5. 7 4 5 Cell Array to Raster Conversion Some drawing packages do not support all possible types of cell arrays The CGM Converter can convert cell arrays to raster files Cell arrays can be joined if needed Some CGM packages generate cell arrays that are one unit high or wide a typical trick to put seismic data in a standard CGM file The default raster type used is TIFF but you can also generate Windows BMP or JPEG files 7 4 6 Force VDC Abstract You can ditect CGM Converter to convert a metric CGM to an abstract CGM 7 4 7 Real to 16 bit Integer Conversion By default real VDC are converted to normalised integer 16 bit co ordinates This is done because some drawing packages such as MicroStation do not support real numbers 65 CGM CONVERTER You may want to disable this option 7 4 8 Mode Absolute Line widths edge widths and markers can have sizes that are either scaled or absolute sized This can cause problems for certain drawing packages such as Corel DRAW that do not support scaled modes correctly CGM Converter can enforce that only absolute modes are used within the CGM 7 5 CGM Converter Limitations CGM Converter is currently only able to convert CGM version 1 CGM and CGM PIP 1 files Conversion is only done on the first CGM picture Fill joining is not performed on polygon sets These are in principle never joined If they are it is an example of how inefficiently certain packages create CGMs The
