Railo / ColdFusion – Writing Image to Outpout Stream

Hello guys, Needed to do this for a project my team is maintaining, but I could only find the solution for ColdFusion, which looks like this: JavaImport = structNew(); JavaImport.io = structNew(); JavaImport.io.File = CreateObject('java', 'java.io.File'); JavaxImport = StructNew(); JavaxImport.imageio = StructNew(); JavaxImport.imageio.ImageIO = CreateObject('java', 'javax.imageio.ImageIO'); imageBuffer = JavaxImport.imageio.ImageIO.read(JavaImport.io.File.Init(imagePath)); response = getPageContext().getFusionContext().getResponse(); response.setHeader('Content-Type', 'image/png'); response.setHeader('Cache-Control', 'max-age=604800, public'); JavaxImport.imageio.ImageIO.write(imageBuffer, "png", response.getResponse().getOutputStream() ); After consulting Railo documentation on GetPageContext method, we've come to the following result: JavaImport = structNew(); JavaImport.io = structNew(); JavaImport.io.File = CreateObject('java', 'java.io.File'); JavaxImport = StructNew(); JavaxImport.imageio = StructNew(); JavaxImport.imageio.ImageIO = CreateObject('java', 'javax.imageio.ImageIO'); imageBuffer = JavaxImport.imageio.ImageIO.read(JavaImport.io.File.Init(imagePath)); response = getPageContext(); response.setHeader('Content-Type', 'image/png'); response.setHeader('Cache-Control', 'max-age=604800, public'); JavaxImport.imageio.ImageIO.write(imageBuffer, "png", response.getResponseStream() ); How it will be useful to you as well....

CFML Generating Random String

While working on one of my client’s projects, I’ve encountered the need of generating RANDOM strings. Since, as almost, any other language, Cold Fusion does not have any type of support for this functionality, I had to create a function of my own.

Hope you find it useful.

Zend framework 2 generating route url with domain name

Nothing more than this little line of code: $homeUrl = $this->url( 'youRouteName', array(/* your route params */), array('force_canonical' => true) ); Of course, you need to call it within a code zone where you can invoke the URL helper. What you see above, assumes that you are in a .phtml file invoked by a controller's action....

Nothing more than this little ...

Dumping object inside cfscript tag

I’ve been looking for this a few times now, until now i’ve found two interesting options.

One is creating a cffunction of your own, and using it inside a cfscript afterwards:

<CFFUNCTION NAME="MyDump">
    <CFARGUMENT NAME="OBJ" Required="TRUE">
    <CFDUMP VAR="#Obj#">
</CFFUNCTION>

window.setTimeout call functions with parameters / DOM vs MSDN vs MDN

One of my latest WTFs came from a javascript diference between the MSDN (yes… Microsoft Developer Network) and the rest of the world which may actually follow the latest DOM description.

Even though, w3schools.com still presents this as MSDN does, I’m pretty sure the DOM evolved since. So let’s see:

NOTE:
+ I will try not to re-write again all the informations I already wrote in “Java Media Framwork vs IP Camera JPEG/MJPEG” a few years ago. This article is only a review of what I wrote back then, plus more info about my implementation of DataSource for JPEG/MJPEG IP Cameras.

IP/TCP/UDP header vs C/C++

NOTE: This article is written in Romanian, for a translation please add me a comment.

Ei bine… nu mare imi fu uimirea dupa ultimile proiecte / teme, mici aplicatii. Uimirea ca habar nu am sa scriu un header tcp. Toata povestea a plecat de la o tema pentru facultate. Un modul de kernel linux/windows care trebuia sa filtreze pachetele TCP si UDP.

Permission denied to call method XMLHttpRequest.open

Have you ever seen something like that? I recently had a very interesting experience within AJAX scripting. Let’s say you will access http://www.domain.ext, right? Now here comes my problem.
