I need to have a way to convert a small amount of html text to a jpg, preferably using coldfusion, but if there is another way that I can use and embed successfully, that may work too.

If you're on ColdFusion 8, you can use the <cfimage> tag to do what you need.

These links appear to be making thumbnails from pdfs, I will look into cfimage to see what I can do.

Yes, but you may be misunderstanding.  They convert html to a pdf variable, then convert it to a jpg.  You can of course use cfimage, but cfimage cannot handle html.  That is why you may be better off using the technique in the links. It is far easier to handle html (<b>, <h1>, etc...) with cfdocument.

... of course if you just want to draw plain text on an image, then yes .. you should just use cfimage.

To answer your previous question, to draw plain text on an image use the ImageDrawText function.   Attached is a simple example, but you can also find more information about this and other image functions in the online documentation:

You might also be interested in this cfc at riaforge.cfc.  It is not text specific, but does have a few neat functions for rendering text on images:

http://imageutils.riaforge.org/




<cfset img = ImageNew("", 275, 60, "argb")>
<!--- change a few font properties --->
<cfset fontProp = { font="verdana", size="30" }>
 
<!--- draw the first word in blue text --->
<cfset ImageSetDrawingColor(img, "0000ff")>
<cfset ImageDrawText(img, "Draw", 10, 30, fontProp)>
 
<!--- draw the second word in blue text --->
<cfset ImageSetDrawingColor(img, "ff0000")>
<cfset ImageDrawText(img, "Something!", 85, 50, fontProp)>
 
<!--- show the sample image --->
<cfimage action="writeToBrowser" source="#img#">

I just tested that, and it would work great, actually. Is there a way to save as JPG and save to a particular file?

Sure.  Either use the ImageWrite(..) function or the cfimage tag to save the image to disk:

<cfset img = ImageNew("", 275, 60, "argb")>
... other code
<cfset ImageDrawText(img, "Something!", 85, 50, fontProp)>
<cfset ImageWrite(img, "c:\whateverPathYouWant\theImageNameYouWant.jpg")>

This is brilliant. One more thing - can I set the background color? perhaps by drawing a square the size of the image?

Yes. Background color is one of the parameters for the ImageNew(..) function.  Just use any hex color.

<cfset img = ImageNew([source, width, height, imageType, canvasColor])> .... ie
<cfset img = ImageNew("", 275, 60, "argb", "FFFFFF")>
