I have a map I vectorized with wintopo pro.It is a lake map.I want to
delete every line not within the lake.I made a shoreline tif to try and
overlay on top to see what to delete.But I guess you can't load two tif
at once.Any suggestions.
Thanks
Jack

Now, every time I open my pc, my AVG anti-virus shows this  warning:

"Multi thread detection
C:\Program Files\SoftSoft\Win Topo\win Topo.exe\Runtime packed yoda"

I was unable to "Remove selected infections", so I did uninstall the
program, but it still appears on "All programs".
Any help would be welcome.

This appears to be a recent error in AVG.

For some reason AVG has started complaining about software which is
protected (from piracy) with the yoda encryption system. This type of
encryption is entirely normal for commercial software packages.

WinTopo Pro is protected with the yoda encryption system. It is
nothing to be concerned about. It is not an 'infection'.

You should always ensure you download WinTopo from the www.wintopo.com
website or this Yahoo Group repository.

You might also try using a more reliable anti-virus solution.

Thank you very much for your quick help.

I am looking for a way to have text recognized and converted to text when
exporting to a DXF file instead of converting to a polyline.

Although text recognition (or "OCR") has been suggested occasionally by users,
there has never been sufficient demand to warrant the development required to
achieve that functionality in WinTopo.

We shall add this extra vote for OCR.

From: The WinTopo Support Team

Perhaps we do put it to a vote I'm thinking the majority of users just live with
it and didn't know we might be able too influance you in that direction.

I did decided on this software over the others due to the fine graphics
conversion ~ though it sure would be nice to have me text too as I am converting
hundreds and hundreds of hand drawn parts to CAD. Most having clean lined text.

P.S.
I am happy with the software

I haven't been using this forum too much. The hard drive with the loaded
software took a dump more than a year ago, and have not been too fast at
transferring the software or reduced information off of it.

But, am having occasional problems now.

Working on some scanned drawings in TIF format, that are in range of 800K file
size to 4000K file size. I am using version 1.66 of WinTopo. Before hitting the
O-T button, I take a check via information to see if I had better walk away or
not. The computer I am working on is a 500 Mhz, with 256 RAM, and it indicates
OK, (need 209 meg. or something, so) go ahead.

It takes a while, but creates a DXF file. Well, most of one on occasion. No
matter the size of file, big or small, on occasion I will get an error message
near end of processing that the Memory of computer is out of range. Cannot save.
Only thing I can figure out to get around such an error message is to do one or
two reductions in the morning, when cool, and first off too. Then it processes
the same failed file as yesterday and completes it. But then too one seldom
occasion I get the same error message.

Do I need more RAM, is computer too old, or what?



Wm.

On occasion, if I only have one drawing needing to be processed by WinTopo, it
will be taken to a very local blueprint shop. They go through female help very
fast it seems. Never writing down my instructions.

But the resulting image they hand me is often to 400 to 600 DPI. WAY more fine
than I need to work with. Is there a way to tell WinTopo to reduce the DPI count
to like 200 to 250 DPI and not have to get scanned again?



Wm.

OK, I am completely lost.  I am dealing with maps.  Raster maps that are
"Georeferenced" using UTM or Lat/Lon and a specific DATUM.  How does that
translate to the vector X,Y coordinates used by WinTOPO?  I like the results of
the raster to vector conversion a lot better than many other programs I have
tried but this But I don't see anything GEOGRAPHIC about the georeferencing
function at all.

For the size of image you are processing you would benefit hugely from more RAM.
Most of your 256Mb will be consumed just by WindowsXP before WinTopo even gets a
look-in.
If your system runs low on RAM while WinTopo is processing then WinTopo uses the
hard-drive swap-space as extra RAM in order to try to complete the process.
However, hard-drive swap-space access is about 1000 times slower than RAM, and
so the processing can take a long time when that happens.
Fortunately, RAM is very cheap these days and you can buy a Gb for just a few
dollars. Upgrade your RAM - it should make a lot of difference to the speed of
your machine when processing large images.

Yes, there is the "Image->Reduce Resolution..." option. But that is only
available in the WinTopo Pro version.

If you're not using the Pro version then you may be able to achieve a similar
resizing with a free imaging application like IrfanView.

The older hard drive and the older computer used to have about 390 to 400 in
RAM. Even though the CPU was slower, that RAM seemed to make a world if
difference. No matter what the size of drawing, it went...

Was then done altering in a few seconds.

WinTopo does not care what coordinate system you are using, it is irrelevant to
the conversion process. WinTopo is not involved with mapping projections.

The Georeference function is provided to allow you to specify the coordinate
'mapping' to be used to get from the raster coordinates to the vector
coordinates. What coordinate system you happen to be using is for you to specify
in the system into which you load the WinTopo output.

