Drawing pixel resolution graphics in text mode

or use colorshow.exe with is faster but has the disadvantage that is ISA(Istruction Set Architecture) dependent.

Not sure what you mean depends on x86 instruction set ??

Yes depends on x86.

einstein1969

Excuse me. I am afraid I don't understand what you intended to mean with "colorshow.exe... has the disadvantage that is ISA (Istruction Set Architecture) dependent... (depends on x86)".

Of course, colorshow.exe program requires an x86 compatible CPU (and Windows OS) in order to run, but the same "restriction" apply to thousand or perhaps millions of applications of all kinds, from small freeware programs up to several hundred dollars suites, that are distributed exclusively as .exe executable files for x86 Windows OS. Is your opinion that all these applications "have the disadvantage that depends on x86"? Or, do you have this opinion just on my colorshow.exe program?

Is your post an advice that if someone use colorshow.exe program to show text in color, he/she must be aware that this solution will not longer works if he/she later change the computer for a non-x86 compatible one?

As I said before, I don't understand what you meant...

Antonio,

I only notice the dependencies. 1) closed source 2) developed by one person 3) written in a low-level language for a particular ISA.
What does this mean? That all the work that you did not survive very long.
Of course, even if Microsoft were to remove all of the functionality we would have had problems. But in this case depends on someone else.

with respect

1) I am sure if you asked nicely he would provide the source.
2) Why is a one person developer such a bad thing?
3) It's pretty much going to run on any computer running Windows which is what the utility is intended for. Are you expecting it to run on Android tablets running on ARM processors?

I have tried this code, but at resolution 512x384 and above the result is broken



for resolution 320x200 i have no prolem.


I have tried a very simple dithering and the font 1x1 look very good!

Yes, the problem is caused by a small bug in ColorChar.exe program. The original output buffer size was 1024 characters, but when the number of adjacent pixels of same color was larger, the bug appear. I changed that size by 8192, but obviously I used the previous version when I posted the code here...

Just change the ColorChar.exe resource section by this one:

Then delete ColorChar.exe file from disk and run the program again.

I also fixed the code in the original post.

PS - That color dithering is amazing!

[Aacini]

If you want to display text in the 1x1 pixel resolution "graphics" screen, a method to map a font definition table into pixels in the screen is needed. I developed a preliminary Batch-JScript hybrid version of such method as a prototype before write the assembler .exe final version. The result is very good:





The prototype version use a simple one-byte wide table for the font definition, so all characters are 8-pixels wide although they may have any height size. Joseph Gil's fntcol16.zip package is a collection with 280 files of such simple font definition tables, although many of them have the same characters in 32-127 range and just a few different characters in the high range; previous image was created using VGA-ROM.F08, VGA-ROM.F14 and VGA-ROM.F16 files from such collection. The final version of the show text routine will use .FNT format files instead that have not restrictions in the font size. Currently exist programs to convert .FON and .TTF files into .FNT ones. DaFont.com is a site with more than 23,000 fonts divided in a large range of themes where you can download .FON and .TTF font files.

The image below show a few of the fonts included in fntcol16.zip collection.





The code of the program that create previous images is included below. Of course, you must previously download and extract the *.F## files from fntcol16.zip collection in order for this program to work.

IMPORTANT: Previous program must run in a MS-DOS command-line window with the Terminal 1x1 font installed and requires ColorChar.exe auxiliary program, as described in the first post of this thread; these requirements will be fulfilled when you successfully draw the Mandelbrot Set at any resolution. This example program was adjusted for 512x384 screen resolution, but it will also show correct results in larger resolutions although with apparently smaller characters.

Hi Antonio,

The work done with the font is gigantic and fantastic!

I'm surprised your ability to synthesize and speed of execution.

I, unfortunately I have not yet mastered what have you and go slow with color management.

Now I'm working on the luminance and the distribution of pixels, an old job I had started to do that but I stopped because I did not know how to overcome the problem of large env. I had opened a thread but remained unanswered.

These are just studies and I still have nothing ready and fully automated.

This is achieved by using only findstr.exe, reads images directly without external tools. Unfortunately, even though I created a queue to optimize call findstr is still a little slow.

In addition, not having the possibility of a multicore can not use this option together with "mode" trick.

Work proceeds on the quantization

using only 14 colors and no dithering, using your font 1x1 (this is not colored version!)

On the right the original image, on left pure batch image viever:

[einstein1969]

Hi to all,

I do not know if anyone will go in using the text mode to draw in colors. I just wanted to show what you get with a batch basis.

I believe that it is necessary to make some animation, however, the assembler or something that does not exist yet.

Previus result with Lucida 5: (we can use over 300 simultaneous uniform colors!)




However, I used the font Lucida Console size 2 (I think I found a bug that allows you to do that, at least on my windows 7 32bit). The font size is 1x2.

The colors are unfortunately not uniform. But it has a very interesting hardware dithering. Look the sphere in the next picture. The code is the same of above picture. We should not implement dithering and run it in batch software.

New results with raster 1x1 e Lucida 2:



In this above image I have tested also with lines and antialiasing in Lucida Console 2.

Click on image and look at full size or expand with zoom graphics software.

Aacini I found a way of load automatically the font without install it permanently. No manual installation is needed, and works with non admin accounts.

See this: Pixelfnt v1.21 set a font of 1x1

Yes, carlos, I saw that post. I think that that method is very good (currently I have some old fonts installed in my computer that remains from my first tests ).

Why did you deleted the link to your source code? Perhaps you may send me the link via PM.

Gracias Carlos!
