Hi,
I have grayscale images with a white background, which I try to make Transparent (the background).
I use the Transparency tool, but it makes the whole image transparent, despite indicating the white color.
The image is in sRGB color model. I checkmark as 'Grayscale', still doesn't' work out for me.
How this should be done properly please ?
Image attached.
Thank you very much, Merry Christmas and Happy New Year!
Zal

Hi Zal,
please do the following:
1) Change to RGB with Picture/Mode/RGB
2) Use the Magic Pen and click into the white area.

Thank you so much Thorsten!
What about the two small white areas behind the rear wheels ?
The same procedure ?

Thanks!

Hi again Thorsten and very sorry for bothering,
I attached another vector graphic. I do exactly what you said to do, but few white areas on top leaves don't turn into alpha. I used the transparency tool in the tool box, adjusted tolerance, but nothing helps. These two or three white spots on the leaves that don't become alpha, can alpha be added by other means ?

Thanks!
Zal

Just use shift click into the white areas to add them.
