Myrdrv.ini Userguide

IGC applications (MYRIAD®, Net-It® Central, and Brava! ® software) recognize supported file formats, their file extensions, and any related parameters through the Myrdrv.ini configuration.  For all sections except [idrivers] and [edrivers], the actual settings are at the end of the section, following the explanation of the parameters and their values.  Lines preceded by a pound sign (#) are ignored by the applications, such as the lines of explanation.  Unless otherwise noted, all settings are in the following format:
Format:	Parameter=VALUE
Example:	ParseDXFExtents=OFF
The following sections are in the Myrdrv.ini file (any sections not listed in this document should not be modified by the user):

[idrivers] 
The [idrivers] section identifies and maps file extensions to their specific import driver.  You can change, add, or remove file extensions in this section.  The format for this section is shown below.
EXT=G, Path\Driver_name, "Description"
where EXT is the two or three character file extension used to identify the file type and G is the letter indicating the kind of file:
	G	= 	Graphical 
	H 	= 	Hybrid 
	F 	= 	Folder
	M 	= 	Markup
	T	=	Text
	S	=	System
Path\driver_name	The path and filename of the actual driver.  The path is not necessary if the driver is located in the application’s executable directory.
"Description"	A description of the type of format the driver handles, generally, but not always, beginning with the extension.  This must be surrounded by quotes and include spaces.
Example: dwg=G,myridwg.dll, “DWG AutoCad Drawing”

[loader-specific display options]

This section allows certain display option defaults to be set according to specific loaders. The following display option keys are entered into this section, followed by a list of loaders.

Example:

DisabledColorConflictResolution=myriinso.dll,myriswdwg.dll	

In this example, Outside In and SLDDRW files load with the “Color Conflict Resolution” feature turned off by default.

CADColorScheme=0,15,myridwg.dll,myridwf.dll,myrime10.dll,myridgn.dll

In this example, the listed CAD files (DWG, DWF, ME10, and DGN) load with the following default color scheme:
0 is the color index used for the background color (0=black)
15 is the color index to use for the foreground color (15=white)

The background index refers to the list of colors defined in the [Background Palette] section of the myriad32.ini. The three valid indexes are 0, 1, and 2.
The foreground index refers to the list of colors defined in the [Foreground Palette] section of the myriad32.ini file. The valid index range is 0 through 15. The foreground color index only affects black and white raster files. Vector files are not affected as each line in a vector file has its own color definition.

[CAD]
(This section is applicable to MYRIAD only.)
This section explains and sets DXF and DWG driver configuration parameters.  Descriptions of parameters and their setting options are shown on the following page.
DXF and DWG
OutputAttributes	Tells the application whether or not to sense image attributes. 
OFF	=	Do not sense attributes
ON	=	(Default) Sense attributes
ShxAbort	Tells the application whether or not to abort if a font file cannot be found. 
Note: This setting can be edited in the Paths tab of the Options dialog box.
WARN	=	(Default) Display missing files in a dialog box 
ABORT	=	Stop opening document and informs user file not found
IGNORE	=	Continue opening document without displaying missing file list
ShxPath	Specifies the path for the loader to search for font files. A semicolon is used as the path separator. 
Note: This setting can be edited in the Paths tab of the Options dialog box.
XrefAbort	Tells the application whether or not to abort if a cross-referenced file cannot be found. 
Note: This setting can be edited in the Paths tab of the Options dialog box.
WARN	=	(Default) Display missing files in a dialog box 
ABORT	=	Stop opening document and informs user file not found
IGNORE	=	Continue opening document without displaying missing file list
XrefPath	Specifies the path for the loader to search for the cross-referenced files. A semicolon is used as the path separator. Note: This setting can be edited in the Paths tab of the Options dialog box.
ThawAllLayers	Makes all frozen layers visible.
FALSE	=	(Default) Frozen layers invisible
TRUE	=	Frozen layers visible
Accuracy	The valid range for accuracy is 0.0 to 5.0.  The default is 0.75.
MaxCircleSegs	The valid range for the length of circle segments is 0 to 64000.  The default is 128.
WhiteToBlack	Converts white lines to black lines.
FALSE	=	(Default) White lines
TRUE	=	White lines to black lines
MaxFileBuffers	Maximum number of DWG or DXF files you can have opened at once.  You can have more files open of other file types.
TagOrPrompt	Specifies whether the attributes tag or prompt is shown for intelligent objects. This also applies to DDE requests for attributes.
TAG	=	Show tag information
PROMPT	=	Show prompt information

