How to convert 24 bit image to 8 bit

It is easy to download a software which converts the 24 bit image to 8 bit image. The software is based on digital image processing algorithms, which gives you exactly what your want. You also can use MS-office Picture manager to edit the image file, but in this your have to do a lot of work and make assumptions use the menu command Image->Type->8 bit, to convert the image to 8 bit grayscale, then use the menu command Save as->Jpeg to select what to name it and where to put it. If you want to do this for many files, ImageJ provides a macro recording feature so you can record the steps to automate this procedure. 12.7K view The way you described it though, getting 8 bpp out of 24 bpp is pretty straightforward - you would need to strip least significant bits and merge the bits into single byte value, per pixel. AFAIK it is not a standard or well-known pixel color representation To save an image in Photoshop as an 8bit Bitmap image you need to change the Image->Mode to Grayscale then you can save as 8 or 4 bit image. //edit. In Photoshop go to Image->Mode->Indexed Color. Set the Palette to Exact, System (Mac OS), System (Windows), or any of the Local settings making sure the Colors says 256

Can anyone tell how to avoid this problem? · Hi Milind Kalal, I found some code in the Internet which can convert an image to 8 or 1 bpp, please check the code snippet below.
  3. Re: Conversion from 24 bit bitmap to 8 bit. You may use the following macros to set a 24bit bitmap pixel to a desired value, which are quite fast, but don't check for valid pointer; or you can use the followeing function, which return a pointer to the requested pixel, simply replace width and height with your values and bit count with 24
  4. There's no such thing as a 24 bit depth image really in general usage. Each channel is 8 bits so any RGB image that's 8 bit would be... Red 8 bits + Green 8 bits + Blue 8 bits = 24 bits. So if you're image is at 16 bit RGB say a raw file, just convert it to 8 bit RGB
  5. To convert 24 bit color to 8 bit color you must consider that 255 should be converted to 7, so the formula should be Red3 = Red8 * 7 / 255 8bit Color = (Red * 7 / 255) << 5 + (Green * 7 / 255) << 2 + (Blue * 3 / 255) With your example color #c0c0c0 would lead to a wrong 8 bit RGB. Test it with this link
  6. Converting 8-Bit Image to 24-bit Image. QUESTION: I have an 8-bit color image bitmap file that I read like this: bmp = READ_BMP(filename, r, g, b) The bmp variable is an N x M array with values that are indices of the RGB arrays.For example, if bmp[5,10] = 3, the color triple for that pixel is R[3], G[3], B[3].To convert this to an N x M x 3 array so I can use it on a button widget, I've used.
