BUT, at run time when i click the button to do it, it doesnt give me any error messages or anything. the code i have is below: MatchCollection lines = Regex.Matches(File.ReadAllText(Path), @"(.+?)\r\n""([^...
hi, i am reading a 24bpp bitmap , and i need to convert each pixel from RGB24 to ARGB16. i am using this : #define ARGB16(a, r, g, b) ( ((a) << 15) | (r)|((g)<<5)|((b)<<10)) but the output it's not what i need, can someone offer some help ? thank you. ...
the R and B gets error when using this logic, i cant seem to find what im doing wrong, my workaround in the end were i flip the r and b is not good at all and im trying to find where the logic breakes. the label1.Text = colorX; shows R=255, G=0, B=0 when it shold be R=0, G=0, B=255, where does this fail? using System; using System.Coll...
i'm studying getPixel32() and the Bitmap and Bitmap Data classes. Basically, i'd like to know how to output a simple trace of an ARGB from a hexadecimal value. as an aside, i'm under the impression, which i assume/hope is wrong, that hexadecimal values can't produce as many colors as RGBA values. perhaps "web safe" has thrown me off...
Good day everyone, I am stuck trying to convert a uint color value into its equivalent argb hexadecimal format. Basically, I am trying to convert a color from Flex(AS3) into its appropriate kml color, which is in the argb hexadecimal format from what I gather. Below is my function as it stands now. Although it does convert into a val...
How would I go about converting the pixels in an image (.png file) to an integer array, where each pixel is converted to its ARGB integer equivalent? Not a 2D integer array by the way, a 1D one (where access is through array[row*width+col]). Thanks. ...
I am trying to use the MakeColor method in the GDIPAPI unit but the conversion from int to byte is not returning me the correct value. Example var argbStr: string; A, R, G, B: Byte; begin argbStr := 'ffffcc88'; A := StrToInt('$' + Copy(AValue, 1, 2)); R := StrToInt('$' + Copy(AValue, 3, 2)); G := StrToInt('$' + ...
Hello -- System.Drawing.Color has a ToArgb() method to return the Int representation of the color. In Silverlight, I think we have to use System.Windows.Media.Color. It has A, R, G, B members, but no method to return a single value. How can I implement ToArgb()? In System.Drawing.Color, ToArgb() consists of return (int) this.Value; ...
I try to read an image from sdcard (in emulator) and then create a Bitmap image with the BitmapFactory.decodeByteArray method. I set the options: options.inPrefferedConfig = Bitmap.Config.ARGB_8888 options.inDither = false Then I extract the pixels into a ByteBuffer. ByteBuffer buffer = ByteBuffer.allocateDirect(width*heigh...
I'm currently using something like: TextView.SetBackgroundColor(Color.WHITE); in my java code. I'd like to be able to add some transparancy to the textview through the java... This is easy to do in the XML via #AARRGGBB format, but I have not found a way to accomplish this programmatically. ...
Hello, I'm quite new to C# and trying to do a basic image processing software. I understand this snippet extracts A,R,G,B from an ARGB int value of a WriteableBitmap pixel "current" for(int i = 0; i < bitmapArray.Length; i++) { var current = bitmapArray[i]; var alpha = (byte)(current >> 24); var red = (byte)(current >> 16)...
I'm currently working on an image editor in Flash Player, and I need to be able to export CMYK images to my server. I'm completely new to color profiles and the like, and I was wondering how I could accomplish this. I am pretty sure all images in Flash Player are ARGB, so is there a way to convert the values properly? ...
Hi, I'm trying to create a X11 window with a bit depth of 32 so that I can use ARGB colors. Here's what I do: XVisualInfo vinfo; int depth = 32; XMatchVisualInfo(dpy, XDefaultScreen(dpy), depth, TrueColor, XCreateWindow(dpy, XDefaultRootWindow(dpy), 0, 0, 150, 100, 0, depth, InputOutput, vinfo.visual, 0, NULL); Here's what happe...
Hi, Im using glReadPixels to grab screen shots of my opengl scene and then turning them into a video using AVAssetWriter on IOS 4. My problem is i need to pass the alpha channel to the video which only accepts kCVPixelFormatType_32ARGB and glReadPixels on retrieves RGBA. So basically i need a way to convert my RGBA to ARGB, in other wor...