FillTTF 	Specifies whether to fill True Type fonts used in CAD files. Note: If this driver is run in Myriad versions prior to 7.0, this value will not be in the ini file and text will be rendered as lines instead of incorrect polygons.	
TRUE		=	(Default) Type fonts are filled.
FALSE		=	True Type fonts are stroked.

ParseDxfExtents	Specifies for the myridwg.dll driver to pre-parse the DXF file for viewing at extents. The majority of DXF files do not display the correct initial extents so the default of this setting is ON to allow the IGC driver (myridwg.dll) to parse through the file and calculate the minimum extents. This slightly increases processing time.
ON		=	(Default) Parse DXF files for extents.
OFF		=	Do not parse DXF files for extents.

ParseDwgExtents	Specifies for the myridwg.dll driver to pre-parse the DWG file for viewing at extents. Typically, the extents provided by AutoCad are larger than the extents calculated by the IGC driver (myridwg.dll). A DWG file that is viewed at extents will appear smaller when this parameter is set to the default of OFF. You should turn this setting to ON if you are viewing drawings that do not view with the correct extents – usually older or corrupt DWG files.
ON		=	Parse DWG files for extents.
OFF		=	(Default) Do not parse DWG files for extents.

proja=<drive>:\files\myproja\dgn
LoadReference	Indicates whether or not to load reference files. 
OFF	=	Does not load reference files
ON	=	(Default) Load reference files
The loader searches reference files in the following order:
1.	If the filename contains the project macro, then the loader uses myrdgn.cfg to expand the macro. 
2.	The loader searches the full path name specified in the DGN file. 
3.	Uses RFDIR for environment variables, if any exist. 
RefAbort	Tells the application whether or not to abort if reference files cannot be found. Note: This setting can be edited in the Paths tab of the Options dialog box.
WARN	=	(Default) Continue loading and warn the user that the file won’t be loaded 
ABORT	=	Abort the file load action. Stop opening document and inform user file not found
RFDIR	Tells the loader where to look for reference files.  If no path is specified, it searches the Windows path. 
FontPath	Specifies the path for the loader to search for the DGN font files. If no path is given, the loader searches the directory where the application is located. The DGN_Fonts directory is included in the MYRIAD installation.
WindowsRenderer	Indicates that you are running on a Windows operating system.
1 = yes (Required for DGN version 8 or greater support.)
2 = no
Example:

[HPGL]
This section explains and sets the HPGL driver configuration parameters for the pen width, color and clipping planes.  
PenUnits	Sets the measurement for the pen widths.
INCH	=	Inches
MM	=	(Default) Millimeters 
OverridePens	Use pen settings from the file if found
TRUE	=	Use file settings if found
FALSE	=	Use PenUnits settings
The predefined colors and pen widths are specified in a table, as shown in the example below.

Pen015=	0,	0,	0,	0	(Black)

[DG]
This section sets the DG driver configuration parameters for pen colors.  The format and values are the same as the HPGL and 906/907 driver configuration shown above.  The predefined colors and pen widths are shown in the following example.
Example: 
Pen#		R	G	B	Color
Pen000=	192,	192,	192	(Gray - default background)

Pen015=	0,	0,	0	(Black)

