ODB++ to Gerber Revision History

This page contains the summary of odb2gbr release dates, versions and changes/fixes made for that release.

Version 1.95    January 30,2012

Fixed bug in reading ODB++ with GZ files.

Added a -nocopyin option to open the input ODB++ directory as-is. The input directory and sub-folders must be writable. It must be noted that when using this option, the input ODB++ directory will be modified directly by the program.

Version 1.94    December 6,2011

This version resolves issue #188 (Symbol Error) where a symbol is drawn as a moire with invalid parameters. This is caused by a bug in reading custom symbols that begin with a number.

Gzip compressed features are now supported.

Speed improvement (up to 20x) on ODB++ input with complicated surfaces.

Version 1.93    October 17,2011

This version resolves a few issues reported by different clients.

Version 1.92    August 11,2011

This version resolves issue #184 (274x Error) in which the children steps are translated in the wrong order. This is caused by a bug when combining children steps.

Version 1.90    June 3,2011

This version resolves font shx conversion issues (updated ODBFNT2SHX.DLL) as well as untar issues.
It also contains the updates from v1.89 (new ODB2GDS and ODB2OAS conversion capabilities in odb2gdx.dll and odb2gbr_cmdlne.exe).

Version 1.88    February 8,2011

Fixed issue #180 (Dynamic Text Orientation) where some of the orientation codes in the DAT output file is incorrect. This is caused by a bug in calculating the orient code of mirrored texts.

Fixed issue #181 (Error sample) where ACS_createODBOutputDynTxt fails with option1 and ACS_getODBLastErr returns "memory access error" or "null". This is caused by a bug in the library definition and in setting the error codes.

Created a new function ACS_convertODBAttr that converts the coordinates of a given ODB++ step/layer/attributes combination without GERBER convertion.

Version 1.86    January 7,2011

Added the functionality requested as issue #171 (Dynamic Text Orientation) where: the final orientation is written in the "Emitted Text/Attribute" section of the DAT and PLT output files.

Fixed issue #172 (Missing ADandMO in 274X) where: the 274x header is not in the GERBER output. This issue is caused by adding the 274x header information into the wrong GERBER output when the output directory is different in the calls to ACS_createODBOutputPlot, ACS_createODBOutputAttr and ACS_convertODBInput.

Added the functionality requested as issue #173 (Plotstamp output in 274x) where: features that has the attribute ".orbotech_plot_stamp" is omitted from the GERBER output if "-plotout" option is specified on conversion or on the call to ACS_createODBOutputPlot function.

Added the functionality requested as issue #174 (Surface coordinate) where: the surface feature's center coordinate is used in the ATR output file.

Added the functionality requested as issue #175 (Arc coordinate) where: the arc feature's center coordinate is used in the ATR output file.

Added the functionality requested as issue #176 (Line coordinate) where: the line feature's start point coordinate is used in the ATR output file.

Fixed issue #178 (274x header repetition) where: the GERBER output's header information is repeated several times. This is the same bug that caused issue #178.

Added the functionality requested as issue #179 (Dynamic Text Polarity) where: the final polarity is written in the "Emitted Text/Attribute" section of the DAT and PLT output files.

Version 1.85    Dec 21,2010

Created a new function to create a DAT (dynamic text) file without creating a GBR file (option 1): ACS_createODBOutputDynTxt

Fixed issue #169 (Attribute Error) where: attributes without values are not output into the ATR file.

Fixed issue #170 (Attribute Error) where: a rectangle without an attribute is not output into the GERBER file when cvtnonzero is set to false.

Fixed issue #172 (Missing ADandMO in 274X) where: the 274 header is not in the GERBER output.

Version 1.83    Dec 15,2010

The option to exclude nonzero pad is implemented.

Version 1.82    Dec 12,2010

Created two new functions to create a PLT or ATR file:
ACS_createODBOutputPlot and ACS_createODBOutputAttr

Added two new arguments to create a PLT or ATR file from the dialog or the function ACS_convertODBInput:
-attrout:attrname,0|1 and -plotout

The usage of the two new functions and the two new arguments can be found in the acs_odb.h header file provided in the package.

Version 1.80    Sep 9,2010

This release resolves issue #166 (Pattern Shift) where ODB2GBR's Gerber output is shifted up and is intersecting with other data.

Version 1.79    July 19,2010

This release resolves issue #164 (Dynamic Text) where ODB2GBR's dynamic text $$WEEK-DAY is not output in the dynamic info file (DAT).

