.Net Core 2.2 issues


#1

Hi Aspose. I’m building a web application using your library and i faced some issues. First of all i’m using .Net core version 2.2 inside linux Docker container. First issue is related to the fonts: i can’t make my application use correct fonts. I already added fonts in the local directory and added reference to it with FontsLoader.LoadExternalFonts() and this doesn’t help.
Second issue is related to the fact, that in some cases when i’m trying to get thumbnail of an arrow, the result thumbnail doesn’t contains an arrow. This is a known issue and it was resolved here but this issue still reproduced win .net core in linux.
The third issue is that in some cases background color of shapes differs from the original one in the Powerpoint. You can see the difference here and lines in thumbnails have slightly more width and are not rounded.
And the last issue is related to the fact, that Linux doesn’t support .wmf/.emf files. So if presentation contains embedded .emf/.wmf files i can’t get their thumbnail.

@obrusentsov,

I have observed your issues and requirements.

I have observed your requirement and we need to have source project and source file along with used fonts that are not getting loaded.

I request you to please share the source file, sample project and output achieved on your end.

I request you to please share the source file, sample project and output achieved on your end.

Your observation is right in this regard.

I also suggest you to please first try using latest Aspose.Slides for .NET 19.10 on your end so that we may proceed further with investigation on our end.

Thank you for your fast reply. Here is a link to a source code of a sample with a bad font. And here you can see how Powerpoint is rendering it

Hi guys. Is there any information concerning .Net core available?

@obrusentsov,

I have worked with source files shared by you using Aspose.Slides for .NET 19.10 and unable to observe issue. I like to inform that i have tested this on window 10 environment. Can you please share complete environment details with us. For reference i have attached my generated result with you.slide1.png (44.5 KB)
