gradient

hey, I want to be able to have a gradient fill on the text in a UILabel I know about CGGradient but i dont know how i would use it on a UILabel's text i found this on google but i cant manage to get it to work http://silverity.livejournal.com/26436.html (Skip to bottom for full class source code) Really useful answers by both Brad Larson and Bach. The second worked for me but it requires an image to be present in advance. I wanted something more dynamic so I combined both solutions into one: draw the desired gradient on a UIImage use the UIImage to set the color pattern The result works and in

I inspired by MeBigFatGuy interesting question , in this conection I have very specific question about Graphisc2D , how to change BackGround Color by depends if is JTables Row visible in the JViewPort , 1) if 1st. & last JTables Row will be visible in the JViewPort , then BackGround would be colored to the Color.red 2) if 1st. & last JTables Row will not be visible in the JViewPort , then BackGround would be colored to the Color.whatever from SSCCE import java.awt.*; import java.awt.event.ActionEvent; import java.awt.image.BufferedImage; import javax.swing.*; import javax.swing.RepaintManager;

To state it in a general form, I'm looking for a way to join several points with a gradient color line using matplotlib , and I'm not finding it anywhere. To be more specific, I'm plotting a 2D random walk with a one color line. But, as the points have a relevant sequence, I would like to look at the plot and see where the data has moved. A gradient colored line would do the trick. Or a line with gradually changing transparency. I'm just trying to improve the vizualization of my data. Check out this beautiful image produced by the ggplot2 package of R. I'm looking for the same in matplotlib.

I often work with ggplot2 that makes gradients nice ( click here for an example ). I have a need to work in base and I think scales can be used there to create color gradients as well but I'm severely off the mark on how. The basic goal is generate a palette of n colors that ranges from x color to y color. The solution needs to work in base though. This was a starting point but there's no place to input an n. scale_colour_gradientn(colours=c("red", "blue")) I am well aware of: brewer.pal(8, "Spectral") from RColorBrewer . I'm looking more for the approach similar to how ggplot2 handles

Does anyone know the vendor prefix for gradients within IE9 or are we still supposed to still be using their proprietry filters? What I've got for the other browsers is: background-image: -moz-linear-gradient(top, #444444, #999999); /* FF3.6 */ background-image: -webkit-gradient(linear,left top,left bottom,color-stop(0, #444444),color-stop(1, #999999)); /* Saf4+, Chrome */ filter: progid:DXImageTransform.Microsoft.gradient(startColorStr='#444444', EndColorStr='#999999'); /* IE6,IE7 */ -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorStr='#444444', EndColorStr='#999999')"; /*