Version 1.78    May 17,2010

This release resolves issue #159 (Pad NG) where ODB2GBR's output was missing a scratch data.

Version 1.77    April 22,2010

This release resolves issue #157 (Pad NG) where ODB2GBR's output draws a line with round dcode 0.001inch instead of 0.000 width.

Version 1.76    April 7,2010

This release resolves issue #154 (Read Error) where ODB2GBR fails to open a ODB++ files containing directories with windows reserved names. This was fixed.

This release resolves issue #156 (Log Dynamic Text) where ODB2GBR outputs dynamic text into the GERBER output even with the "log dynamic text info" option checked. ODB2GBR will no longer output dynamic texts into the GERBER output if the "log dynamic text info" option is checked.

Version 1.75    March 30,2010

Issue #153 was fixed.

The crash was related to the new dynamic text feature for a special case of Genesis emulation. This was fixed.

Version 1.74    March 27,2010

First release of the ODB++2GBR with Dynamic text support.

Version 1.73    March 4,2010

First release of the ODB++2GBR with 64 bit support.

The option "-nolog" to disable logging is added. This option should be passed into the ACS_openODB function. In the GUI, it should be specified in the Input Settings' Arguments.

The DLL has been changed. OEM users should now use the odb2gdx.dll instead of the odb2gbr.dll that is provided in the package.

The headers acs_odb.h and acs_odb_structs.h have been changed. for OEM, please use the latest headers included in the package when compiling your own program. Also, please make sure that you use the error code variables defined in the acs_odb_structs.h header file since the values change when a new error code is added.

Version 1.72    January 7,2010

This release includes better integration to Netex-G.

Version 1.71    November 24, 2009

This release includes an interface to Netex-G. ODB++2GBR users will now be able to generate the Netex-G job file along with the Gerber data for the metal, drill and component layers. The job file will also include the net information.

Version 1.70    September 29, 2009

This release resolves issue #146 (Hungup) where ODB2GBR hangs when opening the ODB++ file 95827-00.tgz on a Windows 2000 Advanced Server platform.

The issue is caused by spawning too many threads when decompressing .Z files. ODB2GBR hangs while waiting for all of the threads to finish.

This issue was solved by decompressing .Z files sequentially instead of concurrently.

Version 1.69    September 22, 2009

This release resolves issue #145 (AM Error) where: The macro (AM) definition does not exist for a declared aperture (%ADD28Symbol_laser_nai_mark_a*%).
AM Error can be found in ODB++ files that potentially produce large numbers of apertures (greater than 9999). In order to minimize the number of aperture definitions, ODB2GBR sorts and remaps all unique apertures in its internal database. As a result of this remapping process, the macro in question was incorrectly tagged as 'being used'. Since it was tagged, it was not discarded at cleanup of unused apertures.
This macro appeared definition actually appeared and was used in the feature file for the layer in question. However, because it contained scratch data, it had to be exploded and therefore does not appear explicitly in the Gerber output.

This issue was solved by tagging apertures as 'being used' as they are output.

Version 1.68    September 1, 2009

This release resolves the file opening issue reported by Samsung.

Version 1.67    August 31, 2009

This release resolves issue 142 from Hitachi where ODB2GBR failed to open a valid ODB++ tar file.
The problem was related to the fact that originally the TAR format did not support long path names. The TAR specification now supports long path names with two different mechanisms. ODB2GBR was upgraded to support that as well.

Version 1.66    June 21, 2009

This release resolves two dynamic texts issues raised by Samsung:

Dynamic text $${JOB} is not translated but appears literally in the output.

Dynamic text $$JOB is translated with a different job name than the job name specified inside ODB++ job/misc/info file, even though ODB2GBR v1.65's translation of $$JOB agrees with the Valor Viewer v7.3.2.0.

Version 1.65    June 18, 2009

This release resolves issue #138 (Data lost) where some of the ODB++ data were lost in conversion from ODB to GERBER.
This issue was caused by confusion of a step and a symbol with the same name.

This release resolves issue #139 (Data lost) where the date dynamic text was not converted to the real-time date during conversion.
This issue was caused by ODB2GBR’s inability to recognize a dynamic text string. $$Date-mmddyyyy was not recognized when checking for dynamic text because of the lower case ‘mmddyyyy’.
In general, all dynamic text recognition was case insensitive, however, this was a special case where the string following $$Date- was not handled properly.

Version 1.64    June 18, 2009

This release resolves issue #135 (Coordinate Error) where the ODB2GBR's output surface has a different width than in valor.

