Issue with images and page endings

[Fuzzyman]

I have an issue with images and I wonder if it is a known issue, or
possibly already fixed.

My installed version of rst2pdf is 0.11. I'm on Mac OS X with Python
2.5.

I always specify an explicit size for images (usually just one of the
two dimensions and rst2pdf does a good job of keeping the scale). If
an image ends up near the end of a page and doesn't fit then instead
of moving it to the next page it scales it down - overriding the
explicit size I have specified and sometimes resulting in a tiny
image.

I'm currently having to move text around to keep the images from being
near the end of pages! I see a message similar to below output when
this happens:

[WARNING] flowables.py:68 image images/packages.png is too tall
for the frame, rescaling

I also regularly get a ton of messages as per below with no indication
what caused them:

[WARNING] flowables.py:443 BoundByWidth too wide to fit in frame:
<BoundByWidth at 0x1d8cf80> size= maxWidth=0x
[WARNING] flowables.py:443 BoundByWidth too wide to fit in frame:
<BoundByWidth at 0x1d8cf80> size= maxWidth=0x

All the best,

Could you send me a test case? As simple as you can, please :-)

These are usually caused by literal blocks (say, code samples) which don't fit
in the page width, and are usually harmless.

I am having the same kind of errors with images in documents. Here is
the text that I am working with:

==================
How to Enable /PAE
==================

1. Navigate to C:\ in Windows Explorer.
2. On the menu bar click *Tools->Folder* Options
#. Click on the View tab

#. Check the radio button for Show hidden files and folders
#. Make sure there is not a check in the Hide protected operating
system files box

#. You will get a pop up warning message saying:


.. image:: ./images/pae/image001.png
:align: center
:scale: 80

.. image:: ./images/pae/image003.png
:align: center
:scale: 80

4. Click OK
#. Locate the file in C:\ named boot.ini. It should now be visible
that the hidden files and operating system files options have been
selected.

.. image:: ./images/pae/image005.png
:align: center
:scale: 80

6. Right click on this file and select Properties
#. Uncheck the Read-only box and then click Apply

.. image:: ./images/pae/image007.png
:align: center
:scale: 80

8. Open the file with Notepad.exe
#. On the bottom line of the file add /PAE to the end of the line. It
should look like the following:

boot.ini::

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows Server 2003,
Enterprise" /fastdetect /NoExecute=OptOut /PAE

10. Save the file and close it.
#. Do the reverse of steps 6 and 7 and make the file *Read-only*
again.
#. Reboot the server. Once the server is back up verify that you can
now see all of the memory that is available to the system.



When I run rst2pdf file.txt I get:

Hi,

I'm seeing this same issue, where images near the bottom of the page generate the "too tall for the frame" error. 

I'm using rst2pdf 0.93, PIL 1.1.7, report lab 2.7. 

Has a solution been found for this?

Thanks,

Pete
