How to use transform="matrix()..." of SVG

Stanlepunk

I try to work around the text from SVG, and I must use the matrix but I find nothing to help for used it. any idea ? <text transform="matrix(1 0 0 1 30.5698 85.9966)" class="st0 st1 st2">super ROPE</text>

The first four numbers are the rotation matrix, the identity matrix here, no rotation.

The next two are probably translation, so position in this case.

I know a,b,c,d arg is some time for rotation argument and e and f for position, but I want code some algorithm to use text from svg in Processing, not just for the position, but also for the other transformation : rotation, skew... https://www.w3.org/TR/SVG/coords.html

So loadDisplaySVG() doesn't load text?

If not, have you tried looking at the source code on github to see how it already handles the matrix for non-text elements?

Processing cannot display text and don't use style tag from Illustrator CC, so a work arount that.

Finnaly I find the solution to work with the transform:matrix(a,b,c,d,tx,ty)

Thanks for sharing your work and the example sketch! I wonder if svg text parsing could become a library -- or just part of a Processing upgrade....

Stanlepunk

You're welcome ! You can use the Z_tab from the sketch like a library if you want. May be in the future I make a library with that or better push something for Processing :)
