Hello once again,
I have been using the EO.Pdf and being grateful for the hours saved in programming, but i have encountered a small problem in witch i hope it can be solved.
When printing, the final result (the pdf file) it does not allow Portuguese characters, it leaves a blank space in the spot where it should write the character.
Is there any way to use the following characters ( á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç ) and also in uppercase?
Thanks in advance.

Hi,
We are not aware of such problems. Do those characters display correctly when viewing with Acrobat Reader? Can you provide a small peice of test code to demonstrate the problem?
Thanks!

I have just tested in a test application the simplest i could do. A simple windows form application with: 1 Button: Called Button1 1 TextBox: Called TextBox1 No formats or properties were set to the form controls. And inserted the following code:
Code: Visual Basic.NET
Imports EO.Pdf.Acm
Imports EO.Pdf
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Create a new PdfDocument
Dim doc As PdfDocument = New PdfDocument()
'Create a new AcmRender object
Dim render As AcmRender = New AcmRender(doc)
render.SetDefPageSize(New System.Drawing.SizeF(12.0F, 9.5F))
Dim Linha1 As AcmParagraph = New AcmParagraph(New AcmText(TextBox1.Text))
Linha1.Style.FontSize = 20.0F
Linha1.Style.ForegroundColor = Color.DarkBlue
Linha1.Style.HorizontalAlign = AcmHorizontalAlign.Center
Dim Linha2 As AcmParagraph = _
New AcmParagraph(New AcmText("á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç"))
Linha2.Style.FontSize = 20.0F
Linha2.Style.ForegroundColor = Color.DarkRed
Linha2.Style.HorizontalAlign = AcmHorizontalAlign.Center
render.Render(Linha1, Linha2)
My.Computer.FileSystem.CreateDirectory("C:\Test_Aplication\")
Dim file_name_and_path As String = "C:\Test_Aplication\Listagem_TEST.pdf"
'Save the PDF file
doc.Save(file_name_and_path)
End Sub
End Class
I inserted in the TextBox1 Control the same input for the variable 'Linha2'. The .pdf file was created successfully and the result presented in the Acrobat Reader (version 9.3.2) is:
a a a a - e e e - . . . - o o o o - . . . - c a a a a - e e e - . . . - o o o o - . . . - c
--- The '.' (dots) are there only for replacing the missing/not visible chars---While i was posting this message i realize that when i copy the text and pasted it after (here) the result was:
á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç
Sooooo... I have a problem. The characters created in the pdf are correct but the visualization isn't , maybe its the font used that does not support the characters. Also tried to open the pdf with PhotoShop and the result was the same that with the Acrobat.

Hi,
Yes. The font must be the problem. The default font used by EO.Pdf is "Arial", which probably does not have those characters. Windows usually substitute those characters when displaying it, but Acrobat Reader does not.
In order to correctly display those characters, please try to explicitly set the correct font name on your Style object. We do not know which font to use because we do not know which font has those characters.
Thanks!

