How to use Imagick php to generate a bmp file with a palette offset -


I am trying to use iMagic to generate 8bit bmp from jpg via phag. But I would like to start pixel colors on index 16 compared to 0. In the code given below, how do I generate BMP in the correct format, but the palette index is missing from 0. Is there a way to ensure that the palette starts in another index?

$ average = new emacs ("icon.jpg"); $ Average-> setCompression (Imagick :: COMPRESSION_NO); $ Average-> quantizeImage (32, Imagick :: COLORSPACE_RGB, 0, wrong, incorrect); Image coloring (average, 0, 255, 255, 255); $ Average-> set format ("bmp"); Header ("content-type: image / bmp"); Rebound $ average; $ Average-> Clear (); $ Average-> Destroy (); I do not think Imagick has anything built for it, so you have to create a new palette (offset). Copy the old one with) and then use the $ pixel = $ average :: getImagePixelColor () and then $ pixel-> Getcolor ()

and $ pixel-> Set color () according to the new palette.

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

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...
