Make image transparent in ruby -

-

I was thinking that someone could suggest potential libraries in ruby ​​to manipulate jpegs? Especially I want to make the image 50% transparent, so that it can act as an overlay. The image in question will be of a house and I would like it to overlay the image of a village.

Variations may not be liked by many colors due to just being specific about the image.

. It features transparency / opacity.

Good luck,
Fabian

I have a list of agents, which has been thrown at B13: B23 and the next two, I have columns of data that assume that my data base looks like this bcdx | Y Z Agent 1 1 | 1 | 0 Agent 2 0 | 1 | 0 Agent 3 0 | 1 | 1 agent 4 1 | 0 | 0 ...
