Warp is adding a white border on my images

[Jarrod5CDC]

I use the warp tool on images. Not sure when this started but everytime I warp an image, it creates a white border around the image. How do I go back to just warping an image without changing the color?

This happens because at the edges of your raster image there is some resampling and smoothing taking place.

Jarrod,

You can cheat/make a cover up (literally) as follows:

1) With the Rectangle Tool ClickDrag out a stroke/nofill rectangle between two opposite corners of the image (part you wish to use) and Group it with the image (Smart Guides are your friends);

2) Warp;

3) Select the rectangle (you can Direct Select it by its original shape (after deselecting), or select it through the Layers palette), then give it the same colour as the background and a sufficient Stroke Weight to cover up the pale part.

It is best if you can use a wee bit larger (part of the) image so you can afford the snipping off round the edges.

Similar cheating can be used for Envelope Distort.
