I am working with different plots created using the script running in octave. Earlier i used irfanview to view all the plots. But somehow now Irfanview can't output the quality so i am turning to GS view as it can handle vectors better. The problem i am facing is that i cannot just scroll through all the plots in one folder in Gs view as i used to do in Irfanview. I have to drag and drop each file to open the plot. Is there a way that i can simply scroll through files in GS view. All the plots are in same folder.

I used this code to display multiple images in the same namedWindow. Now I want to display some of the calculation results (that I have calculated before with image processing functions).
The results should be displayed in the fourth position of the namedWindow, like I show in the red square in the image below:
Is there any way in opencv that can throw console window in the namedWindow? Can I copy the results from console window in any other way on the named window? Is it possible to create somehow scrolling window with all information and put them on ?
I would suggest creating an new Mat with either ones() or zeros() and then using the function putText to insert your text.
Afterwards show the Mat like the rest before
I'm currently looking for a way to create a 'configurator' for a upholsters, similar to http://digitaldraping.com/configurator/furniture-sofa/?Cushions_Plain-Cream.png,Sofa_Stripe-Orange.png - you select your fabrics and they are 'drawn' on the sofa automatically.
Unfortunately, all the sites I've looked at seem to use pre-rendered transparent PNGs that are overlaid over each other to build up the full picture. The problem here is that we've figured out that we'd require over 120,000 different images to cover all models, fabrics etc!!
I've looked at a few 3d texture tools such as http://www.arahne.si/products/arah-drape.html, hoping that one of them would have a CLI option where you give it a pre-created wireframe, and a fabric to overlay, and it generates the required image on the fly, but so far everything seems to require real-time use of the GUI to use it.
So, is there a CLI tool that would do what I'm after, or can anyone suggest a way to manipulate the GUI automatically? (from a tech point of view, I'm comfortable with C, Bash, Python or PHP as a solution!)
Thanks!
ArahDrape 2.2 can now work from a command line without any GUI interface. You can also call ArahDrape as a C library. In this way, it can be used in a web server to create texture mapped images on the fly. The command line options are explained below.
ArahDrape 2.2j command line version, ©2015 Arahne
usage:
adCommand -o /tmp/outputImage.png -tN /home/user/texture.png [-hidemodel] [-divide 2] [-filterPNG] [-compressPNG 2] [-m /home/user/model.png] -owner name -activation 174b3cfb49e9 /home/user/project.drape
Input and output images can have png, .tif or .jpg extensions
-o output_image_file
-tN texture_image_file [N goes from 0 to 199]
-hidemodel will render all areas not in region as white
-divide N [N goes from 2 to 5] divide resulting image pixel size
-filterPNG if you do not filter it, rendering is faster
-compressPNG N [N goes from 0 to 9] lower number saves faster, but bigger files
-m model_image_file use this if you want to replace model image from the project; must have same pixel size
-owner owner_name pass the given owner name
-activation activation_code pass the given activation code
last parameter should be ArahDrape project file
All files should be entered with full path.
If you need spaces in filenames, use quotes "" around the filename.
If you provide only Owner name, without activation code, program returns registration code.
ArahDrape supports batch export.
Open ArahDrape project, click on texture you wish to replace, put all your texture in a directory, select from menu
Textures > Browse textures, and as you click the texture to load it, program will save the draped picture. If you have thousands of images, use keyboard shortcut = and program will automatically do them all.
Alpha channel transparency is supported in loading model images or textures, and saving the draped images, as long as you use PNG or TIFF.
Please check this video to see how
ArahDrape works in batch mode.
we (http://digitaldraping.com/) can do just what you are asking. We have two options creating images and rendering a meshed image on the fly. Just get in touch if you still need this solution.
I am creating D3.js animations, like this: Demo
Let's say I want to present my work here (or on a blog). About the best I can do is post a picture:
On the other hand, if I, let's say, use the Python library Matplotlib for data visualization, I could produce an animated GIF file, and post it here:
I would like to programatically obtain similar animated GIF files out of my D3.js animations. How can I do this?
NOTE: I started working on getting events from d3.transition(), but so far I didn't have any luck.
The solution uses a tool called LICEcap, a screen capture utility for Windows and Mac. Steps are following:
Download LICEcap and install it. Now, if you start this program, it will have a rather unusual shape, just a thin frame, and everything inside the frame will be transparent:
Go to the window with your D3.js animation and prepare everything so that you could start animation at some point. Let's say we want to record this example from d3js.org:
Now start LICEcap and position it over the area you want to have in your animated GIF file:
Make sure that you enter at least 20 FPS in the bottom left edit box, otherwise the recording will be low quality. Press record. A dialog will first appear, and you choose here whether you want your GIF file to be in an infinite loop, or just repeated once, or any number of times. Also an interesting option is to add some visual clues for mouse clicks. Choose also filename, and press Save.
Now you do whatever you have to do to trigger animations. I pressed buttons Grouped and Stacked several times. After I decided it's enough, I pressed Stop. The resulting file is:
That's it!
Is it possible to create an inline png image, e.g. using matplotlib, and re-using it in a markdown cell (via html) without saving it on hard disk first?
IPython notebook saves inline images in the ipynb file, so the data is available, I wonder if it is also accessible?
One idea is to generate images for pretty slides (cell mode) and to to suppress the slides for image creation.
No it is not possible without saving the image. Using slide mode you can exclude some cells. is is also possible to use slide-mode and not to show the code if you are using custom templates.
I am trying to download a number of images, of differnet sizes, then after some cropping stitch them into one single image.
I am intending to do this in code on a WP7 device
My current approach uses n Image controls and waits for their ImageOpened events to fire. Once they have all been successfully opened I create a new Image for each and stick them into a StackPanel.
In then use WriteableBitmap to create a single image from the stacked images.
This code works 40/50% of the time. The rest of the time the layout engine decides to not bother laying them out in a horizontal stack. All the images get rendered on top of each other.
Is there a way of forcing the StackPanel to do a full layout pass? I have tried combinations of Arrange and Measure on both the Images and the StackPanel.
I found the article WP7: Generate Live Tile Images Locally (Without The Visual Tree). I am now using Henry Chong’s approach (which includes UpdateLayout) and my photo stitching is working great.
I cannot help but be amused by the fact that the answer to my question “how the hell do I force the layout to be updated” was answered with a method called “UpdateLayout” [dev exits stage left kicking himself]
