I'm trying to figure out how to add line spacing without adding spacing above the very first line of textflow.
This code:
$text = 'For more information about the Giant Wing Paper Plane see ' .
'our Web site <underline=true>www.kraxi-systems.com' .
'the Giant Wing in a thunderstorm as soon as possible.';
$optlist = 'fontname=Helvetica fontsize=12 encoding=unicode leading=400%';
$tf = $p->create_textflow($text, $optlist);
$result = $p->fit_textflow($tf, 28.346, 28.346, 400, 700, 'fitmethod=nofit');
$p->delete_textflow($tf);
results in:
All is good.
Next, I'm increasing the leading option to 400% as:
$optlist = 'fontname=Helvetica fontsize=12 encoding=unicode leading=400%';
And that gives me this:
Question:
How do I keep first paragraph line at the original position and only increase line spacing AFTER it?
checkout the "firstlinedist" option. The default is leading, but you might set this to "ascender" or "capheigt" or any other value.
Please see PDFlib 9.2 API reference, chapter 5.2, table 5.12 for more details.

I'm attempting to perform diffeomorphic demon registration of two MRI images. The processing pipeline has been this so far:
Skull-stripping
Anisotropic Diffusion (smoothing)
Histogram Matching
Affine registration
Diffeomorphic Demons Registration
I didn't come up with the process, just fixing and cleaning up a Slicer software tool several researchers have built. I'm a summer student and quite unfamiliar with domain, however I've started to more less understand what's going on. The problem I've been unable to solve for the past several weeks is this error:

From what I understand, the diffeomorphic registration relies on the two images being coincident, hence the affine registration step beforehand. For some reason though, the affine transformation doesn't line up the two images properly. As a result, they don't occupy the same physical space. I'm clearly missing something but can't seem to figure out what it is.
The affine registration is performed with this file (I made some edits on my local copy to comply with the Slicer module's way of input/output but they're nearly identical). The transform that was created had the following characteristics:
Optimizer stop condition: RegularStepGradientDescentOptimizerv4: Step too small after 33 iterations. Current step (9.76563e-05) is less than minimum step (0.0001).

Center Y = 11.6381

Iterations = 34
Metric value = 8974.52
Scale 1 = 1.15384

The following code was used to save the transform to a file:
// Write the transform to a file
itk::TransformFileWriter::Pointer transformWriter = itk::TransformFileWriter::New();
transformWriter->SetInput( registration->GetOutput()->Get() );
transformWriter->SetFileName( outputMatrix.c_str() );
transformWriter->Update();
And the demon registration is performed with this file (Made a few edits but mostly the same as well). The affine transform is loaded at line 799.

