Hello. I encounter a strange problem when I'm writing image data to the GdkPixbuf data buffer.
I create an empty pixbuf and get the data buffer. Then I use: pixel = pixbuf_data + i * n_channels , where pixel is a pointer to the pixel, pixbuf_data is the pixbuf data buffer, i is a counter in a for loop with a condition: for (i = 0; i < width*height; i++) This for loop should iterate throught all pixel in the image. The n_channels variable is 4 because I use a RGBA pixbuf. When I have this pixel pointer, I use pixel[0], pixel[1], pixel[2] and pixel[3] to modify the RGBA values. I then handle the "expose-event", create a cairo surface using the GdkPixbuf and display the surface onto the drawing area. The problem is when I display the pixbuf the image is shifted to the right for exacly two pixels. Meaning the first two pixels in the upper left are two places to the right, making the last two pixels of the row appear in the second row. I hope you understand. Am I making something wrong when writing data to the pixbuf? Or is there any other explanation. Please help. Greets, Luka
