Hi all,

I have created a PSD using ArtRage for my IPad and emailed across for some editing in Photoshop.

Now because I have not set the pencil as having a hard edge in ArtRage, when I save to a PNG there is a semi-transparent line of pixels around the image.

I would like to remove these is there a tool I can use on photoshop to do this automatically? or do I have to painstakingly remove them with an eraser?

The easiest way to loose the semi-transparent pixels would be to convert the png-24 to a png-8. Png-8 does not support alpha channels, (semi-transparency).

The down side, is that it also only supports 256 colors. Surprisingly, this sometimes is not a problem.

Open in Photoshop, go to File > Save for web and devices. Set the screen for two up, original and preview. Where the pull down menu says PNG-24 select PNG 8. If that is the result you want, press save.

If not, some sort of hand editing is probably involved.

To Trim away translucent pixels.

All depending on the subject, there are some shortcuts to hand editing. Open the image in Photoshop, and with the magic wand tool, click on the empty background to select it.

Then go to Select > Inverse. Now your image is selected, translucent pixels and all.

Go to Select > Refine Edge.

Use the Shift Edge slider to move the selection inward to cut off the transparent pixels.

To Make translucent pixels not translucent.

Simply duplicate the background layer five or six times (Ctrl+J) Then save as a PNG
