GetLayerStyle()/SetLayerStyle() behaviour on AROS?

I don't know if I've missinterpreted the docs, but it looked to me that you should be able to
GetLayerStyle() on a layer to pick up all of its attributes and then
SetLayerStyle() to push them into another, essentially cloning the first later to the second. However, then I try to do this on AROS I can
GetLayerStyle() OK but when I try to put the resulting table into another layer using
SetLayerStyle() i get 'no pallette information included' or words to that effect. I've tried reading throught he table and removing any tags set to 'nil' but this hasn;t helped.
Cheers,
Nigel.

Could be a bug. Can you post an
MCVE that I can try here?

Again, many apologies for the delay in getting back to you.
To show the behaviour:
Code: Select all
; Program to test getlayerstyle and setlayerstyle
@OPTIONS {enabledebug=TRUE}
EnableLayers()
; make first shape
setfillstyle(#FILLGRADIENT,#RADIAL,#WHITE,#BLUE)
box(50,50,50,50,#BLUE,{name="box1"})
; make second shape
setfillstyle(#FILLGRADIENT,#RADIAL,#WHITE,#RED)
box(150,150,50,50,#RED,{name="box2"})
waitleftmouse()
style = {}
; get style of first
style = getlayerstyle("box1")
; set to second box
setlayerstyle("box2",style)
waitleftmouse()
The program shows two gradient filled boxes, waits for LMB press, and then ideally would copy the style of box1 to box2, except it gives the 'Image data does not have a palette" error.
Thanks,
Nigel.

Ok, I can reproduce it. Will be fixed!

Thinking about it again, it's not a bug.
GetLayerStyle() returns all kinds of additional information like "PaletteMode", "Pen", etc tags. So you can't just grab the result table from
GetLayerStyle() and inject it into
SetLayerStyle(). You have to filter out the relevant attributes and pass only those to
SetLayerStyle().
