[reportlab-users] Newbie -- How to center text in a paragraph

[Jim Steil]

Hi:



I'm REAL new to reportlab and am trying to center my text in a paragraph.
I've found the XML markup and have the following code:



styles = getSampleStyleSheet()

style = styles['Normal']

s5Text1 = '<para alignment="1"><i><b>QLF PRESERVATIVES AND MOLD
INHIBITORS</b></i></para>'

section5P1 = Paragraph(s5Text1, style)

story5 = []

story5.append(section5P1)

frame5.addFromList(story5, canvas)



And here is the error I'm getting:



Traceback (most recent call last):

File
"C:\Python24\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py",
line 310, in RunScript

exec codeObject in __main__.__dict__

File "C:\svn\Python Misc\priceListN.py", line 251, in ?

processPlant(plant, priceList, priceListDate)

File "C:\svn\Python Misc\priceListN.py", line 190, in processPlant

printBacker(canvas, plantNumber)

File "C:\svn\Python Misc\priceListN.py", line 228, in printBacker

section5P1 = Paragraph(s5Text1, style)

File "C:\Python24\reportlab\platypus\paragraph.py", line 445, in __init__

self._setup(text, style, bulletText, frags, cleanBlockQuotedText)

File "C:\Python24\reportlab\platypus\paragraph.py", line 469, in _setup

raise "xml parser error (%s) in paragraph beginning\n'%s'"\

xml parser error (alignment: invalid value 1) in paragraph beginning

'<para alignment="1"><i><b>QLF '



I'm obviously missing the boat on something here but I can't seem to find
it. Any help would really be appreciated.



-Jim

You can try using the "alignment" property of ParagraphStyle, or use
a style that is already aligned (like the 'Title' one).

Is there a doc somewhere that details all of the styles available?

You can take a look at the userguide (chapter 6 describes
paragraphs and styles), also you can see all the styles
available on getSampleStyleSheet() through .list() method

INHIBITORS</b></i></para>'

Try '<para alignment="center">'. In xml you can use 'left', 'center',
'centre' (for reactionary Brits), 'right' and 'justify'.

But if you want the whole paragraph to be bold, italic and centered,
it's more efficient to make a style with those properties and create the
paragraph with that style. Typically you want about 10 styles in a
document, and only need the XML markup for intra-paragraph changes. To
go this way we DO use numeric constants and TA_CENTER is 1.

from reportlab.lib.styles import ParagraphStyle
from reportab.lib.enums import TA_LEFT, TA_RIGHT, TA_CENTER, TA_JUSTIFY
sty = ParagraphStyle(name="myStyle", alignment="TA_CENTER",
fontName="Helvetica-BoldOblique")
para = Paragraph(text, style=sty)

Ok, I've got that all working now, but now I have a couple of other 'funny'
things going on.

1. I have 3 paragraphs in a frame. I set the style on the first one to be
centered and set the other 2 paragraphs to be left justified. But, all
three paragraphs are centered.

section5P1 = Paragraph(s5Text1, styleCentered)
section5P2 = Paragraph(s5Text2, style)
section5P3 = Paragraph(s5Text3, style)
story5 = []
story5.append(section5P1)
story5.append(Spacer(1, 0.15*inch))
story5.append(section5P2)
story5.append(Spacer(1, 0.15*inch))
story5.append(section5P3)
frame5.addFromList(story5, canvas)

2. In my paragraph text, I was using the <b> and <i> tags to bold and
italicize. It was working fine until I changed my font to Arial. Now none
of my font decoration stuff is working.

pdfmetrics.registerFont(TTFont('Arial', 'arial.ttf'))
pdfmetrics.registerFont(TTFont('Arial Bold', 'arialbd.ttf'))
pdfmetrics.registerFont(TTFont('Arial Bold Italic', 'arialbi.ttf'))
pdfmetrics.registerFont(TTFont('Arial Italic', 'ariali.ttf'))
baseFont = 'Arial'
styleCentered = styles['Normal']
styleCentered.alignment = 1
styleCentered.fontName = baseFont
text = '<b>This is my bold text</b>'
paragraph = Paragraph(text, styleCentered)

When I do this, my text is not bold. If I replace the <b> tags with <font
face="Arial Bold"> then it works.

Looking below, my hunch is that you have modified the normal style
in the standard stylesheet to be centered, and 'styleCenteredd' and
'style' are references to the same centered object. You should actually
create a new style object.

baseFont = 'Arial'
styleCentered = styles['Normal']
styleCentered.alignment = 1
styleCentered.fontName = baseFont
text = '<b>This is my bold text</b>'
paragraph = Paragraph(text, styleCentered)

What you have done here is to register 4 fonts, but as yet it has no
knowledge that they are in the same 'family', so it doesn't know what to
do when encountering a <b> or <i> tag. The system has builtin knowledge
of the 'font families' for Helvetica, Courier and Times but no others.
So you need to tell it which combinations of facename/bold/italic map to
which actual font files:

from reportlab.lib.fonts import addMapping
addMapping('Arial', 0, 0, 'Arial')
addMapping('Arial', 0, 1, 'Arial Italic')
addMapping('Arial', 1, 0, 'Arial Bold')
addMapping('Arial', 1, 1, 'Arial Bold Italic')

The user guide mentions this for Rina, which is a poor example
as there were no variants and all we wanted to do was allow <b> and <i>
through harmlessly.

Thanks everyone for all the help. Now I've got enough to go on to get it
all to work the way I need it to.

Ok, I tried the addMappings for the Arial font. Now it works in that it
does bold and italicize when asked, but it is doing it with the wrong font.
I have the following code:

pdfmetrics.registerFont(TTFont('Arial', 'arial.ttf'))
pdfmetrics.registerFont(TTFont('Arial Bold', 'arialbd.ttf'))
pdfmetrics.registerFont(TTFont('Arial Bold Italic', 'arialbi.ttf'))
pdfmetrics.registerFont(TTFont('Arial Italic', 'ariali.ttf'))

addMapping('Arial', 0, 0, 'Arial')
addMapping('Arial', 0, 1, 'Arial Italic')
addMapping('Arial', 1, 0, 'Arial Bold')
addMapping('Arial', 1, 1, 'Arial Bold Italic')

Then in my text I used the <b> and <i> tags to turn it off and on. The
problem is not that it is bolding and italicizing the text, but not with the
Arial font. It is reverting back to a Times-Roman (I think) font.

Any ideas of what I'm doing wrong?

In this example change

to

Assuming you have imported the name. In Python-land we use a numeric constant (you could use 1 but it is cryptic) and in xml-land we use "center",

Hope this gets you there,

Well, that fixed everything. The other message regarding the font not

styles = getSampleStyleSheet()
style = styles['Normal']
s5Text1 = '<para alignment="1"><i><b>QLF PRESERVATIVES AND MOLD
INHIBITORS</b></i></para>'

Try '<para alignment="center">'. In xml you can use 'left', 'center',
'centre' (for reactionary Brits), 'right' and 'justify'.

But if you want the whole paragraph to be bold, italic and centered,
it's more efficient to make a style with those properties and create the
paragraph with that style. Typically you want about 10 styles in a
document, and only need the XML markup for intra-paragraph changes. To
go this way we DO use numeric constants and TA_CENTER is 1.

from reportlab.lib.styles import ParagraphStyle
from reportab.lib.enums import TA_LEFT, TA_RIGHT, TA_CENTER, TA_JUSTIFY
sty = ParagraphStyle(name="myStyle", alignment="TA_CENTER",
fontName="Helvetica-BoldOblique")
para = Paragraph(text, style=sty)
