[MI-L] Clip region bloats PDF
Greetings List, I've never really noticed this before until tonight when I needed to email a PDF to a client. The workspace happens to have a clip region set and I've found this bloats the otherwise casual 28kb layout PDF to just over 1mb. Ok, I fell back and punted and just clipped my own region in the cosmetic layer. Doesn't look quite as pretty and I had to delete several dynamic labels that still showed. Is there some setting, or other solution around this PDF bloat when a clip region is active? MI v6.5 by the way. Thanks, Dave -- Outgoing mail is certified Virus Free Checked by AVG Free Edition.

[MI-L] Quality of area calculations and Elementary Statistics
Hi List
I need to create a statement of the probable error of the area of a
polygon where the coordinates have a standard deviation of 2m (SD=2
say).
Given the tools available in MI, how far wrong is buffering the object
by 3 x SD (99% confidence), subtracting off the MI computed area of the
original and saying that this is a 99% confidence value of the area?
A further tweak on the problem is overlapping a region with coordinate
of SD 2 against a region of coordinate of SD 5 (2 different data sets)
and giving an estimate of the quality of the overlap?
Any help would be appreciated
Tony
Given below is the C code snippet for area calculation. Classically I
should determine the expectations for each sub polygon.
=
//
// Measure the polygon area
//
//
// A[i]=(poly[i].x - poly[i-1].x)*(poly[i].y +
poly[i-1].y)/2.F;
// Differentiate twice to get expectations
//
longMeasure_Polygon_Area(double *poly_area,dPoint2D *poly,long
poly_count)
{
longi;
double total=0.F;
*poly_area=0.F;
if (poly_count 3) return 0L;
for(i=1;ipoly_count;i++)
{
total += (poly[i].x - poly[i-1].x)*
(poly[i].y + poly[i-1].y)/2.F;
}
total += (poly[0].x - poly[poly_count-1].x)*
(poly[0].y+poly[poly_count-1].y)/2.F;
if(total 0.) total *= (-1.);
*poly_area=total;
return 1L;

Re: [MI-L] Clip region bloats PDF
David, The clip region functionality is enabled with three choices that you can find in the Map Options dialog. These are called Windows device clipping, Windows device clipping (no points or text) and Erase Outside (no points or text). They all will have different impacts on the size of data sent to print which in your case is to a PDF file. The Windows device clipping is the default and simply means that we take your clip region and pass it along to Windows to clip at the device level. This is usually the fastest way to do things. The clipping happens graphically so text, line styles, fills and symbols are clipped wherever they fall. The implementation is out of our hands ;that is Windows or even a particular driver is free to do this as it sees fit. In general most devices simply remember the clip region and handle the clipping at display time. What this means is that all the data that would have normally been sent to the device is remembered as well as the clip region itself. If the clip region itself is dense, it could easily add to the total . If you had an expectation that the clipped data is not being stored, that would also be wrong. The Erase Outside option is our oldest method of implementing this feature. It goes back to Version 4 (1995), I believe. This method uses the Erase Outside object processing code to eliminate the actual spatial data outside the clip region. As text glyphs and symbol fonts are graphic and not spatial data, these objects are simply skipped. It was originally felt better to skip them than cut some of them in half. The same also goes for wide line styles! Basically, the clipping is done at the object processing level. This might solve your problem but depending on the complexity of your data, could be much slower to print to the .PDF and draw on screen. Neither the data outside the region nor the clip region itself is stored. If the clip region is complex, the boundaries that it intersects will inherit the complexity of the clip edge just like in object processing. The other option is simply a way we added to get the similar behavior to the object processing method but much faster to draw. It uses the same technology as device clipping but purposely skips points and text to be compatible with the old behavior. I have no idea if this is much used but it will not help you reduce the size of the .PDF. It will almost certainly increase it. It is also possible that you are using this option as a default which could be your answer right there! This feature is set in each map window but is initialized by a preference. It is possible that you have this set. I hope this helps.

[MI-L] RE: Labels
Hi, I've also had this problem and it wasn't caused by packing -- the arrows from the labels point to the correct points (correct label with correct point) and I haven't packed the table. Not sure if it is caused by coordsys difference. The labels aren't really in the wrong place -- the lines/arrows pointing from the label to the point are hundreds of miles long (I've had one go almost to South America when the point was in Central Florida). For example, I have a map layer with an extent of 20 miles and have a few labels pulled off some points, maybe 1/2 a mile from the point -- just enough so it is readable in my layout window. I re-open the saved workspace and those labels are now hundreds of miles away from their points. If it was a coordsys problem, should I expect the difference to be the distance between a point in one coordsys and the same point in another system? Or is the coordsys difference just causing the labels lines to fly all over the place? Arlene Arlene Baker The Shopping Center Group 2170 W.

This problem is not only related to packed tables. I can slo be related to raster layers ... Imagine this: 1. You have a map with a bunch of layers and a raster layer. Thie raster layer is not visible, but in a different coordsys 2. You save a workspace with the current view of the map, the coordsys is not the same as the raster layer 3. You reopen the workspace. Now it gets technical: 3a. When a map is created thru a workspace MapInfo starts by adding all the layers 3b When it has added the layers, the map window has the coordsys of the raster layer 3c. Now the settings for the layers are applied, and also the costum labels - coordinates are not using the coordsys of the raster layer 3d. Finally the settings for the raster layer, se the zoom level and turns off the raster layers visibility 4d. Now the labels turn up in incorrect positions. Did you notice the problem ? The problem is that when saving the workspace, the coordsys is not the same as when reloading the workspace again. This might interfer with the position of the labels - and I guess also with cosmetic objects !? So, be aware when using raster layers in a different coordys then the rest of you layers. BTW, this might be solved with MapInfo 8.5 as you here can reproject raster layers. Peter Horsbøll Møller GIS Developer, MTM Geographical Information IT COWI A/S Odensevej 95 DK-5260 Odense S.

RE: [MI-L] RE: Labels
Title: RE: [MI-L] RE: Labels Arlene, I'm not sure, what is causing your problem and if it is the same problem. The problem I have encountered was that the labels were moved approx. 300 meters. This matched exactly the difference between coordinates in two often used coordinatesystems in Denmark. The problem was that when the workspace was written the coordinates were written using the first coordinatesystem. But when the workspace was reloaded, the coordinates were interpretered using the second coordinatesystem. If you look at a workspace in a text editor, you'll see that when MapInfo creates a map, it involved a number of statements: 1. Create the Map with the layers. Map From list_of_layers ... 2. Set coordinatesystem, center and zoom Set Map CoordSys ... 3. Setup the layers Set Map Layer 1 ... Layer 2 Layer ... If you add a print statement, that prints the current coordinatesystem of the map after the first Set Map and after the second Set Map, you can see if MapInfo is using different coordinateystems. The print statement is this: Print MapperInfo(FrontWindow(), 18) Here is a short sample: ** ...

Re: [MI-L] Bringing in a .shp file
Hi Tammy, Further to what Mike just suggested, you could also go to Tools Universal Translator Universal Translator and fill in the dialog box. The difference between the two methods is that with File Open, you can only view the file, whereas the Universal Translator "breaks the link" to the original SHP file and creates a new copy in native MapInfo format. The advantage this way is that you can edit the table, update data in the Browser, etc. Note though that both methods will not bring across any colours associated with the polygons. There is a company in Queensland that has a third party MBX that will do this, but I can't remember their details.
