wand

I wanted to install the Python ImageMagick API wand and followed this site: http://docs.wand-py.org/en/latest/guide/install.html#install-imagemagick-on-windows However, when running a very simple test: from wand.image import Image I get the following output: Traceback (most recent call last): File "F:\PATHTO\Python34\lib\site-packages\wand\api.py", line 137, in libraries = load_library() File "F:\PATHTO\Python34\lib\site-packages\wand\api.py", line 107, in load_library raise IOError('cannot find library; tried paths: ' + repr(tried_paths)) OSError: cannot find library; tried paths: ['F:\PATHTO

If I do the following for root, dirs, files in os.walk(myDir): for myFile in files: with Image(filename=myFile) as img: with Image(image=img) as main: print main.sequence[0].width I end up with memory faults using Wand. I'm sure its the .sequence part. If I remove that, its fine. I've read all I can find on sequence, how its an Image vs SingleImage. The SingleImage sequence part stays in memory. I've tried to use the following: main.sequence[0].destroy() but it does not get rid of the image in the memory. I'm processing thousands of files, but after just a few dozen I get segmentation faults.

I installed Imagemagic (both 32 and 64 bits versions were tried) and then used pip to install wand, I also set the Magick_Home env. variable to imagemagic address but when I run Traceback (most recent call last): File "<stdin>", line 1, in <module> File "c:\Anaconda2\lib\site-packages\wand\image.py", line 20, in <module> from .api import MagickPixelPacket, libc, libmagick, library File "c:\Anaconda2\lib\site-packages\wand\api.py", line 205, in <module> 'Try to install:\n ' + msg) ImportError: MagickWand shared library not found. You probably had not installed ImageMagick library. Try to

The instructions are simple enough in the Wand docs for reading a sequenced image (e.g. animated gif, icon file, etc.): >>> from wand.image import Image >>> with Image(filename='sequence-animation.gif') as image: ... len(image.sequence) ...but I'm not sure how to create one. In Ruby this is easy using RMagick , since you have ImageList s. (see my gist for an example.) I tried creating an Image (as the "container") and instantiating each SingleImage with an image path, but I'm pretty sure that's wrong, especially since the constructor documentation for SingleImage doesn't look for use by the

I have imported wand using the following code from wand.image import Image as WandImage from wand.color import Color with WandImage(filename=source_file, resolution=(RESOLUTION,RESOLUTION)) as img: img.background_color = Color('white') img.format = 'tif' img.alpha_channel = False How can i convert img object to open cv (cv2) image object in python? You would simply write to a byte-array buffer, and pass to cv2.imdecode . from wand.image import Image as WandImage from wand.color import Color import numpy import cv2 RESOLUTION=72 source_file='rose:' img_buffer=None with WandImage(filename=source

I found a so wired thing while converting a pdf to jpeg, so i'd like to figure out that maybe this is a small bug. See the converted jpg below, you could find that, the background color are all black. The image is here: www.shdowin.com/public/02.jpg However, in the source file of pdf, you can see that the background color are normal white. The image is here: www.shdowin.com/public/normal.jpg I thought this maybe my pdf file's fault, however, when i try to use Acrobat.pdf2image in .NET environment, the converted jpg shows correctly. Here is my code: from wand.image import Image from wand.color
