    <p>I'm trying to insert a barcode image into Reportlab. I know there are a lot of questions asked on this, but <strong>all of them assume</strong> that you already have the image file in the directory or on the filesystem.</p> <p>Due to the fact that Reportlab has issues with EAN13 barcodes, I decided to use another package called pyBarcode to generate the image for me.</p> <p>Initially I saved the image in a StringIO instance and passed it directly to <code>reportlab.platypus.flowables.Image</code> but that didn't seem to work. Then I read the documentation:</p> <blockquote> <p>Formats supported by PIL/Java 1.4 (the Python/Java Imaging Library) are supported.</p> </blockquote> <p>Does this mean that if I pass a PIL image, this should work? I got an exception when I tried the following:</p> <pre><code>&gt;&gt;&gt; import PIL &gt;&gt;&gt; from reportlab.platypus.flowables import Image &gt;&gt;&gt; fp = StringIO(the_barcode.getvalue()) &gt;&gt;&gt; barcode_image = PIL.Image.open(fp) &gt;&gt;&gt; doc = SimpleDocTemplate('barcode.pdf') &gt;&gt;&gt; story = [Image(barcode_image)] &gt;&gt;&gt; Traceback (most recent call last): File "create.py", line 57, in &lt;module&gt; main() File "create.py", line 24, in main save_pdf(fp, STYLE, ART, COLOR, SIZE) File "create.py", line 28, in save_pdf fp = StringIO(fp.getvalue()) File "/home/mark/.virtualenvs/barcode/local/lib/python2.7/site-packages/reportlab-2.6-py2.7-linux-i686.egg/reportlab/platypus/flowables.py", line 402, in __init__ if not fp and os.path.splitext(filename)[1] in ['.jpg', '.JPG', '.jpeg', '.JPEG']: File "/home/mark/.virtualenvs/barcode/lib/python2.7/posixpath.py", line 95, in splitext return genericpath._splitext(p, sep, altsep, extsep) File "/home/mark/.virtualenvs/barcode/lib/python2.7/genericpath.py", line 91, in _splitext sepIndex = p.rfind(sep) File "/home/mark/.virtualenvs/barcode/local/lib/python2.7/site-packages/PIL/Image.py", line 512, in __getattr__ raise AttributeError(name) AttributeError: rfind </code></pre> <p>Somehow PIL Image doesn't seem to work either. What should I pass as the first argument to Reportlab's Image function if I don't have the filename of the image (because my images are created in memory)?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
