Font size of the char given by pdfplumber is diffrent from the actual font size.

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

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?

[suyogchadawar]

Thanks this worked for me

It does seem, though, that you can arrive at the Adobe-determined font size by dividing width by adv.

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.

[suyogchadawar]

ok sure thanks
