[SOLVED] - Resize Canvas, Transparent BackGround

Postby Jynks » Mon Aug 15, 2016 3:15 am

Hi there...

I have a number of PNG files with transparency, but for technical reasons I need the expand the total canvas size of the image. I tried using XnConvert but I can not seem to work out how to do the canvas resize with out the new space being created being filed with a solid colour.

SOLUTION

When making some screenshots to phrase my question properly I discovered the solution to this. Sorry to waste your time, but I thought I would still make the thread in case others come here who are equally as much a silly bunny.

This image shows a simple resize image and then resize canvas function... in the resize canvas function I have circled the value that controls transparency for the new space created when you increase the size of a canvas.

Just a quick follow up.... if you are trying to get transparent backgrounds from a Canvas Resize and the source is like a jpg or something you need to add a action to add the alpha channel

Image

This is the same simple reze action as before but before the canvas I have added the "Change Colour Depth" filter and simply ticked "32bit" and set the Alpha to 255.

Finally in your output make sure you have selected a format that supports alpha channels.. like say PNG....

Thanks for the help guys!!
