Required new type of Annotation

annotation.jpeg (47.2 KB)

Hello Team,
In my project I have a new requirement of implementing a new kind of annotation where we have to add a box annotation along with the Text.

Please find the attachment where clearly describes the requirement.

Regards,
Pramod

@pramodsahu

There is a lot of text in your snapshot. Do you mean the text “B” on the right side of the box or some other text with the blue box?

@mudassir.fayyaz
Thanks for your reply.
My requirement is the text “B” on the right side with the Box.

@pramodsahu

You can create a rectangle with any fill color and add text stamp at any location of page.

Add Text stamps in PDF programmatically

@mudassir.fayyaz
Let my try as per above.

Thanks

@pramodsahu

Sure. Please try and then share your feedback.

@mudassir.fayyaz

Thanks for the support.
I have implemented as followed by the above given links and also created the the POC for my project its working fine foe me as below
image.png (33.0 KB)

But the same code while i am using in the real project I don’t see text stamp. However, if I copy the TextStamp area in PDF document and paste into notepad, I can see the text.
I am using Aspose.Pdf 21.9.0

FormattedText text = new FormattedText(txt);
TextStamp stamp = new TextStamp(text);
stamp.TextState.FontSize = 30.0F;
stamp.TextState.FontStyle = FontStyles.Bold;
stamp.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Aqua);
stamp.XIndent = LLX - 20;
stamp.YIndent = LLY + (rectHeight / 3);
doc.Pages[1].AddStamp(stamp);

FYI i also made the Background = false;

But still facing the same blank screen.

@pramodsahu

It’s good to know that shared articles were helpful. I request you to share a sample application for our investigations.

@mudassir.fayyaz

This is the below code I have implemented in my POC and the annotated pdf showing proper text stamp.But while I have implemented the same in the project the text stamp not showing as i have mentioned above.

Its a urgnet requirement please give me the solution.

I request you to share a sample application as ZIP because your code looks to be using some sample files as well.

@mudassir.fayyaz
I can not able to share the whole application but below is my sample code which i have used in my application.

string dataDir = “F:/Pams/PrintPDFApi/PrintPDFWebApi/AnnotionPDF/”;
FormattedText text = new FormattedText(“B”);
Document doc = new Document(dataDir + “document.pdf”);
TextStamp stamp = new TextStamp(text);
stamp.TextState.FontSize = 50.0F;
stamp.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Red);
stamp.Background = false;
stamp.XIndent = 500;
stamp.YIndent = 600;
stamp.TextState.FontStyle = FontStyles.Bold;
stamp.TextState.RenderingMode = TextRenderingMode.FillThenStrokeText;
dataDir = dataDir + “annotateddocument.pdf”;
doc.Save(dataDir);

document that i have used is below
document.pdf (2.0 MB)

@pramodsahu

Please add this line to your code before saving the document and share your feedback.

doc.Pages[1].AddStamp(stamp);

I have added the same but still facing the same issue

@mudassir.fayyaz
In your forum I could not able to upload the whole project in ZIP because the ZIP folder size is more than 50 MB.
So I have uploaded the controller where I have created all along with the JSON file.

1)Create a .Net Core project and create a controller.
2)Create a folder in the solution name it as “JSONPdf” and put the attached json file in the folder.
2)Create 2 more folder name as “Images” where the converted JSON to Images file will be store and folder “downloadedPDF” where the annotated file will be store.
The add the below running code inside the controller and check.
Json File
document.zip (2.5 MB)

Controller:
PDFController.zip (3.2 KB)

Structure
Captured.PNG (24.3 KB)

Output what I got which is not required
Screenshot.png (118.6 KB)

My expected result should be
Expected.PNG (35.4 KB)

Please find all and provide me the proper solution>

Expecting the good result.

@pramodsahu

Please share the ZIP file using Google Drive, One Drive or any file sharing service.

@mudassir.fayyaz
I have uploaded the Project Please find the same and give me the solution.

PrintPDFWebApiNew.zip (4.7 MB)

@pramodsahu

The text is added on the page but it goes behind the image. I suggest you to try Add Image stamps in PDF approach for adding images or use Free Text Annotation and share your feedback.
