Invalid value for parameter "new_x"

[venturi123]

Hi @wudududu,

I met an error on Win10 by using evp .\ .\1.mp4. It did extract complete figures but did not generate a PDF file as expected.

Here is the traceback about this error.

After testing the demo.mp4 can work on win10. Maybe you can upload the 1.mp4.

Thanks for your rapid reply,

I've sent this video to your QQ e-mail.

Please check it.

I had the same problem. You can fix this by changing line 12 in "c:\users\wangq\miniconda3\lib\site-packages\video2ppt\images2pdf.py". instead of

pdf.cell(400, titleH, os.path.basename(image), 1, 1, 'C')

use

pdf.cell(400, titleH, os.path.basename(image), 1, ln=1, align='C')

or First, add this right below your import statement:

from fpdf.enums import XPos, YPos

and change line 12 to

pdf.cell(400, titleH, os.path.basename(image), 1, new_x=XPos.LMARGIN, new_y=YPos.NEXT, align='C')

I found that the problem was due to API changes in the FPDF library.

Yes, that's where the problem lies. It's work now!
