I want to get the color of one pixel of screen
View 2 Replies View RelatedI have some png files that I am applying a color to. The color changes depending on a user selection. I change the color via 3 RGB values set from another method. The png files are a random shape with full transparency outside the shape. I don't want to modify the transparency, only the RGB value. Currently, I'm setting the RGB values pixel by pixel (see code below).I've come to realize this is incredibly slow and possibly just not efficient enough do in an application. Is there a better way I could do this? Here is what I am currently doing. You can see that the pixel array is enormous for an image that takes up a decent part of the screen
View 1 Replies View RelatedI'm being confused by the 'screen density' concept in Android. I knwe that dpi (dot per inch) came from the printing device. 160 dpi means 160 dots in every inch on the paper. However, when dpi is used for the screen density, for example, what's mentioned '160 dpi screen' in Android document, what's the meaning? 160 pixels on every inch of the display?
As described in http://code.google.com/intl/zh-CN/android/reference/available-resourc..., 1 dip (density-independent pixel) means 1 pixel on a 160 dpi screen. Why does the ratio of dp-to-pixel not necessarily change with the screen density in direct proportion?
When the dpi is changed from 160 to 80, how many pixels will 1dp will take? 0.5?
I can hardly understand why dip/dp is introduced into Android.
Before I submit this I just wanted to check it's not a java nuiance.
The Color class can be used to extract rgb values from a pixel (32 bit int).
I implemented a lookup table filter and used a byte to store each individual r g & b value to save a bit of space.
Long story short;
CODE:...........
137 is the magic number causing the error in my case, there may be more.

View 4 Replies View RelatedWhen I develop an Android map application, I want to draw a circle on the map whose radius is 1 meter. As you known, I can't draw 1 meter directly, I should convert 1 meter to the distance of two pixels depend on the zoom level. How to I convert it, is there anything API I can use.
Canvas.draw(x, y, radius), what value should I put to this method ?
I need to know how many pixels wide and tall the screen is. I know that there are a bunch of different localization folders that I could make for different views but I just need to know, programmatically, how many pixels are on the screen so I can do some drawing. How can I detect this?
View 4 Replies View RelatedA lot of hay is being made over the iPhone4's 326 ppi screen density. I was just curious, for comparison purposes, what's the pixel density of the Evo screen? This would be an easy calculation to do if I knew what the horizontal and vertical dimensions of the screen were, but I can't seem to find that information anywhere.
If anyone knows the pixel density or even just the exact X and Y dimensions of the screen..
Noticed a single stuck red pixel on my screen... was so excited about the phone that I didn't wanna return it and have to wait a few days for a replacement since all the radioshacks around my area are sold out.
View 24 Replies View Relatednote: this is an artist rendition because my digital camera is terrible and i couldn't figure out how to get the dust in the shot. but it looks just like this. it's a black speck under the screen that can only be seen on bright surfaces and only if you are looking at the screen head on. i'm not sure if it might be a dead pixel. i can certainly live with this problem although i'd prefer if it wasn't there.
1. is this a dead pixel or dust?
2. how do i fix this, can i just exchange it at the vzw store whenever they stop being sold out?
I've had a HTC Evo now for 2/3 weeks, and I love it! But over the last few days it's started to act funny....
What it's doing is lets say I unlock the phone and have it laying on my desk, in the past it would show the screen in portrait orientation....but over the lat 2/3 days its been jumping to landscape and I have to pick up the phone, tilt it to get it back to portrait, and if I lay it back down it will go back to landscape.
This is mainly annoying when checking emails/texts/etc, but also if I am on the train and holding it near my waste, depending on the angle it will bounce back and forth from portrait to landscape!
I originally did a reformat when I bought it, and I am going to do it again shortly to see if that helps....just wondering if anyone else had this problem and if it's fixable (and yes i do want auto rotation)....
My phone has a few other problems such as minor light leakage, and a dead pixel (which I was going to look past and keep the phone)...so if this is something wrong with the hardware it would be a pretty good reason to get a replacement within my 30 days....
Is there an app that will randomly change your home screen and wallpaper to a different one at some pre-determined interval, say every time the phone restarts? There are so many cool looking home screens and wallpapers that I can't make up my mind. It would be nice to select a bunch and then have them randomly selected every restart or specified interval, kind of like shuffle on a CD player.
