Batch Watermarking

[Jawloms]

Hi all,

 

My wife and I have a website and we'd like to watermark all the pictures on there with our logo. We have the logo saved as a .png with a transparent background. I've tried IrfanView, but when you watermark using that it adds a colour in place of the transparency, known thing. Anyone know a batch watermarker which will handle the transparent bit of the watermark properly?

 

Thank you

 

Stuart

Nconvert seems to do it from the quick test I did.

nconvert.exe -wmfile watermark.png -out jpeg -o source.jpg wm_output.jpg

 

 

Might need to play with the other options to get it lined up:

 

-wmfile file : Watermark file (Must be after other -wm commands)

-wmpos x y : Watermark position

-wmflag flag : Watermark position

top-left, top-center, top-right

center-left, center, center-right

bottom-left, bottom-center, bottom-right

-wmopacity value : Watermark opacity (0-100)

-wmstretch : Stretch image

-wmsize value : Percent for watermark

Of course the GUI version does the same, but I forgot about it as I always use the command line version....

FastStone Image resizer (https://www.faststone.org/FSResizerDetail.htm) does this too - just to throw another converter / watermarking software. Edited October 3, 2022 by timbo343
