Hello,

I’m generating a document and want to save it as a pdf. Locally this works fine but when running from a server I get the following error:

TextFormat has no associated Font, and a default font could not be found. To avoid this situation, assign an available font to FontCollection.SystemFonts.DefaultFont if it is null.

I asume the server doesn’t have access to certain fonts so I followed what the error recomends by doing the following:

_fontCollection = new FontCollection {DefaultFont = StandardFonts.Times}; _fontCollection.RegisterDirectory("./Fonts"); var font = _fontCollection.FindFamilyName("CorpoS"); if (font != null) { _fontCollection.DefaultFont = font; } _logger.LogInformation($"Default font: {(_fontCollection.DefaultFont != null ? _fontCollection.DefaultFont.FontFamilyName : "not found.")} - Font count: {_fontCollection?.Count}"); doc.SaveAsPdf(memoryStreamPdf, _fontCollection);

I still get the same error but my logging logs the following:

Default font: CorpoS - Font count: 4

So what am I doing wrong here?

Hi Martin,

We are sorry for the delayed response on this. We were trying to replicate the issue at our end using the provided code snippet by you assuming you are working with the Grapecity Documents for Word and generating the PDF file.

Here, we observed that there is not FontCollection class available.

Hence, could you please share a small demo sample depicting your issue. So that we can replicate the issue at our end and assist you accordingly.

Regards,

Manish Gupta

Hello Manish,

Yes I’m using GrapeCity.Documents.Word and GrapeCity.Documents.Layout both version 3.0.0.42 to generate my documents.

Please be advised that the issue doesn’t arise running localy. It first apears once I have deployed on our test server. Is it posible that the issue arises from not having a license key on the test server?

Below is a short example of what I do (I hope I got the structure right)):



	FontCollection _fontCollection = new FontCollection {DefaultFont = StandardFonts.Times};

	_fontCollection.RegisterDirectory("./Fonts");

        var font = _fontCollection.FindFamilyName("CorpoS");
        if (font != null)
        {
            _fontCollection.DefaultFont = font;
        }

	GcWordDocument doc = new GcWordDocument(_settings.GrapeCityKey);
	doc.Load(memoryStream); //memoryStream contains a docx templpate.

        var runs = doc.Body.Runs;
        List<PersistentRange> runRanges = new List<PersistentRange>(runs.Count);
        foreach (var run in runs)
        {
            runRanges.Add(run.GetPersistentRange());
        }
	
	foreach (var rr in runRanges)
	{
		//do a regex match
		if(match)
		{
			var font = rr.ParentRun.Font;
			rr.Clear();
			var r = rr.Runs.Last;
			
			foreach (Match m in matches)
			{
				r.GetRange().Runs.Insert(value, InsertLocation.After);
            			r = SetFont(r, font); //Sets the font on the range above.
			}

			rr.Runs.First.Delete();
		}
	}

	var ms = new MemoryStream();
        doc.Save(ms, DocumentType.Document); //Word document is saved fine.

	var msPdf = new MemoryStream();

	//Error occurs on line below. Doesn't matter wich one I use.
	doc.SaveAsPdf(msPdf, _fontCollection); //doc.SaveAsPdf(msPdf);

Hi Martin,

Please replace the code at the top of your fragment with this:



FontCollection.SystemFonts.DefaultFont = StandardFonts.Times;
FontCollection fontCollection = new FontCollection();
fontCollection.RegisterDirectory("./Fonts");
var font = fontCollection.FindFamilyName("CorpoS");
if (font != null)
{
    FontCollection.SystemFonts.DefaultFont = font;
}

Let me know if this helps.

Thanks,

Dmitry.

Hi Martin,

It’s time make active reports grate again.

I builded docker image for reproduce this bug https://hub.docker.com/repository/docker/vahpetr/webdesigner-mvc-core

docker pull vahpetr/webdesigner-mvc-core:1.0.0

And created docker-compose for you.

version: "3.9" services: reports: image: vahpetr/webdesigner-mvc-core:1.0.0 restart: always volumes: - reports_resources:/app/resources - reports_datasets:/app/datasets - reports_templates:/app/templates ports: - 80:80 - 443:443 volumes: reports_resources: driver: local reports_datasets: driver: local reports_templates: driver: local

Reproduce:

1/ Create docker-compose.yml file

2/ docker-compose up -d

3/ open localhost:80

4/ open any report, Tablix.rdlx for example

5/ run preview

Result:

Failed rendering document.

