Record by record transparency has been added to plot
at #626, and also plot3d
at #471, so what's left is just adding it to text
?
On a side note, we might want to add a test for grdimage
with transparency. I'm getting this error on PyGMT
v0.2.1, GMT
6.2.0_92c5676_2020.11.10 with ghostscript
9.53.3:
fig = pygmt.Figure()
fig.grdimage(grid="@earth_relief_01d", transparency=70)
fig.show()

Will submit a proper bug report once I can isolate the issue.

Yes, I think I already have a local branch for the text
transparency. Will check if it works as expected and submit it later.

Great! No rush though, I was just searching for transparency examples and saw this issue was still open

Yeah, I might need to update my GMT dev version, can't reproduce this on try-gmt
either :/ Maybe https://github.com/GenericMappingTools/gmt/pull/4464 fixed this.
Description of the desired feature
614 added the
transparency
argument to all plotting functions. In most functions,transparency
can be an int/float value in 0-100. For a few functions (plot, plot3d and text), transparency can be a list to have varying transparency for symbols and texts.We should extend these functions to support the varying transparency feature.
Are you willing to help implement and maintain this feature? Yes
