I'm creating a company directory using our existing Active Directory information. I'm able to pull all the data I need, but I wanted to use Active Directory for the photo as well.
I found this snippet of code on this blog: http://plus10.blogspot.com/2008/02/coldfusion-cfldap-display-images-stored.html
<!--- imageFile.cfm --->
<cfsilent>
<cfldap action="QUERY"
name="ldap"
attributes="jpegPhoto"
start="dc=[yourdc],dc=com"
filter="sAMAccountName=[loginname]"
server="[yourserver]"
username="[username]"
password="[password]">
<cfscript>
ldapPhoto = toString(ldap.jpegPhoto);
ldapPhoto = binaryDecode(ldapPhoto,"base64");
</cfscript>
</cfsilent><cfcontent type="image/jpeg" variable="#ldapPhoto#">
<!--- to display the image on a page --->
<img src="imageFile.cfm" width="100" height="125" alt="">
I plugged in all my server data and I get the error
The image "....imagefile.cfm" cannot be displayed because it contains errors
Why isn't the image displaying? and how can I correct the code?
I did a <cfdump> on the query and it just shows as "jpegPhoto" not binary data.
I can't post the actual page because it is on an internal network only.
Note, the poster answered her own question. The cfcontent and img tags should be replaced with a cfimage tag using the source attribute and action="writeToBrowser"

ColdFusion CFLDAP - Display images stored in Microsoft Active Directory
Not too hard once I found out how MS stores the data in the photoJpeg field of Active Directory.
<!--- imageFile.cfm --->

start="dc=[yourdc],dc=com"
filter="sAMAccountName=[loginname]"

<cfscript>
ldapPhoto = toString(ldap.jpegPhoto);
ldapPhoto = binaryDecode(ldapPhoto,"base64");
</cfscript>
</cfsilent>
<cfcontent type="image/jpeg" variable="#ldapPhoto#">

I've never used cffile upload. In looking at the documentation I see that the file to be uploaded is described as
Name of form field used to select the file.
Do not use number signs (#) to specify the field name.
I just cannot decipher this. If the file to be uploaded is john.jpg, residing on the user's disk, how do I indicate that in the cffile command?
I have other questions as well, but would like to start with this very basic one.
What documentation are you using? There should be an example like there is here: <cffile action="upload">
In this example (which I've edited), it shows that you do not reference the name of the file that the user selected, that could be anything, you reference the name of the form field, fileContents, that is used to upload the file.
<!--- Windows Example --->
<!--- Check to see if the Form variable exists. --->
<cfif structKeyExists(Form, "FileContents") >
<!--- If TRUE, upload the file. --->
<cffile action = "upload"
fileField = "FileContents"
destination = "c:\files\upload\"
accept = "text/html"
nameConflict = "MakeUnique">
<cfelse>
<!--- If FALSE, show the Form. --->
<form method="post" action=<cfoutput>#cgi.script_name#</cfoutput>
name="uploadForm" enctype="multipart/form-data">
<input name="FileContents" type="file">
<input name="submit" type="submit" value="Upload File">
</form>
</cfif>
Once the CFFILE process completes, a collection of variables are defined in a structure named CFFILE (see documentation link). One of these variables is cffile.clientFile, which contains the name of the file that was uploaded from the user's computer.
For the cffile command:
<cffile action = "upload"
fileField = "FileContents"
destination = "c:\files\upload\"
accept = "text/html"
nameConflict = "MakeUnique"
result = "thisResult">
...you would use #thisResult.clientFile# to get the original filename.
All the other fields would be available using this also.
I found this on stackoverflow:
ColdFusion ServerFile is undefined in CFFile
curious one this.
I'm working on a process that generates PDF files, combining data from various sources. The last piece of this process I need to complete is merging in image files.
This is actually fairly straightforward but the problem I have is the image files aren't stored with file extensions. Locally, I can change the filename, but in production this isn't an option.
So because a filename looks like : B71637CB-A49C-0653-EF813918736BDEB7
This will not work:
<cfimage action="writeTobrowser" source="#FilePath#>
Same with
<img src="#FilePath#">.
So, any ideas on how I can work around this? Here's the code in context:
<cfdocument format="PDF" name="report" filename="#fileToDownloadimage#" overwrite="yes">
<cfdocumentsection>
<cfimage action="writeTobrowser" source="#FilePath#.jpg">
</cfdocumentsection>
</cfdocument>
So here's what ended up working:
<cfdocument format="PDF" name="report" filename="#fileToDownloadimage#" overwrite="yes">
<cfdocumentsection>
<cfset fileObject = fileReadBinary('#FilePath#') />
<cfset imageObject = imageNew(fileObject) />
<cfimage action="writeTobrowser" source="#imageObject#">
</cfdocumentsection>
</cfdocument>
Alex's answer got me down the right path so I'm perfectly happy to leave the kudos in place, cos I wasn't getting anywhere near this!
If you need to embed the images into the PDF document, try HTML's inline image capabilities:
<cfset fileLocation = "/path/to/images/B71637CB-A49C-0653-EF813918736BDEB7">
<cfset imageContent = fileReadBinary(fileLocation)>
<cfset imageContentAsBase64 = toBase64(imageContent)>
<cfoutput>
<img src="data:image/jpeg;base64, #imageContentAsBase64#" />
</cfoutput>
You can try creating a cfm page that outputs your content using cfcontent as in:
<cfcontent type="image/jpg" file="path/#fielpath#">
Then you would you include THAT cfm page as the source for your image as in
<img src="myFancyImageOuputer.cfm?image=#filepath#">
This should work but it may require some trial and error. :)

