----------------------------------- KukuriChan Mon Mar 15, 2004 7:41 pm Something about whatdotcolor ----------------------------------- I just want to know whether or not it is possible to use whatdotcolor with pictures. Say, for example, if you put your mouse over a red section in the picture, it'll tell you that the colour is red. ----------------------------------- Paul Mon Mar 15, 2004 7:52 pm ----------------------------------- I think so, like I tried with one of my pics: var gorilla := Pic.FileNew ("blower.bmp") Pic.Draw (gorilla, 150, 70, picMerge) var x, y, btn: int loop Mouse.Where (x, y, btn) if btn=1 then locate (1, 1)put whatdotcolor (x, y) end if end loop it told me the color of where I was clicking. ----------------------------------- Mazer Mon Mar 15, 2004 7:57 pm ----------------------------------- Yes. Somewhat. Just a few things though: first, maybe you already know but just to make sure, whatdotcolour isn't going to say 'red', it'll give you a number (probably 12 depending on the shade of red). Second, turing can draw a picture (from a file) in whatever colour mode the picture is in, but it can only 'see' in 256 colours. So if you compare turing's red with a colour that is just slightly off-red, it'll still give you 12. ----------------------------------- KukuriChan Mon Mar 15, 2004 8:03 pm ----------------------------------- Ok. I get it. Thanks! That helped a lot. But.... there's something wrong with the picture. :( There's white spots all over the place. ----------------------------------- Mazer Mon Mar 15, 2004 8:05 pm ----------------------------------- Hmm... you should explain further but my guess is you're using a JPG with a "white" background, trying maybe to draw it with picMerge. But you can't, because the JPG compression is terrible and you get lots of pixels that are off white. ----------------------------------- KukuriChan Mon Mar 15, 2004 8:10 pm ----------------------------------- I did it with picMerge. That's the only reason there's white spots all over the place. ^^ So I tried it with picXor and there's no white spots now. Thanks for the help Mazer. :)