It looks like the Diffeomorphic Demons Registration code you are using requires that Fixed and Moving images have the same physical space, meaning:
Origin
Spacing
Dimensions
Did you try to resample your moving image to the fixed image space, and then call the Diffeomorphic Demons Registration with this resampled moving image and fixed image?
I didn't know this EZminc code but it looks like it requires both inputs to be in the same space somehow.
Hello I am currently using Python 3, BeautifulSoup 4 and, requests to scrape some information from supremenewyork.com UK. I have implemented a proxy script (that I know works) into the script. The only problem is that this website does not like programs to scrape this information automatically and so they have decided to scramble this script which I think makes it unusable as text.
My question: is there a way to get the text without using the .text thing and/or is there a way to get the script to read the text? and when it sees a special character like # to skip over it or to read the text when it sees & skip until it sees ;?
because basically how this website scrambles the text is by doing this. Here is an example, the text shown when you inspect element is:
supremetshirt
Which is supposed to say "supreme t-shirt" and so on (you get the idea, they don't use letters to scramble only numbers and special keys)
this is kind of highlighted in a box automatically when you inspect the element using a VPN on the UK supreme website, and is different than the text (which isn't highlighted at all). And whenever I run my script without the proxy code onto my local supremenewyork.com, It works fine (but only because of the code, not being scrambled on my local website and I want to pull this info from the UK website) any ideas? here is my code:
import requests
from bs4 import BeautifulSoup
categorys = ['jackets', 'shirts', 'tops_sweaters', 'sweatshirts', 'pants', 'shorts', 't-shirts', 'hats', 'bags', 'accessories', 'shoes', 'skate']
catNumb = 0
#use new proxy every so often for testing (will add something that pulls proxys and usses them for you.
UK_Proxy1 = '51.143.153.167:80'
proxies = {
'http': 'http://' + UK_Proxy1 + '',
'https': 'https://' + UK_Proxy1 + '',
}
for cat in categorys:
catStr = str(categorys[catNumb])
cUrl = 'http://www.supremenewyork.com/shop/all/' + catStr
proxy_script = requests.get(cUrl, proxies=proxies).text
bSoup = BeautifulSoup(proxy_script, 'lxml')
print('\n*******************"'+ catStr.upper() + '"*******************\n')
catNumb += 1
for item in bSoup.find_all('div', class_='inner-article'):
url = item.a['href']
alt = item.find('img')['alt']
req = requests.get('http://www.supremenewyork.com' + url)
item_soup = BeautifulSoup(req.text, 'lxml')
name = item_soup.find('h1', itemprop='name').text
#name = item_soup.find('h1', itemprop='name')
style = item_soup.find('p', itemprop='model').text
#style = item_soup.find('p', itemprop='model')
print (alt +(' --- ')+ name +(' --- ')+ style)
#print(alt)
#print(str(name))
#print (str(style))
When I run this script I get this error:
name = item_soup.find('h1', itemprop='name').text
AttributeError: 'NoneType' object has no attribute 'text'
And so what I did was I un-hash-tagged the stuff that is hash-tagged above, and hash-tagged the other stuff that is similar but different, and I get some kind of str error and so I tried the print(str(name)). I am able to print the alt fine (with every script, the alt is not scrambled), but when it comes to printing the name and style all it prints is a None under every alt code is printed.
I have been working on fixing this for days and have come up with no solutions. can anyone help me solve this?
I have solved my own answer using this solution:
thetable = soup5.find('div', class_='turbolink_scroller')
items = thetable.find_all('div', class_='inner-article')
for item in items:
alt = item.find('img')['alt']
name = item.h1.a.text
color = item.p.a.text
print(alt,' --- ', name, ' --- ',color)
Really simple (in theory): is there a way to insert line breaks in google forms questions? Here's what I'm looking at:
form.addScaleItem()
.setTitle('Question?')
.setHelpText('(1 = Poor 2 = Poorer')
.setBounds(1, 7)
.setLabels(lower= 'lower label line 1, lower label line 2',upper= 'upper label')
.setRequired(false);
Ideally, I'd like to be able to put line breaks in the setHelpText and/or setLabels, but the usual html <>'s (br, /br, br/, p, etc.) don't work. Thoughts or workarounds?
You can do it by using standard js line break "\n":
var item; // = ...
item.setTitle("To be?\nOr not to be?");
My problem is that in Chrome, when I have my cursor on my histogram hover my data, I have this error :
Uncaught TypeError: Cannot read property '0'
There is my code :
hist, edges = np.histogram(data,bins=3000)
plot = quad(
top=hist,
bottom=0,
left=edges[:-1],
right=edges[1:],
fill_color="#036564",
line_color="#033649",
tools="pan,wheel_zoom,box_zoom,reset, hover",
x_range=[-0.5,3.5],
plot_width=1100,
title="",
)
hover = plot.select(dict(type=HoverTool))
hover.tooltips = [('index','$index')]
resources = Resources("inline")
plot_script, plot_div = components(plot, resources)
html_script = mark_safe(encode_utf8(plot_script))
html_div = mark_safe(encode_utf8(plot_div))
figure()
return html_script, html_div
"data" is a array like this :
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1.24,1,1.32,1,2,3]
I tried to add a "source" in the quad, changed the figure, changed my code for the one on the documentation but I still have my error.
For information, everything is working very well, except the hover tool.
Indeed, in the "hover box" I want another informations then just "index", but it's just for testing.
Thanks for reading !
Sorry I missed this earlier. You have uncovered a small bug with the hover tool that is particular to quad glyphs. In the mean time you can add hover.snap_to_data = False to get it to work.
Here is a GH issue you can track for the full solution:
https://github.com/bokeh/bokeh/issues/1644
A fix should be in the 0.7.1 release next Monday.
Also BTW, you are using a deprecated API. You should now write code like:
p = figure(...)
p.quad(...)
I'd like to print a plot with y-error-bars and just plain points. My current Octave script looks like this:
errorbar(x_list, y_list, Delta_y_list, "~.x");
title("physikalisches Pendel");
xlabel("a^2 [m^2]");
ylabel("aT^2 [ms^2]");
print -dpdf plot.pdf
The plot I get has a line, although I specified the .x style option:
http://wstaw.org/m/2012/04/14/umbrella5.png
How can I get rid of that line?
And the ylabel is in the scale as well, is there some way to fix that?
One has to set the linestyle:
p1 = errorbar(plot_x, plot_y, plot_error, "~.k");
set(p1, "linestyle", "none");
set(p1, "marker", "+");