NOTE:

To enable this precision use the argument -format:2.7
To avoid overflow use -format:2.7 for Inch and -format:3.6 for MM as the maximum.

Version 1.63    June 18, 2009

This release adds the control to output the SR command even if BreakSR is yes.
If this mode is selected, the other commands are not output (IR, MI etc.).

USAGE:

1. In the GUI:
In the G2K Emulator Dialog set BreakSR to Yes and check the Step and Repeat checkbox.

2. In the command line:
Pass both arguments "-step_repeat" and "-g2k_break_sr:1"

3. In the function ACS_convertODBInput():
Pass both arguments "-step_repeat" and "-g2k_break_sr:1" into the list of additional arguments (argv)

Version 1.62    June 2, 2009

This release resolves issue #136 (Without extension) where the output gerber file was missing header information..

Version 1.61    May 18, 2009

The command line argument -format: has been provided to control the Gerber output Format.
The default has been 2.6 for Inch output and 3.5 for MM output.
We suggest that 2.7 format for Inch and 3.6 format for MM are safest maximum to use without generating overflow values..

Version 1.60    April 21, 2009

This release resolves issues 132 and 133 (Step-Repeat Error) where incorrect SR information was generated into a Gerber output.

Version 1.59    March 2, 2009

This release resolves issue #129 (Memory Error) in which some allocated memory was not being freed.

This release fixes the View Gerber option in ODB2GBR.

Version 1.58    Febraury 20, 2009

This release resolves issue #129 (Memory Error) where some allocated memory was not being freed.

Several new functions to free memory can be found in the header file acs_odb.h which is included in the package.
Because of the new functions, the library (odb2gbr.lib) has been changed. This means that you have to recompile any program that uses odb2gbr.dll.
To compile, please use the latest odb2gbr.lib and acs_odb.h which can be found in the "lib" directory of the ODB2GBR's installation directory

An error occurs when the "ODB Input file path" is set to "IP address" or "Network Computer name".

Version 1.33    April 22, 2008

This release resolves the Dynamic Text Error where:
- Some of the Dynamic Texts are converted incorrectly..

A function to get the out_x_scale and out_y_scale value of a given Step/Layer combination:
int ACS_getODBOutScale(char * stepName, char * layerName, double * x, double * y);
- This function gets the out_x_scale and out_y_scale value of the specified step/layer combination.
- This function returns 0 if successful and 1 if failed
- x will be set to layer's out_x_scale value
- y will be set to layer's out_y_scale value

int ACS_getODBTopStepListName(char *** topStepList, int * numTopStepList);
- This function gets the list of the step names with no parents (top steps)
- This function returns 0 if successful and 1 if failed
- topStepList will be set to the list of the top step names
- numTopStepList will be set to the number of top steps

int ACS_getODBTopStepListIndex(int ** topStepList, int * numTopStepList);
- This function gets the list of the step indices with no parents (top steps)
- This function returns 0 if successful and 1 if failed
- topStepList will be set to the list of the top step indices
- numTopStepList will be set to the number of top steps

char * ACS_getODBMostLikelyTopStepName();
- This function returns the top step name or NULL if it failed

int ACS_getODBMostLikelyTopStepIndex();

The index returned by ACS_getODBTopStepListIndex and ACS_getODBMostLikelyTopStepIndex is used for the Step List returned by the function ACS_getODBStepInfoList

Example:

struct ODB_StepInfo *stepList;
int stepCount;
int ret;
int idx;
ret = ACS_getODBStepInfoList(&stepList, &stepCount);
if(!ret){
idx = ACS_getODBMostLikelyTopStepIndex();
if(idx != -1)
printf("Most Likely Top Step: %s\n", stepList[idx].Name);
}

The fields of "struct ODB_StepInfo" can be found in the header file acs_odb_structs.h, which is included in the package.
NOTE:
- The declaration of these new functions can be found in the header file acs_odb.h which is included in the package.

- Some GENESIS Gerber output does not match the ODB2GBR output because of out_x_scale and out_y_scale values..

Version 1.25    January 8, 2008

This release resolves the Dropped User-Defined Symbol Error where:
- Recursive use of user defined symbols are not supported. It is now supported.

Version 1.24    December 13, 2007

Version 1.23    November 30, 2007

This release resolves the File Open Error where:
- An ODB File was not successfully opened.

