[RESOLVED] Vampyre Imaging Library problems

[NelsonN]

Just when I solve one problem another one pops-up.

I am using the Vampyre Imaging Library in an older program I am trying to get to compile with the latest Lazarus.

Here's the problem at runtime now.

When I add the Vampyre Imaging Library 0.26.4 to the project I don't get icons on components like buttons yet they operate just fine.

When I add the vampyreimaging from the Online Package Manager I see all the icons on the components, but the library function LoadImageFromStream doesn't do its function.

Code: Pascal  [Select][+][-]

1. function TForm2.SizeThumbs(Var ImageThumbsArray: TBitbtn; Img_Copyrect: Integer;
2.   ThumbH: Integer; ThumbW: Integer; Var ImgMS: TMemoryStream) : Integer;
3. var
4.   Img, Img2 : TImageData;
5.   ImgH, ImgW : Integer;
6.   i{, returnWidth} : Integer;
7. begin
8.   try
9.     InitImage(Img);
10.  
11.     NewImage(ThumbW, ThumbH, ifR8G8B8, Img2);
12.  
13.     ImgW := 0;
14.  
15.     ImgMS.Position := 0;
16.  
17.     LoadImageFromStream(ImgMS, Img);  // DOES NOT WORK with vampyreimaging from the Online Package Manager
18.     ImgMS.Position := 0;
19.     ImgMs.Size := 0;

What is ImgMS ??

Must contain a magic bytes

Example
if ImgMS a bmp 
ImgMS.ReadByte 1 // 42
ImgMS.ReadByte 2 // 4D
