How to crop image in Image_Canvas PHP PEAR package -

-

I can not get it to work just does nothing I use the Image_Canvas PEAR package on shared hosting I am doing but I can not crop the image.

My syntax is: 

  $ canvas-> SetClugging (array 'X0' => 10, 'y0' => 10, 'x1' => 200, 'y1' => 200));

Any ideas?

I'm not familiar with that image Image_Canvas peer package, but I've just tried to do it and Have found that if setClipping you will add a second call to the same method without any parameters! 

  $ Canvas = & amp; Image_Canvas :: factory ((isset ($ _GET ['canvas']) $ _GET ['canvas']: 'PNG', array ('width' => 500, 'height' => 333, 'file name' = & Gt; 'yourImage.jpg')); $ Canvas-> Setting (array ('x0' => 10, 'y0' => 10, 'x1' => 200, 'y1' => 200)); $ Canvas-> Image (array ('x' => 0, 'y' => 0, 'filename' = & gt; './yourImage.jpg')); $ Canvas-> SetClipping (); $ Canvas-> Show ();

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