Sorry for the delay. I have tried several fonts witch are applied but they still don't show the characters right, the font types support the characters, I've checked, and i use them regularly also with Acrobat. Once again, the characters are correct and even some of the Fonts used can display some of the characters, but none of the fonts can display them all the strange part is that i use the same acrobat daily for other purposes and all of the fonts i tried have worked and the characters are displayed correctly. I have also tried to use ASCII char codes and directly from the textbox... same result. Wat can i do? The code used is the following:
Code: Visual Basic.NET
Imports EO.Pdf.Acm
Imports EO.Pdf
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Create a new PdfDocument
Dim doc As PdfDocument = New PdfDocument()
'Create a new AcmRender object
Dim render As AcmRender = New AcmRender(doc)
render.SetDefPageSize(New System.Drawing.SizeF(12.0F, 9.5F))
Dim str As String = Chr(231) & Chr(227) & Chr(218)
Dim Linha0 As AcmText = New AcmText("TESTE CHARS (" & str & " ||| " & Hex("0x00E7") & ")")
Dim Linha1 As AcmParagraph = New AcmParagraph(New AcmText("Arial (á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç)"))
Linha1.Style.FontSize = 20.0F
Linha1.Style.FontName = "Arial"
Linha1.Style.ForegroundColor = Color.DarkRed
Linha1.Style.HorizontalAlign = AcmHorizontalAlign.Center
Dim Linha2 As AcmParagraph = New AcmParagraph(New AcmText("Times New Roman (á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç)"))
Linha2.Style.FontSize = 20.0F
Linha2.Style.FontName = "Times New Roman"
Linha2.Style.ForegroundColor = Color.DarkRed
Linha2.Style.HorizontalAlign = AcmHorizontalAlign.Center
Dim Linha3 As AcmParagraph = New AcmParagraph(New AcmText("Verdana (á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç)"))
Linha3.Style.FontSize = 20.0F
Linha3.Style.FontName = "Verdana"
Linha3.Style.ForegroundColor = Color.DarkRed
Linha3.Style.HorizontalAlign = AcmHorizontalAlign.Center
Dim Linha4 As AcmParagraph = New AcmParagraph(New AcmText("Courier New (á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç)"))
Linha4.Style.FontSize = 20.0F
Linha4.Style.FontName = "Courier New"
Linha4.Style.ForegroundColor = Color.DarkRed
Linha4.Style.HorizontalAlign = AcmHorizontalAlign.Center
Dim Linha5 As AcmParagraph = New AcmParagraph(New AcmText("Microsoft Sans Serif (á à ã â - é è ê - í ì î - ó ò õ ô - ú ù û - ç)"))
Linha5.Style.FontSize = 20.0F
Linha5.Style.FontName = "Microsoft Sans Serif"
Linha5.Style.ForegroundColor = Color.DarkRed
Linha5.Style.HorizontalAlign = AcmHorizontalAlign.Center
Dim Linha6 As AcmParagraph = New AcmParagraph(New AcmText("FROM TEXTBOX: (" & TextBox1.Text & ")"))
Linha6.Style.FontSize = 20.0F
Linha6.Style.FontName = "Microsoft Sans Serif"
Linha6.Style.ForegroundColor = Color.DarkRed
Linha6.Style.HorizontalAlign = AcmHorizontalAlign.Center
'0xE7 0x00E7 #LATIN SMALL LETTER C WITH CEDILLA
render.Render(Linha0, Linha1, Linha2, Linha3, Linha4, Linha5, Linha6)
My.Computer.FileSystem.CreateDirectory("C:\Test_Aplication\")
Dim file_name_and_path As String = "C:\Test_Aplication\Listagem_TEST.pdf"
'Save the PDF file
doc.Save(file_name_and_path)
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim newViewer As New F_pdf
newViewer.file_to_load("C:\Test_Aplication\Listagem_TEST.pdf")
newViewer.Show()
End Sub
End Class

Hi,
Can you email us the following information in a zip file?
1. A simple piece of test code that uses our library to generates the PDF file with "problem" characters. This can be the same code you posted above;
2. The result PDF file generated by step 1. This is the PDF file with problem;
3. A simple PDF file that you created through other means that also contain the same "problem" characters but displays fine. This is the PDF file without problem;
We will PM you as to where to send these files. Once we have those files, we will look into the file and see what we can find.
Thanks!

Hello,
I encountered the same problem with Greek characters.
If my generated PDF's contents are in English, then everything works fine. But when I try to generate a PDF file with Greek text, each character is either printed as a blank space (which is the case for most characters) or as a number.
Is there support for Greek characters?
Thanks in advance.

Hi,
EO.Pdf should support any character as long as you have the font installed on your system. We have recently fixed an issue with character set. Please see your private message for the download location of the new build and let us know whether it works for you.
Thanks!

Hello,
I only now had the time to try the new build you sent me, just installed and made a quick test, so far everything is fixed correctly and all the characters are displayed correctly in the generated PDF.
Thanks once again for all the support and for the quickness for the solution.

Hello again, I also tried the new build, but unfortunately, the results didn't change for me. Here is a small example of what I'm trying to do:
Code: C#
PdfDocument doc = new PdfDocument();
AcmRender render = new AcmRender(doc);
AcmText text = new AcmText("ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ");
render.Render(text);
text = new AcmText("ΆΈΉΊΪΌΎΫΏ");
render.Render(text);
text = new AcmText("αβγδεζηθικλμνξοπρστυφχψως");
render.Render(text);
text = new AcmText("άέήίϊΐόύϋΰώ");
render.Render(text);
doc.Save(outputFileName);
The above is simply a test, in order to create a pdf file that contains all the characters of the greek alphabet. The result I should be getting can be found here: Desired result, created with Microsoft Word and printed as PDFCorresponding screenshotInstead, what I get is this: PDF generated by the above codeCorresponding screenshotI haven't set any font in my code, so I'm guessing that it defaults to Arial. The desired result is also created using Arial, so I don't think the problem has to do with the fonts. Is there something else I can try?
