Make transparent for watermark


Recommended Posts

If you want to get rid of the white, [sHIFT] + Magic Wand -> [DELETE] should do it for you. If you mean make the image itself transparent, put it on a new layer above all other layers, and turn the layer's opacity down to about 50.

That isn't the exact solution...

There is a way to put an invisible watermark on it, if it is being posted on the web, so people don't steal it...Not just blending it in, but so you can only see it when the image is highlighted....It is wierd, If I remember how to do it, I will write a tutorial on it.

Trickman, way to be critical without being helpful...His idea sounded fine to me. I guess it just matters what you need it to look like.

Sorry, I was in a rush

There's something in GIMP called Color2Alpha, which for example, if you had a grey pixel and you wanted white to be alpha, then the grey pixel would turn black with transparency.

On-Topic: If you want to do a watermark probably the best solution would be to simply shrink the pic to whatever size you want it to be, stick it on a new layer, and adjust the transparency.

off-topic - trickman: I think color to alpha takes the intensity of the color and converts it to alpha but the rgb values stay the same. but like, if you had gray selected, gray would be completely transparent (or opaque, haven't used gimp in a while) and then the alpha value would drop off based on the intensity of gray in all other selected pixels.

The perfect antialiased watermark technique:

Copy the image into paintshop.

Greyscale.

Create a new source luminance with inverted data mask from image.

Fill the image with all black.

Load the selection from the mask.

Copy and paste into a new image.

The result (enlarged 200%):

Then just place on some image in a layer with 25% opacity:

That isn't the exact solution either... Color2Alpha, my friend, Color2Alpha.

actually, I forgot to say that PdN has something quite close to color2alpha, which is called, "Multiply" blending mode. Put the logo in a separate layer then change it to multiply and it is almost the same to color2alpha (The effect is the same, though it only works when there are 2 layers with some stuff other than transparency)

This is actually quite easy in Paint.NET.

Part #1

1. Open image and import seal (watermark) into new layer.

2. Position seal by selecting it in the image and moving to desired loaction.

3. Set Blending mode of seal Layer to multiply and adjust transparency(just like Trick man suggested).

Part #2 (for sysrpl's effect)

1. Open image and import seal (watermark) into new layer.

2. Position seal by selecting it in the image and moving to desired loaction.

3. Invert colors on seal layer.

4. Set Blending mode of seal Layer to Additive and adjust transparency.

See, easy as pie.
