Painting Command not supported on webcgm files

[andrlange]

I have tried to read CGM Files from our vendors but they are not decoding correctly.

"ProfileId:WebCGM","ProfileEd:2.0","Source:Created by IsoDraw 7.3"

Painting command: Unsupported - BeginApplicationStructure [applicationStructureIdentifier='IsoL1', applicationStructureType='layer', inheritanceFlag=false] id:21
2024-09-17T08:44:11.507+02:00 INFO 75936 --- [frontend] [nio-8080-exec-9] de.tddsgmbh.frontend.utils.CGM4SVG : Painting command: Unsupported - ApplicationStructureAttribute [applicationStructureAttributeType='layername', sdr=StructuredDataRecord [members=[[type=SF, count=1, data=[Standardebene]]]]] id:1

You will find the list of supported commands here: jcgm features.
Note 1: an unsupported command will not prevent the interpretation of the other supported commands. The image will still be rendered by the library.
Note 2: this command is typically used for the "interaction layer" mentioned in my reply here.

Using the result and render this as svg jcgmtosvg shows just an empty image. I can send you the cmg on demand.

Sure @andrlange, would appreciate to have the CGM sample for troubleshooting.

@daviddiana11 you can download the example cgm files via: https://downloads.cfapps.cool/downloads/cgm.zip

Thanks @andrlange. I had a quick look:

1. CGM processing
   The "isoview.cgm" could be rendered as CGM. It contains a JPEG image plus some overlay.
   The "allprims.cgm" could not be rendered. Either the CGM is corrupted - to be checked if it can rendered by another CGM viewer - or a fix is indeed required.

2. SVG conversion
   The "isoview.cgm" remains blank once converted to SVG because the converter does not support embedded raster images yet ("Tile" commands),

[andrlange]

Are there any plans to extend the features so that rastered and embedded images will work? I could even provide more examples... allprims.cgm is readable with webviewers, it is almost text.