[ME10]
The [ME10] section explains and sets ME10 driver configuration parameters, specifying font files and locations.  
FontAbort	Tells the application to abort if a font file cannot be found.
OFF	=	(Default) Continue loading
ON	=	Abort
FontPath	Tells the loader where to search for the font files.  If no path is given, the loader searches the directory where the application is located.
Font<n,n>	Specifies font parameters.  Each font is numbered 01 and 99 according to the following format.
Unix_filename, DOS_filename
 If no path is provided here, the path specified for FontPath in this section is used.  Unix and DOS paths are provided separately due to filename restrictions on DOS FAT drive partitions.  
LedArrowFill	Indicates whether the arrow head of LED entities are filled.
OFF	=	Not filled
ON	=	(Default) Filled
ShowCtrlPgon	Specifies whether the control polygon for splines display. 
OFF	=	(Default) Do not display
ON	=	Display
RequiredFont<n>	Specifies required fonts.  The format is the same as Font<nn>, except you can only use fonts 1 through 9.
PlotSizeForLinestyleAdjust	Specifies whether to adjust the line style for the paper size or per drawing unit.
<Size>	=	Indicate the page size (e.g., J) to adjust the linestyle.
U	=	(Default) Indicates for the application to base the linestyle pattern (e.g.,    - ) on the drawing unit.  By default, the application repeats the pattern only once per unit, though that can be set using the LineStyleRepeatFreq setting.
LineStyleRepeatFreq	Used in conjunction with PlotSizeForLinestyleAdjust = U, this specifies how many times the linestyle pattern should repeat per drawing unit.  The setting must be a number between .01 and 12 (the default is 1).  For example using LineStyleRepeatFreq = 2, the linestyle pattern    -  will be    -    -   per each drawing unit (it will be scaled down to fit within the drawing unit).  
Note:  	Because the pattern is scaled to fit the drawing unit, repeating the pattern in each unit may degrade the linestyle appearance.
UseDefaultFont	Indicates to use the font specified by the DefaultFont setting (see below) as the default ME10 font.  Any missing fonts are substituted with this font.  
Note:  	The default font may be a different size or character type than the missing font.  
ON	=	Use default font 
OFF	=	(Default) Do not substitute default font for missing font
DefaultFont	Specifies the font to substitute for missing fonts when UseDefaultFont is set to ON.  This must be set to the UNIX font name (see Font<n,n> above).  

[IGES_SECTION]
Do not modify this section.

[SOLIDWORKS_SECTION]
Filltext 	Specifies whether to fill fonts on SolidWorks 2D drawings.  Only fonts large enough to be filled are filled.  Filling fonts can affect performance. 
ON	=	Fill fonts
OFF	=	(Default) Do not fill fonts (use hollow fonts)

TextFillThreshold=(integer value between 0 and 100)	
Provides finer control over font filling. All text is filled that is larger or equal to the given value (measured in points). 

Example: 	TextFillThreshold=10
Any text that has a font point size of 10 or larger gets filled.  If the value is zero, everything gets filled. If the value is 100 nothing gets filled.
The default value of this field is 22.  Most text is smaller and therefore does not get filled.

AdjustTextForBoundingBox 
	Indicates whether or not the bounding box text adjustment code should be executed or not. 
TRUE	=	The text found in the drawing is checked to make sure it does not overlap the previous text entity.
FALSE	=	(Default) If set to false, or not present, the text is not checked and no box adjustment is done.
[Orcad_Section]
refAbort			Tells the application whether to abort if a font file cannot be found
				OFF = (Default) Continues loading
				ON = Aborts load and gives a warning back to the user 

