i'd tried to make image from the given file name.but i failed.. can you tell me how to do it. i use this as my code fc = new FileChooser("image", "Open"); _fnSrcCom = fc.getFileName(); Image pic = Toolkit.getDefaultToolkit().createImage(_fnSrcCom); int width=pic.getWidth(null); int height=pic.getHeight(null); int Size = width * height; i get width = 240 height=-1 and size = -240 the original width of the image is 180x240

could any one tell me how to do zigzag scanning in java. i was doing it in c++ i was use this in c# struct zigzag { int row; int col; } ZigZag[8*8] = { {0,0}, {0,1},{1,0}, {2,0},{1,1},{0,2}, {0,3},{1,2},{2,1},{3,0}, {4,0},{3,1},{2,2},{1,3},{0,4}, {0,5},{1,4},{2,3},{3,2},{4,1},{5,0}, {6,0},{5,1},{4,2},{3,3},{2,4},{1,5},{0,6}, {0,7},{1,6},{2,5},{3,4},{4,3},{5,2},{6,1},{7,0}, {7,1},{6,2},{5,3},{4,4},{3,5},{2,6},{1,7}, {2,7},{3,6},{4,5},{5,4},{6,3},{7,2}, {7,3},{6,4},{5,5},{4,6},{3,7}, {4,7},{5,6},{6,5},{7,4}, {7,5},{6,6},{5,7}, {6,7},{7,6}, {7} } i use this in java.. //the initiation protected int zigzag[][] = { {0, 1, 5, 6,14,15,27,28}, {2, 4, 7,13,16,26,29,42}, {3, 8,12,17,25,30,41,43}, {9,11,18,24,31,40,44,53}, {10,19,23,32,39,45,52,54}, {20,22,33,38,46,51,55,60}, {21,34,37,47,50,56,59,61}, {35,36,48,49,57,58,62,63}, }; //the method public void zigZagScan(int blkIn[][],int buffOut[]) /* Desk: Method for zigzag scanning as a pattern of scanning in RLE I.S : array 2D of 8x8 F.S : array 1D of 64 */ { int row, col; for (i=0;i<64 ;i++ ) { row = zigzag[i]; //i want to use row = zigzag[i].row col = zigzag[i]; //i want to use col = zigzag[i].col buffOut[i]=blkIn[row][col]; } } could any one tell me what is the suitable sintax in java? thanx

Dear all, i'm in a middle of a thesis.and i have some problem in getting the frame in video structure, so i can get it as an image. can any body help me how to do it in java? Thanx :)

Can any body tells me how to make a video player in java? :((

hello guys, i'd like to make a video compression with java, but i don't know how to get the pixel value in java for the DCT input:confused:. could any one help me? thanks.GBU

Dear partners, i'm a newbie programmer in c# environment. Can you help me how to get the pixel value in colored image in c#? thx.GBU :-D Best Regards,

i have a question about DCT..actually it's sound like silly question but it's important for me.. The question is: 1. Why on DCT the function use a cosine function, if we see on the image and the function there is no connection with angle. 2. Why the function using cosine, why not using sine or tangen? what is the influence for the compression ratio?. 3. Is it true that we using the pixel depth for making 8x8 matix as the input for DCT, if it's true how to get a pixel depth on image in C# so we could make the 8x8 matrix. thanks.. God bless you
