Quite a regular

Hi All,

Following the last message concerning DataTypes, I manage to have my images loaded and everything work perfectly, images are ok on screen and on 3D objects but.... Because there is always "but" somewhere ... I get random DSI error ...
When I choose "ignore DSI errors", the program run perfectly and all images are displayed on screen like they should. Showing they are loaded ...
So, what's wrong ? I didn't find why ...

Here is the code :


#include <stdlib.h>

#include <stdio.h>



// #include <amiga-align.h>

#include <datatypes/datatypes.h>

#include <datatypes/pictureclass.h>

#include <clib/alib_protos.h>

#include <proto/datatypes.h>

#include <proto/exec.h>

#include <proto/dos.h>

#include <proto/intuition.h>

#include <proto/graphics.h>

// #include <cybergraphx/cybergraphics.h>

// #include <proto/cybergraphics.h>

// #include <default-align.h>



#include <exec/memory.h>



// struct IntuitionBase *MyIntuitionBase;

// struct GfxBase *GfxBase;

// struct Library *CyberGfxBase;

struct Library *DataTypesBase;

struct DataTypesIFace * IDataTypes = 0;

/*

struct MyPicture{

  int Width;

  int Height;

  int Depth;

  unsigned char *Pixels;

 };

*/

struct MyPicture * AllocPicture( int Width, int Height, int Depth ){

  struct MyPicture *pt = NULL;

  int Bytes;

  Bytes = Depth / 8;

  pt = (struct MyPicture *)IExec->AllocVec( sizeof( struct MyPicture ), MEMF_ANY|MEMF_CLEAR );

  if ( pt ){

    pt->Pixels = IExec->AllocVec( Width * Height * Bytes, MEMF_ANY );

    pt->Width = Width;

    pt->Height = Height;

    pt->Depth = Depth;



    if ( pt->Pixels == NULL ){

      IExec->FreeVec( pt );

      pt = NULL;

     }

   }

  return pt;

 }



void FreePicture( struct MyPicture *pt ){

  if ( pt ){

    IExec->FreeVec( pt->Pixels );

    pt->Pixels = NULL;

    IExec->FreeVec( pt );

   }

 }



struct MyPicture * LoadPicture( APTR FileName, int Alpha ){

  struct MyPicture *pt = NULL;

  Object *dto = NULL;

  ULONG nb;

  struct BitMapHeader *bmh = NULL;

  struct pdtBlitPixelArray bpa;

  void * bpaptr = &bpa;



  if ( !FileName ) return NULL;



  DataTypesBase = IExec->OpenLibrary( "datatypes.library", 43 );

  if ( DataTypesBase ){

    IDataTypes = ( struct DataTypesIFace *)IExec->GetInterface( DataTypesBase, "main", 1, NULL );

    if ( IDataTypes != 0 ){

     dto = ( Object *)IDataTypes->NewDTObject( (STRPTR)FileName,  DTA_GroupID,        GID_PICTURE,

                                               PDTA_DestMode,     PMODE_V43,          PDTA_Remap,

                                               FALSE,             TAG_DONE );

      if ( dto ){

        nb = IDataTypes->GetDTAttrs( dto, PDTA_BitMapHeader, &bmh, TAG_DONE );

//        nb = IIntuition->GetAttr( PDTA_BitMapHeader, dto, &bmh );

        if( nb != 0 ){

          int resread;

          printf( "Sizes: %dx%dx%d\n", bmh->bmh_Width, bmh->bmh_Height, bmh->bmh_Depth );

          /* Allocation de la structure Picture et du buffer m?moire */

          pt = AllocPicture( bmh->bmh_Width, bmh->bmh_Height, 32 );

          if ( pt != NULL ){

            bpa.MethodID = PDTM_READPIXELARRAY;

            bpa.pbpa_PixelData = pt->Pixels;

            bpa.pbpa_PixelFormat = Alpha?PBPAFMT_RGBA:PBPAFMT_RGB;

            bpa.pbpa_PixelArrayMod = bmh->bmh_Width * 4;

            bpa.pbpa_Left = 0;

            bpa.pbpa_Top = 0;

            bpa.pbpa_Width = bmh->bmh_Width;

            bpa.pbpa_Height = bmh->bmh_Height;

            resread = IIntuition->IDoMethodA( dto, bpaptr );

//            resread = IDataTypes->DoDTMethodA( dto, 0, 0, bpaptr );

           }else{

            printf( "Cannot allocate memory for mypicture structure\n" );

           }

         }else{

          printf( "Impossible to read image data informations\n" );

         }

        IDataTypes->DisposeDTObject( dto );

       }else{

        printf( "Unable to load file\n" );

       }

      IExec->DropInterface( ( struct Interface * )IDataTypes );

     }else{

      printf( "DataType interface cannot be opened" );

     }

    IExec->CloseLibrary( DataTypesBase );

   }else{

    printf( "impossible to open datatypes.library ver 43+\n" );

   }

  return pt;

 }

As you can see in the source code, I tried both Intuition and Datatypes funcions to get Objects attributes and to do method ... Same result ...

EDIT :
Apparently the crash came from MiniGL.library and not from DataTypes as I can see in the crash log file :
"Crash occured in module minigl.library at address 0x6F5C2384"
Symbol Info :
Instruction pointer 0x6F5C23B4 belongs to module "minigl.library" (HUNK/Kickstart)

Hope someone already experienced this and can help :)

EDIT :
After some tests, I suspect WarpPNG is faulty because if I change the WarpDT prefs, I get other issues with images and DSI errors ...

Regards,
AmiDARK.

All we have to decide is what to do with the time that is given to us.
