You can make translucent versions of any opaque color, simply by setting the alpha channel to less than 255 When you draw any color that s not fully opaque, the RGB is blended with the existing RGB according to the alpha level That is, the RGB component of each pixel is set to the existing RGB component plus alpha/255f times the difference between the new component and the existing component2 For example, an alpha level of 64 (0x40) is roughly one quarter Drawing an ARGB of 0x40506070 onto an RGB of 0x4080C0 will result in an RGB of 0x40 + (0x50 - 0x40) * 64/255f, 0x80 + (0x60 - 0x80) * 64/255f, 0xC0 + (0x70 - 0xC0) * 64/255f or 0x4478AC (See the 16\AlphaTest Delphi project) The Color structure has a set of static FromArgb methods that return a Color given various different sets of parameters.

Figure 2-20. The announcements list appears in the Left web part zone. By default, a newly added web part always appears at the top of the zone. If you would prefer to rearrange the order of the web parts in the zone, click and drag the web part by its header to another position within the zone. You can also click and drag the web part to another zone by dragging it to the position in that zone where you want it to appear. When you have your web parts arranged the way you like, click the link in the upper-right portion of the screen below the Site Actions button labeled Exit Edit Mode. You can now see how your site s home page displays the new list.

You can create a Color from R, G, and B components; from A, R, G, and B components; from a single integer that specifies the ARGB levels as AARRGGBB; or from an existing Color and a new alpha level This last overload is particularly useful in generating transparent versions of existing colors: for example, ColorFromArgb(0x7F, ColorWhite) returns a 50% opaque white Color In color circles, RGB and ARGB are considered implementation details, much like the Cyan/Magenta/Yellow/Black (CMYK) that printers use The color-centric coordinate system of choice is HSB for Hue, Saturation, and Brightness HSB is a polar coordinate system, with one rotation coordinate and two displacement coordinates Hue is a float that specifies degrees, 0 to 360 Imagine the Newtonian colors red, orange, yellow, green, blue, indigo, and violet arranged around a wheel, so that red is next to both orange and violet.

By implementing a __toString() method, you can control how your objects represent themselves when printed. __toString() should be written to return a string value. The method is invoked automatically when your object is passed to print or echo, and its return value is substituted. Let s add a __toString() version to a minimal Person class: class Person { function getName() { return "Bob"; } function getAge() { return 44; } function __toString() { $desc = $this->getName(); $desc .= " (age ".$this->getAge().")"; return $desc; } } Now when we print a Person object, the object will resolve to this: $person = new Person(); print $person; Bob (age 44) The __toString() method is particularly useful for logging and error reporting, and for classes whose main task is to convey information. The Exception class, for example, summarizes exception data in its __toString() method.
