Native Imagelist

[Harry Rogers]

Hi

 

I can't figure out how to use a UniNativeImageList  as the picture source for a UniImage.

I've tried all the obvious ( to me at least ) assignments without luck  even resorting to this horror ! >>  

 

uniimage2.LoadFromStream(Tstream(uninativeimagelist1.Images[0].MemoryImage));

 

I'm sure it must be simple to do.

 

Anyone care to enlighten me ?

 

Many thanks

Hi

UniNativeImageList1.GetBitmap(0, UniImage1.Picture.Bitmap);

This will be available in build 1295 which I will publish soon.

 

Thanks

Hi,

 

You can try as follow

UniNativeImageList.GetBitmap(0, UniImage2.Picture.Bitmap);

Thanks Farshad

 

I tried

 

 uninativeimagelist1.GetPng(0,tpngimage(uniimage0.Picture));

 

this gives the error 'Privileged instruction'.

 

All the best

Normally you can't typecast Picture to PngImage  unless it already holds a PNG image internally.

You can try loading image into a temporary image then assign it to uniImage.

[Farshad Mohajeri]

var
  P : TPngImage;
begin
  P := TPngImage.Create;
  try
    UniNativeImageList1.GetPng(0, P);
    UniImage1.Picture.Graphic.Assign(P);
  finally
    P.Free;
  end;

Note: Requires build1295

I've tried just about every combination I can think of up and down the object hierarchy but can't find a solution.

I think I will pre-load the PNGs into a directory and simply use a loadfromfile in each case.

 

would it be possible to add a property/method to the UniNativeImageList that returned a Tpicture or have a UnImage descendant that had imagelist & image index properties ?

 

Many thanks

Build 1295 is being uploaded.

 

Please try my suggested solution with it.

[Harry Rogers]

Thats working fine now, as per your example with 1295.

 

Reported - fixed - built - Uploaded - Downloaded - built -  tested  < Two and Half Hours>.

 

That's a pretty amazing service.

 

Thank you

I wish we could bring resolutions to all issues as fast as this. Some issues may wait for months before we can find some workaround or solution.
