Python PDF + Pictures

Hi, dear Python Masters!

I wanna ask about the Python and PDF creating.

I have many photos, and I wanna make some "presentation" from these
photos, a "thumbnail" like document with one image per one page.

If I wanna make one document now I do this:
I execute a python script that create a html site with resized pictures,
and split this html site to 50 images per one html file.
Next I open these files in OpenOffice Writer by hand, and save them as
PDF document with poor quality (image compression 95%, image DPI 75).
This generates a medium sized PDF documents (2,5 - 5,6 MB for each) that
can opened everywhere (because of PDF format).

But I wanna automatize this process with python.
The technic that I will use is this:
1.) Collect the files in dirs.
2.) I process one dir in one time.
3.) I get the files.
4.) I resize them to max. 1024/768.
5.) I put the actual image file to the PDF document.
6.) After each 50. file I open new numbered PDF.
7.) Every picture placed in one page, and every page orientation set up
as the picture orientation (Portrait or Landscape).

The PDF must be parameterized to image compression 95%, and 75 or 96 DPI.

Do you knows about a PDF maker library with I can make this thing?

Or other technic to simplify the making?

Thanks for your help!

PIL can write PDFs, and it's clearly a good choice for image processing.

With HTML I have only one problem.
The HTML is not page specific language.
But I wanna use pages (for example: A4) with diff. orientation to show
images correctly.

But I try it if possible.

Thanks for your help:

You might also want to take a look at ReportLab. Its a PDF library
for Python. You can find it at http://www.repo...

Raj,

I'm till not sure what your target cell should look like but here are two
ideas:

Remove the single quote, retain the = but accept #NAME errors:
Sub Cleancolumn1()
For i = 1 To ThisWorkbook.Worksheets("Sheet1").Cells _
(Rows.Count, 14).End(xlUp).Row
Cells(i, 14) = Cells(i, 14).Value
Next i
End Sub


Remove the single quote, retain =, display without name error:
This means for a string like '123 yiu will end up with ="123"
I have no idea if this is acceptable.

Sub Cleancolumn2()
Dim A As String
Dim B As Long
For i = 1 To ThisWorkbook.Worksheets("Sheet1").Cells _
(Rows.Count, 14).End(xlUp).Row
A = Cells(i, 14)
B = Len(A)
Select Case B
Case 0
'do nothing
Case 1
'paste whatever is there
Cells(i, 14) = Cells(i, 14).Value
Case Is >= 2
If Left(Cells(i, 14), 1) = "=" Then
A = Right(Cells(i, 14), B - 1)
ThisWorkbook.Worksheets("Sheet1").Cells(i, 14) = "=" & A
ThisWorkbook.Worksheets("Sheet1").Cells(i, 14) = "=" & Chr(34) & A & Chr(34)
Else
Cells(i, 14) = Cells(i, 14).Value
End If
End Select
Next i
End Sub
