- LEADTOOLS DEMO is for Evaluation purposes only. Your license to use this
- software will expire after 3 weeks from the date you receive it. You are
- free to distribute this demo copy of LEADTOOLS as long as all files
- listed below are all included. You may not distribute any of the files
- separately.
-
- The demo program contains four (4) .EXE files which demonstrates some of the
- functions that are included with LEADTOOLS DOS. The demo program is designed
- to give you a working understanding of LEAD Technologies' image processing
- capabilities, and how the image processing functions may be incorporated
- in your application.
-
- This diskette contains the following files:
-
- README.1st The file you are currently reading.
-
- DEMO.C The source code of the demo.EXE file.
-
- DEMO.EXE Simple demo program that calls the most commenly used functions
- in one EXE. DEMO.C compiled and linked with LEADTOOLS "C"
- run-time library for VGA/SVGA/TARGA+16-64.
- LEADTOOLS also has a library for the old TARGA16-32 but this EXE
- was linked with the TARGA+16-64 familly. You must have a
- SuperVGA with 640X480X256 colors to run this program.
-
- LSHOW.C The source code of LSHOW.EXE.
-
- LSHOW.EXE DOS file to screen software decompression utility compiled
- and linked with LEADTOOLS "C" run-time library. The Show
- program has not been linked with all the libraries. LSHOW
- supports over 130 graphics cards including the Serria RAM DAC
- versions of the ET4000, Trident, and ATI XL. Truevision
- TARGA+16-64 Graphics cards are supported, (8 bit 256 color,
- 16 bit 32,000 color, and 24 and 32 bit 16,777,000 color). To
- save disk space we did not include the old TARGA16-32 only
- TARGA+16-64. Run the program by itself to get the help screen.
-
- SCF2f.C The source code of SCF2F.EXE.
-
- SCF2S.EXE DOS file to file software compression utility compiled
- and linked with LEADTOOLS "C" run-time library. Run the
- program by itself to get the help screen.
-
- SDF2F.C The source code of SDF2F.EXE.
-
- SDF2F.EXE DOS file to file software decompression utility compiled
- and linked with LEADTOOLS "C" run-time library. Run the
- program by itself to get the help screen.
-
-
- Q factor settings.
- -----------------
- Typing in a factor of 2 to 255 will alter the Q factor and
- therefore change the image file size and the image quality. A
- factor of 2 will produce the best image quality and the largest
- file size, while a factor of 255 will produce the smallest file
- size and lowest image quality.
-
- LEAD also has defined several Q factor settings at breaks
- between the size vs. quality trade off. The selections are
- given in abbreviated form in the EXE program. The abbreviations
- represent the following:
- PQ1 - Perfect Quality Option1
- PQ2 - Perfect Quality Option2
- QFS - Quality is far more important than size.
- QMS - Quality is more important than size.
- QS - Quality and size are equally important.
- SQS - Size is more important than quality (sharp - images
- with sharp contrasts in color or content, or with text).
- SQT - Size is more important than quality (less tiling - for
- images with a lot of the same color tones, such as
- portraits).
- MCQ - Maximum compression with quality still important.
- MC - Maximum compression.
-
- Technical Notes
- ---------------
- All included .EXE programs are not designed as end user products. They are a
- collection of calls to LEADTOOLS high level functions. Menus were not
- included to avoid confusion when evaluating the code as to the processing
- calls verses the menuing code. All exe's are demos for LEADTOOLS DOS 16bit
- and are limited to an image with of 15,000 pixel. All 32Bit demo hove no
- size limit and run 6 to 8 times the speed performancs of this demo.
-
- When compressing with JPEG (JFIF, or JTIF) notice that support has been given
- for 4:4:4 (1:1:1) use JPEG or JTIF, 4:2:2 use LEAD2JFIF or LEAD2JTIF, and
- 4:1:1 use LEAD1JFIF or LEAD1JTIF color sub-samplings.
