Hello, everyone.
My code is like this ,I set the transparency as 90, but is doesn’t work, do somebody know how to fix this, thanks very much.
fig.grdimage(
grid=grid,
region = region,
cmap=“jet”,
projection=“M10c”,
frame=True,
transparency=90,
)

Are you using fig.show() or fig.savefig() to view the result? Does the following work to produce a semi-tranparent map for you?

import pygmt
grid = pygmt.datasets.load_earth_relief()
fig = pygmt.Figure()
fig.grdimage(grid=grid, region="d", projection="H10c", frame=True, transparency=90, cmap="geo")
fig.show()

Thanks, it’s be done.

I encountered the same problem. I used the code below, but it seems that the transparency function didn’t work. May I know how did you solve the problem? Thank you.

fig.grdimage(
    grid=grid,
    cmap="jet",
    transparency=40
    )
