Equations macro works in 1.6, but not in 1.7


Recommended Posts

I wrote a macro to convert an image using a Cartesian to Polar conversion. It worked well in 1.6 and I describe it here. I have just tried it in the 1.7 beta and it no longer works. The output is a series of concentric colours, as if just the central axis has been rotated. I have tried running the original macro and also re-creating the macro with the same Equations.

Here are some images to illustrate this. First the original image:

Then the image with the macro applies, with the parameter set to approx 0.75:

Then the image opened in the 1.7 beta and the macro applied:

Here is the macro used in each case:

I have been trying other macros in 1.7 which rely on the Distort > Equations filter. None of them involving trigonometrical functions work. I have tried some without trig functions and they seem to work OK.

I used a simple checkerboard as a starting point: Checkerboard512.png.f59f9a15c41a3dc8c31280be437c211b.png

This is with the macro in Photo 1.6: 1126456012_Checkerboard512Wrap.png.3b709aea03dc4bacbb11e96de28427ab.png

And the result from Photo 1.7: Checkerboard512Wrap.png.10c9e0ac3cfee90853aabb2d65010a77.png

This is the macro. It is for wrapping an image around a bottle: WrapAround.afmacro

A final comment. I imported this macro into Photo 1.7, then exported it . I then imported it into Photo 1.6. It loaded OK, but would not work. (it did nothing. No error messages.)

Obviously, macros from version 1.6 do not work with 1.7

As mentioned in my second posting here, those macros I have tried that do not utilize trigonometric functions do seem to work properly, including those using Filters > Distort > Equations. I have not tried all my macros though.

I've posted on your other link re the use of trig functions.

 

There have been some changes - trig functions either must take angle values, or now return angle values.  This currently defaults to dealing in degrees, not radians.  I can't recall now what the trig functions used to do.  I have made a lot of changes between 1.6 and 1.7 to expressions - unit types have been tightened up.  ie, distances and angles cannot be mixed up.

I tell a lie - the distortion filters appear to be dealing in Radians.  It might be that 1.6 was treating the atan as degrees and now it is radians.  Like I say - a lot has changed...

My recollection is that the original function I used worked in degrees. This was probably why I needed the 100.

I will need to revise my other macros using trig functions!

I'm thinking that an option to use radians or degrees might be useful.  Will see when we can do something about that.

 

I'm happy to default it to degrees for now though.

Hold off revising your macros.  If it was degrees in 1.6, we'll make that the default.  I'll add the options to use Radians at a later date.
