CROP & SHAVE - From Ron (PuzzleMan2):

Crop at IM...Shave, etc. is done at the Transform option at IM.

TO CROP: enter your #'s in the parameter box.

Bottom= +0-?
Top= -0+?
Left= +?-0
Right= -?-0

The amount you want to remove is put in place of the ? mark.
ie:... +0-20...will remove 20 pixels from the bottom.
Chk. Crop Transform.

TO SHAVE: In parameter box

10x10...takes 10 off all 4 sides.
0x10...takes 10 off top and bottom.
10x0...takes 10 off each side.

Just enter the amount you want removed from where.

Chk. Shave Transform.

You are going to find this is very easy once you get the hang of it.

Another explanation on how to set up the cropping parameters: Rose's Crop Tute.
CHOP-CROP: - From Diana (BDiana):

The easiest way to crop out the inside of a frame is to use PATH/DRAW or Polygon/DRAW and transparify it afterwards in PAINT.

CHOP/Crop from the inside out is another option. However, inside-chop is cropping out in "Slats", meaning the entire height/length of an image. If you have a frame image, that frame would loose width in its entire height: Y=+w+0 to Y=+w+h (of image).

CHOP from the inside out is very easy to use and only uses 3 numbers.

First number is the width of the 'slat' that you wish to chop out. It has to be followed by an 'x'.


If you intend to take out 50 pixels in the middle of an image, this is how you would enter it: 50x

Second number is where you wish to start the chop horizontally.

Third number is the height of the image. If you leave this number out, it defaults to Y 0,0, so it has to be entered.

However, you can crop out from the top or bottom border at the same time if you enter + (plus) or - (minus) numbers in relation to the height of image.

NOTE: the width and height of the image numbers are displayed in the titlebar.

The first number is width, the second is height. x=width, y=height.


Your image is 200x200 in width and height and you see it in the titlebar.

The desired slat you wish to chop out is 50 pixels in width.

You wish to start your chop 68 pixels IN from the left border.

Your parameter numbers would be: 50x +68+200

Note: there has to be a space between 50x and the first +.

The width and height in the titlebar should read after that CHOP: 150x200.

Or if you wish to take/crop 10 pixels off from the bottom border of your 200x200 image at the same time, your number would be: 50x +68+190.

The width and height in the titlebar should read after that CHOP: 150x190.

Or if you wish to take/crop 10 pixels off from the top border of your 200x200 image at the same time, your number would be: 50x +68-10.

The width and height in the titlebar should read after that CHOP: 150x190.

In all cases click on CHOP and TRANSFORM that's all there is to it.

CHOP from the outside borders IN is identical to CROP (from top left corner to bottom right corner coords).

1 more tip that I use.

The click and go method works great with CHOP inside=>out as well.

I enter the image

I click on VIEW

I click on the image and move the yellow cursor to the point where I wish my CHOP (left border) to start. I write down the first number that comes up underneath. (there are a bunch of numbers underneath coming up. The one to the very left and before the coma is the one we need).

I click again on the image and move the cursor where I wish my CHOP (right border) to end and write down the first number underneath again.

The DIFFERENCE between those 2 numbers is the width of my CHOP and my first number that I need for my parameters.

The first number I have written down is also my second number for my parameters.

The third number I need is the second number in the titlebar, aka the height of the image.

How easy is this?

Let's say I click on a 200x200 image first on 42 (left side of my chop)
then on 112 (right side of my chop).

a little math... 112-42= 70

The width of my desired chop is 70.
The starting point of my chop is 42.
The height of my image is 200.

My parameter numbers to enter would have to be: 70x +42+200

I hope that helps somewhat.
GET RID OF THE CENTER - From Susan (ERsigs):

If you want the "border" intact but not the image it's framing. The best way I know to do that is to first; crop off just the border, then use "paint" at "reset" with fill color "black" (this will give you a solid black bg the size of the "interior" of the image). Output to get the url, come back and click on "Input"-- the original url will still be there so just click on "view"-- then composite the black bg "over" (center +0+0) the original image.

At this point, you can output/save what is now a lovely border around a black bg, or you can use paint to "matte" the black and output/save as gif (to preserve the transparency so that the "border" can be comped over whatever image you have in mind).

Hope that makes sense! I mean, you could use "Chop" to actually "crop out the inside part" but all you'd be left with is the border... a very small border... with no room for an image (hope that makes sense, too!).

Be sure to check Stranjer's excellent tute, "Chop Out Image Interiors":

for a detailed method.
SIMPLE CROP - From Jean (lnjweaver):

Jean says she learned how to do this early on in her imaging career. This method enables you to crop off only one side or edge:

Remove from Bottom: +0-?
Remove from Left Side: +?-0
Remove from Top: -0+?
Remove from Right Sde: -?+0

Just substitute the number of pixels you want to remove for the ? in each.
