Thread: How To Incorporate input_byte In For Loop Query ?

I have the following part of a C# Code :-

Code:

while(current_input_position <= input_max_valid_position) {

                input_byte = input_data[current_input_position];
                current_input_position++;


                for (int i = 0xFF; i >= 0x00; --i)


                    if (input_byte == 0xFF) {
                    //==============
                    // Fin de chunk
                    //==============
                    Save();
                    current_output_index++;


                    RLE_sumador            = 0;
                    line_min_length        = int.MaxValue;
                    line_max_length        = 0;
                    width_current        = 0;
                    image_height        = 0;


                } else if(input_byte == 0xFF) {
                    //=================
                    // Siguiente linea
                    //=================
                    if(width_current < line_min_length) line_min_length = width_current;
                    if(width_current > line_max_length) line_max_length = width_current;


                    if(forced_image_width!=null) {
                        count = forced_image_width.Value - width_current;
                        if(count > 0) {
                            for(n=0; n<count; n++) {
                                output_buffer.Add(0);
                            }
                        }
                    }


                    image_height++;
                    width_current = 0;

I am adapting a Code to try to brute force all combinations of input_byte combinations, going backwards from 0xFF to 0x00, if possible I would like to exclude, all combinations of Hex Values for input_byte being numbers i.e 00 01 02 etc, as these will never produce Bitmaps.There are five input_byte == blocks of Code I have typed each one as 0xFF as that is the Hex Value, where the For Loop starts from. When I use --i in the for loop line of code, it runs for a few seconds, so not working for me.

I tried --input_byte instead however it just runs and runs, and I know it isn't trying out all combinations of input_byte, as in the attached image, to this Thread, the number in the () stays at 636, the numbers should be a variety.

The Program extracts images, from a DOS Games Graphics Files, and saves them as Greyscale Bitmap Files. I could provide more Code if needed, input_byte is declared as a byte higher up in the Code. Is the for loop in the wrong place ? How do I incorporate, input_byte, in the for loop ?

Any help would be much appreciated.