[Auto-Recognize File Format Tests]
When the application tries to load a file with no extension or an undocumented extension (an extension which is not listed in Myrdrv.ini), the application tries to determine what file format it is.  The application reads a section of data from the beginning or header of the file, and then performs a series of pattern-matching tests on the data.  Each test has an extension and a confidence level associated with it.  If more than one test matches, the format extension used is the one associated with the highest confidence test.  If none of the tests succeeds, the standard application’s "Unrecognized Extension" dialog appears.
To Configure Tests  
This section contains a series of test entries in the format shown below (no spaces are required):
Format:	Testnumber=extension, start search offset, stop search offset, "search string", confidence
Example:	Test1=xyz,32,64,"\22XYZ\22\2CVersion 4.0",100
number = 	A number that differentiates the test from other tests.  The tests are performed in numerical order.  Putting tests with 100 confidence at the beginning of the list optimizes performance. See confidence below.
start search offset = 	The offset, from the beginning of the file, to start searching for the search string.
stop search offset = 	The offset, from the beginning of the file, to stop searching for the search string.  If you want to search only at one spot, set the start and stop offsets to the same number.
search string = 	A double quoted string, or byte pattern, to search for.  The string is case sensitive and may not contain a double quote("), a comma(,), a backslash(\), or any non-printable character.  To represent these values, use hexadecimal notation with no leading or following spaces.  For example:
comma = \2C
double quote = \22
backslash = \5C
number 13 = \0D
So, if you want to represent:  
"XYZ",Version 4.0
You need to enter:
\22XYZ\22\2CVersion 4.0	
confidence = 	A rating from 1 to 100.  The number represents the likelihood that success of the test indicates the truth of the format for the file.  If more than one test succeeds, then the test with the highest confidence is the deciding test.  If the confidence level is 100, the application stops testing and go with that answer.  Therefore, putting tests with 100 confidence at the beginning of the list optimizes performance.
Additional Options  
In the MYRIAD32.ini or Myruser.ini file there is a section called [Auto-Recognize File Format Options].  If the Prompt On Success parameter is set to TRUE the application asks the user if they want to load the file using the detected format or pick a different format themselves.  The default for this key is FALSE.

[Text]
This section controls the MYRIAD Text driver (Myritxt.dll).  This section does not exist in the Myrdrv.ini by default, but can be added by the user at any time.  The following options can be added:
Papersize	An alphanumeric string.  The default setting is Letter, but the following types can also be used:
Type	Width 	Height	Units
A	11.0	8.5	Inches
B	17.0	11.0	Inches
C	22.0	17.0	Inches
D	34.0	22.0	Inches
E	44.0	34.0	Inches
A0	1180.0	848.0	Millimeters
A1	848.0	594.0	Millimeters
A2	594.0	424.0	Millimeters
A3	424.0	297.0	Millimeters
A4	297.0	219.0	Millimeters
A4P	210.0	297.0	Millimeters
Letter	8.5	11.0	Inches
Legal	8.5	14.0	Inches
CharHeight	A decimal value indicating the height in points.   A larger value draws fewer characters per inch.  The default is 10.0.
CharWidth	A decimal value indicating the width in points.  The default is 1.414.
TabSpace	An integer value for the number of spaces to use for tabs.  The default is 8.
WordWrap	Indicates whether to use word wrapping or not.  The settings are TRUE or FALSE, with TRUE (use word wrapping) as the default.
Numbering	Indicates whether to number the pages.  The settings are TRUE or FALSE, with FALSE (no page numbers) as the default.
Margin	Decimal values (in millimeters) for each margin, in the following order:  left, right, top, bottom.  Use a space between each value, as shown in the example below:
Margin=72.0 72.0 36.0 36.0
UseFormFeed	Indicates whether to interpret or ignore the form feed character.  TRUE indicates to interpret it, FALSE (default) indicates to ignore it.

Product Specific Sections
The following sections are specific to Brava! Enterprise, Brava! Desktop, Net-It Enterprise, Net-It Now, and Net-It Central, and do not pertain to MYRIAD.

[cdl_section]
The [cdl_section] section sets general driver configuration parameters. 
ForceToJpg and JpgFidelity only affect PDF and published files (native application processed). With the following two parameters, you can force all color raster files to be written out as JPG. 
ForceToJpg		Tells the application whether to convert color raster files to JPG.
TRUE	=	All color raster files are converted to JPG format.
FALSE	=	(Default) Only JPG’s are written out as JPG.

JpgFidelity	Determines the file size and fidelity of the JPG file created by the PDF2DL  or publishing. Range is from 1-100 with 75 as the default.

