We should implement "Back" and "Forward" menu items to be able to get back to earlier zoom settings easily. The following shortcut keys should also be implemented:

Back -> Alt + Left arrow
Forward -> Alt + Right arrow

The "Zoom To Initial extent" should now be implemented as getting back to the beginning of the history.

Set the Map scale for a smaller value e.g. from 30227 to 30000 and push the Apply button.

All the symbol definitions are missing from the map file and due to this you get an error message:

The consequence is very similar to the phemomenon of the issue #22.

Trying to select a point feature does not work if the ANGLE is not 0 in map file.

The coordinates of the same point with 0 degree rotation are:
256443 5212654
but with a 90 degree rotation they are:
256553 5212559
with a 1454 zoom value (though I used the pawn cursor for getting these coordinates, these differents are too great)

Result of the selection without rotation

The selecting with 90 degree rotation

Result of the selection with 90 degree rotation

In mapserver.h (row 1006) we can see the styleObj struct has offsetx and offsety. They are double.

mapserver.h

struct styleObj{
...
double offsetx, offsety; /* for shadows, hollow symbols, etc... */
...
}

According to this we can see in mapfile.c (row 2726 and 2736) they are treated as doubles when they are loaded in.

mapfile.c

int loadStyle(styleObj *style)
{
...
case(OFFSET):
if((symbol = getSymbol(2, MS_NUMBER,MS_BINDING)) == -1) return(MS_FAILURE);
if(symbol == MS_NUMBER)
style->offsetx = (double) msyynumber;
else {
...
if(symbol == MS_NUMBER)
style->offsety = (double) msyynumber;
else {
...
}

But in mapfile.c (row 2986) the style is saved by a writeDimension (mapfile.c row 525) function which wait ints on its 4th and 5th operands
that is why the OFFSET value of styleObj losts the precision of double when the map file is saved.

mapfile.c

...

static void writeDimension(FILE *stream, int indent, const char *name, int x, int y, char *bind_x, char *bind_y)
{
writeIndent(stream, ++indent);
if(bind_x) msIO_fprintf(stream, "%s [%s] ", name, bind_x);
else msIO_fprintf(stream, "%s %d ", name, x);
if(bind_y) msIO_fprintf(stream, "[%s]\n", bind_y);
else msIO_fprintf(stream, "%d\n", y);
}

...

void writeStyle(FILE *stream, int indent, styleObj *style)
{
...
writeDimension(stream, indent, "OFFSET", style->offsetx, style->offsety, style->bindings[MS_STYLE_BINDING_OFFSET_X].item, style->bindings[MS_STYLE_BINDING_OFFSET_Y].item);
...
}

The solution for this issue could be anther writeDimension function with 2 double operands.

If you edit the map file with Notepad++ and save it after setting the SYMBOLSET path relative to the map file.
(That is there is not a symbol file in the folder of the exe)

Open the map file in Map Manager and you will see that the inline symbols are not loaded.
If someone saves the map file (no noticing that the file was wrongly loaded) than he will lose all his inline symbol definitions.

MapManager does not support mapfiles saved with uft-8 encoding.
Opens a mapfile in utf-8 and displays fine. But changing, for example, the filter query, will not encode characters correctly and corrupt the mapfile.

When I try to open a mapfile with PROJECTION set to "init=epsg:900913" the following error is thrown:

I try to add the projection definition in c:\Program Files (x86)\MapManager\ProjLib\epsg file but without success.

#900913
<900913> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids= <at> null +no_defs <>

Creating symbol definitions by code and saving by mapObj's save function you will find that loading in Map Manager the definitions look like this one:

SYMBOL
NAME "120"
TYPE TRUETYPE
CHARACTER ""
FONT "TC2A"
END

So the character is missing but opening the file with Notepad++ you can see an "HTJ" with black background color:

SYMBOL
NAME "120"
TYPE TRUETYPE
CHARACTER "�"
FONT "TC2A"
END

If you edit the map file and change the character to for example to "6" and see the map and nothing changes you will see the same sign as it was when you loaded in the map file. If you save it still there is not different but if you look the map file in Notepad++ you will see that:

SYMBOL
NAME "120"
TYPE TRUETYPE
CHARACTER "�6"
FONT "TC2A"
END

Anyway if the SYMBOLSET path pointing to a folder where is not the looked-for file than you will see:

SYMBOL
NAME "120"
TYPE TRUETYPE
CHARACTER "‰"
FONT "TC2A"
END

Which differs from the "".

The Map Server can handle the relative path to font.list and to the symbolset from the map.file.

The Map Manager does not allow to save a map file with a relative font.list path (FONTSET). That makes the software unflexible.

Set ANGLE 90 for the rotation of the map in the map file!

Choose the Pan function due to move the map by drag-and-drop!