TextFormat has no associated Font, and a default font could not be found. To avoid this situation, assign an available font to FontCollection.SystemFonts.DefaultFont if it is null.

Expectation:

No error. Correct preview.

I think problem in miss default fonts in container. Please add correct handling this error.

P.S The container is created automatically by the dotnet tool tye https://github.com/dotnet/tye

Hi Petr,

If I understand the issue correctly, in your server environment GcPdf could not find any system fonts, in this case you need to provide the fonts explicitly to GcPdf, several samples in our demo site show how to do it, e.g.:

https://www.grapecity.com/documents-api-pdf/demos/features/fonts/font-collection/code-cs

https://www.grapecity.com/documents-api-pdf/demos/features/fonts/surrogates-port/code-cs

Hope this helps,

Dmitry.

Hi Petr,

Having re-read the thread I think the problem is that you’re using Docker, so your fonts must reside inside the dockerfile. When running on Linux, GcPdf (which provides PDF export for AR) looks for system fonts in the following directories and their subdirectories:

"

“~/.fonts/”

“/usr/local/share/fonts/”

“/usr/share/fonts/”

"

So if you can create one of those directories inside your dockerfile, and put the fonts in that directory (or a subdirectory) - this should help. (I am not very familiar with Docker, but I think this should be possible, right?)

Please let me know whether this helps.

Thanks,

Dmitry.

Hello Dmitry!

Thanks for the answer. Its work!

Volume ```

/usr/share/fonts:/usr/share/fonts

You into can also install ``` ttf-mscorefonts-installer ``` directly into container. I suppose that the assembly should look like this, but I can't check it because I don't have a license (I'm considering your project) Dockerfile

ARG PRODUCT_ID

ARG PRODUCT_SERIAL_KEY

FROM mcr.microsoft.com/dotnet/sdk:5.0.102-alpine3.12-amd64 AS sdk

ENV PRODUCT_ID ${PRODUCT_ID}

ENV PRODUCT_SERIAL_KEY ${PRODUCT_SERIAL_KEY}

RUN apk --no-cache add --update nodejs npm

https://www.grapecity.com/componentone/docs/license/online-license/licensing-aspnet-apps-on-docker.html

RUN dotnet tool install -g GrapeCity.LicenseManagerTool

ENV PATH=“$PATH:/root/.dotnet/tools”

WORKDIR /app

COPY WebDesigner_MVC_Core.sln WebDesigner_MVC_Core.csproj ./

RUN dotnet restore

COPY . .

RUN gclm “${PRODUCT_ID}” -a “${PRODUCT_SERIAL_KEY}”

RUN dotnet publish ./WebDesigner_MVC_Core.csproj

–runtime alpine-x64

–self-contained true

–configuration Release

/p:PublishTrimmed=true

/p:PublishSingleFile=true

–output ./out

|| gclm “${PRODUCT_ID}” -d “${PRODUCT_SERIAL_KEY}”

FROM mcr.microsoft.com/dotnet/runtime-deps:5.0.2-alpine3.12-amd64 as runtime

do need nodeje in runtime?

RUN apk --no-cache add --update nodejs npm

RUN apk --no-cache add --update msttcorefonts-installer fontconfig &&

update-ms-fonts &&

fc-cache -f

COPY --from=sdk /app/out ./app

WORKDIR /app

ENTRYPOINT [“./WebDesigner_MVC_Core”]

https://www.grapecity.com/activereportsnet/docs/v14/online/licensing-with-pipelines.html

CMD [“&”, “gclm”, “${PRODUCT_ID}”, “-d”, “${PRODUCT_SERIAL_KEY}”]

Or tye way. docker-compose.yml

version: “3.9”

services:

reports:

image: webdesigner-mvc-core:1.0.0

restart: always

volumes:

- reports_resources:/app/resources

- reports_datasets:/app/datasets

# line below fix font error if fonts not installed into container

- /usr/share/fonts:/usr/share/fonts

ports:

- 80:80

- 443:443

volumes:

reports_resources:

driver: local

reports_datasets:

driver: local

reports_templates:

driver: local

reports_aspnet_keys:

driver: local

Run

dotnet tool install -g Microsoft.Tye --version “0.6.0-alpha.21070.5”

tye init

tye build

for debian

apt install ttf-mscorefonts-installer -y

docker-compose up -d

Thanks!
