Here’s code making use of Pillow and Scipy’s cluster package. For simplicity I’ve hardcoded the filename as “image.jpg”. Resizing the image is for speed: if you don’t mind the wait, comment out the resize call. When run on this sample image, it usually says the dominant colour is #d8c865, which corresponds roughly to the bright … Read more
In styles.xml <style name=”itemTextStyle.AppTheme” parent=”@android:style/TextAppearance.Widget.IconMenu.Item”> <item name=”android:textColor”>@drawable/color_item_popup</item> <item name=”android:textSize”>@dimen/text_content</item> </style> and add in AppTheme <item name=”android:itemTextAppearance”>@style/itemTextStyle.AppTheme</item> color_item_popup.xml <selector xmlns:android=”http://schemas.android.com/apk/res/android”> <item android:state_pressed=”true” android:color=”@color/primary_text”/> <item android:state_focused=”true” android:color=”@color/primary_text”/> <item android:color=”@color/secondary_text”/> </selector>
Convert the RGB values to the range 0-1, this can be done by dividing the value by 255 for 8-bit color depth (r,g,b – are given values): R = r / 255 = 0.09 G = g / 255 = 0.38 B = b / 255 = 0.46 Find the minimum and maximum values of … Read more
It just so happens I needed this function for a project not long ago. private int PerceivedBrightness(Color c) { return (int)Math.Sqrt( c.R * c.R * .241 + c.G * c.G * .691 + c.B * c.B * .068); } This formula I found on the web at Nbd Tech that dealt with perceived colors and … Read more
The RGB int color contains the Red, Green, Blue components of the color in its bits. You have to look at its binary or hexadecimal representation and not look at it as a whole integer number (not look at its decimal representation). An int has 32 bits, 3×8 = 24 is used to store the … Read more
For Bootstrap 3 this is how I did this based on the default Navbar structure: .navbar-default .navbar-nav > li > a:hover, .navbar-default .navbar-nav > li > a:focus { background-color: #FFFF00; color: #FFC0CB; }
Hex values are easier to copy and paste from your favourite image editor. RGB values are easier to manipulate with Javascript. (My favourite Hex colour value is #EDEDED and a site we made for a client involved in motorsport had a background colour of #F1F1F1 🙂 Ed.
If you want the default colors of Android ICS, you just have to go to your Android SDK and look for this path: platforms\android-15\data\res\values\colors.xml. Here you go: <!– For holo theme –> <drawable name=”screen_background_holo_light”>#fff3f3f3</drawable> <drawable name=”screen_background_holo_dark”>#ff000000</drawable> <color name=”background_holo_dark”>#ff000000</color> <color name=”background_holo_light”>#fff3f3f3</color> <color name=”bright_foreground_holo_dark”>@android:color/background_holo_light</color> <color name=”bright_foreground_holo_light”>@android:color/background_holo_dark</color> <color name=”bright_foreground_disabled_holo_dark”>#ff4c4c4c</color> <color name=”bright_foreground_disabled_holo_light”>#ffb2b2b2</color> <color name=”bright_foreground_inverse_holo_dark”>@android:color/bright_foreground_holo_light</color> <color name=”bright_foreground_inverse_holo_light”>@android:color/bright_foreground_holo_dark</color> <color name=”dim_foreground_holo_dark”>#bebebe</color> <color … Read more
This will help much no need to do so much coding 🙂 ProgressBar spinner = new android.widget.ProgressBar( context, null, android.R.attr.progressBarStyle); spinner.getIndeterminateDrawable().setColorFilter(0xFFFF0000,android.graphics.PorterDuff.Mode.MULTIPLY);
