I have Orange3.2 installed on Python 3.4 32-bit. I have built a Classification Tree and can view it with the Classification Tree Viewer widget. I want to print the graphical version of the Classification Tree. I've tried to Save the Graph as a .png file as provided for in the widget, and I get a .png file, but with 0 (zero) bytes.
Any suggestions as to how I can print or save this graphical representation of the Classification Tree?
It works for me. Can you try on some small tree first?
Otherwise, try Report. You should get a report which includes the image of the tree (hopefully - if this works). In the Report window, use Save to get an html with embedded image. Open it in browser and save the image.

Hello last_hope_community, ;)
I have tried several options of exporting, the standard export. Works well to SVG.
load patients
figure
tbl = table(LastName,Age,Gender,SelfAssessedHealthStatus,...
Smoker,Weight,Location);
h = heatmap(tbl,'Smoker','SelfAssessedHealthStatus');
saveas(gcf,["test_heatp_save_svg.svg"],'svg') %no export style-> fonts gets embedded
%print(gcf,["test_heatp_print_pdf"],'-dpdf','-bestfit','-r0')
Saveas and print, but here is point 1.
For setprinttemplate one can not adopt the styles from the exportsetup (hgexport and so on). Print has the very nicy opportunity of -bestfit which one can use with print to pdf(with print fonts are embedded automatically) and then to import in Inkscape to use as SVG. But when styles are adopted, by export manually to save it then as SVG within the exportdlg or with saveas, all fonts gets vectorpaths.
Is there a way to apply export styles automatically and then get an SVG File in which the fonts are embedded in SVG like in the upper code?
I have already checked if it is just a heatmap issue but it is not. Same with the following code, without export_style everything is great. But with export style everything gets to vector paths.
figure
plot(1:10000)
title('Hallo')
saveas(gcf,["test_simple_save_svg.svg"],'svg')
%print(gcf,["test_simple_print_pdf"],'-dpdf','-bestfit','-r0')
Best would be if anyone knows a way to apply exportstyles programatically and to then save as svg with embedded font, or apply exportstyles programmatically and then print to pdf with -bestfit,export as pdf would just embed the titles and not the TickLabels.
Additional print with bestfit is not always good because the result from the figure window varies from time to time a lot.
Thanks for help, it's annoying that export as svg makes paths from text that one cannot customize with other programms.
Using iText PDFWrite class we render the inputFile into outputFile. As inputFile has multilayer, due to that the output PDF (outputFile) has outline of its internal layers. Actually PDFWrite merge the pdf layers while rendering it, Here we want to avoid it. We want to render the visible layers/top layers only. We use PDFWrite instead of PDFCopy because we do all matrics operations(move, rotate, scale ..etc) on inputFile.
Files:
Layered Image
Input file
Output file
A bit late but as far as I understand the question, you want to ensure that only visible layers are rendered during processing because your file has some invisible or hidden layers which re-appear. Since iText support will not help you, there is another (free/GPL License) way.
The first step is to 'burn in' the state of the layers and remove the optional content while honoring the visibility state, using another processor. Once that step is done you can continue with whatever version of iText you want.
There are 2 processing options that can 'burn in' the visibility state of Optional Content Groups (= Layers = OCG)
Option 1
Use www.ghostscript.com with -sDEVICE=pdfwrite command line. See GS documentation for full command line
Option 2
Use Poppler's pdftocairo.exe with -pdf command line.
Both will create a PDF that has no interactive layers, with OCG removed. All iText operations will work as normal on that file.
I'm printing some figures in MATLAB in PDF form, and can view them fine with the Evince PDF viewer on Fedora 16.
When I try to include them in LaTeX (TeXLive 2011), however, I get an error
!pdfTeX error: /usr/local/texlive/2011/bin/x86_64-linux/pdflatex (file ./caroti
d_amp_mod_log.pdf): xpdf: reading PDF image failed
However, I can take an example PDF image generated in Mathematica and include it just fine, which tells me that the problem is with the PDF's generated by MATLAB and not with PDF's in general.
Might it have something to do with the set(0,'defaultfigurepaperpositionmode','auto')I put in my startup.m file so that pages would auto-fit the images?
EDIT: I just tried using saveas(figure(1), 'filename.pdf') instead of print(figure(1), 'filename.pdf') and it worked fine, but the PaperPositionMode property is ignored. Any way around this?
Finally found the problem. The correct way to print images is to use the print(handle, '-dformat', 'filename') syntax.
So, for PDF's, we need print(figure(1), '-dpdf', 'myfigure'). See MATLAB documentation on graphics file formats for more information.
Using print(figure(1), 'filename.pdf') still produces a valid PDF for viewing, but it can't be included in LaTeX.
You can try using
pdfpages
or
pgf
to include pdf files. However, you need to use pdflatex only, as you are doing right now.
I am using Perl for automation for report generation. Reports are generated in HTML. same report can be opened in MS word format. tables generated in HTML look good in Word too.
Problem:
Ineed to also insert few graphs in the report. For HTML, I am using SVG::TT::Graph::Line Perl module to generate the graphs.
The idea here is to keep single HTML file that contains all tables and graphs.
Currently every thing looks good in HTML. but when i open the same file in Word, the graphs are replaced by data (because I am using SVG Perl module).
Just wondering what would be the best way to generate graphs for Word file that doesn't change my code much.
Any suggestions with the Perl modules to be used would be much appreciated.
I haven't tried this, but the only thing I can think of is to use ImageMagick to convert the SVG to PNG and then use a Data URI to embed the image in the HTML.
I have a PowerPoint template that contains one slide and on that slide is a chart. I'd like to be able to manipulate that chart's data using .NET.
So far I have code that...
unzips the Powerpoint file.
unzips the embedded excel file (ppt\embeddings\Microsoft_Office_Excel_Worksheet1.xlsx)
It successfully manipulates the data in the excel sheet and zips it back up.
Opens and manipulates ppt\charts\chart1.xml
Powerpoint is then zipped up and delivered to the user
The result of this is a PowerPoint file that shows a blank chart. But when I click on the chart and go to edit data it updates the data and shows the correct chart.
I believe my problem is with the chart1.xml that I am generating. I have compared my generated version with a version created by PowerPoint and they are almost identical. The only differences are in the values for <c:crossAx/> and <c:axId/>.
There are also some rounding differences in the data. But I do not feel like that would result in a blank chart.
Is there another file that I need to edit? Does anyone have any ideas as to what else I should try to get this working?
It's likely a combination the axID value and the rounding issues. The Axis ID, likely, is asking for an integer value and you may be supplying a single/double. So the cached data in chart1.xml doesn't know how to display.
Try your same manipulation that you've been doing, but instead of opening the result in PowerPoint, change the .pptx extention to .zip, unzip and then manually fix the rounding issues to match the original rounding. Then zip back up, change extension back to .pptx and open in PowerPoint. If this fixes the issue of display, you can confirm it is the rounding issue.
Alternatively, and along the same lines. Open your resulting PPTX in PowerPoint as you have been doing, and once you've right-clicked and rehydrated the chart, save as a different file name and compare that with your automated result.
