Subject: [Image-SIG] display of PIL image with a palette
Message-ID: <38EA5500.C2BC7C95@grc.nasa.gov>

Hello,

Does anyone know how to display a paletted PIL image in wxPython? The
PIL image mode is "P".

I'm attempting to pseudocolor an 8-bit grayscale image by applying an
RGB palette (256 RGB values). The program seems to be displaying the new
image.

present or not, it seems PIL isn't able
import it.

try importing _imaging by hand, and see
what happens.

Does any one work with VTK or Tkinter that can help render some images?


What I need to do is render some images that I have already created using

Message-ID: <38EB91DC.90915E74@grc.nasa.gov>

Yesterday I posted a message asking if anybody knows how to display a
PIL image of type "P" (with a palette) using wxPython. I've got no
replys but I got it working another way - producing a 24-bit pseudocolor
image as output. For anyone interested here it is:

Convert the 8-bit image to 24-bit image (img = im.convert("RGB")). Then
just call the point function as (out = img.point(palette)) where palette
is a list of 256 red, 256 green, and 256 blue values. out is a 24-bit
color (pseudocolor) image which can now be displayed in wxPython (after
a conversion using SetData)

make sure _imaging.dll (or _imaging.pyd, depending on the
distribution) is installed in a directory along the python path.

if you don't really care where it's installed, just place it in the
same directory as the python executable.

On the other hand too, if you've installed the Win32 extensions for Python
(see www.python.org), I have an installer that will automatically set
everything up for you.

It's available at:

http://members.home.com/lenticular


It's a self-extracting script that runs a Python setup file.

afaik, you're the first one trying PIL with both Tk 8.3.0 and
the new object-based Tk interface in 1.6a.  I'm afraid I don't
have the slightest idea if the problem is in PIL, Tk 8.3, or the
new Tk interface...

you could try downgrading _tkinter.c only, and see if that
helps (check the logs to see which version to use; the object
changes was made a few weeks ago).

...

speaking of 1.6, note that there are a few broken "append"
calls in PIL 1.0, including these (as reported by checkappend):

.\PIL\JpegImagePlugin.py(90):
        self.layer.append(t[0], ord(t[1])/16, ord(t[1])&15, ord(t[2]))

.\PIL\PcfFontFile.py(129):
            p.append(i32(fp.read(4)), ord(fp.read(1)), i32(fp.read(4)))

.\PIL\TiffImagePlugin.py(213):
            l.append(self.i32(data, i), self.i32(data, i+4))

.\PIL\TiffImagePlugin.py(491):
                self.tile.append(

.\PIL\TiffImagePlugin.py(510):
                self.tile.append(

adding extra () around the append arguments will fix this.

Another followup: never change 2 things at a time. It does work if I
use dynamically linked Tcl/Tk libraries, and recompile everything from
scratch. This approach is much better anyway; otherwise I'm using 2
copies of the tcl/tk libraries: one linked into _tkinter and the other
into tkimaging. I just have to add a library to my LD_LIBRARY_PATH
now.

Sorry for the vague reports.

Message-ID: <38F616B3.F89F231E@fleetingimage.com>

A quick deja search of "PIL libtiff" reveals that
in comp.lang.python on 1998/08/27, Fredrik mentioned:

  "We're working on an (optional) libtiff plugin for PIL,
  but there's no set date when that will be available."

Has any further work gone into this? My use of PIL has been severely
limited by its inability to handle RGBA tiff files.
(I can convert to png, or split them into four single channel images
prior to import, but this is messy.)

Also, has any thought been given to supporting 16-bpp data?
I currently filter my data into Numeric but would love
to have the best of both worlds.

Message-ID: <s8f5f21b.076@cymbolic.com>

If you're only need is RGBA, you can do a VERY quick mod of TiffImagePlugin.py that
will allow them to work properly, as follows (Fred helped me with the same issue a
while back):


# TiffImagePlugin.py
# line 101
# change     (2, 1, (8,8,8,8), (0,)): ("RGBX", "RGBX"),
#to:
    (2, 1, (8,8,8,8), (0,)): ("RGBA", "RGBA"),

A quick deja search of "PIL libtiff" reveals that
in comp.lang.python on 1998/08/27, Fredrik mentioned:

  "We're working on an (optional) libtiff plugin for PIL,
  but there's no set date when that will be available."