MaxRasterDPI	Determines the maximum dots per inch (dpi) for raster images embedded in a CDL published file. Applies to documents converted from Office formats only. Images with a higher resolution than the specified DPI are re-sampled down and images with a lower resolution are not adjusted.
 
This setting can have a large impact on how small the CDL published file size
is, how quickly the file downloads, and how quickly it views/prints from the client software. The default setting is 600 dpi. If you require a higher dpi than 600, you MUST edit this value to set it higher.
For example: MaxRasterDPI=600

Note: 96 DPI is an efficient setting to use if your primary usage is to only view images at 100% zoom level and do not print them since many monitors have 96 DPI resolution (or calculate your video card's pixel width / monitor's visible width in inches = your monitor dpi resolution). If you set a lower resolution (such as 96 DPI) and then use the viewer to print a file containing raster images to a printer that has 600 DPI resolution, the image will view fine on the monitor but will have reduced fidelity on the printer due to the printer having greater resolution than the published image.

EmbedTrueTypeFonts   	This setting tells the application whether to embed true type fonts during conversion.
TRUE	=	(Default) True type fonts are embedded
FALSE	=	True type fonts are not embedded

ForceEmbedTrueTypeFonts   This setting tells the application whether to force true type fonts to be embedded. If set to True, all true type fonts are embedded regardless if there is an exact match on the system doing the converting. The closest match to the font requested is used if an exact match is not found. To use this flag, the EmbedTrueTypeFonts setting must be set to TRUE
TRUE	=	(Default) All true type fonts are force embedded 
FALSE	=	True type fonts are not force embedded

[DWG2DL]	
The [DWG2DL] section sets driver configuration parameters for conversion of DWG and DXF files to CDL format.
ShxPath	Specifies the path for the loader to search for font files. A semicolon is used as the path separator. 
	Format is ShxPath=path1;path2
XrefPath	Specifies the path for the loader to search for the cross-referenced files. A semicolon is used as the path separator. 
	Format is XrefPath=path1;path2
	Example:
	ShxPath=C:\Program Files\AutoCad 2004\Support;C:\Program Files\AutoCad 2004\Fonts;XrefPath=C:\ACAD\xref
PageLoadOrder          Tells the loader the order of page layouts.
                                                          0: Paperspace first
                                                          1: Modelspace first
                                                          2: Paperspace only
                                                          3: Modelspace only
			          4: Similar to 0 except the last active layout is first
	
                                                          If only one page exists, it is loaded.
 
Example:
ShxPath=C:\Program Files\AutoCAD 2004\Support;C:\Program Files\AutoCAD 2004\Fonts;; 
XrefPath=c:\ACAD\xref;.\models;.\blocks;
PageLoadOrder=0

Dohybrid	Tells the loader to load hybrid files from the same directory with the same file name. 
	TRUE (default) 	= 	Load hybrid files from the same directory with the same file name.
	FALSE		=	 Do not load hybrid files.

HybridExtensions	Tells the loader that if a file exists with the same base name as the AutoCAD file and has one of the following extensions, to load the file as a raster reference.
HybridExtensions=cg4;rnl;g4;mil;gp4;cal;tif;

XrefNameAsFileName	Tells the loader to use the Xref block name as the file name if the file is not found using the Xref path.  This setting should only be (and needs to be) changed to true if you are using a Brava!/Webtop integration and you are using Cadlink to import Xrefs. 
Format is XrefNameAsFileName=false

UseLineWeights	Tells the loader whether to use line weights or line thickness for printing.
	TRUE (default) 	= 	Use lineweights if available for printing.
	FALSE		=	 Use line thickness shown on display for printing.

[CGM2DL]	
The [CGM2DL] section sets driver configuration parameters for conversion of CGM files to CDL format.

CCR	Specifies whether to do color collision recognition. 
TRUE (default)     = 	Do color collision recognition.
	FALSE		=	Do not do color collision recognition.

ParseForExtents 	Specifies whether to parse the file for extents or use defined page size.

TRUE 	= 	 Use the extents of all entities in the file.
	FALSE (default)	   =	 Use the page size defined in the file.
