Is it possible to use rangeWidget on Tiff images using visad.util.RangeWidget?
I have used RangeWidget on ".nc" files.
And the use of RangeWidget is given here:( Eg: 2.10 , 2.11 )

Yes it is possible the same way given in example, It was a logical error.
I was rerendering an image so changes are not displayed.

I am new in automation and want to automate a site whose back-end in HTML5 and containing canvas element.
I want to compare canvas images with my stored image.
For image comparison I need to use robot framework.
I had tried with "robotframework-imagehorizonlibrary" library but still testcases were failed.
Can any one please help me.
Thanks.
I would suggest the RobotAppEyes Library, which is basically an extended version of Selenium2 library, and it actually has a keyword named Compare Images.
Use it as the following:
Compare Image <path, imagename=None, ignore_mismatch=False, includeEyesLog=False, httpDebugLog=False>
see details here: http://navinet.github.io/Robot-AppEyes/RobotAppEyes-KeywordDocumentation.html
I use sphinx to generate PDF files，but when I use csv-table to generate pdf,I found the generated csv-table could not skip pages automatically? How do I fix it?
You might want to try the Sphinx builder included with rinohtype, which offers a drop-in replacement for the LaTeX builder.
rinohtype will split your tables across pages. It can also automatically size table column widths, unlike the LaTeX builder. Another advantage is that rinohtype's PDF output can be styled more easily by means of CSS-like style sheets in case you need this.
(Full disclosure: I am the author of rinohtype)
I solved this problem by adding the class longtable
.. csv-table::
:file: path-to-csv-file
:class: longtable
I'm trying to find ways to get the Compression property from TIFF images. I found a method as shown here that works, but I'm wondering if i can use the System.Windows.Media.Imaging namespace to do this?
Looking at TiffBitmapEncoder.Compression it says:
"Gets or sets a value that indicates the type of compression that is used by this Tagged Image File Format (TIFF) image."
I'm not sure if i'm interpreting this correctly, but how would one GET the value?
I saw a lot of file up loader plugins .I dont want to use the entire file upload plugin ..
Means , I am using my own code. But i didnt find a way to restrict the file type the uploader accepts .. How can i do that? . Is there any plugin which doing only this function ( I don't want to use a full file uploader plugin)
This requires HTML5, jQuery is not needed. I think it will be small enough to use pure JavaScript:
first you can set the accept attribute to image/*
after that you can use the File Api to read the first bytes for the magic number - image numbers demo
These are just some ideas. You can devise some heuristic to check the file type based on this.
I have a webpage which contains about 20 - 50 dynamic images (images served from a non-static source). These images are served through a servlet based on the request URL. This results in a request being generated per image, which leads to performance decay.
If these images were static, I would create a CSS sprite and replace the 50 requests with a single one. As they are dynamic this is not that easy of course. I'm looking for a tool/library/method that I can use in order to aggregate these images into a single sprite at runtime. Luckily image size is constant and the same for all, which should make this much easier.
Any suggestions?
You can check and try jawr (https://jawr.dev.java.net/) library for generating/modifying (also compressing, merging) css files on servlet. It has option to change background images dynamically.
You may arrange bundles for switching css file(s) for changing skin(s).
Plus side: You can also manage and arrange your .js files too!
You can append images with the free ImageMagick library, via a call to the system command line, so you have a lot less to code in Java and it is faster.
For appending horizontally, use this command:
convert image1.gif image2.gif image3.gif +append result.gif
For appending vertically, use this command:
convert image1.gif image2.gif image3.gif -append result.gif
For more informations: http://www.imagemagick.org/Usage/layers/#append
So, with CSS you can display the sprites using a single image with a simple offset (you can use the CSS "background" propriety for load the image and set the offset of the single sprite that you want to display). No JavaScript is required if you do only simple things.
Is the processing overhead on the server worth it?
I'm thinking about this now for C#, trading of the added complexity creating the dynamic images and sending them to the client, with the reduction in individual image accesses.
A trade off worthy of a bit of analysis.
