What is res
stand for ? resize or resolution ?
Do you ever try use extra.opts
in saveGIF()
in the animation package(development version)? It is used to add extra options of ImageMagick.
res
is the argument for resolution in png
. I have explored extra.opts
but it is for extra commands in ImageMagick call. If res
was implementd it would be in the form of ani.res
(similar to ani.width
and ani.height
), I think.
I am sorry that I cannot get your point.
Could you give me an example, what kind of problem you meet by now without res
function?
Could you mind describe the function of res
? how does it work ?
It seems that you need a resolution converter for single png picture?
res
is not a function, is an argument of png
function that controls the resolution (in ppi). For example, if you want to set the resolution of a png plot in 150ppi, you must use:
png(filename = "myFig.png", width = 1500, height = 1200, res = 150)
# Lines for my plot
dev.off()
The problem that I describe is about saveGIF does not allow (or at least I do not know the way) to modify the resolution of the plots used for building the gif.
Thank you. We will consider it.
We need improve ani.dev()
function, add resolution and customize background (issue #91)
Hello
I think that you could implement
res
argument in order to imrpove gifs which are built from png.
