Splitting Images

[mike.]

I have this PNG file that is 1024X128 that I want to split into four separate images, each 256X128.

A quick mockup:

How do I go about doing that, if possible?

What I would do...

First split it into 3 images, using canvas size.

To do this:

• take your original image, and go to Image> canvas size
  uncheck the "maintain aspect ratio" box
  set pixel size to 256 width and 128 height
  set anchor point to Left
  click ok...that will give you your first 256x128 image, the left-most image
  save it as a separate image
  then click undo, and repeat the steps, except setting the anchor point to Right
  this will give you your right-most image...save that separate
  again, undo...
  go to canvas size one more time
  then set pixel size to 512 width and 128 height
  and set anchor point to middle
  this will yield the middle of the image, which you will hopefully know how to get to the correct size...

Or you could try using you rectangle selection to select 256 x 128 from the far left you'll be able to use the numbers down the bottom in the information bar. Cut that into a new image and do the same for the other two images except this time from the right side which leaves you the last 256 x 128 image and cut that into an new image and your done.

Thanks. I'll keep that in mind.

If I have image 6144x6144 pixels and i want split it in 512x512 pixels images, how do it faster way?

Maybe is there plugin for this?

[Curmudgeon]

holy cow...that'd be 144 separate images!

there's no automatic plugin for this (that I know of) nor do I know of any other image editor that has this ability

Paint.NET does not support this feature, but the GIMP does have a Slice tool that allows you to "slice" one single image and save each slice as a seperate file.

Edit: after checking, I realize that GIMP does not have a straight-up Slice tool, but it does have 2 filters that do simliar things. They are explained here.

In case anyone else needs to do this...
