I've installed ctypes and FreeImagePy. When I do this: import FreeImagePy f = FreeImagePy.Image()
I get:
find

I put a 'print self._name' in the ctypes __init__ file, just before
line 296 - it's printing out the 'find' just before the error.
So, in what specific way have I screwed up the install?

What's your ctypes version? Is 0.9.9.6? If yes, can you download the
last svn version, that solve that problem (I hope) and add some
functions? If you can't I'll release a new version (1.2.5) Iain
Bye,

I downloaded and installed 0.9.9.3, and it now works. Thanks!

OK, Ive installed the latest versions I can find, which are FreeImagePy
1.2.4 and ctypes 0.9.9.6, and I'm back to the error I had earlier. Do
you know what's wrong?

Can you download the last svn version from sf.net? Otherwise I'll send
you the last sources privately.

Sorry, I hadn't heard of SVN before, so I didn't know what you were
talking about earlier :). I got the TortoiseSVN client though, and
checked out your newest build, copied it over the top of
site-packages/freeimagepy, updated my ctypes back to 0.9.9.6 (I'd
regressed again), ran my program, and it worked. Thanks!
Next question (and what I'm using FreeImagePy for): I'm loading a pile
of TIF's as thumbnails into a wx list control. I load the image with
FIPY, convert it to PIL, use PIL's antialiasing thumbnail function,
then load it from there into wx. However, when I'm do the
fipy.convertToPil(), it inverts the image? I've inserted a
fipy.invert() before the conversion as a temporary fix, but is there a
reason for this?
relevant code:
def getHeaders(files):
thumbs = []
for f in files:
print "Adding %s" % f
fi = FIPY.Image(f)
fi.setCurrentPage(0)
fi.invert() #temp fix
thumb = fi.convertToPil()
thumb.thumbnail(THUMBNAIL_SIZE, Image.ANTIALIAS)
thumbs.append((os.path.basename(f), pilToBitmap(thumb)))
thumbs.sort()
return thumbs
Iain
p.s. thanks again

Why use PIL for it and not FIPY directly? You can use the image.size or
the other methods for resize the image
However, when I'm do the fipy.convertToPil(), it inverts the image?
No, it not invert the image... It only return the image as is.

If you are have a min-is-white image (fax ?) that isn't the standard,
you will have an "inverted" image, because PIl expect a min-is-black
image!
relevant code:
def getHeaders(files): thumbs = [] for f in files: print "Adding %s" % f fi = FIPY.Image(f) fi.setCurrentPage(0) fi.invert() #temp fix thumb = fi.convertToPil() thumb.thumbnail(THUMBNAIL_SIZE, Image.ANTIALIAS) thumbs.append((os.path.basename(f), pilToBitmap(thumb))) thumbs.sort() return thumbs
Just a question, why "thumbs.sort" ? Inside this list you have only
images!
P.s. you can use also fi.currentPage = 0 rather then
fi.setCurrentPage(0). Is think it look like better :) Iain
p.s. thanks again
:)

This is probably what is happening. I'll upload one of the images
tomorrow, and you can check it out to make sure. relevant code:
def getHeaders(files): thumbs = [] for f in files: print "Adding %s" % f fi = FIPY.Image(f) fi.setCurrentPage(0) fi.invert() #temp fix thumb = fi.convertToPil() thumb.thumbnail(THUMBNAIL_SIZE, Image.ANTIALIAS) thumbs.append((os.path.basename(f), pilToBitmap(thumb))) thumbs.sort() return thumbs

Ah, look closer! It's a list of tuples: (filename, image)
I'll try out FIPY's resizing tomorrow too. OTOH, I have functions to
convert between PIL and wxPython, and functions to convert betweem PIL
and FIPY, but I don't see a function to convert FIPY to wxPython?

Yes it's min-is-white::
michele:~$ tiffinfo example.tif

So you *need* to invert it to work correctly with PIL!
P.s. Added the convertToWx function, that return a wx.Image, to the
Image class.

PIL has no problem reading "min-is-white" TIFF images.
it would be nice if you stopped posting bogus "support" information for
other libraries.

Sorry if my posts make to seem that other libraries has problems! Sure
that *my* wrap has problems, like I have problem with something that I
don't know so well, like Image world (like I always said). I'm only
suggesting some, bad, trick for do the work that "Iain" wants.
I tried, but without success, to make the "convertToPil" function work
with 1, 8, 16 bpp... Seem that only 24/32 work, but I don't know why.
I know that PIL doesn't have problems! </F>
Hope that this can explain better the situation.
