I'm trying to install said library for use with Python. I tried downloading the executable installer for Windows, which runs, but says it doesn't find a Python installation. Then tried registering (http://effbot.org/zone/python-register.htm) Python, but the script says it can't register (although the keys appear in my register). Then I ...
Hi all, I am reading binary data from one file that specifies intensity values across x and y coordinates (not a open-source image format) and want to convert it to a PNG image (or other widely supported format). I have the data loaded into an array (using the array module) where each element is a integer from 0 to 255. To save this to ...
I have a file which contains a single image of a specific format at a specific offset. I can already get a file-like for the embedded image which supports read(), seek(), and tell(). I want to take advantage of an existing PIL decoder to handle the embedded image, but be able to treat the entire file as an "image file" in its own right. ...
Hi, Given a url to an image is there a way in Django/Python to pull this image in and then display it on my site (resized if possible) Thanks ...
I need to convert series of images drawn as white on black background letters to images where white and black are inverted (as negative). How can I achieve this using PIL? ...
I am getting weird errors when I try to convert a black and white PIL image to a numpy array. An example of the code I am working with is below. if image.mode != '1': image = image.convert('1') #convert to B&W data = np.array(image) #Have also tried np.asarray(image) n_lines = data.shape[0] #number of raster passes ...
Hi I'm using sorl-thumbnail in a Django 1.2 (currently 1.2 RC) project and getting a surprising failure of four of sorl's built-in unit tests. Essentially, the resized images are all 1px shorter than the unit tests expect them to be. See below for details I'm developing on OSX 10.5.8 (not Snow Leopard) with Python 2.5.1 (r251:54863, F...

Hello stackoverflow, I have a python function that takes a string s-expression like "(add (sub 10 5) 5)", where "add" and "sub" are actually image processing functions, and evaluates and creates the image represented in the string. The image processing functions take constants, variables, or other images (represented as lists of vectors...
Where can I find information on what algorithms the PIL ImageFilter functions use? Like how does edge_enhance work? I'm looking to implement a difference of Gaussians filter but if PIL has a filter that works similarly I'll use that. ...
The PIL handbook says ImageMath (containing a function to evaluate expressions) is new in version 1.1.6. Is it now obsolete? It seems like ImageChops has similar functions to perform arithmetic operators on images. ...
I have an image size 400*200. I have a frame size 400* 300. I want to put the image in the center of frame. That is my image cordinate (0,0) starts with the frame cordinates (0,50). ...
I'd like to create a function, like: def generateThumbnail(self, width, height): """ Generates thumbnails for an image """ im = Image.open(self._file) im.thumbnail((width, height), Image.ANTIALIAS) im.save(self._path + str(width) + 'x' + str(height) + '-' + self._filename, "JPEG") Where a fi...

The problem is that the file is not there, apparently it doesnt get uploaded onc...
