Change resolution of image from 72 to 25 dpi in PHP -

-

Do I want to change image resolution from 72 to 25 dpi using PDP?

Is this possible?

sorry .

Although you can try copying it, to say that you want to create 400x300, 25 dpi image, here's the math:

WIDTH 

  72 -------- 400 25 - ------- w = (25 * 400) / 72 (=) w ~ = 139 pixels

HEIGHT 

  72 -------- 300 25 ------ - h = (25 * 300) / 72 (=) H ~ = 104 pixels

You create a new 13 9x104 72dpi image, Work with it and you change it to a size of 400x300 pixels.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
