The following example creates a ColdFusion image with a 5-pixel blue border:. Post as a guest Name. The following example shows how to retrieve all of the information about an image: Of course I welcome and encourage followup and feedback here on this particular problem.
You can use the cfimage tag to perform common image manipulation operations as a shortcut to Image functions. Specify the thubmnail name in the attributeCollection attribute and use the tag’s attribute names as structure tnumbnail. The drawing attributes you specified are applied to the oval. Must be one of the following: For shapes, the first two values represent the x and y coordinates, respectively, of the upper-left corner of the shape.
Valid values are fractions that thumhnail from 0 through 1 the lower the number, the lower the quality. Also, you can create a blank image. The following table describes the ways to resize images in ColdFusion: The following example shows how to change image quality to.

Interpolation lets you control the trade-off between performance and image quality. If thumbnaul currently using CFIMAGE to do resizing, jump to the last section of this entry to see an example of code switching from the “slow” approach to the faster one.
ColdFusion resizes the image to fit the square or rectangle and maintains the aspect ratio of the source image.
Creating ColdFusion images
Sadly, I suspect most won’t do the math, so it’s a real good thing you mentioned the one taking 4-minutes. The drawing attributes you specified are applied to the line. This issue is somewhat urgent So to change from using the tag-based resize to function-based, you may need to add a line of code to load the image from disk, such as using imageNewand one to write the resulting image to disk, such as using imageWrite.
Converting images between one file format to another is time-consuming. Specify one of the following levels of text distortion: In this example, the width of the resulting image is less than or equal to pixels and the height of the image is less than or equal to pixels.
If fixed, that would be a new feature.
My client would be interested in upgrading to CF10 if PDF generation was better, but many of the new features weren’t compelling enough because we are already doing the same thing using third-party libraries and modules.
