flip objext or text in JS

[Guest]

I can't find a way to flip an object or text horizontally or vertically using javascript. I looked at the transfomation matrix but that looks like it only scales, offsets and rotates an object or text.

Can I flip an object or text (horizontally or vertically) using javascript?

Thanks,

Mark

Try scaling it -100% in the direction you want it to flip

This is AppleScript but may provide an indication to the values you require for your matrix in JavaScript.

I did notice that even with about centre some times the bounds moved so I get the position then reposition you will need to test.

Transform about vertical axis:

tell application "Adobe Illustrator"

activate

set Doc_Ref to the current document

tell Doc_Ref

set Group_XY to position of group item 1 of layer 1

set RefVert_Matrix to ¬

{class:matrix, mvalue_a:-1.0, mvalue_b:0.0, mvalue_c:0.0, mvalue_d:1.0, mvalue_tx:0.0, mvalue_ty:0.0}

transform group item 1 of layer 1 using RefVert_Matrix about center

set position of group item 1 of layer 1 to Group_XY

end tell

end tell

Transform about horizontal axis:

tell application "Adobe Illustrator"

activate

set Doc_Ref to the current document

tell Doc_Ref

set Group_XY to position of group item 1 of layer 1

set RefHoz_Matrix to ¬

{class:matrix, mvalue_a:1.0, mvalue_b:0.0, mvalue_c:0.0, mvalue_d:-1.0, mvalue_tx:0.0, mvalue_ty:0.0}

transform group item 1 of layer 1 using RefHoz_Matrix about center

set position of group item 1 of layer 1 to Group_XY

end tell

end tell

hope this helps

Thanks guys. It wasn't obvious to me that "-" scale would flip the object.

In JS:

var mytextframe = mydoc.textFrames.add();
mytextframe.contents = "TEXT";

var myMatrix = getScaleMatrix(100,-100);  //100,-100 flip vert, -100,100  flip horiz
mytextframe.transform(myMatrix);

Thanks again,

Mark
