TRANSFORM/ROLL

THAT'S THE EFFECT IN "TRANSFORM" THAT ENABLES YOU TO MOVE YOUR GRAPHIC UP , DOWN, RIGHT OR LEFT

HERE IS THE PARAMETER WRITE-UP FROM IMAGE MAGICK:
Roll = roll an image vertically or horizontally.
The parameter has this format: {+-}{+-}
A positive x offset rolls the image left-to-right.
A positive y offset rolls the image top-to-bottom.
A negative x offset rolls the image right-to-left.
A negative y offset rolls the image bottom-to-top.

HOW IN THE HECK DO I READ THIS?

ABOVE IS A GOOD EXAMPLE OF HOW IMAGE MAGICK EXPLAINS PARAMETERS AND A GOOD LEARNING TOOL FOR US TO "DECIPHER" THEIR LANGUAGE TOGETHER

The parameter has this format: {+-}{+-}
THAT MEANS,,,, POSITIVE OR NEGATIVE X
POSTIVE OR NEGATIVE Y
+X+Y OR -X+Y OR +X-Y OR -X-Y

THINK OF A CROSS IN THE MIDDLE OF YOUR GRAPHIC UPPER LEFT HAND CORNER = +X+Y
+X OR GOING TO THE RIGHT
+Y OR GOING TO THE BOTTOM
UPPER RIGHT HAND CORNER= -X+Y
-X OR GOING TO THE LEFT
+Y OR GOING TO THE BOTTOM
LOWER LEFT HAND CORNER= +X-Y
+X=GOING TO THE RIGHT
-Y=GOING TO THE TOP
LOWER RIGHT HAND CORNER -X-Y
-X=GOING TO THE LEFT
-Y=GOING TO THE TOP
AND THAT IS HOW YOUR GRAPHIC IS GOING TO "ROLL" DEPENDING ON WHAT PARAMETER NUMBER YOU GIVE IT.


DIAGRAM FOR "TRANSFORM/ROLL"

EXAMPLE:
YOU HAVE A GRAPHIC 300X300
IF YOU SPECIFY: -50-50
WHERE IS YOUR GRAPHIC GOING TO "ROLL"?
LOOK UP ABOVE AT LAYOUT
IT IS GOING TO "ROLL" 50 PIXELS TO THE LEFT AND 50 PIXELS TO THE TOP.
EXAMPLE:
IF YOU SPECIFY: +75-25
WHERE IS YOUR GRAPHIC GOING TO "ROLL"?
75 PIXELS TO THE RIGHT AND 25 PIXELS TO THE TOP
IS THIS BECOMING CLEARER NOW?
THINK OF IT AS IF YOU ARE PLACING YOUR ANNOTATION SOMEWHERE

NOW WHAT WOULD HAPPEN IF YOU HAVE A GRAPHIC 300X300 AND YOU SPECIFIED: -400+350 OHOH,,,,,,WHAT HAPPENS??!!!!???
IF/WHEN YOU MIGHT SPECIFY A NUMBER HIGHER THAN THE WIDTH/HEIGHT OF YOUR GRAPHIC
( I DON'T KNOW WHY YOU REALLY WOULDN'T NEED TO BUT WHAT IF?)

WHEN USING "ROLL" A PARAMETER GREATER THAN, WILL WRAP AROUND ITSELF
AGAIN YOU HAVE A GRAPHIC 300X300
-400 WOULD WRAP ALLL THE WAY AROUND ITSELF AND BE EQUIVALENT TO -100.
+350 WOULD WRAP ALL THE WAY AROUND ITSELF AND BE EQUIVALENT TO +50
DID I CONFUSE YOU WITH THAT ONE?
THINK OF EITHER A SIDEWAYS OR LENGTHWISE "PULLEY SYSTEM" AND, IF YOU STIPULATE MORE THAN THE EQUIVALENT OF THE WIDTH OR HEIGHT, THEN YOUR GRAPHIC GOES AROUND THIS PULLEY SYSTEM AND ENDS UP WHATEVER AMOUNT YOU STIPULATED.

THIS "WRAP AROUND" EFFECT IS WHAT WILL DETERMINE
-WHERE ON YOUR GRAPHIC IS SOMETHING THAT YOU WANT TO "ROLL" TO SOMEWHERE ELSE.
-FIGURE OUT APPROXIMATELY WHAT PARAMETER AND PATH YOU NEED TO GET THERE
***THE MISTAKE OFTIMES HAPPENS OF USING THE MULTIPLICAND SIGN "X" BETWEEN 2 PARAMETERS BECAUSE IT IS USED SO OFTEN IN OTHER EFFECTS, MAKE SURE YOU LEAVE IT OUT HERE!!!!
JUST 2 PLACEMENTS X,Y
PLUS OR MINUS ON EACH.

***IMPORTANT: AT THE BOTTOM OF TRANSFORM, MAKE SURE YOU HAVE THE DROPDOWN BOX FOR "CENTER" POSITIONED AND ALSO "RESET PAGE GEOMETRY" CHECKMARKED.

DO THAT EVERYTIME YOU USE SOMETHING IN "TRANSFORM" OTHERWISE YOU ARE COMING FROM THE NORTHWEST AND YOU ARE GOING TO GET A WHITE BORDER AROUND PART OF YOUR IMAGES. IF YOU SEE THAT, THEN REMEMBER: YOU FORGOT TO DO THESE 2 THINGS!!!

-TAKE A GRAPHIC
-TRANSFORM/ ROLL IT HOWEVER YOU WISH
(IF YOU RAISE SINK IT FIRST THAT TURNS OUT PRETTY KEWL..SEE FOR YOURSELF!!)
-POST IT HERE ONLY WITH THOSE STEPS.

AFTER THAT, GO ON TO "WEEKEND CHALLENGE OR DO WHATEVER YOU WISH.

ANY QUESTIONS ??? PLEASE POST THEM ON THE BOARD.
