java - Check if a file is an image -


I am using JAI and am making a file on it: 

  Plain Image IMG = JAI ("File Load", MyFileName);

When the file exists, I check it before the line.

The image magnetic project has the ability to identify the image and there is a Java cover for the image magic , Which is called JMK, which I think you might want to consider instead of changing the wheel again:

I am using image magics all the time, It also includes its "detection" feature from the command line and it has failed to identify a photo.

It needed that feature completely and JMG had not yet existed, but I used to command Java code for Runtime.XAC () ImageMagick identity And it used to work perfectly.

Nowadays, JMG has existed, perhaps it is not necessary now (but I have not tried JMGC yet).

Note That it just gives more than the format, for example: 

  $ Identification tmp3.jpg tmp3.jpg JPEG 1680x1050 1680x1050 + 0 + 0 Direct class 8-bit 293 $ 582kb $ detection tmp.png tmp.png PNG 1012x900 1012x900 + 0 + Direct class 8-bit 475.119kb

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
