java,image,colors,background,pixel
What you have is almost correct. Simply read in your second picture like you have your first picture here: Picture background = new Picture("background.png"); background.explore(); Then in your inner loop simply do: targetPixel = pictureObj2.getPixel(x,y); pixelColor = targetPixel.getColor(); if(!pixelColor.equals(WHITE)) //test if you have a blank pixel background.getPixel(x,y).setColor(pixelColor); //if not its...
Problems with changing colors in chart winform
c#,winforms,charts,colors,series
The colors are assigned automatically according to a palette, unless a color has been set explicitly. So the next series down gets the freed up color. To avoid this, you need to explicitly set the colors of all series. See http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.series.palette(v=vs.110).aspx...

Messed up color scheme in ReSharper C++
c++,visual-studio-2013,colors,resharper,resharper-c++
The colour scheme is not really messed up, Resharper has just added a few more colours, this is probably due to the Code Inspections (for C# anyway, I assume it is similar for C++). To disable this, go to: Resharper->Options...->Code Inspection->Settings and uncheck the 'Color identifiers' EDIT: The above was...
gstreamer wrong colors when converting h264 to raw RGB
linux,colors,rgb,gstreamer,gst
As noted in the comments below: the "-q" option is needed to prevent gst-launch from spitting out debug info to the stdout pipe. Ok, funny story, looks like when you specify video size in ffplay you use HEIGHTxWIDTH, and in GStreamer you use WIDTHxHEIGHT. This command works fine: gst-launch-1.0 -q...

As far as I am currently aware, the only way that you'd be able to do this is if you were to create a custom driver that can act as an intermediary between the user. I haven't read much of it, but you might want to look into this project...

kivy: press button -> change color of a label
python,canvas,colors,label,kivy
The easiest way is to use an intermediary property from kivy.properties import ListProperty class ColourLabel(Label): ellipse_colour = ListProperty([1, 0, 0, 1]) Then in the kv <ColourLabel>: canvas.before: Color: rgba: self.ellipse_colour Ellipse: size: self.size pos: self.pos Note that I added the pos to Ellipse, which is presumably necessary in general. You...
Matlab plot3 movie where the colour of each point varies depending on arbitrary vector
A possible solution could be: to define a matrix of colour indeces: since you need 9 colours it should be a (9 x 3) matrix to use the value stored in the 5th column of your data to select the color in the color matrix (i. e. to select the...
C++ game color needed
I found parts of this code on the internet, and parts of it I wrote myself. I made a class named Colour and overloaded the operator<<. The code is as below: #ifndef COLOUR_H #define COLOUR_H #include <iostream> #include <windows.h> inline void SetColour (WORD val) { SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), val); } class Colour...
