| Easy Trace
for DOS FAQ
|
| Easy Trace under Windows XP works only
in demo-mode. |
 |
| New drivers HASP (HINSTALL.EXE) are necessary for
work under Windows XP. You may download them from www.aks.ru
or ftp://ftp.aladdin.ru/pub/HASP/Upgrade/hinstall.exe.
For installation of new drivers, it is necessary to start the utility
with the key i:
HINSTALL -i.
BUT:
It should be mentioned that Easy Trace has not been tested yet under
XP. Microsoft doesn`t guarantee full compatibility of applications
written for earlier versions of Win32 with XP.
|
| |
| Why was the installation under Windows
2000 interrupted without any error message? |
| We have noticed the only situation when Microsoft
InstallShield behaves in that way - when there are spaces in the
name of the Windows temporary folder. So, you may act as following
to solve the problem:
1. Create a folder without spaces in the path, C:\TEMP for example.
2. Click: My Computer - Properties \ Advanced tab \
Environment variables button
3. In the "System variables" pane, enter the value of
the TEMP and TMP variables equal to one specified before (e.g. C:\TEMP).
Easy Trace installation should be successful now after you have
closed all the windows (including ones of the Explorer). |
| |
| Why was the installation interrupted
with the message " An error occurred during the move data process:
132"? |
| Too large disk partition may be one of the reasons.
Try to install the program on a smaller one. |
| |
| How can I use ET at processing of maps
on the scale 1:200 000, 1: 500 000 or smaller? |
| Easy Trace v 7.0 Pro already gives the opportunity
of such small-scale map processing. As the program does not work with
geographic coordinates directly, you should choose conventional units
(pixels) at project creating, vectorize the map "as it is",
and make geo-positioning in your target GIS. |
| |
| In prior versions the SHIFT key
could be successfully used for the qualitative snapping of the object
to the nearest point (to a vertex of another object, etc.). Now the
program generates a new vertex at snapping. Please explain what should
I do to snap the object to the specified point. |
 |
Beginning with v.6.5, the functions of the SHIFT/CTRL
keys as well as the principle of arc-node model creation were changed.
Now snapping is considered from two points of view:
- what is being generated (node/vertex);
- where it is being generated (at existent / new vertex).
Both at manual or automatic input/editing of vector objects, WHAT
IS BEING GENERATED is specified in the TopologySettings
dialog box (the Project menu). If no rules are specified
in the Extended tracer rules dialog box, then in the manual
mode you may use the SHIFT key to form a common vertex or
the CTRL key to form a node.
To snap an object to an existing vertex, click this vertex directly
(vertex size is specified in the View tab of the Project
parameters dialog box). Otherwise a new vertex/node will be
generated. |
| |
| What should I do if the current Easy Trace
version does not support the format of my rasters (e.g. Hitachi Raster
Format - HRF)? |
 |
| You may transform rasters you have into the formats
which Easy Trace supports using third-party utilities. HandmadeSoft
Image Alchemy v.1.11 (http://www.handmadesw.com/)
-- 4.1M/4.6M for PC (demo) is one of this kind. Demo-version has
restrictions on the maximal raster size. |
| |
| What does the message mean: "Resources
required for current command execution exceed abilities of demo-mode
!"? What should I do in this case to continue normal work with
the program? |
 |
| This situation may arise because of several reasons.
- Absence of the hardware key. Check whether the hardware key
is plugged in your computer.
- Termination of the Free Upgrade period. Your hardware key must
operate with all the releases during a one-year term since the
purchase day. If this term has expired but you need a new version,
contact us for paid Upgrade.
- Loss of memory or physical fault of the hardware key. If the
foregoing requirements are kept, then, most likely, the reason
is program's failure in identifying the hardware key. To solve
this problem contact the developers.

| How to process maps in projections different
from the "Plan" one? |
 |
| Unfortunately, the current Easy Trace version can
not support geographical projections directly, i.e. coordinates
can not be input in latitude and longitude degrees. Nevertheless,
you may vectorize maps, but that requires additional efforts. Following
is the algorithm of such material processing.
- Source map scanning. There are no restrictions here. You may
scan paperware directly under Easy Trace, or using any other external
software. At this stage you should obtain at least rasters covering
one topographical sheet. But several will be better.
