[atirtahirgroupdocs]

This issue is raised in https://forum.groupdocs.com/t/consistently-facing-issue-the-process-cannot-access-the-file-because-it-is-being-used-by-another-process-in-asp-net-mvc/9574. Hi, When a file is uploaded, edited and save button is pressed, application gives an exception. Please have a look at the following screenshots.

Below is the sample code:

[HttpPost]
        [Route("annotate")]
        public HttpResponseMessage AnnotateAsync(AnnotationPostedDataEntity annotateDocumentRequest)
        {
            AnnotatedDocumentEntity annotatedDocument = new AnnotatedDocumentEntity();
            try
            {
                // get/set parameters
                string documentGuid = annotateDocumentRequest.guid;
                string password = annotateDocumentRequest.password;
                string documentType = SupportedImageFormats.Contains(Path.GetExtension(annotateDocumentRequest.guid)) ? "image" : annotateDocumentRequest.documentType;
                string tempPath = GetTempPath(documentGuid);

                AnnotationDataEntity[] annotationsData = annotateDocumentRequest.annotationsData;
                // initiate list of annotations to add
                List<AnnotationBase> annotations = new List<AnnotationBase>();

                using (GroupDocs.Annotation.Annotator annotator = new GroupDocs.Annotation.Annotator(documentGuid, GetLoadOptions(password)))
                {
                    IDocumentInfo info = annotator.Document.GetDocumentInfo();

                    for (int i = 0; i < annotationsData.Length; i++)
                    {
                        AnnotationDataEntity annotationData = annotationsData[i];
                        PageInfo pageInfo = info.PagesInfo[annotationsData[i].pageNumber - 1];
                        // add annotation, if current annotation type isn't supported by the current document type it will be ignored
                        try

Hi @atirtahirgroupdocs, we can't reproduce such issue using our .jpg file on sample app version from the master branch. So could you please add information about annotation type that was adding by the user and attach .jpg-file on which issue was met.

[ImSMRizwan]

Dear @kegor, but I am facing an issue Kindly Check the video:

=> https://youtu.be/UnEKwhrDM1w

[kegor]

Hi @ImSMRizwan, I tried to reproduce the problem using, I guess, one of yours images, and mentioned in video annotations types, but still I didn't met the issue (please take a look at the gif-animation).

I would like to mention that my manual test was made on master-branch of the current sample app (https://github.com/groupdocs-annotation/GroupDocs.Annotation-for-.NET-MVC).

I'll suggest you to try reproduce same steps on sample app build from re-cloned repository or from master-branch code downloaded as zip-archive.

[ImSMRizwan]

Dear @kegor , Thanks for your valuable comment. The save button is working fine. Now, I find another bug, kindly check the gif animation

After save I download the image file but it's not showing my editing on the downloaded image. kindly check it also. I am waiting for your response. it would be best for me if you reply soon.

best regards

[kegor]

Hi @ImSMRizwan.

Thank you for your request. We work on your issue and when it will be fixed we will notify you here.

[kegor]

Hi @ImSMRizwan,

The issue has been resolved. Please checkout latest commit from master branch GroupDocs.Annotation-for-.NET-MVC.

Best Regard Egor.

[ImSMRizwan]

Dear @kegor, I found 2 more issues, kindly check the video => https://youtu.be/UJZS_Cd1_AQ

Dear support, any timeline on these issues. We are interested in purchasing this tool, can you please let us know the timelines?

[kmehmoodkhan]

Any tentative timeline? because we have to make a decision on the tool selection, your reply will help us finalize our decision. Thanks

[bobkovalex]

Hi @kmehmoodkhan

In order for us to provide any ETA we need to investigate the issue. We're already working on it. So we will get back to you ASAP.

Thanks.

Hi @ImSMRizwan,

I tried to reproduce the problem using our multi-page PDF-file and all available now annotations types and I downloaded resulted file with all annotations applied (please take a look at these gif-animations: adding and viewing).

If you still facing with the issue could you please share your PDF-file and reproducing steps.

Thank you, Egor.

[kmehmoodkhan]

Hi @kegor, thanks for the reply. Everything works, in the same way, the way you have shown in the video but after completing these steps when we save the annotated pdf, some of the annotations are lost as @ImSMRizwan mentioned. Can you please try to save the document on a local drive or any other storage like google drive etc and then see whether all the annotations are still there or disappear? thanks

[ImSMRizwan]

Dear @kegor, I am still facing issues.

Hi @kmehmoodkhan @ImSMRizwan

We've released an improvement which should fix document not opening issue, please checkout latest commit from master branch.

As for not all annotations are saved/exported we are working on the fix and will release it soon (ASAP).

Thanks.

Regards, Alex

[bobkovalex]

@kmehmoodkhan @ImSMRizwan

We've released another improvement which should fix an issue with missing annotations. Please note that Google Drive preview might now support all annotation types, instead open document locally using Adobe or other similar application.

Make sure to:

1. Checkout latest commit from master branch;
2. Apply license before running GroupDocs.Annotation-for-.NET-MVC; In case if you do not have license yet, you can request a temporary licence from here.

I have checked, But still facing missing some annotations options. kindly check the GIF below:

@kmehmoodkhan FYI

@ImSMRizwan

Please check annotated document locally using Adobe Reader instead of Chrome built-in PDF viewer.

[ImSMRizwan]

@bobkovalex Thanks for your comment. let me check.

[ImSMRizwan]

@bobkovalex Thanks for your support, above mentioned issues are fixed and working fine, But Now I am facing another issue, I want to share the issue, Kindly check the GIF file below.

Hi @ImSMRizwan,

The issue with positions of annotations added on image-files mentioned in following comment has been partially resolved. Please checkout latest commit from master branch GroupDocs.Annotation-for-.NET-MVC.

However, there are still two issues with annotations length and text underline annotation position. We expect that they will be fixed in the next library version.

Thank you, Egor.
