RE: CF8 Image manipulation
Michael, Thanks for the reply. I already have that handled and it works great. I am drawing autocad type drawings using the new cf8 image tools and I was trying to find an easy way to add perspective, but now I am just going to force the user to be a little more precise by letting them define 3 points after they upload their photo along with the exact distances, then I can scale my drawings perfectly to their dimensions and problem solved. Coldfusion comes through again like always and thanks to everyone in CF-Talk as usual as you always start the juices flowing.

Re: CF8 Image manipulation
normal 8 handles? what is that? where is it 'normal to see them??? the only thing i can think of where an image has 8 handles when you click on it is M$ applications... and even then it is not always the case... what handles are you talking about?

Re: CF8 Image manipulation
Your browser is not an image editor - it cannot manipulate *any* images in this way -regardless of what server-side language/application generated them. To the browser there is no significant difference with the image downloaded from your server and any other image downloaded from the web. If your want your website users to be able to modify images in-browser, you will need either a Flash app or a specific browser plugin. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:320218 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: CF8 Image manipulation
Azadi, What I was trying to explain was normally when you click on an image object you get top left, top middle, top right, left, right, bottom left, bottom center and bottom right handles that you can then manipulate them. Sorry it was late.

RE: CF8 Image manipulation
I beg to differ, but I have a cfx_efflare and it allows me to click on an image and crop it on the admin area of my sites. I can click and drag to any part of the image and then resize to my heart's content. What I am looking for is a way to do a similar thing only basically change a rectangle into a trapezoid in order to make the perspective of the image I am placing over another fit perspective wise. Not trying to start a flame here, just looking for some new ideas.

I can click and drag to any part of the image and then resize to my heart's content. The last time I looked at CFX_Efflare, it didn't have any client-side functionality. But in any case, you would need client-side functionality to do this - just generating an image on the server is not enough.

RE: CF8 Image manipulation
Dave, I sent the guys at Efflare a the code I downloaded at http://www.defusion.org.uk/demos/060519/cropper.php And they sent me a script for cfx_imageflare to allow me to do the following: User uploads a photo, cfx_imagecr3 resizes to 760px with proper aspect ratio, optimizes to 72 dpi. The resulting image is then displayed in the browser. Then when the user clicks on the image the cropping code I got from the link above displays a 760px x 300px rectangle that can be dragged up-down to select the panoramic view to crop from the image when you click the submit button. I Have forced the width to be 760px for my task, but as you wull see in the demo link there is much, much more. But what I am looking for is how to use the same functionality as above. But to be able to decrease the bottom width and leave the top alone to create a trapezoid.

Re: CF8 Image manipulation
Cropping is easy, because JavaScript can mimic it with transparent/shaded backgrounds, and just send the coordinates of the corner back to the server to perform the actual manipulation. Likewise, normal resizing is also rectangular and easy to mimic in JS. Creating a trapezoid is more difficult, you wont be able to get a 'live preview', though you could use a similar technique to the cropping to define the widths of the top and bottom edge. However, there aren't any trapezoid/trapezium mainupulations with CF8s image functions - the closest is Skew/Shear which wont do what you want. I couldn't find any useful Java-based results either - apparently Java manipulations keep lines straight and parallel, which prevents trapezoiding as this obviously makes them non-parallel. Maybe you could investigate using GIMP on the command line to do this - although that appears to involve writing LISP... http://www.gimp.org/tutorials/Basic_Batch/ ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:320235 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
