All object colours occurring in the PDF document are transferred to the document colour list of the new Calamus document. For the various colours the following applies:
| Gray | pdf_gg_Gray, gg = 0x00..0xFF Internal representation as gray value. |
| RGB | pdf_rrggbb_RGB, xx = 0x00..0xFF Internal representation as RGB. |
| Calibrated gray and RGB | It is not converted! Represented as gray and RGB! |
| CMYK | pdf_ccmmyykk_CMYK, xx = 0x00..0xFF Internal representation as CMYK. |
| Lab | pdf_rrggbb_RGB(Lab), xx = 0x00..0xFF Internal representation as RGB, Conversion Lab -> XYZ -> RGB_709. |
| Indexed | pdf_name_index_INDX, name = Internal Name Internal representation by the corresponding colour from the table. |
| DeviceN | pdf_......(DevN) Internal representation by an alternative colour area. Depends upon the number of the components gray, RGB, CMYK with the auxiliary (DevN). |
| ICCBased | pdf_......(ICC) Internal representation by an alternative colour area. Depends upon the number of the components gray, RGB, CMYK with the auxiliary (DevN). |
| Pattern | pdf_name_PATT, name = Internal Name Internal representation as RGB black. The colour area pattern is not representable. If there are objects from several colour pattern areas, they are differentiated by their internal names. |
| Separation | pdf_xx_plane, xx = 0x00..0xFF, plane = Name of the decoration colour If a decoration colour appears in the PDF document, it is first examined to acsertain if there is a colour of same name as the existing decoration colour (in the document). If a name match is found, that colour is used, irrespective of whether the internal colour representation in the PDF and CDK documents agree. If the decoration colour is a standardized colour (HKS. , FOCOLTONE. , RAL ), then the appropriate modules are searched (if necessary with automatic reloading!). If the colour is found, it is copied. Again, recognition is only based on the name - there is no examination of colour equality! Otherwise a new decoration colour is created from the data in the PDF document. The specialdecoration colour Noneis represented as transparent, and the decoration colour Allas black, if the alternative colour area CMYK is other than white! Hint: If, after the import, black surfaces seem to cover something, you should check whether, in the document colour list, the colour designation pdf_alloccurs. If so, change black to white. |