I am trying to create a spreadsheet (.XLS file) using Adobe ColdFusion - 8.
The code that creates a spreadsheet is:
<cfsetting enablecfoutputonly="Yes">
<cfset date_from = "#URL.date_from#">
<cfset date_to = "#URL.date_to#">
<cfset query_id="#URL.queryID#">
<cfquery name="GetEmps" datasource="cfdocexamples">
<!--- My SQL Queries Goes Here--->
</cfquery>
<cfcontent type="application/msexcel">
<cfheader name="Content-Disposition" value="filename=Employees.xls">
<cfoutput>
<table cols="4">
<cfloop query="getData">
<tr>
<td>#uid#</td>
<td>#week#</td>
<td>#book_count#</td>
</tr>
</cfloop>
</table>
</cfoutput>
Whenever I run the page, an XLS sheet is created, but I cannot find any data. The size of the created XLS file is 0.
Please Note: The Query is correct(Since when I print the output as html, I can see the table without any error/warning).
** After reading comments: UPD**:
I had updated my code and only included important code snippet now.
UPD 2:
Whenever I commented the line <cfsetting enablecfoutputonly="Yes"> , xls file is created with expected data. However, when I opened the generated file, a dialogue appears:
Please note the spreadsheet generated is perfect. Only thing that is bothering me is the above warning.
Also Note: whenever I tried to open the spreadsheet in google-docs as a preview, it says, the file could not be opened due to corrupted format.
However, I am able to open it perfectly in an MS-Excel.
Even changing content type to : <cfcontent type="application/vnd.msexcel"> , I got the same warning.
While I cannot speak exactly how to implement this, I know the developers within my organization worked around it with the Apache POI. It seemed to do the trick for them. It does have to be completed with Java through Coldfusion. Here is an example of it.
I have a service on a Coldfusion 9 server that creates image banners on the fly for us. A separate machine has to save these files with something like:
wget http://myserver.com/services/local/bannerCreator/250x250-v3.cfm?prodID=3&percentSaving=19
The problem is that I can't think of how to get coldfusion to write out binary data without using a temporary file. At the minute the image is just displayed as an image tag like this:
<cfimage action = "writeToBrowser" source="#banner#" width="#banner.width#" height="#banner.height#" />
Any ideas? Or should I just use a temporary file?
I can't test because you're not giving any example code for how your images are generated, but have you tried something along this line?
<cfcontent reset="true" variable="#imageData#" type="image/jpg" />
Update: So I went ahead and created my own image; I'll assume you're doing something similar. This works perfectly for me:
<cfset img = imageNew("",200,200,"rgb","red") />
<cfcontent variable="#toBinary(toBase64(img))#" type="image/png" reset="true" />
This works without writing to file, and without using a virtual file system ("ramdisk")
If you have the binary bytes of an file/image, you can replace the output buffer with it's contents like so:
<cfscript>
// eg. this is how you get a file as a binary stream
// var fileBytes = fileReadBinary( '/path/to/your/file.jpg' );
// get the http response
var response = getPageContext().getFusionContext().getResponse();
// set the appropriate mime type
response.setHeader( 'Content-Type', 'image/jpg' );
// replace the output stream contents with the binary
response.getOutputStream().writeThrough( fileBytes );
// leave immediately to ensure no whitespace is added
abort;
</cfscript>
Pretty much what <cfcontent> does when you use reset="true"
The advantage of this method over <cfcontent> is that we can write it inside our cfscript based cfcs.
I found the solution above
<cfcontent variable="#toBinary(toBase64(img))#" type="image/png" reset="true" />
to not quite work for me.
Setting type="image/png" is just setting the mime type of the response. I don't think it's necessarily encoding the image as PNG. As such, generating a transparent png (image type "argb") was giving me odd colours, when compared to the <cfimage action = "writeToBrowser"...> method.
I figured that somehow I needed to explicitly encode the image data as PNG and output the binary data directly.
With some digging around in the underlying java, I came up with this, which so far seems to work for me.
This example draws a transparent png with a black circle.
<!--- create the image and draw it --->
<cfset img = ImageNew("", 23, 23, "argb")>
<cfset ImageSetDrawingColor(img, "black")>
<cfset ImageDrawOval(img, 0, 0, 21, 21, true)>
<!--- get the response object --->
<cfset response = getPageContext().getFusionContext().getResponse()>
<!--- set the response mime type --->
<cfset response.setHeader('Content-Type', 'image/png')>
<!--- get the underlying image data --->
<cfset bImage = ImageGetBufferedImage(img)>
<!--- get the magical object to do the png encoding --->
<cfset ImageIO = createObject("java", "javax.imageio.ImageIO")>
<!--- encode the image data as png and write it directly to the response stream --->
<cfset ImageIO.write(bImage, "png", response.getResponse().getOutputStream())>
I hope that helps someone!
Take out the height and width attributes and add the format attribute:
<cfimage action = "writeToBrowser" source="#banner#" format="png" />
wget should honor the redirection to the physical file CF creates in the CFFileServlet folder but if it doesn't there is a flag you can set to make it --max-redirect=10.
And as you suggest, a temporary file would work too. Just write the file and use cfheader and cfcontent to write it out. Just make sure to make the temp file name more unique.
<cfimage action="write" destination="tempfile.png" source="#banner#" format="png" />
<cfheader name="content-disposition" value="attachment; filename=banner.png" />
<cfcontent file="tempfile.png" deletefile="true" type="image/png" />
I do a similar thing, and you need to combine using tags and cfscript. There are image functions that are required. There are a lot of image functions available, once you have an image in memory as a variable. You can get the image into memory using CFFILE or CFHTTP or a number of other ways.
In my case, I read an image file into memory using CFIMAGE tag, then manipulate it with CFSCRIPT image functions by adding text to the bottom, then outputting the resulting image as a .png (or a .jpg if you prefer) to the browser. The only file stored on the server is the original image file. In your case instead of reading in an image you'd call it using a cfhttp tag as you already do. Here's my code:
<!---Get the image for processing ...--->
<cfimage action="read" source="#application.approotABS#\webcam\webcam.jpg" name="CamImage" />
<!--- prepare the text for overlay --->
<cfscript>
attr=structNew();
attr.font = "Arial";
attr.size = 15;
ImageSetDrawingColor(CamImage, "white");
ImageDrawText(CamImage, 'LIVE FROM STUDIO 1', 18,(ImageGetHeight(CamImage)-54), attr);
ImageDrawText(CamImage, '#ShowOnNow.showname#', 18,(ImageGetHeight(CamImage)-36), attr);
ImageDrawText(CamImage, datestring,18,(ImageGetHeight(CamImage)-18), attr);
</cfscript>
<!--- further down the page, output the manipulated image: ---->
<div class="webcam">
<cfimage action="writeToBrowser" source="#Camimage#" >
</div>