- Preparation for text information snapping. First of all we would
like to note, that suggested method of operation with geographical
projections is directly connected with GIS, you prepare data for.
I.e., obtained vector information, linked using this method, will
be "accurately linked" only while export into your GIS.
Well, specify the projection and map scale you deal with, load
GIS and start geo-grid creation. You need to specify points in
nodes of this grid. Besides, it is desirable to perform this operation
regularly. For example, from left to right and top-down. It is
advisable to make a table of correspondence of point numbers (at
input succession) to their coordinate. Then save the specified
file and import it into the preliminary prepared Easy Trace project.
This Easy Trace project should have conventional units as units
of measurement and 1:1 scale. While import, you should necessarily
switch on the "Expand vector area if necessary" option.
If everything was done correctly, the similarity of your geo-grid
previously created in GIS appears in Easy Trace window. Save the
Easy Trace project and export it into CSV format. The export should
result in text file with the CSV extension. Change its extension
for DAT and jump to the following stage.
- Raster data adding. Open the Easy Trace project with the imported
geo-grid. Start adding raster by arbitrary set of reference points.
When the raster will be displayed, you will be prompted to input
real reference points (grid nodes) coordinates and show their
screen position. But you can't input coordinates in degrees. Don't
worry. Press the "load" button and specify there the
preliminary created text file with points (former CSV). If everything
is correct, the table with points coordinates will be filled and
the point number will be equal to points number in the grid. You
will have to specify nodal points on map and add raster. Not to
be mistaken, specify points regularly, in the same way as during
grid creating in GIS. If the point is specified correctly, the
error indicated in table will be within reasonable limits (from
0 to 10 c.u.).
The suggested method may seem to be difficult. However, it is not
so. You will be able to get used to it quickly and, may be, simplify
it. |

| The source image colors are distorted when
I merge two index rasters. For example, black pixels sometimes become
light blue, even white. Source files are PCX, 256 or 16 colors. |
 |
| Your problem is that you try to merge index rasters
(256 colors) of different palettes. I.e., index 1 in one raster
is black, and in another - red. There are several ways to solve
this problem:
1) Scan in the truecolor mode, e.g. 65535 colors (16 bit). Only
two times more information, but you will have no obstacles.
2) Convert your raster into the truecolor mode before merging, and
then backwards. The Rainbow module can perform this operation.
3) Use the same palette to scan all the fragments. The question
is that the scanner in any case receives truecolor information and
then creates palette for it. You may scan a part of a map, and then
use its palette. You may also select the system palette.
4) Scan the map in parts. Add the rasters to the project and then
execute the raster merging utility. It results in palette averaging.
We should recommend the second variant. Truecolor rasters contain
maximum information. If you have them you may be sure, that you
won't scan them for the second time. |

| Why Rainbow and Starter hardware keys are
"not transparent"? If both keys are plugged in, either Trace
or Rainbow do not operate depending on location. |
 |
| Indeed, the Rainbow and Starter keys are mutually
"not transparent". If you need the Rainbow component for
joint operation with Starter Kit, you should update your key. In
this case you'll save some money, as the price of such a package
is cheaper than buying of two separate keys. We actually have not
provided the ability to buy these two products as independent packages
to be used on the same computer. |
| |
| While Easy Trace v 7.0 Pro installation
under NT or Windows 2000 some problems occur. Under Win98 the installation
runs without any difficulties. Error text is error.zip. What is the
matter? |
 |
| Such a mistake may occur if you have launched the
installer twice by mistake or started installation during an Easy
Trace session. Another possible reason - an attempt to ovewrite
an old version by the new one. You should UNINSTALL the previous
version CORRECTLY beforehand. |
| |
| Sometimes it is necessary to see a color
raster while vectorization to know the tracers location on the
map. How can I switch between rasters quickly? |
 |
| There are the following ways to change raster substrate:
a) You may see color substrate and black-and-white layers simultaneously.