If your raster map is pre-georeferenced to lat/lon then you can consider the X
coordinate to to be the longitude and the Y coordinate to be the latitude.

WinTopo Pro 3.4

1. New image Resize facility. The image can be resized to any pixel width and height. This can be useful to decrease the size of an image which has been scanned at an unnecessarily high a resolution. Alternatively, for an image which is at too low a resolution, vectorisation can sometimes be improved by increasing its size.

2. The preview images on the various image options windows are larger.

3. Fixed the problem on the Image Information window when sometimes the Memory Required to Load was reported incorrectly.

4. New commandline option -paste to use the image from the clipboard (an image put on the clipboard by using the Copy option of another application).

5. New commandline option -rot to utilise the image rotation facility.

6. This version does not suffer from false warnings about Yoda from anti-virus systems.

WinTopo Freeware 1.71

1. Includes the same new image Resize facility as is in the WinTopo Pro version.

2. Fixed the problem with the One-Touch Vectorisation Settings window when choosing the Canny Edge Detection option. Sometimes the preview would be very slow and eventually incorrectly show a complete covering of green vectors.

3. Fixed the problem on the Image Information window when sometimes the Memory Required to Load was reported incorrectly.

Well, I downloaded the latest version of the Free Version of WinTopo to see just
how well it will convert a raster image to a vector.  I keep getting just a
single line and not the outline.  Any suggestions would help.

To get the outlines in WinTopo Freeware you need to choose the "Canny" option
for Edge Detection on the "One-Touch Vectorise Options" window.

Your mileage will vary with the 'Canny' edge detector. It is intended for
photographic type images where the position of the 'edges' can be somewhat
subjective. Take a look at the manual page to get a description of the canny
parameters which can be varied to get best results for a particular image.

If you've got images with clear edges then you'd be better off using the
'Simple' edge detector which is only in WinTopo Pro.

I take my converted Images of plans then use the DXF file to create an autocad
file and plan. Do this in one batch maybe once per year. Am using version 1.7,
1.66 and 1.45 at present time.

But something I do not remember is that the new DXF file is to some random, but
huge file dimensions. It is like X 10,000 larger than what was put in. If one
Autocad unit was one foot, I would be looking at a 3-40,000 foot long plot.
There are decimal places, but way far down there now.

As these drawings I get scanned into a TIF format, are not really big, I still
want them to result in a plan of equal size afterwards. I have played with the
buttons of WinTopo enough now, and still get the extra-extra large file sizes.

A drawing of 30 inhes long will result in a size same as that of an image object
of 50 inches long, almost exactly. Ratios are not same in either case, but are
still too huge overall.


How do I get to ratio of 1 = 1 ?


Wm.

I am finding out what Mike mentioned. I hear so often that the scanning process
does not alter things. But they are not same N-S or E-W when finished. Go to
take each scanning as a one off.

Not too much consistancy in the SET SCALING box at this time.

Wm.

I seem to be getting an error message of "Failed to Open Document" quite often
now on a couple of the images out of 1/2 dozen recently done. Then within a
second or two it is gone, and the whole computer is rebooting.

According to Windows Explorer the file is about 78 meg. large, and have 256 on
the system right now. I have done larger ones from same disk already but sure
getting troubles with this one.

Exact same file does not come up in a snap but looks OK in Adobe Photo Shop and
Kodak Imaging.


Wm.

Dear Wm

Thank for reporting this interesting problem. We do not have any other reports
of an image actually making the machine reboot. We would be very pleased to get
hold of that image so that we can analyse its properties. However, 78Mb will be
too large to e-mail.

There is a definite possibility that your computer is running out of memory.
Although the file size of the image is 78Mb, it is stored with compression and
the actual uncompressed size could easily be 10 times bigger when loaded into
memory.

We would suggest that 256Mb memory is too small for general image processing.
Your Windows OS will be taking at least 100Mb of that, and likely 200Mb, leaving
you very little for your applications. We would recommend you consider upgrading
to 1 or 2Gb, being that memory costs about $10 per Gb these days.

Best regards

Adding additional memory is not as simple as mentioned. For have a few extra
chips in closet right now and these could have been installed in ten minutes.

Problem being is that certain motherboards or CPUs will not accept additional
mamory, no matter at what cost. H-P products seem to follow this trend now, in
that if you read their manual, it will cite just how much can be installed. The
slots may be there, but once the count gets up high enough, it quits accepting
more. If for example your documentation says no more than about 256 and you
install 1 Gig, then it will quit at at the noted amount, and refuse remainder.
Watch at POST count up, and see how many are being used.

More memory is not always the solution.

Wm.
