Geting information about images

I have a quick question which will probably lead to a long answer. I would like to find a way for python to examine a .jpeg or .gif file and return the image dimensions in pixels. I've been looking through the img* files but I can't find anything so simple. Thanks for any help, Josh English english(a)spiritone.com

To the credit of Apple, it is only recently, and far after the freeze of Jaguar, than it became obvious (at least to me) that MacPython was going to default to the framework layout. But that raises an interesting question of how to deal with Apple (or Apple with Python) as far as packaging is concerned. Is now python part of the Darwin project ? Did someone see a python folder popping up in the CVS folders of Darwin ? If that is the case, a simple patch that tweaks the Darwin makefile for Python might be enough, and we just have to suggest it. If not, we need to find out who is in charge at Apple.

Apple hadn't shipped Python with the system to this point in time because Python was too much in flux during the period of time that Apple was in the process of freezing the system. Bummer that they didn't stick with one version behind, but considering that Fink has always provided the latest stable version of python via a simple command (fink install python), it was not a big deal and, likely, caused less hell than shipping a version of python one major version behind the rest of the world. In terms of the Python-as-a-framework build, it was wwwwaaayyyy in flux in the middle of when Jaguar was frozen many months ago. Keep in mind that Jaguar and Darwin are frozen *months* before release. On the above-darwin layers, this means that changes may still happen to fix bugs, etc. On the below darwin layers, it means that whatever version of the various random utilities-- curl, perl, python, ruby, etc... -- are frozen until after the system ships. A python folder *should* be in Darwin somewhere -- I haven't looked. It is clearly a *relatively* default build, though it seems to be missing a .a, as well. However, there is no conflict with simply doing 'fink install python' to provide a library. If anything, someone should put together a Fink package that installs python as a framework. This makes it extremely accessible and also gives the Apple folks an easy way to grab and install the package or -- at the least -- see the patches necessary to make the build happen. However, for Apple to release Python as a framework requires significant effort above and beyond simply providing a buildable source tree. They have to verify that it doesn't conflict with other parts of the system -- sounds trivial, but isn't entirely so because it also requires that building the Python based framework install can be totally quantified and totally automated (i.e. what if a security hole is discovered and Apple has to release a .pkg that includes just Python?). If you have simple tweaks for the makefile, please ensure that a Fink package is created and also file a bugreport.apple.com based feature request that includes both a request for the framework build of Python AND the instructions on how to do so! I would *love* to see Python.framework as a standard part of the system -- it will take time. And while you are at it, make sure you pick up the PyObjC module. Ronald has done an ABSOLUTELY INCREDIBLY FREAKIN' AMAZING job of pushing the project forward to the point where you can build Real World Cocoa applications using Python -- including using Python to subclass ObjC classes.

Is anyone else seeing this? I noticed that test_pep263.py has changed recently (36 hours ago), but I'm crashing before hitting the change. -- bill

Requesting a port?
by Robin Siebler Sept. 10, 2002

Sept. 10, 2002

How do you request to get something ported to the Mac (assuming that the author of the program doesn't have a Mac)? I just stumbled across a Midnight Command clone that is written in Python. When I try to run it on the Mac, I get the following error: 'Bus Error'. I don't know what this means, but I assume this is some Mac specific problem. The program is called lfm and can be found here: http://www.terra.es/personal7/inigoserna/lfm Robin L.

Fast way to get a list of unique values?
by Robb Brown Sept. 10, 2002

Sept. 10, 2002

I have a large array (Numeric) of integers. I'd like to get a list of all the unique values in that array. Naturally I'd like to avoid a for loop. Is there an easy way to do this in Python? Thanks, Robb -- ______________________________ Robb Brown Seaman Family MR Research Centre Calgary, Alberta, Canada

Framework install
by Matthew Smith Sept. 10, 2002

Sept. 10, 2002

Hello, I'm having a bit of trouble with the 2.2.1 python framework install, I downloaded the latest source, then typed: ./configure --enable-framework sudo make install The problem is that the framework that is installed at /Library/Frameworks does not have the header alias at all, and the framework that was created in the download directory does has a blank alias (cannot be found) as the one that shopuld point to the header files... Any idea what could cause this, and how I could fix it??? Thanks for the help, Matt Smith

So it probably wouldn't be that difficult, at least for MachO support.... But Build Application is roughly comparable... I'm not sure what would be gained.... (I use Installer on the PC, and BuildApplication on the Mac) Can anyone explain where the defects are in BuildApplication, that we need to investigate a different route? - Benjamin

One large, major comment.... But first, a disclaimer.... I haven't been following this tooo closely... XML is not a database system.... Please don't try to force XML to do a job it has not been designed to fill... Yes it can be used as a "flat" database, but that is probably not going to be suitable (long term).... Instead use Mysql, or some other true database program.... Allow XML to be used for submissions, or for "description files", or whatever... But allow a database program to handle the actual database searches... If we do use a flat database design, based off of XML, then create some form of external indexes to reduce the amount of time we have to parse the XML.... Or possible shelve the XML data.... After every modification, just shelve it to a file, and when it's accessed just load it back in from the shelve.... (I've seen flat database systems that have completely outgrown there capacity....) - Benjamin
