[nRGBlib] W.I.P - Colorful librairy for Ndless 3.1

[totorigolo]

Hello everybody,

I'm coming from TI-Planet to inform you about the progression of nRGBlib, which is a Ndless colorful (but compatible with classic Nspire) library.
You can see the corresponding news :

• v0.1 : http://www.omnimaga.org/index.php?topic=11992.0 (EN) (thanks to jimbauwens)
• v0.1 : http://tiplanet.org/forum/viewtopic.php?t=8591 (FR)
• v0.2 : http://tiplanet.org/forum/viewtopic.php?t=8672 (FR)
• v0.3 : http://tiplanet.org/forum/viewtopic.php?p=123024 (FR)

And you can see the original topic on TI-Planet here (FR). Note that this topic, on Omnimaga, may be outdated because I'm French so...
------------------------------------------------------------------------------------------

Roadmap :

nRGBlib 0.1 : First stable version - available on request

• Drawing pixel in color.
• Clearing the screen in color.
• Drawing an ordinary line in color.
• Drawing rectangle, square or vertical and horizontal line in color.
• Drawing circle and disc in color.
• Drawing an empty triangle (only borders) in color.
• Drawing 8x8 pixels tile (good definition, but in french) with possibility to resize them (only x2, x4,... for 0.1 version) in single color and multi colors mode.
  
• Drawing a character with possibility to resize it (only x2, x4,... for 0.1 version) in color.
• Drawing a string, with possibility to resize it (only x2, x4,... for 0.1 version) and possibility to enable / disable line wrap, in color.

nRGBlib 0.2 : Former stable version - public

• Compile statically, like libndls, to alleviate the executable.
  
• Organize the library to allow proper expansion in continuity.
  
• Classic Nspire and CX compatibility, without re-building.
  
• Reduce the number of arguments of the functions, to accelerate the execution → only colors for this version.
  
• Mozilla Public License 2.0 added.
  
• Version ready for Ndless 3  
  

nRGBlib 0.3 : Last stable version - public

• Images support. The images' format is a custom one. However, an exporter is provided and is capable to export all popular formats (bmp, dds, jpg, png, tga, psd (thanks to SFML   ) ).
  The images' weight is smaller than BMP, but heavier than PNG : 320x240 image => BMP = 225Ko, PNG = 6.19Ko et CUSTOM = 151Ko.
  Images are saved outside of the program, unlike tiles.
  Currently, 4bpp calculators can't draw images which have uneven width, so 240x245 is bad → 240x244.
  
• Sub-images support, ie drawing only a part of an image.
• Buffering support. Possibility to use several screen buffers and to make a screen shot (but can't save it yet).
• Boost of the drawBox() function, which is used by several others. The former version, slower, is still available : drawBoxSl().

------------------------------------------------------------------------------------------

Features:

nRGBlib is composed of several packages to perfectly suit your needs.

• nCOMMON:
  
  • Color, RGB <-> BW conversion, precomputed colors.
  • Screen buffer, creation, drawing, screen shootinh, clearing.
  • setPixel(), clearScreen().
• nGEO:
  
  • Shapes: Discus, Circle, Line, Rectangle, Square, Triangle.
  • Display functions of these shapes.
• nTILE:
  
  • Tile 8x8 in one color or in multicolors.
  • Display functions of tiles.
  • → Tiles are saved INSIDE of the program.
• nIMAGE:
  
  • Image, initializing, loading, drawing, getPixel().
  • Sub-image, initializing, loading, drawing, getPixel().
  • → Images are saved OUTSIDE of the program.
• nGUI:
  
  • Structures: Letter, Text.
  • Display functions of these structures.
• nMATHS:
  
  • rand() and randMinMax() functions.

4bpp drawing has been accelered a lot since v0.3, but the video was taken before the optimization.

Very nice totorigolo
I've been looking into my copy, and it looks very straitforward to use. I haven't done anything with it yet, but I definitly will

[totorigolo]

The 0.1 version is in only one file, and I didn't pay attention about organization. In the future version, the code will be more structured 

[adriweb]

This lib is awesome

You should post a screenshot/video

[epic7]

This looks useful!
I can't wait for ndless 3 to come out

 

[totorigolo]

Adriweb: Done ! I used the same images than jimbauwens.

epic7: Thanks you !

[Nick]

when watching that video, it looks like you're gonna be burried below a bunch of colored circles, since they seem to come closer xp

but it's really great, this will be a big help in game development.. congratz

[DJ Omnimaga]

Looks very nice, any demo will be available soon?

Keep us updated when you can

[totorigolo]

What do you mean when you say "demo" ? Ndless 3 isn't yet public. Currently, there are CXSnake and GeometriCX. (Perhaps CXSnake screen shots ?  )

[DJ Omnimaga]

Oh I meant so we can test it, but yeah you're right about Ndless . Maybe more animated screenshots?

[totorigolo]

New video on the presentation topic, about compatibility between Nspire CX / Nspire Touchpad/Clickpad.

<a href="http://www.youtube.com/watch?v=R5gHYONwilg" target="_blank">http://www.youtube.com/watch?v=R5gHYONwilg</a>

I did this compatibility with the following formula : color = ((R + G + B) / 3) / 16; and then I use the Ndless 2.1 setPixel(); function.
I have also edited my Color structure to be able to do this :

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9

//...     Color appleCol; // Red for CX and Black for Classic         appleCol.R = 255; // |         appleCol.G = 0;   // |-> Red         appleCol.B = 0;   // |         appleCol.BW = 0; // Black     drawSthColor(x, y, appleCol);     //...

Nice video and great work!

[totorigolo]

Here it is ! The new nRGBlib v0.2 . It will be available soon to Download... 

[Jim Bauwens]

Very nice !
I'll soon take a look at it

[DJ Omnimaga]

Pretty good so far
