Bitmaps
|
|
=======
|
|
|
|
Bitmaps in Simba are internally all instances of *TMufasBitmap*. Scripts should
|
|
generally access bitmaps using their *handle*: an integer. All functions
|
|
referenced here either require a bitmap *handle* or return one.
|
|
|
|
If you want to gain more access over a specific bitmap, see the
|
|
*GetMufasaBitmap* function. It is highly unrecommended to create bitmaps with:
|
|
|
|
.. code-block:: pascal
|
|
|
|
var bmp: TMufasaBitmap;
|
|
bmp := TMufasBitmap.Create;
|
|
|
|
Because there is no way to get a *handle* to this bitmap; as it will not be
|
|
managed by Simba internally. (All Bitmaps created by *CreateBitmap* are managed
|
|
by Simba, if you don't know what this means: you generally want Simba to manage
|
|
the bitmaps)
|
|
|
|
If you still want access to the TMufasaBitmap, use *GetMufasaBitmap*, described
|
|
below.
|
|
|
|
GetMufasaBitmap
|
|
---------------
|
|
|
|
.. code-block:: pascal
|
|
|
|
function GetMufasaBitmap(bmp : integer) : TMufasaBitmap;
|
|
|
|
Returns the *TMufasaBitmap* for the given bitmap. They both reference the same
|
|
bitmap. TMufasaBitmap is a more advanced interface to bitmaps in Simba.
|
|
There is no way to get a *internal* (integer)
|
|
reference to a bitmap if you create it with TMufasaBitmap.Create; so the
|
|
recommended way is to use *CreateBitmap* to get the integer reference/handle and
|
|
then call this function to get the class reference.
|
|
|
|
|
|
.. code-block:: pascal
|
|
|
|
var bmp: TMufasaBitmap;
|
|
bmph: integer;
|
|
bmph := CreateBitmap(100, 100);
|
|
bmp := GetMufasaBitmap(bmph);
|
|
|
|
bmp.SetSize(150,150); // also changes bmph, as they are the same bitmap.
|
|
|
|
|
|
CreateBitmapString
|
|
------------------
|
|
|
|
.. code-block:: pascal
|
|
|
|
function CreateBitmapString(bmp : integer) : string;
|
|
|
|
Creates a string for the given bitmap.
|
|
|
|
CreateBitmap
|
|
------------
|
|
|
|
.. code-block:: pascal
|
|
|
|
function CreateBitmap(w,h :integer) : integer;
|
|
|
|
Create a bitmap with width *h* and height *h*. Returns the bitmap reference.
|
|
|
|
|
|
FreeBitmap
|
|
----------
|
|
|
|
.. code-block:: pascal
|
|
|
|
procedure FreeBitmap(Bmp : integer);
|
|
|
|
Free the bitmap. You should do this when you no longer need the bitmap.
|
|
Be careful when working with bitmaps: not freeing it when you no longer need it
|
|
leads to memory leaks, which will eventually make your script crash. (Unless you
|
|
stop it in time, in which case Simba will free the bitmaps for you)
|
|
|
|
SaveBitmap
|
|
----------
|
|
|
|
.. code-block:: pascal
|
|
|
|
procedure SaveBitmap(Bmp : integer; path : string);
|
|
|
|
Save the given bitmap to the specified path.
|
|
|
|
BitmapFromString

|
----------------
|
|
|
|
.. code-block:: pascal
|
|
|
|
function BitmapFromString(Width,Height : integer; Data : string): integer;
|
|
|
|
Load a bitmap from the given string. This command is usually generated with the
|
|
Bitmap to String feature in Simba.
|
|
|
|
|
|
LoadBitmap
|
|
----------
|
|
|
|
.. code-block:: pascal
|
|
|
|
function LoadBitmap(Path : string) : integer;
|
|
|
|
Load a bitmap from a path to a file. Known formats are .bmp and .png. (Possibly
|
|
others, don't know for sure)