Has any further work gone into this? My use of PIL has been severely
limited by its inability to handle RGBA tiff files.
(I can convert to png, or split them into four single channel images
prior to import, but this is messy.)

Also, has any thought been given to supporting 16-bpp data?
I currently filter my data into Numeric but would love
to have the best of both worlds.

try creating the label widget before you create

yes, but the above statement still applies...

are you using PhotoShop, and PIL opens the files as "RGBX"?
if so, it's photoshop's inability to generate valid RGBA files,
not PIL's inability to read them... ;-)

see kevin's mail for a workaround.

PIL has (undocumented, experimental, and rather limited) support for
16 bit images (see the CHANGES file for details).

there are patches out there that adds more extensive support.
searching the image-sig archives may help you find them.

The script to convert BDF files to PIL format is available in the standard
distribution (PilFont.py).  I modified it a bit to automate it for my
purposes though.  The 'real' trick was getting all my fonts into BDF format
first.

To do that, I purchased a program called "FonMaker" that converts Windows
fonts (Type 1 and TT) to BDF.  It's $99 USD, available at
http://www.fontlab.com.  I have a HUGE library of Windows fonts, but
converting them will just take too much space.

Ok.  Makes sense.

You know I was thinking last night.  XFree86 (the X distribution that's
provided with FreeBSD, Linux, etc.) now provides true-type-capable X
servers that'll use TrueType font files directly.  

With these X servers, you can use TTFs just as you can conventional X
fonts.  For example, I use the Verdana TTF in Netscape under FreeBSD for
web browsing.

Since with X you can render fonts into off-screen pixmaps, I wonder if
anyone has built (or has thought of building) a Python-/PIL- back-end to
interface with the standard X font API?

...or maybe this is already supported.  (I'm just now starting to use PIL,
so I don't know.)

Thanks again for the TTF conversions, Kevin.

Actually, a week or two ago, Joerg Baumann posted a patch for PIL that
allowed you to use the FreeType2 engine to render fonts into PIL format
on-the-fly.  This, I see as the perfect solution, once FreeType2 is
buildable on all major platforms.

Fred:  is there any problem building that patch into PIL, with whatever
modifications necessary to allow you to load the FreeType2 library from a
configurable directory (or maybe just somewhere on the system path or
PythonPath?

Currently, that library is only supported on Linux, although I havent tried
building it myself.

Message-ID: <v03130301b523ad72b795@[128.15.32.195]>

I'm intend to use PIL to view and manipulate images. My question is how to
use 2D FFT techniques on the image objects created by, e.g. im =
Image.open("imagefile.psd") ??

It would be very convenient to use the FFT routines implemented in the
Numeric package.  I expect I'd have to create a 2D 'array' object from
'im', unless by great good fortune the Numeric package is already familiar
with Image objects (unlikely I'd guess).  That suggests I'd need to extract
the data from the image object.

Any good suggestions on how to proceed here?  If anyone has a different way
to accomplish this I'd be very interested.

Thanks for your help.

Jeff,

I don't know for sure since I've never done it but from what I know of
Numeric Python (NumPy), it should be fairly easy. Since I doubt that
NumPy understands PIL image format, you'll have to convert the image to
a linear array of integers and then read it into NumPy. To convert PIL
image to a list of integers, do:

d = img.getdata()

and then read "d" into NumPy using array call. Convert it to a 2-d
array. For color images you'll probably have to split the image into
r,g,b planes first.

I think it is a better idea to use im.tostring() and the Numpy
fromstring() routines. Twhere is currently no direct connection between
the two packages.

Les Schaffer sent me some code which does a data transfer to and from PIL
data structures using the tostring / fromstring functions. It works very
well and I'm playing with it now. Transfer to Numeric is easy from that
point.

I was not aware previous to this that PIL is internally oriented around 8
bit pixel values.  I'm interested in working with 12 bit grayscale scanned
images at very high resolution.  For the moment my scans are still at the 8
bit level so I can use the present implementations, but I wonder about how
to proceed once I have the higher bit depth.  Adobe Photoshop has very
limited capability at greater than 8 bit depth, so PIL looked like a good
path - especially since I have numeric processing in mind.  Does anyone
have a solution to this?

Thanks everyone for the useful suggestions!  This SIG is a very good
resource for beginning / occasional users.
