New modules in development?

[Michael Clease]

IF i get some time i might look into writing a gfx file format module

jpg to RGB
png to RGBA
...

no point listing all of them.

Just thinking PB or C++, i will only say it make take some time.

Abraxas,

that would be a great addition!

Thanks a lot

Only good messages from tB world

That would be great Abraxas,
good luck with your project !

What does anyone know about http://freeimage.sourceforge.net/

would that be worth looking at?

[ErosOlmi]

Yes, of course.

And Mr. Josè Roca (as usual) has already developed Power Basic wrappers: http://www.jose.it-berater.org/smffo...php?topic=82.0
I think FreeImage.inc file produced by Josè can be used in thinBasic quite out of the box. Maybe few changes are needed like define RGB QUAD type and remove the WIN32API.INC include file that is Power Basic related.

[code=thinbasic] Type RGBQUAD
rgbBlue As Byte
rgbGreen As Byte
rgbRed As Byte
rgbReserved As Byte
End Type[/code]

Maybe someone with some (well, a lot of) free time can have a look and produce some script example.
The biggest problem I see is that FreeImage lib uses callbacks and callbacks are not possible in thinBasic due to its interpreted nature and structure. So a wrapper module is needed.

Abraxas, yeah Kent would like to see such a module for sure. So go for it!

Here is the current commandset for the Path module:

TPath_NodeExist   
TPath_AddNode    
TPath_DeleteNode  
TPath_GetChildCount
TPath_GetChildNode 
TPath_AddChildNode 
TPath_DeleteChildNode
TPath_GetChildCost 
TPath_SetChildCost 
TPath_GetNodeCount 
TPath_SetNodeActive 
TPath_SetNodeX   
TPath_SetNodeY   
TPath_SetNodeZ   
TPath_GetNodeActive 
TPath_GetNodeX   
TPath_GetNodeY   
TPath_GetNodeZ   
TPath_GetDist2D   
TPath_GetDist3D 
TPath_SaveNodes  
TPath_LoadNodes   
TPath_Init

Now of to the path calucation function, some path retrieving stuff and then documenting everything. That I like the most, NOT! And of course, writing some
sample scripts.

Thanks Mike, I have never worked with pathing commands before, but it looks like a nice list of commands, thanks for the preview list!

Yes, an image handling module would be fantastic Abraxas!

Hi,

path module sounds really cool !
Such a wide command set is promising indeed !

Abraxas, your module idea looks good, only possible trouble is that just FreeImage is over 1 MB DLL, so this could expand size of applications a lot. This is why my implementation of JPG and PNG loader is not here, as I wanted to code it on my own to keep size down. Sadly, currently I have no time resources to do it.


Thanks,

I will dig out my file format book and start reading up when i get time which doesnt look too good at the moment.

i was thinking of bmp,jpg,tga,tiff,png.gif.

Petr,

why not using GDI+?
OK, it is not defaulted present in OS before Win2K but it will not require any new lib.
If you use dynamic linking (and not static) you will be able to determine if GDI+ is present or not. And consider GDI+ can be downloaded from Microsoft to be used also on Win9X OSs.
Also you only need to make few function just to load JPG (for example) images and convert on the fly to BMP buffers in memory.

The GdipCreateBitmapFromFile seems what you need. Example:
[code=vb]
'...
LOCAL hStatus AS LONG
LOCAL pBitmap AS DWORD

strFileName = UCODE$("Any.jpg") ' <-- change
hStatus = GdipCreateBitmapFromFile(strFileName, pBitmap)
'...
[/code]
What do you think?

PS: as usual, Josè forum is the source of those info: http://www.jose.it-berater.org/smffo...hp?topic=259.0