You should switch on the <Service>\<Parameters>\<Transparent
black-and-white rasters> option;
b) You may use "hot keys" Alt+1, 2
etc. to switch
on/off raster layers quickly;
c) Beginning with the 6.5 version, pressing the right mouse button
and holding down the Ctrl key simultaneously display context menu
for raster layer processing. You may select raster layers in it
to be switched on/off. |
| |
| Processing the tablets of a manufacturing
firm, I have to deal with a great number of communication lines. Can
you advise me the quickest way to vectorize such lines? |
 |
| First of all, technological communications are
usually represented as broken or direct lines. That is why you should
use the linearizing tracer for semiautomatic vectorization. Specify
the strategy with the following parameters: permissible line gap
is 40-50px, continuation search cone is 10-15 degrees, ignore segments
up to 20-30px, depth of search for continuation is 35-40px. These
parameter values allow the tracer to run through alphabetic characters
on the lines without any delay on them and not to consider them
as possible continuations at a fork. And the search cone small value
will make the tracer to look only forward and not to turn to the
neighboring lines.
Secondly, use the definition of user line types (<Project>\<Line
Types>) for the convenience of visual control. You may also import
line description from AutoCAD (LIN format), or define them directly
in Easy Trace, replacing the existing prototypes for required values. |
| |
| How can I vectorize a great number of
similar objects (houses, constructions, etc.) with Easy Trace? |
 |
| It is convenient to use blocks in projects with
a great number of recurrent point or linear objects. The set of
blocks may be inherited from a prototype, when creating a prototype-based
project, or obtained at import of DXF-file heading. If you want
to create some blocks directly in Easy Trace, act as following:
- digitize the object that will be later used as a block;
- select this object with the group editor;
- from the group editor submenu select the "Include the selected
primitives into block" command;
- in the "Parameters for block definition" dialog box that appears
specify the new block name and the layer this object will be attributed
to. The block name should be unique in the project. That is why
there is a list of existing blocks in this dialog box that prevents
you from reuse of existing block names.
Before vector data export into the target GIS, you may explode blocks
into primitives, the initial object consisted of. For that you should
select the "Explode blocks" command from the Utilities
menu and in the dialog box that appears, specify the required parameters. |
| |
| Can the description of the Easy Trace
(jet) file be obtained? |
 |
| Unfortunately, *.Jet is our internal binary format
and we are not planning to public its description in the near future
because of our desire to reserve the right for its change. |
| |
| How can I send the vectorized raster (layers
obtained after vectorization) into "MapInfo" GIS correctly? |
 |
| For export into MapInfo it is enough to use the
"Export" command. You should attentively think over export options,
as if you have not selected layers for export you wouldn't receive
any file. MapInfo data structure requires each layer to be exported
into separate file. You will find the "project layers to exported
file correspondence" table on the "MIF Options" tab of the
"Export" dialog box. |
| |
| What should I do if I need to vectorize
adjacent sheets in one project without merging them? |
 |
| You may process separate map sheets (without merging
them) in the following way:
1. Create base project (project-prototype), and create in it all
the necessary layers, conventional signs as well as specify all
other settings required for your project.
2. Then for every new raster (or map sheet) create a prototype-based
project, changing only coordinates and the raster being vectorized.
3. When all the map sheets are vectorized separately, they may be
merged as vector data. To do it, import all your vector data in
turn into the same project, and then use the "Line Ends Joining"
command and join line ends along the specified boundaries. |
| |
| After source map scanning in Easy Trace
the tracing tools are unavailable. One can use only raster editing
tools. |
 |
| You are quite right - after raster scanning only
raster editing tools are available. That happens because Easy Trace
supports two types of documents: raster and vector ones. After scanning
or loading of a raster, the program operates with a raster document.
For further vectorization you need to create a vector document.
For this purpose you should use the "File/New Project"
command. And then you should add raster information to this project
with the help of the "Project/ Add Raster" command. |
| |
| Please, explain in details, what does
the "Coordinate transformation" option mean while export
in MapInfo format. |
 |
| You should register in MapInfo the raster your
Easy Trace project is based on. While this raster-based project
export select the "Coordinate transformation" option and
specify the world TAB file of the foregoing raster. The exported
data will have the same projection as the raster registered in MapInfo
. |

| Problems occur with hardware key under
Windows NT 4.0. What should I do? |
 |
| In the new HASP driver the problems occuring under
Windows NT 4.0 are eliminated. Due to continuous
updating of Windows NT, the old protective key driver may operate
incorrectly after installation of SP 4 and SP 5.
The new HASP driver has been tested to work under Windows NT
up to SP 5. For detailed information see www.hasp.com |