If you try to move the map to the north with a downward directed drag-and-drop operation than the map move to the east with the same distance.

The blue cross show the center of the screen.

why new version of MapManager is not published on git?
present version is 2-3 years old

Alpha values has been introduced in the colorObj constructor, the earlier setting causes fully transparent colors everywhere.

IndividualValuesTheme should allow to specify classitem instead of expression

The following enhancements should be added:

1. Add context menu to select list, implement "Center To Shape", "Go To Layer (Text)", "Go To Class (Text)"
2. Add center marker (cross)

By retrieving the pixel buffer directly and not using png/jpg encoding

Select 3 features (the first 3 in the list on the left):

Drag the 3rd in the row over the 1st one and you will see:

In this first permutation we can see that the Road became Train, the Highway became Road and the Train became Highway.
Now do the same again (put the third to the first place):

In the second permutation the Road became Highway, the Highway became Train and the Train became Road.
Now if you do the same again you will see everything get back to the first original situation

If I have a shapefile with an attribute field 'fclass' I would like to create as many sub-classes as there are unique values.

Ideally I would like the rendering to be set to that of the parent initially.

Querying DEM pixels works successfully until you add another layer into the mapfile.
Basically if you just have the DEM layer you can do a select and it works, if there is another layer selectable you get the error

To create large mapfiles as simple as possible, I frequently incorporate include as :

INCLUDE "../ec/connec_db_pg.map"

Does MapManager can manage them?
I know, that it's more a question than an issue.

The download links listed at https://github.com/DMS-Aus/MapManager#downloads result in a 404 Not Found error.

I have downloaded and installed MapManager 1.1 from https://www.gisinternals.com/mapmanager.html, but when I tried to open an ECW image, I encountered an error. I see there is GDAL ECW driver mentioned at https://github.com/DMS-Aus/MapManager#downloads and hoped that this would enable MapManager to support ECW images, but the link is broken.

I'm using mapmanger version:
MapServer version 7.0.1
GDAL 2.1.0, released 2016/04/25
proj Rel. 4.8.0, 6 March 2012
geos 3.4.3-CAPI-1.8.3 r4038
zlib 1.2.3
libcurl/7.37.1 OpenSSL/1.0.1h zlib/1.2.3

I'm not able to make a fill patterns other than defaults (ex. Horizontal-1).
See the images attached to this issue.
Please correct me if I'm wrong

Many thanks
Michele

This is wrong:

This is ok:

Trying to open a vector file in a folder named with accentuated letters you will get the following error message:

Hi

Using the mapmanger.mis.exe on windows 10 home edition, displays a message stating this software
cannot run on this PC. Will there be a version to run on windows 10 home edition?
If not what is required to compile the software on windows 10 home edition?

Thanks

Steps to replicate:

1. Create empty map file
2. Add a shapefile without a PROJ

Hi,

What about the folks out there with no Visual Studio, i.e. can we have a linux port please?

Cheers

After saving a map file containing TRUETYPE symbol definitions with ANCHORPOINT, the anchorpoint is missing:

Example: Before save
SYMBOL
NAME "2"
TYPE TRUETYPE
CHARACTER "A"
ANCHORPOINT 0 1
FONT "alfa"
END

After save
SYMBOL
NAME "2"
TYPE TRUETYPE
CHARACTER "A"
FONT "alfa"
END

The same phenomenon occurs when I switch to the map and back to the text of the map file.
That is why I cannot use anchorpoint with this kind of Symbols, but for example with VECTOR type symbols everything works well.

Hi @szekerest how are you ?
Do you have an example map file to style OGR layer ?
Eg. if I open a DXF file in MapManager, how do I target and style the layer ?

  LAYER
    CONNECTION "dxf1.dxf"
    CONNECTIONTYPE OGR
    NAME "line"
    PROCESSING "GETSHAPE_STYLE_ITEMS=all"
    STATUS ON
    TEMPLATE "query.html"
    TILEITEM "location"
    TYPE LINE
    UNITS METERS
    CLASS
      NAME "Class (0)"
      STYLE
        COLOR 0 0 0
        SIZE 8
      END # STYLE
      TEMPLATE "query.html"
    END # CLASS
    CLASS
      NAME "Class (1)"
      STYLE
        COLOR 0 0 0
      END # STYLE
    END # CLASS
  END # LAYER

ogrinfo output:

OGRFeature(entities):224
  Layer (String) = STOCKPILES
  SubClasses (String) = AcDbEntity:AcDbPolyline
  Linetype (String) = VULCAN_LINE_TYPE_1
  EntityHandle (String) = BFC
  Style = PEN(c:#ffbb00,w:0.3g,p:"0.024g 0.072g")
  LINESTRING Z (1 1 411,2 2 411,3 3 411,4 4  411)

This would help to eliminate the design time issues
Expose syntax color settings to program options.
