Re: drawing string on bitmap and painting onto 2d widget

Re: drawing string on bitmap and painting onto 2d widget

You can update it
it will only replace files from the OS3D setup not yours.
(save only modified plugITs if you have some)

Re: drawing string on bitmap and painting onto 2d widget

I did some tests (in 3D and in 2d graphic with a CompBitmap), i get the same result than hebdemnobad.
Maybe a hardware support not supported by the CG or the driver ?

hebdemnobad, try to change the background color of the 3d scene and/or the ambient light. Same result ?
In my tests, the rendering changes ...

Re: drawing string on bitmap and painting onto 2d widget

the original problem was also on compbitmaps.

and I've debugged with a simple draw on compbitmap with a background container.
I didn't saw the problem at all since I've corrected the bitmap8 palette hmm

iri can you send me yours tests so I could try to reproduce it with this ones

Re: drawing string on bitmap and painting onto 2d widget

In fact, the "system (!)" background seems to set in a transparency mode (hardware support, driver, ...).

For code, i deleted them, i had just written them quickly. hmm
If our friend can try too, we'll see better and reproduces easier this problem.

Re: drawing string on bitmap and painting onto 2d widget

Here the code I used for the test.
Does it make the same problem you mention ?

  if txtList == nil then [w+1 h]
  else let txtList -> [first next] in
       let _GETstringSize font first -> [nw nh] in

fun getStringSize(font, str)= getStringSize2 font (lineextr str) 0 0;;

  let wsize -> [texWidth texHeight] in
  let tsize -> [tw th] in

	  //bitmaps copied in alpha bitmap so we can destroy them
	  _DSbitmap bmpRgb;
	  _DSbitmap8 bmp8;
	  
	  abmp;
	);
  );;
 
 
fun main()=	
  _showconsole;
  let _CRfont _channel 12 0 0 "Lucida Console" -> font in
  let [10 10] -> [xmargin ymargin] in
  let "Arkeon and Iri help me all the time!" -> text in

Re: drawing string on bitmap and painting onto 2d widget

hmm hmm

did the transparency change or is it always the same on restarts ?

This can be because of the texture resolution and graphic conversion loosing precision.

try this :
- create a larger and squared texture like 512x512
- set the font larger with the bold flag

sometimes the text appears white, but most of the time it is grey. i will follow your suggestions. here is my code, I think it tracks yours more or less:

    );
    
    //bitmaps copied in alpha bitmap so we can destroy them
    _DSbitmap bmpRgb;

Re: drawing string on bitmap and painting onto 2d widget

lol ^^ this is my fault, in the example I set the text color to 0xff
so it build a 0xff0000 color only red, in grey this correspond to 85 not 255

just replace 0xff to 0xffffff

an academic/technical question....but if you are painting into a 8bit bitmap, why do you need a full color of 0xffffff?

Re: drawing string on bitmap and painting onto 2d widget

hello collleagues:

something in 1.6.4 broke the multiplayer script. the os3d editor checks the code fine on start up, but if I run the scene, the voyager crashes.  Arkeon I am emailing you the log. Iri let me know if you want to see it.

fwiw here are the last few lines of the log:
