Word to PDF conversion Checkbox problem

Hi! Thanks for the fast solution!
But I have a problem with this solution (Editable fields on PDF document from DOCX - #2 by mario.gembox) I am using a .NET 7 app. And the line

var imageOptions = new GemBox.Document.ImageSaveOptions(GemBox.Document.ImageSaveFormat.Png);

It’s not working. The compiler indicate me:

“(“Image saving is supported only on WPF platforms (Windows OS).””

Do you have an alternative about this? To create the tempTextBox on the Save (tempTextBox.FormatDrawing().Save(imageStream, imageOptions))

Thanks!!