(I am using CF9 with Windows Server )
I am using <cfdocument> tag of coldfusion 7. Using CFEclipse and working on MacOS.
I have written the following code:
<cfdocument format="pdf">
SitePoint.com - Introduction to ColdFusion 7
PDF Generation
This is an example of PDF generation using ColdFusion 7.
</cfdocument>
But instead of asking me to save this file in .pdf format, its trying to open it in .cfm format.
How can I save it in .pdf format? Thanks!
Unless you tell it otherwise, the webserver returns the results of a CFM call as text. You need to use CFContent with CFHeader to alert the browser that the results it will be recieving are of a different type. Something like:
<cfheader name="Content-Disposition" value="inline; filename=document.pdf">
<cfcontent type="application/x-pdf">
<cfdocument>...</cfdocument>
I may have the MIME type wrong there. I'm doing this from memory. Check the docs for more help.
If you are on CF8 or higher then use the saveAsName attribute:
<cfdocument saveAsName=""
Either that or the method suggested by Ben above should work
You might also need to import the style sheet as well. So you can get the desired formatting. It needs to be imported after cfdocument.
<cfdocument
format="pdf"
filename = "canwriteurfile.pdf"
overwrite = "yes"
marginBottom = ".2"
marginLeft = ".4"
marginRight = ".4"
marginTop = ".2">
<style type="text/css">#import "pdf.css";</style>
BLAHHH BLAHHH PDF FORMATTING STUFF
</cfdocument>
Try:
<cfdocument format="PDF" name="myPDF">
<html>
<body>
SitePoint.com - Introduction to ColdFusion 7
PDF Generation
This is an example of PDF generation using ColdFusion 7.
</body>
</html>
</cfdocument>
<cfpdf action = "write" destination = "pdf_path" source = "myPDF" overwrite = "yes"/>
<cflocation url="pdf_path"/>
Whis this you save the PDF on disk
