[SOLVED]Dynamic array as pointer

[creaothceann]

So that is different than using ResourceString ?

ResourceString is for translations. Embed etc. is for binary data.

ResourceString is for translations. Embed etc. is for binary data.

For those that are curious: all  resourcestring  does is place the identifiers and addresses of associated strings in a special global table so they can be accessed by translation routines; it doesn't do any resource management on its own.

Here is the code

Code: Pascal  [Select][+][-]

1. procedure DrawPicture(x, y : Integer; img : Pointer);
2. var x1, y1 : Integer;
3.     temp   : array of array of Integer;
4. begin
5. temp := @img;
6.  
7. for x1:=Low(temp) to High(temp) do
8.     begin
9.     for y1:=Low(temp) to High(temp[0]) do
10.         begin
11.         ScaledPixel(x1 * SCALE + x, y1 * SCALE + y, temp[x1, y1], SCALE);
12.         end;
13.     end;
14. Pointer(temp) := Nil;
15. end;
16.  

The main issue here is that an array of array of X is on the first level an array of Pointer. So you can't simply convert a flat two dimensional array of values to such an array, because then the variable would interpret the values inside the first array as pointers to the sub arrays.
