FBImage static Win/Lin 32/64-bit

Post by D.J.Peters »

I created a tiny FBImage lib it's a small subset of library SOIL.

download: FBImage.zip (Windows/Linux 32/64-bit) Thu Nov 02, 2017
(source code as Code::Block project are included)

You can save PNG and load BMP, TGA, DDS, JPG and PNG images as FBImage from file or memory but not interlaced "Progressive" JPEG.

(if you need the dimension of any loaded image use ImageInfo img,w,h)

test_alpha.bas

Code: Select all

#include once "FBImage.bi"

' load RGBA png (with alpha channel)

chdir exepath()

screenres 640,480,32 ' RGBA

line (0,0)-step(639,479),&HFF0000FF,BF

var img = LoadRGBAFile("lights_alpha.png")

put (0,0),img,ALPHA

sleep
ImageDestroy img

Of course the result of LoadRGBAFile() and LoadRGBAMemory()
is an 32 bit fbgfx image so you can use it with 24 or 32bit fbgfx modes.
If you need RGB images in 16 bit mode here a simple converter.

Joshy

Code: Select all

#include once "FBImage.bi"

' load (32bit) RGBA jpg image and convert it for 16 bit RGB mode
#define RGB16(_r,_g,_b) (((_r shr 3) shl 11) or ((_g shr 2) shl 5) or (_b shr 3))
function Load16BitRGB(filename as const zstring ptr) as any ptr
  var imgSrc = LoadRGBAFile(filename)
  if imgSrc=0 then return imgSrc
  dim as integer w,h,spitch,dpitch
  dim as ubyte ptr s
  imageinfo imgSrc,w,h,,spitch,s
  var imgDst = ImageCreate(w,h,0,16)
  dim as ushort ptr d
  imageinfo imgDst,,,,dpitch,d 
  dpitch shr= 1 ' pitch in bytes to pitch in pixels

  for y as integer =1 to h
    dim as integer i
    for x as integer =1 to w
      d[x] = RGB16(s[i],s[i+1],s[i+2]) 
      i+=4 ' next source pixel
    next
    s+=spitch ' next src row
    d+=dpitch ' next dst row
  next
  ImageDestroy imgSrc
  return imgDst

end function

chdir exepath()

screenres 640,480,16 ' <-- 16bit 

var img = Load16BitRGB("tire.jpg")

put (0,0),img,pset

sleep
ImageDestroy img

hi !
can you add an option for creating windows hbmp object or a bitmap array in memory instead of fb image ?

Hello Chung,
Windows bitmaps are DWORD aligned per scanline
FreeBASIC bitmaps are 16 byte aligned per scan line.

You can create it self from pixel pointer (ImageInfo)

1.) Load it temporary as RGBA FreeBASIC image
2.) Create a buffer in the right format for CreateDIBSection, SetDIBBits or copy/convert pixels for CreateCompatibleBitmap ...
3.) Delete the temporary loaded FreeBASIC image ImageDestroy()

I don't add OS specific code to the FBImage library.

By the way all stuff from you is windows only. :-(
I saw you used my fltk-c wrapper only for loading images from memory.
Why not replacing your "Chung GUI" windows only stuff with FLTK widgets including the OpenGL widget ?

for cross platform program i use webgl which works on mac too...
i use gui_chung because it reminds me liberty basic (i started programming on pc with it) people uses liberty basic because it is simple and easy though it is 1000 times slower than freebasic

Not sure if it is me or FBImage.
ImageDestroy fails upon destruction of type.

This is "stripped down"

Ok, been banging my head on this for a week and still do not understand.

LoadRGBAFile() returns 'Any Ptr'
ImageInfo() WORKS
ImageDestroy() accepts 'Any Ptr' BUT FAILS

Code: Select all

#Include Once "FBImage.bi"

Dim As Integer W, H
Dim As Any Ptr AllCardsGr = LoadRGBAFile("card-deck-01.jpg") 'use FBImage
If AllCardsGr > 0 Then
	ImageInfo(AllCardsGr, W, H)
	Print "Graphic details: ";W;" by";H
	Sleep
EndIf
'....
Print "Destroying...."
If AllCardsGr > 0 Then ImageDestroy(AllCardsGr)
Print "Done"
Sleep

hello bcohio2001
if you use Linux which distro and 32 or 64 - bit ?

(no problem with Windows 32 - bit here)

@Joshi,

[edit]Sorry, my fault: extended it with error-check an forgot to dereference zstring ptr[/edit]
there seems to be a problem on WIN64 too --> [solved]:
tested with FBC for WIN64 ver. 1.04.0 / 1.05.0 --> hangs on program exit (test_alpha.bas) see above! --> now: OK !!!
tested with FBC for WIN32 ver. 1.05.0 --> OK [funny, should have kicked the same error!!!]
compiles done with full error checking, e.g.:
fbc -s gui -exx -w pedantic "test_alpha.bas"
(after sorting out the missing ByVal stuff in .bi file)

OS: WIN 8.1 pro / US-EN / 64bit

dkl pointed me in the right direction http://www.freebasic.net/forum/viewtopi ... 46#p215746

Not only every scanline are 16 byte aligned the image pointer self too.

That is clever and makes sence :-)

As a workaround you can use free() instead of ImageDestroy() from the C runtime lib. #include "crt/stdlib.bi"

I must fix it next week

Using Win10 64 bit. But still using v1.4 32 bit Freebasic. Never had a problem with this combination, until now.
Your examples ran fine with the 'Var' declaration. But I needed 'Any Ptr' for inside the 'Type'.

So maybe it was 'me'? Will get latest of FBImage and get Freebasic v1.5 64 bit and see ....

FYI ImageDestroy() with 'Any Ptr' param now works with the new FBImage.

OK, Mr. Peters, as per your suggestion....
I download FBimage and unzipped into my FreeBasic folder as seen here:
Image
Now, my question is where do I put all those different files?

I use FBide as my editor

I have my FB programs in various folders and sub-folders in different places on my hard drive

So, where do I put these FBimage files, and then do I just put an '#include' in the program I want to use it with, no matter where I have that program saved? Do I have to tell FBide where to find FBimage so it can link?

sorry these are all so newbie questions.... I really miss not being able to deal with PNGs directly.....
