I'm converting my legacy annotation to web annotation. However font size looks very large in web viewer. After reading the following link https://www.leadtools.co...ac/annfont-fontsize.html I did some conversion manually in font size for all childrens in the annotation container as shown in the below code.

Here is my code:
Code:

XDocument rootXmllDocument;
string GetLicensePath = System.Web.HttpContext.Current.Server.MapPath("~");
string licenseFilePath = Path.Combine(GetLicensePath, "License", "LEADTOOLS.lic");
string licenseKeyFilePath = Path.Combine(GetLicensePath, "License", "LEADTOOLS.lic.key");
string developerKey = string.Empty;
using (StreamReader reader = new StreamReader(licenseKeyFilePath))
{
    developerKey = reader.ReadToEnd();
}
try
{
    RasterSupport.SetLicense(licenseFilePath, developerKey);
    if (RasterSupport.KernelExpired)
    {
        throw new Exception("LEADTOOLS License has Expired!");
    }
    string rootXmlString = "";
    int PageNumber;
    AnnContainer[] containers = new AnnContainer[annotationPathInfo.AnnotationFilePathList.Count];
    AnnCodecs annCodecs = new AnnCodecs();
    int i = 0;
    foreach (var annFilePath in annotationPathInfo.AnnotationFilePathList)
    {
        var annFile = new FileInfo(annFilePath);
        string fileExt = annFile.Extension;
        double dpiX = 96.0;
        double dpiY = 96.0;

        using (var codecs = new RasterCodecs())
        {
            if (!string.IsNullOrEmpty(annotationPathInfo.DocExtension))
            {
                codecs.Options.Load.Name = $"anything.{annotationPathInfo.DocExtension}";
            }
            string[] nameParts = annFile.Name.Split('.');
            PageNumber = int.Parse(nameParts[1]);
            RasterImage image = codecs.Load(annotationPathInfo.DocumentPath, PageNumber);

            double height = image.ImageHeight * (720 / (double)image.YResolution);
            double width = image.ImageWidth * (720 / (double)image.XResolution);

            if (image != null)
            {
                dpiX = image.XResolution;
                dpiY = image.YResolution;
            }

            var tempContainer = annCodecs.LoadAll(annFile.FullName, dpiX, dpiY).First();
            tempContainer.PageNumber = PageNumber;
            tempContainer.Size = new LeadSizeD(width, height);
            tempContainer.Mapper.MapResolutions(image.XResolution, image.YResolution, image.XResolution, image.YResolution);
            tempContainer.Resize(new LeadSizeD(width, height), AnnResizeContainerFlags.ResizeObjects, AnnResizeMode.Stretch);

            foreach (var child in tempContainer.Children)
            {
                //child.FixedStateOperations = AnnFixedStateOperations.FontSize;
               // Manual conversion I did to reduce font size. Is this correct approach?
                child.Font.FontSize = child.Font.FontSize * (child.Font.FontSize / 72);
            }

            containers[i] = tempContainer;
            image.Dispose();
        }

        i++;
    }
    rootXmlString = annCodecs.SaveAllToString(containers, AnnFormat.Annotations);
    rootXmllDocument = XDocument.Parse(rootXmlString);

}
catch (Exception ex)
{
    throw new Exception("Annotation Conversion Failed - " + ex.Message);
}

return rootXmllDocument.ToString(SaveOptions.DisableFormatting);



Please assist if this is correct or this can be done by configuring some options?

Hello Abdul,

The method you are using looks like it does adjust the AnnFont to the size you desire. However, with the said, the AnnFont should not change when converting legacy annotations to the v20 annotations xml format. If you would like, I can take a look into this if you would like. I would need to see the legacy .ann file to do so.

I look forward to your reply.

Thanks

Dear Matt,

Sure. I'll attach the .ann file for your reference. I have a question. I have ceated a Text Annotation in legacy with text font size to 36. In the converted XML the font size is also 36. But both have the same units? Or different units? In this case 36 has the unit of Pt in legacy desktop annotations and Px in web annotations? Which means the rendered text size will be visually different in both places. Am I correct?

Here is the legacy .ann file.

Hello Abdul,

I am still currently working on replicating this issue that you are having. The different units, Pt and Px, I assume are points and pixels respectively. However, with that said the AnnTextObject size should not change from v13 legacy to v20 XML format. I will continue looking into this and revert back to you when I have an update. Let me know if you have any questions or comments in the meantime.

Thanks

Hello Abdul,

I am still currently working on your case. In the meantime, can you send me screenshots showing the font size difference from v13 desktop to v20 web?

Hello Abdul,

I received an update regarding your current reported issue. The issue could be stemming from setting FontRelativeToImageDpi to true.
https://www.leadtools.co...trelativetoimagedpi.html
This setting is true by default. Please see the screenshots attached below.

Please test this and let me know your results. Also, let me know if you have any questions about the information above.

Dear Matt,

I have set the FontRelativeToImageDpi = false. But still getting the same font size.

Here is the code change:

Code:

var tempContainer = annCodecs.LoadAll(annFile.FullName, dpiX, dpiY).First();
tempContainer.PageNumber = PageNumber;
tempContainer.Size = new LeadSizeD(width, height);
tempContainer.Mapper.MapResolutions(image.XResolution, image.YResolution, image.XResolution, image.YResolution);
tempContainer.Mapper.FontRelativeToImageDpi = false;
tempContainer.Resize(new LeadSizeD(width, height), AnnResizeContainerFlags.ResizeObjects, AnnResizeMode.Stretch);

// Temporary fix for font size issue
//foreach (var child in tempContainer.Children)
//{
//    //child.FixedStateOperations = AnnFixedStateOperations.FontSize;
//    child.Font.FontSize = child.Font.FontSize / 2;
//}

containers[i] = tempContainer;
containers[i].Mapper.FontRelativeToImageDpi = false;
image.Dispose();


Please can you assist on what I'm doing wrong?

Thanks,
Abdul Rahman

Hello Abdul,

I am not seeing anything that is indicating that you are not setting the property correctly. Can you send me a screenshot of a side by side comparison of v13 and v20 with the setting disabled? I want to see what you are getting on your end so I can pass that along to our engineers.

Thanks
