image of the screen.

So you guys know this secret language and I don't have a decoder ring. I will have to just sit back and enjoy the fruits of your labors as I am unable to play in your world. Do you guys know how to play video game too?

Interesting that you ask....I used to spend a lot of time playing with the Microsoft Flight Simulator and creating model aircraft add-ons and such for upload as freeware. In order to do this video "game" well, it has taught me a few things about computers.

Oops sorry, Microsoft Flght simulator 2004 Version.
The aircraft is a Spartan Executive 7W (c.1934) That I had created a few years ago. Before our C22 days.

Here's one of those graphs for instance in jpg format

Nice images, Bilbo.

I don't know my PNGs from my PONGS, but I could probably follow your method.

So, what photo editing program did you use to convert to a JPG file?

P.S. I like the dog wink/wave - very cool

You can use windows Paint to convert those png graphs to jpg.
I use an old copy of Corel Photopaint.
Most people would use Adobe Photoshop to edit images.
I also use a web place that allows me to link to my uploaded files
Some don't but http://photobucket.com/ does.
copy and Pasting is real easy from photobucket because it automatically prepares the img code and copies with one mouse click.
Even moving gifs and movies are allowed:

Bilbo,
That horse gif is cool, but frankly a bit freaky



David

Second that! (freaky horse)
So what happened to the rest of the horse, Bilbo? Dog food?

Just wanted to report success using Bilbo's method and Microsoft Paint. I just opened the PNG images in Paint and saved them as JPGs. Then uploaded them to my photo hosting website and grabbed the links.

Here are the results: viewtopic.php?f=12&t=220&p=1431#p1431

Thanks for the help, guys!

I think that it's really a quarter horse instead of a full one.


YEA!!1 it worked. It was neat to see the graphs on top of each other relative to wave height, wind speed and such.


No problem. It was easy.

Bilbo,

ok, I'm slow on the jokes - quarter horse makes sense

One more question: The graph lines 'bled' a little. Do you think a different file format would work better, like GIFF? Or maybe I'm losing resolution in Paint?

They are quite legible though, and I'm pleased with them. I'm just getting picky now.

Regarding weather graphs: there is one other weather graph that is always interesting when pressure drops - it's the 'triple graph' of air pressure, wind speed and gusts:



Wind speed & gusts are almost a 'mirror image' of the air pressure curve. It would be nice to have wave height superimposed too.

BTW: On this one I skipped over Microsoft Paint altogether. I noticed that if I right-click on the web site graph and choose "Save picture" I get a bitmap file (*.bmp) that I can upload directly to my photo upload site.

What may be happening is that the resolution (DPI) Dots per inch may be changing. The dots are actually the small squares that have individual colors in each one. If this density od DPI becomes smaller when saved, the quality is lowered as the file size is also smaller.

Or the size of the graph image is changing so that the thin lines are losing some definition. If the image becomes smaller in size and the DPI number remains the same, then the quality is lowered. This can be more noticeable with the fine lines that may be only one pixel (Color Square) wide. Any thinner and they disappear. Another issue with fine lines is something called "dithering" This is a blurring of the image where a solid definiton between different colors used to be.


Yes, That would be interesting to see. I'd assume that there are a few other factors that enter into thew wave height issue. Wind speed and the duration of a constant speed. Gusts may change things but not the same as a constant wind. Water depth will have somewhat of an influence. Reflected waves that aren't going with the wind direction can do something to the peaks. The too waves can travel into bays and around objects. Distance from shore as well as the terrain elevation contours can change the wind. One thing that I'm noticing on our lake is that the wind can change speed AND direction closer to shore. It can be deflected or funneled in the area close to the tree line. OF course a mountain lake will have more diverse wind directions as you travel between the creek bed valleys and the more steep hills around the lake.



I guess that works as well

The neat thing about Buoy 45002 is that it is relatively immune to topographical effects, both above and below the water. It's in 181 ft. of water in the middle of northern Lake Michigan, and the closest land to the ODAS buoy is over 15 miles away on the Door County peninsula of Wisconsin. So, if - as you say - the wind is steady over many hours, the buoy data reflect the interrelationships between wind speed, wave height and air pressure rather 'cleanly'.

Nearshore, however, there are plenty of topographical effects on the Great Lakes. The one I'm most familiar with is funneling on the Straits of Mackinac. Some days it gets real challenging

But that makes it all the more fun
