From bill@janssen.org Thu Feb 1 04:24:48 2001 From: bill@janssen.org (Bill Janssen) Date: Wed, 31 Jan 2001 20:24:48 PST Subject: [Image-SIG] Palm extensions for PIL available Message-ID: <01Jan31.202456pst."3448"@watson.parc.xerox.com> Fredrik, I've completed some work on extending PIL 1.1.1 to support raw Palm image quantization and output. You can find a gzipped tar file containing a patch and a new ImagePlugin at ftp://ftp.parc.xerox.com/transient/janssen/PILpalm.tgz. The README in that file explains how to apply the support to a vanilla PIL 1.1.1 source distribution. The most interesting thing to you, I think, is the extension of the quantize method, via a new keyword, to support quantizing the colors of an image to a specified palette. That palette is specified by passing an image containing the desired palette. There were a number of ways to add this functionality; this seemed to be the approach that involved the minimal change to PIL. If you'd like to discuss any philosophical or technical issues about how I've done this, I'd be happy to do so. I'd appreciate it if this got into the next release of PIL; of course your release schedule is your own.

I'll quite happily pick it up again once those problems are solved, but I need a imaging library very shortly. I'm trying to get python talkingwith ImageMagick, but cant seem to get the swig interface working properly. Eg: What is this 'Imaging.h' header? Has anyone out there successfully employed python and ImageMagick? If so, I'm more than happy to put the effort into getting a module running that anyone can use.

How do you create transparent images in PIL? I'm hoping for IE-happy PNGs, but can live with GIFs. Here is the method I'm trying now (I've tried several, but this one was reccomended in another archive entry) >>> import Image >>> img = Image.new("RGB",(100,100),(0,100,200)) >>> img = img.convert("RGBA") >>> img.paste((100,0,200,255),(0,0,100,100)) >>> img.paste((0,0,0,0),(20,20,80,80)) >>> img.save("region-13.png") The 'transparent' sections come up gray in IE. I wonder if the real problem is on the PIL side or the client side. Either way, I need PIL to satisfy the client, no matter how broken the client may be. Also, simply opening a transparent GIF, Drawing on it and saving it results in seemingly random colors placed in the transparent space. Does PIL support transparent images? Can someone provide a tested example? Platform: RH6.2, python 2.0, PIL 1.1.1 (Win32 will also be a target eventually) Thanks in advance, - Scott From echuck@mindspring.com Thu Feb 8 15:23:02 2001 From: echuck@mindspring.com (Chuck Esterbrook) Date: Thu, 08 Feb 2001 10:23:02 -0500 Subject: [Image-SIG] Help with ImageMagick-Python In-Reply-To: Message-ID: <5.0.2.1.0.20010208102215.027e4600@mail.mindspring.com> At 12:08 AM 2/8/2001 -0800, Chris Cogdon wrote: >Has anyone out there successfully employed python and ImageMagick?

For every product I use, I develop an impression, good or bad. Echoing someone else's impression of product X and desire to use product Y is not a whine.

To me PIL is the only contender I can consider, because it has more features than any of its competitors, and because it's not too difficult to write C extensions that create new Image objects (even though this is documented, it wasn't hard to figure out from the source). That's why I wrote the SANE and PXC-200 modules, which are PIL add-ons of a sort; nothing comparable seemed to be possible with other packages such as the gd module. Fredrik, you're busy with other things such as PythonWorks. Is PIL development still a source of revenue for you?

I haven't done anything with any image processing for the past few weeks, whether it's trying work-arounds or other packages. FYI, my other PIL problems are: * Lack of file support. Eventually I'll get to posting the test suite that I was given by a graphic designer. * And if I remember right: I couldn't save a GIF to JPEG. Something about the palette not being right. I was hoping PIL would do the "right thing". There may be a work around for that.

Under Windows, Python sets the path based on the location of the Python core DLL, information from the registry, and the PYTHONPATH environment variable. Quick workaround 1: figure out where the standard PYDs/DLLs are: >>> import _socket >>> _socket.__file__ 'c:\\py20\\dlls\\_socket.pyd' and put the _imaging.dll in the same directory. (if the _socket import gives you an import error, your installation is broken. consider reinstalling...) Quick workaround 2: move the _imaging.dll to the same directory as PIL's python library files (e.g. c:\python20\PIL).

