Manifold and cartography – output formats & loading to presentation tools issues

I have noticed a number of threads in this form on using Manifold for cartography (the pretty end of the output spectrum, I guess!) Consensus seems to be that the best results can be obtained by using Manifold for the GIS bits and exporting a layout to Adobe Illustrator for final presentation formatting & output/printing. I am essentially looking to produce a document containing several maps from Manifold. I need to change Manifold’s RGB colours to CMYK and also add comments, additional formatting etc. hence the need to put the Manifold output into another document form. I have tried producing outputs from Manifold layers in emfGDI+, pdf and AI formats and tried opening them with Corel Draw Graphics Suite X3 (the latest version) and Adobe Illustrator CS2 (latest version 12.0.0). I am also considering Adobe InDesign CS2 as the document will be quite large (120 pages, with about 90pages being maps). However all is not going smoothly!!! 1. In CorelDraw I can import a pdf file exported from Manifold 6.5 but I cannot import the same pdf file as output by Manifold 7x (7.1.1.279). Corel just hangs after specifying the pdf file and never reaches the next dialog step (font substitution). This does not happen for all pdf files – I produce 5 pdf’s from the same layout, just with different scopes – some can be imported, others hang CorelDraw ??? Has the pdf exporter changed from Manifold 6.5 to 7x ?? I am using document.NewExport('PDF') from a script, exporting text as text (not vector). 2. I have noticed that Corel Draw cannot import the .ai files as output by Manifold although it has a filter for them (AI files). Is there a compatibility issue with the AI filter used in Manifold? 3. When I view (in Adobe Reader) a pdf file output by Manifold , it comes out clearly and with all the layers separate. On input to Corel, layers are lost, all objects are converted to curves and I end up with 2000 objects all at the same level. I have also noted that some objects on some pdf’s are distorted (e.g. I have a land area surrounded by sea and I overlay a number of Themes over the land mass in Manifold – in Corel, the land mass seems to have extra or missing points so that the fill extends over some of the sea area. Reading the same map layout output as an emf does not produce this problem in Corel, but I would like to retain the layers in pdf, if possible. 5. Opening the .ai file in Adobe Illustrator retains the layers, but there are a number of points outside the frame of the original layout. i.e. the .ai output hasn’t been fully cropped to the layout scope in Manifold. Any comments or suggestions from anyone who has successfully taken Manifold output into Adobe Illustrator or CorelDraw (or other such software) would be much appreciated. You said: '2. I have noticed that Corel Draw cannot import the .ai files as output by Manifold although it has a filter for them (AI files). Is there a compatibility issue with the AI filter used in Manifold?' I what to report you that I use Manifold 7x (7.1.1.279) and CorelDRAW 12 and when I export my outputs of maps in AI format I can open its in Corel with no problems. I guess it would be best to take these problems to Corel or Adobe, since their developers are in better position to look what is going on during the import. It can certainly be that the output generated by our export code is malformed, but our tests do not show that and this makes it hard to debug the problem from our end. Opening the .ai file in Adobe Illustrator retains the layers, but there are a number of points outside the frame of the original layout. i.e. the .ai output hasn’t been fully cropped to the layout scope in Manifold. This is strange. This might be similar to the above, ie, a problem at Adobe's end, but since you are using the latest version of Illustrator, I will ask: are there any error messages when you open the PDF or AI in Illustrator? When I export Manifold layouts and open them with Illustrator, I've also noticed the fifth point you mentioned (areas and lines extending outside the layout frame). I was usually able to fix it by saving the layout twice: 1. the map without the border/graticule labels, legend, and scale bar and 2. the border, legend, and scale bar without the map. Then in Illustrator you can take those two files and put the original map/layout back together. If that doesn't work, you could try clipping masks or clipping to the artboard options within Illustrator, though they're not elegant alternatives. Source.