Version 1.21    September 19, 2007

This release resolves the Layer Count Issue, Line Error, Dynamic Text Error and File Open Error where:
- There is an excessive number of layers in the output.
- The order of layer conversion is incorrect.
- Some dynamic text are converted incorrectly.
- An ODB File was not successfully opened.

Version 1.19    September 10, 2007

This release resolves the Layer Count Issue where:
- Too many Gerber layers are created. It was improved to create less layers. The number of layers for the file test.tgz was reduced from 66 to 15.

This release resolves the File Open Error where:
- The program detects irregular files (files that are not in the ODB++ spec) and an error is returned. This had to do with .org files that are not defined in the ODB++ specifications. The file in question was a font file called standard.org.
In the fix for the open error, this font file is treated as any other font files, namely...
(1) Font files are read and if not recognized as a font file, the file is ignored (not converted into an SHX file).
(2) Feature files are converted into GDX. There are text lines in the feature files that make use of SHX files. If the text lines make use of a non-existing SHX file, an error is returned.

This release resolves the Polygon Data Issue where:
- The default polygon output is butting edge. The default polygon output is now cutline. New command line option -butting is now available. Use this option if you need a multiple polygon output instead of a single polygon (Issue 61).

Version 1.18    August 16, 2007

This release resolves the Polygon Data Issue where:
- The default polygon output is butting edge.
The default polygon output is now the same as v1.16 (single polygon). To enable multiple polygon output, the optional argument for ACS_convertODBInput is "-butting".
Please see the acs_odb.h header file included in the package for more information.

Version 1.17    August 9, 2007

This release resolves the Polygon Data Issue where:
- The only possible type of polygon conversion is cutline.
Surface conversion has been modified to enable 2 types of polygon output. The default output is butting edge (2 or more polygons) and the alternative output is cutline (single polygon). Cutline output can be enabled by passing "-cutline" in the argument list of ACS_convertODBInput. Please see the acs_odb.h file included in the package for more information.

This release resolves the Dynamic Text Error where:
- Some dynamic text are converted incorrectly.

Version 1.12    July 24, 2007

This release resolves the Text Error where:
- Some text are converted incorrectly.

Version 1.11    July 18, 2007

Version 1.10    July 16, 2007

This release resolves the Text Position Error where:
- Some text initial position does not match the text created by Genesis.

This release resolves the Pad placement Error where:
- Some pad transformations are incorrect.

Version 1.09    July 12, 2007

This release resolves the Text Position Error where:
- Some text initial position does not match the text created by Genesis.

Version 1.08    July 9, 2007

This release resolves the Text Position Error where:
- Some text initial position does not match the text created by Genesis.

Version 1.07    June 29, 2007

This release resolves the File Open Error where:
- An ODB File was not successfully opened because of a SR memory allocation bug

three new API calls have been added to help a calling program determine the revision of the DLL

char * ACS_getODBVersion();
char * ACS_getODBRcs();
char * ACS_getODBDate();

See the acs_odb.h for details.

Version 1.06    June19, 2007

This release resolves the Text Position Error where:
- Some text placement does not match the text created by Genesis.

Version 1.05    June9, 2007

This release resolves the Surface Error where: - Some polygons are converted incorrectly.
This issue was fixed by collecting groups of islands and holes. The current group of holes are subtracted from the previous group of islands.

Version 1.04    June7, 2007

This release resolves the Data Origin Error where:
- Some Data placement are converted incorrectly.

This release resolves the Surface Error where:
- Some polygons are missing holes.
This issue was fixed by collecting all the islands and all the holes in the surface and subtracting all the holes from the islands all at once.

This release resolves the Square Line Error where:
- Diagonal Square Lines are converted incorrectly.
Please note that our previous output was how Gerber files interpret diagonal lines drawn with a square. To draw the same output as Valor, we turned the diagonal lines into polygon area fills (i.e. using G36,G37 Gerber G codes).

Version 1.03    May 31, 2007

This release resolves the Text Position Error where:
- Some text placement does not match the text created by Genesis.

This release resolves the Application Error where:
- A real-time problem caused the program to access freed memory.

Version 1.02    April 03, 2007

This release resolves the Font Error where:
- Some text are converted with an incorrect font.

This release resolves the Step and Repeat Error where:
- Some SR data are converted incorrectly.

This release resolves the Gerber Outline Error where:
- The Gerber outline primitive draw is incorrect.
The Gerber outline primitive output has been fixed to follow the convention. CAM350 should now load and draw the Gerber file as expected.

Version Alpha 4    April 03, 2007
