How I do a relieve image ?

[dri]

Hello guys,m can you helpme please?

From this image


To this


The idea is to put the relieve over other equal images with color

try


convert 52934d34f0c97.png -alpha extract \
-shade 90x45 -fuzz 0.5% -transparent "gray(180)" \
-channel a -evaluate multiply 0.5 +channel result.png


adjust the multiply factor to give the relief more or less contrast

Thanks for your answer, but:

The effect is similar but is outside the original layer.
I need the effect inside original layer. Inside, over the white color.

How I do this?

try


convert 52934d34f0c97.png -alpha extract \
-shade 90x45 -fuzz 0.5% -transparent "gray(180)" \
-channel a -evaluate multiply 0.5 +channel result.png

Try this. Adjust the morphology erode octagon:1 value as desired to increase the erosion until it suits your requrements). If octagon:1 is too much, start with diamond:1.



convert 52934d34f0c97.png -alpha extract -morphology erode octagon:1 \
-shade 90x45 -fuzz 0.5% -transparent "gray(180)" \
-channel a -evaluate multiply 0.5 +channel result.png

It could be done with "-shadow" or more generally with "-blur". But I see the required result has white pixels with varying transparency, and transparent black elsewhere, so it's quite fiddly.

This Windows script is close to the desired result.

Code: Select all

convert ^
  52934d34f0c97.png ^
  -alpha extract ^
  -negate ^
  ( -clone 0 ^
    -blur 3x1.5 ^
  ) ^
  -geometry +0+2 ^
  -compose Lighten -composite ^
  -fill Black -opaque White ^
  -channel RGB -evaluate Multiply 0.66 ^
  -alpha Copy ^
  -channel RGB -evaluate set 100%% ^

The main difference is that the desired result has not only pure whites of varying transparency, but also dark pixels of very low transparency.

snibgo thanks for your effort, you help me a lot.

I tryed your examples and I search the combination of both :_(

The effect I need is exactly your first example, but applied over an image as the second example. The central gray color is the problem.

Like this image. The white lighting and the shadow dark, produce a good 3d effect
