Hi there!
I have some script that creates a new image with ImageNew and performs
a few tasks. I'd like to output it without having to save it to disk.
On another application on another server I was able to use <cfcontent
type="image/jpeg"> to output an image read in as either a binary file
with <cffile action="readbinary"> or blob data retrieved from a
database. I am trying to output similarly in this case, but I can't
seem to turn my ImageNew img into binary.
Here is exactly how I'm creating the image right now...
<cffile action="READBINARY" file="#ExpandPath(
'originals/img1of2.jpg')#" variable="binImg1" />
<cfset img1 = ImageNew(binImg1)>
<cffile action="READBINARY" file="#ExpandPath(
'originals/img1of2.jpg')#" variable="binImg2" />
<cfset img2 = ImageNew(binImg2)>
<cfset w = MAX(img1.width, img2.width)>
<cfset h = img1.height + img2.height>
<cfscript>
imgFinal = ImageNew();
ImageResize(imgFinal, w, h);
</cfscript>
<cfset ImagePaste(imgFinal, img1, 0, 0)>
<cfset ImagePaste(imgFinal, img2, 0, img1.height)>
A Google search recommended <cfcontent type="image/jpeg"
variable="#ToBinary(ToBase64(imgFinal))#">, but this gives me a "data
not supported" error. I have of course also tried
"#ToBinary(imgFinal)#" and just "#imgFinal#".
I'm not sure if this is related or not, but on our other server I
mentioned, when I simply read in an img with <cffile
action="readbinary"> and then use <cfcontent type="image/jpeg">, I see
the image when I call the page. But the same code on THIS server
displays a bunch of garbled characters and boxes.
I should also mention that my ultimate end-goal is just to have a
function that can take two image file paths and return a virtual
combined image, and I know the normal way to handle this would be with
a CFC that just returns the image, but I have yet to solve my other
issue on this board regarding remote CFCs not being accessible.
