tint

I am working of new Android L preview and now dealing with tinting concept on drawable. I want to know if there is anything new regarding drawable tinting in Android L Developer Preview. I read this this documentation which says: The Android L Developer Preview enables you to define bitmaps or nine-patches as alpha masks and to tint them using a color resource or a theme attribute that resolves to a color resource (for example, ?android:attr/colorPrimary ). You can create these assets only once and color them automatically to match your theme. But I didn't understand how it is different from

So I have seen quite a few ways to darken images with CSS, including ones with rounded corners, but my problem is different. Let's say I have an .png image that looks like a little dog (just go with it, I don't have any good examples), when I place it on my page, I give it dimensions of 100 x 100. But I can't just overlay something on it, or tint the entire image, as it will cause the background of the dog to be tinted as well, which looks ugly. Is it possible to tint an image of arbitrary shape with CSS? (I'm assuming you understand my point, and useless code is not necessary) Thanks! You

just switched to iOS 4 on my iPhone 3GS and some of my apps broke. One issue I had is that I had a UIToolbar with some buttons, tinted to pink, that worked well on the 3.1.3 OS. After upgrading to iOS 4, the toolbar was still tinted, but the buttons it contained were no longer affected by the tint. The toolbar was pink while the buttons were regular-blue. Looked around for it on the net, but found no reference of such a thing. Anyone knows what broke in the process? (must be frank here - I knew the answer before posting, just didn't know how to load this data to StackOverflow. Thought the

I searched everywhere but didn't find the solution. I have image 1. How can I programatically tint them with gradient to get images 2 and 3? Here are those images: Tints that I applied to them via Photoshop are simple 2-color linear gradients. And my question is: how can I achieve this effect programatically? Solution: jrtc27 gave me almost working example. I fixed it (for ARC) and made it reusable (using UIImage's category). Here is it: - (UIImage *)tintedWithLinearGradientColors:(NSArray *)colorsArr { CGFloat scale = self.scale; UIGraphicsBeginImageContext(CGSizeMake(self.size.width * scale,

I'm trying to tint an image prior to Android API level 21. I've successfully tinted items using: <android:tint="@color/red"/> However, I can't seem to figure out how to do this through code on an ImageView: Drawable iconDrawable = this.mContext.getResources().getDrawable(R.drawable.somedrawable); DrawableCompat.setTint(iconDrawable, this.mContext.getResources().getColor(R.color.red)); imageView.setImageDrawable(iconDrawable); I've tried setting the TintMode but this seems to make no different. Am I using the v4 compatibility class DrawableCompat incorrectly? The simplest way to tint cross

I know it's possible to tint a rectangular image by drawing a CGContextFillRect over it and setting the blend mode. However, I can't figure out how to do a tint on a transparent image such as an icon. It must be possible since the SDK does it itself on tab-bars in such. Would anyone be able to provide a snippet? UPDATE: Lots of great suggestions have been given for this problem since I originally asked. Be sure to read through all the answers to figure out what suits you best. UPDATE (Apr 30, 2015): With iOS 7.0, I can now just do the following, which would satisfy the needs of my original
