I'm trying to automatize bulk fourier watermarking using the comand line version of G'MIC, but I have trouble when trying to read the watermark.
Looking thru the examples, I tried this one:
image.jpg --watermark_fourier "Watermarked!" --display_fft -remove[-3,-1] -normalize 0,255 -append[-4,-2] y -append[-2,-1] y
That results four images, the fourth one with the watermark clearly visible.
Then this is the code I tried:
gmic -input image.jpg -watermark_fourier watermark_text -output image_WM.jpg
And the code to get the wartermark:
gmic -input image_WM.jpg -display_fft -normalize 0,255 -output image_SW.jpg
But when done this way, the watermark is barely visible, and I don't know why doesn't work like the example.
I'm using the 64 bit Windows 1.7.9 version.
