Photo enhancement
by Gary Speer 21 Jul '02

21 Jul '02

Hi Ron - Did you happen to follow the thread in image-SIG about how to make Photo use the new Antialias filter in PIL 1.1.3? I know you prefer Imagemagik, but for us poor windoze folks that don't have a unix emulator, we are stuck with PIL. Anyway, Fredrick suggested adding the Antialias filter to the resize function in photo.py. I did and it works great. All of the generated images look 200% better! Please consider adding to the next release or posting a note on your page. It took a moment to figure out, but the syntax for using it is im.resize((width,height),PIL.Image.ANTIALIAS) Great product! I would love to see Photo work with ExternalFile's External Folder to batch read the source images on the file system and leave the image original (download version) at that location and have the option of sending the generated thumbnail there and all the other variations to the ExtFile folder - perhaps a checkbox next to the display sizes that indicates to save in the ExtFile folder under var or to save wherever the source was found (zodb or External folder). Part of why I mention this is that the contents of ExtFile's folder could be cleared like a cache, no risk of deleting a source image, no need to back it up, and if a display image is missing it can be regenerated on the fly. This helps a migration to a new server as the ExtFile folder can be ignored and the source images remain in their original file system folder context. Whole trees of images can be put into the file system and then External Folder can batch traverse and Photo can intercept each Image that External Folder is adding and add it as a photo instead as it does now. I think its just a change in the object filter settings to trigger the process on either form of added image. I really think this is worth a look because of the power of the image gallery that can be created and that maintainability is improved as whole branches of the directory tree are pruned and relocated. Simply refresh the metadata view of the file system via a traverse script that runs the external folder batch script and the new structure and all the displays are regenerated using settings acquired from the photo folder that is in the zodb portion of the path. I'm very impressed with both products and see the potential of large scale commerce-grade applications if the import can be simplified. On another subject, have you given any thought to pulling in the additional data fields in a jpeg typically written by digital cameras or captions and keyworks provided by image viewers as added properties of an imported photo? If not, are you aware of anyone having an enhancement or plugin for this? It seems like a straight forward loop through the properties that can be done when a photo is being added that has this extra data from the digital camera. I know I can spend time deconstructing the code to figure out where and how to add the attributes as each display onject is generated. I'm just wondering if you might already be thinking about this and know where the optimum insertion points might be to simply add all attributes found in the source file to each generated photo object. Please let me know your thoughts and suggestions. Thank you, Gary

ObjectManager and method doc strings
by David Beech 21 Jul '02

21 Jul '02

In order to do things like: http://192.168.1.190:10080/tssadmin/objectIds and see the object ids, OFS/ObjectManager.py needs doc strings in the methods that we want to call. It seems that the Zope distribution code doesn't have these doc strings for methods like objectIds, objectItems etc. Is this a security feature or is there another (preferred) way to execute methods like objectIds?

Looking for What's New documents
by Ross Boylan 21 Jul '02

21 Jul '02

With each new release of Python there is a very useful "What's new in Python xxx" document. Is there anything similar for Zope? I haven't been paying attention for awhile, and would like an easy way to catch up. The changes.txt contains some hints, but it seems to have several weaknesses: lots of irrelevant info, not enough info on how to use key changes, and it's not clear it has everything. The first example is the new session management. This is referred to in changes.txt, and there is some API documentation. But a little "this is how you use it" would be very helpful. Second, the security framework has changed (I think). __ac_permissions__ is out, SecurityInfo is in. I found a page on the wiki giving a vision statement, and the Zope Dev Guide illustrates its use. The page also describes how the old and the new might interact. First, I have no way of knowing how accurately the "vision statement" reflects what actually got translated into action. Second, I would like to have this information either part of the distribution, or more accessible. And, of course, I wonder what else I've missed.

Odd module import problem for product
by Pierce, Scott 21 Jul '02

21 Jul '02

I have two sunbox both running os 8, both running Zope 2.3.3, both running python 2.0.1. The product imports several python modules which in turn are initialized as objects but only the top-level module is registered. When you install the product into a folder it initializes the other objects or products. One of the modules cannot be imported on machine 2 but has no problems on machine 1. If the module or class file being imported had syntax errors would the syntax errors show in the zope control_panel under the broken product or would it just simply show the error in the parent product and simply refuse to acknowledge the module giving an import error? I know this is ambiquous but any thoughts on where to start looking as to why it would install on one identical box, identical code and not on the next? Could it be ZODB and Refresh has mangled something? Scott Pierce Sonopress US - Digital Services 828.658.6157

RE: [Zope] [HELP] Choice of a NT server
by Meilicke, Scott 21 Jul '02

21 Jul '02

I have read somewhere that zope does not take advantage of dual cpus on NT. My default install of 2.4.3 using zserver on NT4 confirms this. Is there a way to put that extra CPU to use? Scott -----Original Message----- From: D. Rick Anderson [mailto:ruger@comnett.net] Sent: Friday, July 19, 2002 10:09 AM To: zope(a)zope.org Subject: Re: [Zope] [HELP] Choice of a NT server We've used the Compaq ML-370 with Dual P3-1.13GHz cpus and 1GB of RAM for all of our Zope servers and they work awesome. I would look for something similar. As much as I hate to admit it, I've had better experiences with Intel cpus where servers are concerned. As for Zope on different platforms, we're running 3 Zope servers on RH 7.x and 1 on Windows 2000 Server and we have more problems with the 2000 box than the other 3 combined (it needs to be rebooted frequently). My only argument for 2000 is that data access is REALLY easy using ODBC drivers (that's the only reason that we have the 2000, we have a series of older database servers that we couldn't connect to with linux but had ODBC drivers for).

Re: [Zope] m$ word question
by Dennis Allison 20 Jul '02

20 Jul '02

Greg, If you are running on a MS Windows box and if your Python has the MS Windows extensions, you should be able to invoke M$ Word to do the sort of thing you want. You'll find the Python Programming on Win32 to be indispensible. I suspect there are all sorts of hidden gotchas but, in principle, it should work.
