Hi, the font size given by pdfplumber does not match with the font size given by adobe acrobat dc pro. Is there any correlation between them?
Can we get font color from pdfplumber?

the font size given by pdfplumber does not match with the font size given by adobe acrobat dc pro.

Can you provide the following?:

• An example of a PDF that displays this behavior
• The output you get
• The font size that Adobe Acrobat indicates

Can we get font color from pdfplumber?

In pdfplumber output for the text/characters of interest, do you see the fill and stroke attributes? If not, can you paste the pdfplumber object-representation for a character that you believe should have color information but doesn't?

{'adv': Decimal('0.507'), 'fontname': 'QYZTAI+Calibri-Light', 'doctop': Decimal('83.708'), 'y1': Decimal('708.292'), 'bottom': Decimal('100.704'), 'text': u'1', 'top': Decimal('83.708'), 'object_type': 'char', 'height': Decimal('16.996'), 'width': Decimal('7.057'), 'page_number': 1, 'upright': True, 'y0': Decimal('691.296'), 'x0': Decimal('72.000'), 'x1': Decimal('79.057'), 'size': Decimal('16.996')}

i got this output by using following code:

` file_read=pdfplumber.open(in_file)

for temp in file_read.pages:

dict_char = temp.chars

for t in dict_char:

    print(t) `

hi @jsvine , did you get the chance to look into this?

[jsvine]

Hi, @suyogchadawar. I don't know exactly what's causing this issue; pdfplumber depends on pdfminer.six for text extraction. It does seem, though, that you can arrive at the Adobe-determined font size by dividing width by adv. In your example, that'd be: 7.057 / 0.507 = 13.919.

See here for the computation of the adv attribute: https://github.com/euske/pdfminer/blob/master/pdfminer/layout.py#L230

Thanks this worked for me

but still I am not able to find color of the character from pdfplumber.

[jsvine]

It appears that character color is not currently accessible via pdfplumber. I'll see if there's a way to add that in future versions.

ok sure thanks
