Yes you can do this. The JPEG format makes provision for exchangeable image file format Color space definition Component sub-sampling registration Pixel aspect ratio definition JPEG/Exif is the most common for photography and JPEG/JFIF is the most commonly used for storage. When the others state JPEG format doesn’t provide for an alpha channel all they … Read more
I was able to achieve something like this in pure xaml using a Brush to paint the main grids background. This way only parent grid will have its opacity set and its child elements won’t inherit it. <Grid x:Name=”LayoutRoot”> <Grid> <Grid.Background> <SolidColorBrush Color=”Black” Opacity=”0.5″/> </Grid.Background> <Grid.RowDefinitions> <RowDefinition Height=”0.333*”/> <RowDefinition Height=”0.333*”/> <RowDefinition Height=”0.333*”/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition … Read more
Yes for the colors, use rgba(x, y, z, o) where o is the opacity should work e.g. background-image: -webkit-gradient(linear, left top, left bottom, from(rgba(255, 255, 255, 1)), to(rgba(0, 0, 0, 0))); Edit: For the final value (opacity) 1 is opaque & 0 is transparent
Ok, so what we can do is create a :after element that will be equal to the size of the parent. Using this we can set a background gradient that will make it appear as the image is fading into the solid colour background. Note: In this example I have made the gradient element a … Read more
As far as I know, opacity or other color filters can’t be set on the Bitmap itself. You will need to set the alpha when you use the image: If you’re using ImageView, there is ImageView.setAlpha(). If you’re using a Canvas, then you need to use Paint.setAlpha(): Paint paint = new Paint(); paint.setAlpha(100); canvas.drawBitmap(bitmap, src, … Read more
SUMMARY: Depending on what is needed it can be tricky but the basic approach is pretty straight forward. This approach is a little different from my first thought… but this has the same result. I made a black/transparent pattern for the circle and set it to :before. The circle is then transformed rotate(180deg) and moved … Read more
You can use the background-color: rgba() notation: #theIdofYourElement, .classOfElements { background-color: #fff; background-color: rgba(255,255,255,0.5); } Edited to add the default background-color (for browsers that don’t understand the rgba() notation). Albeit I was under the impression that all but IE do understand it (but I could be wrong, and haven’t tested to be sure…). Edit with … Read more
I’ve never seen that as “overriding” or “underriding”. It’s a matter of relative opacities. If the parent has an opacity of 0.5, the child has it too (in relation to the parent’s stacking context). The child can have its own opacity value between 0 and 1, but it will always be relative to the parent’s … Read more
Yes, but specify color in rgba mode to add alpha transparency. h1.blue {text-shadow: 3px 3px 0px rgba(63,107,169, 0.5)} //half of transparency
