主题：[求助]Savetopdf 生成的pdf修改问题

那你就直接用vba存为图片，如

Dim App As New MSExcel.Application
try
    Dim Wb As MSExcel.WorkBook = app.WorkBooks.open("d:\test.xls")
    Dim Ws = wb.WorkSheets(1)
    Dim rg As MSExcel.Range = ws.UsedRange
   
    rg.copy
    'app.visible = True
    ClipBoard.GetImage.save("d:\aaa.wmf")
    app.quit
catch ex As exception
    msgbox(ex.message)
    app.quit
End try

修改pdf权限吧，参考代码

Dim reader As New iTextSharp.text.pdf.PdfReader("d:\test.pdf")
Dim document As New  iTextSharp.text.Document(reader.GetPageSizeWithRotation(1))
Dim n As Integer = reader.NumberOfPages
Dim baos As New IO.FileStream("d:\test2.pdf", IO.FileMode.Create, IO.FileAccess.Write)
Dim copy As New  iTextSharp.text.pdf.PdfCopy(document, baos)

Dim ownerPassword = Encoding.default.GetBytes("12345")
Dim permissions = iTextSharp.text.pdf.PdfWriter.ALLOW_COPY Or iTextSharp.text.pdf.PdfWriter.ALLOW_MODIFY_CONTENTS Or iTextSharp.text.pdf.PdfWriter.ALLOW_PRINTING
copy.setEncryption(Nothing, ownerPassword, permissions,False)
copy.ViewerPreferences =  iTextSharp.text.pdf.PdfWriter.HideToolbar Or iTextSharp.text.pdf.PdfWriter.HideMenubar Or iTextSharp.text.pdf.PdfWriter.HideWindowUI
'往pdf中写入内容
document.Open()
For i As Integer = 1 To n
    Dim page As  iTextSharp.text.pdf.PdfImportedPage = copy.GetImportedPage(reader, i)
    copy.AddPage(page)
Next
document.Close()
reader.Close()

你去打开123.pdf这个文件测试啊。

1、请截图说明可以怎么编辑？

2、除了这些 iTextSharp.text.pdf.PdfWriter.ALLOW_COPY Or iTextSharp.text.pdf.PdfWriter.ALLOW_MODIFY_CONTENTS Or iTextSharp.text.pdf.PdfWriter.ALLOW_PRINTING

还有如下权限，你可以加上看看

PdfWriter.ALLOW_ASSEMBLY、PdfWriter.ALLOW_FILL_IN、PdfWriter.ALLOW_MODIFY_ANNOTATIONS、PdfWriter.ALLOW_DEGRADED_PRINTING、PdfWriter.ALLOW_SCREENREADERS、PdfWriter.DO_NOT_ENCRYPT_METADATA

pdf文件发上来（原来的pdf以及生成的新的d:\123.pdf，一起发上）

试试改成

Dim reader As New iTextSharp.text.pdf.PdfReader("c:\test.pdf")
Dim document As New  iTextSharp.text.Document(reader.GetPageSizeWithRotation(1))
Dim n As Integer = reader.NumberOfPages
Dim baos As New IO.FileStream("c:\123.pdf", IO.FileMode.Create, IO.FileAccess.Write)
Dim copy As New  iTextSharp.text.pdf.PdfCopy(document, baos)

Dim ownerPassword = Encoding.default.GetBytes("12345")
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_SCREENREADERS,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_DEGRADED_PRINTING,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_MODIFY_ANNOTATIONS,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_FILL_IN,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_ASSEMBLY,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_COPY,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_MODIFY_CONTENTS,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_PRINTING,False)
copy.ViewerPreferences =  iTextSharp.text.pdf.PdfWriter.HideToolbar Or iTextSharp.text.pdf.PdfWriter.HideMenubar Or iTextSharp.text.pdf.PdfWriter.HideWindowUI
'往pdf中写入内容
document.Open()
For i9 As Integer = 1 To n
    Dim page As  iTextSharp.text.pdf.PdfImportedPage = copy.GetImportedPage(reader, i9)
    copy.AddPage(page)
Next
document.Close()
reader.Close()

执行这段代码后没问题，请认真测试

Dim reader As New iTextSharp.text.pdf.PdfReader("c:\test.pdf")
Dim document As New  iTextSharp.text.Document(reader.GetPageSizeWithRotation(1))
Dim n As Integer = reader.NumberOfPages
Dim baos As New IO.FileStream("c:\123.pdf", IO.FileMode.Create, IO.FileAccess.Write)
Dim copy As New  iTextSharp.text.pdf.PdfCopy(document, baos)

Dim ownerPassword = Encoding.default.GetBytes("12345")
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_SCREENREADERS,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_DEGRADED_PRINTING,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_MODIFY_ANNOTATIONS,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_FILL_IN,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_ASSEMBLY,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_COPY,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_MODIFY_CONTENTS,False)
copy.setEncryption(Nothing, ownerPassword, iTextSharp.text.pdf.PdfWriter.ALLOW_PRINTING,False)
copy.ViewerPreferences =  iTextSharp.text.pdf.PdfWriter.HideToolbar Or iTextSharp.text.pdf.PdfWriter.HideMenubar Or iTextSharp.text.pdf.PdfWriter.HideWindowUI
'往pdf中写入内容
document.Open()
For i9 As Integer = 1 To n
    Dim page As  iTextSharp.text.pdf.PdfImportedPage = copy.GetImportedPage(reader, i9)
    copy.AddPage(page)
Next
document.Close()
reader.Close()
