ColdFusion 8: Rounded Corners & Reflection
Posted by David in ColdFusion on August 28, 2007
As you may have known, Foundeo has created an Image Effects CFC that can generate image gradients, reflection, drop shadows, and some more cool effects by taking advantage of the new image features in ColdFusion 8.
Some people have been trying to replicate some of the functions this package has, especially the gradients, reflection and rounded corners functions. John Hartmann did an excellent job in replicating the reflect() and gradientMask() functions.
Jeff Coughlin also started building a CFImage Effects Plugin for FarCry based off of John Hartmann's functions. His Plugin has code to replicate the rounded corners.
Now, lets get into the code...
Search Thru a Multi-Dimensional Array
Posted by David in ColdFusion on August 24, 2007
I ran into a situation today where I needed to search thru a multi-dimensional array to update quantities and total prices for backordered products coming from a query. Unfortunately ColdFusion doesn't have an ArrayFind() function like it does for structs. I did a search on CFLib and found a UDF that did the trick.
The ArrayFindByDimension() UDF allows you to pass it an array, the value to find, dimension to search and returns the numeric array position if found, 0 if not found.
Here is some of my sample code:
<!---
Search a multidimensional array for a value.
@param arrayToSearch Array to search. (Required)
@param valueToFind Value to find. (Required)
@param dimensionToSearch Dimension to search. (Required)
@return Returns a number.

}

return 0;

ColdFusion 8: Watermarks, Transparency & Resizing
Posted by David in ColdFusion on August 22, 2007
I wanted to share some code examples that I have come across within the past few weeks regarding the new functionality in ColdFusion 8. My first example will be using the following functions: ImageRead(), ImageSetAntialiasing(), ImageScaleToFit(), ImageSetDrawingTransparency(), ImageGetWidth(), ImageGetHeight(), and finally ImagePaste(). Ok, here we go...

Adobe MAX Map Embedded
Posted by David in MAX on August 21, 2007
Last month I posted a link to a google map I created with all the hotels, airports and venue mapped onto one map. Google has made it one step easier in sharing their maps. Now you can embed their maps directly into a webpage. Check it out!
