Hi,

I'd like to know if it's possible to add image plugins as UserLibraries, so they can be used with LoadImage() and SaveImage(), and how to do it. Thanks,

I will post an example tonight and put it in the SDK if I got some time.

Hi,

I've played a bit with the example and finally built a PureBasic library (doesn't decode for now, just returns width and height).

But PB complains: can't create PureBasic.exe

NAsm.out says:

Code: Select all

Functions\Image .text: undefined reference to 'PB_ImageDecoder_Register'

This is my desc file:

Code: Select all

ASM
;
0
;
LIB
;
1
ImagePlugin
;
ImagePlugin
; Version 1.0
UsePPMImageDecoder
None
;
;UsePPMImageEncoder
;None
;

This is the related part of the asm file:

Code: Select all

; Header:
extrn PB_ImageDecoder_Register

public PB_UsePPMImageDecoder

; Procedures GetWidth, Check, etc.

PB_UsePPMImageDecoder:
    cmp [Registered], dword 0
    jne .end
    mov [ID.Check], Check
    mov [ID.GetWidth], GetWidth
    mov [ID.GetHeight], GetHeight
    mov [ID.Decode], Decode
    push dword ID
    call PB_ImageDecoder_Register
    mov [Registered], dword 1
  .end:
    mov eax, [Registered]
    ret

Anyone can give me a clue about this? I'm thinking of going back to Nasm, I'm not familiar with Fasm and most the problems I've had with the code was related to the different syntax.

Weel, that's all for now, thanks,

El_Choni

SDK? Where could one download such an item?

The SDK for making userlibs is in your purebasic dir

El_Choni:

It's _PB_ImageDecoder_Register@4 (C stdcall convention). Should work then.

Just out of curiosity, why did we change from Nasm to Fasm? (Spasm is next, I think

) Is Nasm not multiplatform?

Thanks, Fred! It works now, and I'll be able to code some plugins
