Download an image to local machine

Does it expire immediately or after some time?

It expires immediately. Once I save it to local machine and open it. It displays image expired.

Thanks

That's because the chart is stored in the cache and once the cache expires the image is no longer available. The image is not being stored in the Excel file - it's just a link. You can try copying the chart to another location outside the cache and link to that instead.

Hi,

I tried to save the image by using the following code

<cffile
action="WRITE"
file="mychart.jpg"
output="#myChart#">

I set name attribute of cfchart to myChart.
Then I tried to view image by <img src="new.jpg"> but it is not displayed.
I checked whether image is present in the location and it was present.
I also set debugging off by <cfsetting showdebugoutput="no"> . Still its not working.

Try specifying the full path to the file:
Also note that you're checking for new.jpg instead of mychart.jpg.

Try specifying the full path to the file:

Expand|Select|Wrap|Line Numbers

1. <cffile 
2.             action="WRITE" 
3.             file="c:\images\mychart.jpg" 
4.             output="#myChart#">

Also note that you're checking for new.jpg instead of mychart.jpg.

Hi,

I tried giving the whole path. Still when it retrieve the image is empty.
But image is present in the location.

new.jpg was a mistake and is corrected.
Thanks

Hi,

I found it is problem with path. Image is getting stored in default path and when I try to retrieve it is searching in current directory. I am not able to specify the default path. It is appending it to the URL

Use an absolute path. If you want the default directory, it will usually be the temp directory which you can get with getTempDirectory().

Thankyou acoder. With getTempDirectory() I am able to get temp directory and download as an image file. Only problem is I am not able to download as excel. When I download as excel it is giving binary format not image.

If you try any normal image (not one generated using cfchart), is it still in binary format?