What do they do and where can I find them? They're for grabbing data from an output device and returning a bitmap as a PIL object. A PXC-200 is a frame grabber, and SANE is a library supporting various scanners, and, most interesting for our purposes, the Polaroid Digital Microscope Camera. It's actually pretty impressive; using PIL and the PXC-200, a server program written in Python can continuously grab frames from a microscope, JPEG-compress them, and send them out at the rate of 21 frames/sec, which isn't too far off the 24 or 30 frames/sec that would be ideal. (The problem is that Java seems to take .4 sec to *de*compress a JPEG, so our Java client is completely incapable of keeping up with a Python server running at the rate. We have a Python/Tkinter client, only used for demos, that can keep up with that speed. So much for Java being "almost as fast as C++".) --amk From klimek@grc.nasa.gov Thu Feb 8 22:35:09 2001 From: klimek@grc.nasa.gov (Bob Klimek) Date: Thu, 08 Feb 2001 17:35:09 -0500 Subject: [Image-SIG] SANE and PXC-200 modules Message-ID: <4.2.2.20010208171034.022e6df0@parrot.grc.nasa.gov> Thanks to both of you (Andrew and Fredrik) for your replys.

I had contemplated creating a Python class that does os.system() *if* ImageMagick has less issues than PIL (more file format support, better resizing, save GIF to JPEG with no hassles). >I might go back to PIL and fix it up.

I've yet to hear >a reply to that one. Sounds interesting. That's a heck of a test suite. :-) I also investigated PyGIMP, but I found it a lot harder to get going than PIL. I couldn't even launch GIMP in command-line only mode. Well if you have any more updates, please pass them on.

The problem is that no matter how hard I try, the output in ofile (which should be RGBA) is always RGB. I've looked through the code for the PngImagePlugin at http://w1.132.telia.com/~u13208596/pil/PngImagePlugin.py which I am using and it appears to support RGBA output. The debug code outputs the channels of the final image and the sourced alpha channel. All of these PNG files look fine (they are all greyscale obviously). The final ofile PNG is RGB and has no color channels. I'm not really familar with PNG, but it appears to be the only format that writable format that is supported by PIL and supports RGBA, so I seem to be screwed. Can anybody explain why this is happening?

About a year ago I played around with JAI (Java Imaging), before giving up on Java and switching to Python. And my experience with JAI was that it was a major pain in the butt. In comparison, PIL is a pleasure to work with. So anyone who wants to improve PIL, I think its great. Bob --------------------------------------------- Robert B.

If you look into GifImagePlugin.py in the PIL directory, you'll find comments telling you which lines to change. It really is easy, if you have netpbm installed. You can also adapt the function there to make transparent gifs, code for which I posted a wee while ago. I'm not sure how possible it is to write new code that properly compresses gifs, given the unco-operative stance that Unisys has over its patents.

[PIL] Message-ID: <4.3.2.7.2.20010220075743.028fb7b8@pop.fas.harvard.edu> Hello:

I have a question about PIL's Image.getdata() method. The manual states:

getdata(). Returns the contents of a the image as a sequence object containing pixel values. The sequence object is flattened, so that values for line one follows directly after the values for line zero, and so on.

But when I tested this this does not seem to be the case. My test image is a TIFF file with a simple black line (value = 0) on a white background (255). The code below doesn't return the correct data array. The zeros are all in the wrong places, and from their jumbled pattern it doesn't seem to be a simple swapping of the axes.

        im = Image.open('test.tif')
        size = im.size
        data = im.getdata()
        flatarray = array(flatdata)
        return reshape(flatarray, size)

Im.show() works just fine however. It's late, so I'm hoping that I'm not missing the obvious, but isn't this how getdata() should work?

Would appreciate some help. thanks,

(in the current code base, line 405 should most definitely use palette.mode, not palette.rawmode. same goes for the use of palette.mode in the convert function. maybe the bug is else- where?)

According to the documentation, this should pick a mode "so that all information in the image and the palette can be represented without a palette." According to the 1.1 code, this doesn't work. Use convert("RGB") instead.
