TIFF2MEBES Revision History

Rev 1.44 07-15-2009

This version now supports RGB, Indexed Color, and Greyscale TIFF including LZW and no compression. In addition, the -union command line option creates more optimal (merges most touching scan lines into a single boundary) GDSII output.

Tiff2mebes can now export Gerber RS274X output.

Selected options and input/output directories are saved into the registry.

Input and output file can now be viewed.

Rev 1.34 Windows 10-23-2008

The Dialog has been fixed. It can now accept BMP files that starts with 'BM'. The file selection can also filter BMP files now. The engine did not change. It is still v1.33

Rev 1.34 Solaris/Linux 07-17-2008

We upgraded our software to support Tiff compression version 5.

Rev 1.33 Windows 07-1-2008

Our TIFF and BMP reader now supports a black and white image that is defined in a color file.

Rev 1.31 Windows 05-16-2008

A pervasive coding error that could potentially lead to out of program data space errors (access violations) was fixed. This manifests itself in the new output as padding in MEBES contain "0"s, not garbage

Previously data could cross stripe boundaries - now data that crosses a stripe boundary is broken up into the necessary number of pieces and appears in the correct stripe definition.

Tiff2mebes is now reporting data loss, which caused due to insufficient memory.

Data loss due to file size limitations of MEBES IV now detected and reported - before it was not reported. now the user is prompted to use a larger grid or MEBES V.

Open or nested stripes are now not created - previously they were created.

Empty segments, ie. segments that contain no drawable data are not created, entries for those segments in the segment directory now have the offset "0". Empty segments are illegal in MEBES IV and V..

Tiff2mebes now supports USB licensing

The date code format is now correct for MEBES V.

Rev 1.30 Windows 05-12-2008

Tiff2mebes generated the wrong polarity unexpectedly. This has been fixed.

Rev 1.20a Linux 09-20-2007

Tiff2mebes was crashing when libcxa.so.3 was missing. This had been fixed.

Rev 1.20 Linux 03-30-2007

Tiff2mebes created a bad MEBES output on Linux. This had been fixed.

Rev 1.17 Windows 05-31-2005

Fixed a problem reported by Kovio in the Tiff2Tiff conversion when scaling down a file from 25400DPI to 3175.

Rev 1.05 03-23-03

More than 4 Gigabytes GDS/MEBES output supported.

In tiff2mebes v1.03/v1.04 (Unix/Windows), when the pixel height specified is larger than stripe height, the MEBES output wouldn't be correct. This has been fixed.

In tiff2mebes v1.03/v1.04(Unix/Windows), GDS output had rounding problems causing GDS output to be truncated. This has been fixed. For MEBES, different grid can be specified. User should take care that the grid and pixel size should be specified in such a way that "(Dimension in pixel * pixel size / grid )" is a round number, to avoid rounding problems. .

Rev 1.04 12-16-02

Error messages are more descriptive and explaining what is wrong with the source file.

Rev 1.03a 09-11-02

A new install script is now part of the release (prior, the program had to be installed manually) as well as support for flexlm licensing.

We've added support for TIFF files that are internally broken into strips. For large TIFF files this is not uncommon.

Rev 1.01 08-20-02

Error messages in case the tiff file format is not supported.

Image Size in pixels and microns is being displyed in the menu after the file is selected.

Rev 1.00 08-15-02

Initial release today on Windows. This program is shipped with the Flexlm license manager.
