[reportlab-users] Center align emoji's png images inside Paragraph

[Kaviraj Kanagaraj]

Hi 

I am trying to insert emjo's png inside Paragraph in reportlab. Basically image size Im using 18x18 with Paragraph Font size of 18 with center alignment. If Paragraph contains less than 6 pngs, All emojis are center aligned. But once its more than that Its no more center aligned.

How to add those pngs inside paragraph without disturbing the paragraph styles?

Thanks in advance

Can you please supply a simple example of the problem? I guess you are using an
18pt font and the img tag inside it, but I am not going to guess how this is
going wrong. I can make 18 x 18 images fairly easily, but exactly what the
layout is probably affects the problem. We have been asked before about emoji's
and I believe some fonts do have them, but using images would certaily be an
alternative.

I assume you mean vertically centred.

I tried the attached example in latest reportlab it seems to put the image in
the right place, but perhaps you can modify to show the problem you are having.

I'm not sure exactly what the problem is. There are 4 pages with centred
paragraphs drawn on them. Which is problematic and why?

I can only imagine that the last page which shows the text + images not centred
horizontally is the problem. I think that's because the last 'word' which
consists of nothing, but images is getting wrapped and the remnant first line
doesn't get centred properly. If that is your problem then I think this is a bug
in the break lines code. It seems we are assuming each img is a word and must be
followed by a space.

I'll see if there's an obvious fix.

Yea you are right thats the problem. But If you look closely except the first page none of them are center aligned correctly. Paragraph seems to be moving left as you increase the number of images. The problem may not only be in break lines code may also be in the way reportlab interpreting images. I mean even a single line paragraph is not properly center aligned if it contains images.. 

Thanks for looking into my problem.

OK the bug is that each image is being regarded as a word and our code assumes
that words are followed by spaces so the wrong width gets computed. I'm looking
into it.
