Transparent watermark

Matt666

Hi all !
I have a style by default that contains a logo and some text. I want this logo to have just white color transparent, because it is above the drawing.

I tried to make white color of this logo transparent, save as PNG, and inserted in the drawing. I placed it above the model space, but white color is displayed! No transparency... And I can't use blend method, because logo must be clarly readable!

Can you help me, please?
Thank you!

I dont suppose you could make the model background white? Then it would all blend together...

Was the logo saved as an Interlaced PNG.?

Thank you for your quick answers!
Model Background is already white, remus.
Here is the logo: Sans titre 2.jpg But model is above him. So you don't see logo all the time.
Sans titre 3.jpg And when I try to put logo above model space, white color of the logo is displayed:
Sans titre 4.jpg i want logo above model space but without white color... Like this:
Sans titre 5.jpg

I don't know... I don't understand all PNG parameters

Thank you!

Can you post the logo image you are using?

Matt666

Yep! Thank you for your interest Thomthom!
EDIT : What is this f*****g black color????

thomthom

That blackness you see in that thumbnail is due to the thumbnail generator not handling transparency in the original image.

I'll look at your image now.

I found the cause of the transparency problem.
SU doesn't like transparency in images with a palette. When I converted your image to be full-colour image the transparency worked fine.

Attached is the image that works.

Wow thank you thomthom! I don't understand how you do that, but it works fine!

Sorry... I don't like transparency

Your image had reduces number of colours. An palette of 256 colours. All I did was open it up on Photoshop and set it to full colours. (16.7 millions) Image->Mode->RGB Color. You will see that your original image has I ndexed Color ticked when you open it up in Photoshop. That indicates it has reduced number of colours.
