John, I agree that there does not seem to be any problems with the
images for the census records. And, as you say, they ARE relatively
files. It's when the Lizard Tech technology is used for the maps
rub comes in. The maps are relatively much larger than the small
I've NEVER had any problems with the census graphics loading, or in
maneuvering around on the page. But, the technology doesn't seem
the same with the very, very large maps.
I think we're talking about two different things here. Just so
wanting to download and save MrSID graphics, let me try to explain.
I don't know which MrSID viewer you downloaded, but I got the one
recommended on the web site. When I pull up a .SID file in it, then
to "export" it (the only option, there is no SAVE or SAVE AS), and
choose the drive/directory to save it, the ONLY option available is
(In the "Save as Type" box, clicking the down triangle shows only
I would LOVE to find out which viewer YOU are using, and how you
get the option to save as a .JPG file.
Yes, when saving the file from the web site, one may choose, .SID,
or .BMP. But, if you read the instructions, you see that you can
ONLY the portion of map being viewed (in .JPG format) if you are in
BROWSER mode. If you go to DETAIL mode, which is the only way you
can download the ENTIRE full-sized map, you are told that you can
download as a .SID file to get the entire map in original size.
In the MrSID viewer, even on the icon bar, the only thing to click to
is a button that says "TIF". If you are using a different viewer
which is MrSID Viewer, version 184.108.40.206 and comes directly from
Tech, I would love to find out where to get it. If you ARE using the
one as I am, I would love to find out how you are able to export the
picture as a .JPG file. Something is wrong here.
The problem I'm having here is that the standard graphics format has
and still is, to either have a choice of downloading as a .JPG or
both of which result in a REASONABLY sized file. Now, a company,
Lizard Tech, comes up with an entirely different format, one which is
NOT accessible by ANY other graphics program, including Paint Shop
Pro, Photo Shop, Photo Works, Adobe Photo, etc. This means down-
loading and installing yet another 3rd program to be able to view and
print a picture. And, MrSID viewer gives NO ability to "tweak" a
scanned graphic. Therefore, one must convert a .SID file to
else that WILL be accessible in a NORMAL graphics program, and then
work with it. And I can tell you that I find very, very few graphics
line that are have as good a resolution, contrast, etc., as they CAN
with a little tweaking.
The only option I have ever seen for downloading as a .JPG is from
BROWSER mode of the maps utility at Ancestry, and you are told
that you can download ONLY the portion being viewed. That means if
you are viewing the map (BROWSER mode), and can see it all, THAT'S
the exact graphic file you will download -- so small you can't read
thing on it.
I've read some of the other replies and it seems that MrSID causes
kinds of problems, some with various MS OS's, and some with MAC.
You see, that's the point. Why bring in yet another untested,
sometimes unworkable utility for the same of doing something new?
When I download a graphics file, I expect to be able to view it, to
it, to tweak it (if needed), and to print it, without having to use a
party program and without having to make time consuming conversions
to a format that IS compatible with all OS's.
John, you, and a couple others, have missed the entire point. For
minimal use you do with the census images, it works fine. But it
NOT work satisfactorily for larger images such as the maps. Let me
tell you EXACTLY the story of one I just downloaded as a test. It
was "Across Kentucky, 1862". The .SID format is 3.5 Mb (that's
MEGABYTES!); converting it to a .TIF file in the MrSID Viewer
(the only option is .TIF), resulted in a file that was over 101 Mb
(that's ONE HUNDRED AND ONE MEGABYTES!), and took
almost 2 minutes on my "power machine". Does that sound like it
is satisfactory to you? Then, I can access the .TIF file in Paint
Pro and convert the .TIF file to a .JPG. (Forgot to mention that
converting to .TIF, two other files are created, a .TFW and a .TAB,
which are small but still take up space.) Anyway after two
I finally get a .JPG file that is about 1.5 Mb. And, when working
a 101 Mb .SID file, my "power system" just doesn't have enough
memory or resources to do anything else.
You know, some time ago another company "experimented" with the
.PNG format, and a lot of web sites started using THAT format for
their graphics files. It was a bust! How many times do you see that
format available on the web today? NOT! MrSID will go the same
In short, why be so enamored with MrSID for census graphics. You
could see a .JPG and use the scroll bars to look it over, just as
as scanning with MrSID. Plus, when you downloaded you would
get the ENTIRE image in .JPG or .BMP format and have to do not
conversions to make it standard, and have to use no 3rd party program
to view it. KISS!!!!!
For your information, Ancestry can keep the MrSID format for
census graphics as far as I am concerned. I've no problem with that.
But, the map retrieval utility sucks!
