I am doing a project on lossless compression algorithms. I have selected Run Length Encoding as the prefered option that is efficient with black and white images (test image is an X-ray)

I need code that will accept a bit map image and compress it using an RLE algorithm, a second algorithm can be used to turn the (now compressed) file back into a bitmap image for reading.

program 1

Must accept input of the test bitmap-106k in its uncompressed state (attached), compress it using Run Length Encoding and output a new (compressed & smaller) file

The assignment theory is that this RLE compressed file will then be emailed to another pc (hence the need for compressing AND the need to make this 2 seperate programs)-although at this stage, the RLE compressed image that is the output of program 1 DOES NOT need to be viewable.

program 2

Will then take the (compressed) output of program 1 and de-compress it back to its original state (106k)(losslessly, if the RLE alogrithm is implemented correctly). At this stage the image will now have to be readable (using standard windows image viewers).

The code will need to be well documented on an almost line by line basis, preferably with brief comments on choice of variables, etc.

Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

Complete copyrights to all work purchased.

This is required in Turbo Pascal 6.

Borland Turbo 6 compiler. The coder identified can email me direct for a 1mb copy of this compiler if they wish to be certain of compatability

Must be 100% finished and received by buyer on:
Mar 2, 2026 EDT
Deadline legal notes: All times are expressed in the time zone of the site EDT (UT - 5). If the buyer omitted a time, then the deadline is 11:59:59 PM EDT on the indicated date.

Special Conditions / Other:
Program 1 is needed for 26/03/02

Program 2 can follow the next day if necessary.

When both programs are recieved these need to be in a compilable state so I can use the attached test file to check they are doing what has been specified in the above text.

Additional Files:
This bid request includes IMPORTANT additional attached files. Please download and read fully before bidding.

I'm a professional software engineer, and have been programming for over 10 years.

I have a slight issue with your deadline. I am not available Tuesday night, but if you can escrow by Sunday night, I can have the entire project done by Monday evening. I would prefer you escrowed sooner, so I can do the project Sunday.

I can provide clean, readable, modular, documented code. Please see the remarks on my bio page for evidence of this.

I will require that you e-mail your compiler, as I only have version 7.

I do not list Pascal on my page, because I have not used it very much. I am an expert in C/C++, and am also very good with VB and x86 assembly. I have a good book on Pascal for when I do need it, and since I have coded RLE and even created my own RLE-related graphics file format, I know I can deliver your request 100%.

Thanks for the opportunity to bid on your request. I look forward to doing business with you.

P.S. If you want assurance that I can write the code in Pascal, let me know, and I will provide a sample this evening.

After thinking about it, this is rather easy. I'll only charge $50.
