-
- All ControlPads are chained in a single-linked List.
- Remember to save the head-pointer to the List somewhere,
- because it's needed for free'ing the List.

- want to add more entries to the list, note that all entries have
- to be allocated with AllocVec() and delocated with FreeVec().

- NAME
- SVSUP_DisplayGfxBuffer
-
- SYNOPSIS
-
- ULONG SVSUP_DisplayGfxBuffer(struct SVSUP_DisplayHandle *disphandle)
- D0 -$9c A1
-
- FUNCTION
-
- This function allows displaying of GfxBuffers, e.g. for
- test-purposes.
-
- This will may you, if you simply want to check the results
- of self-created GfxBuffers or compare the results of
- a GfxBuffer-conversion via e.g. SVSUP_OnePlaneToBitPlane8.
-
- The following code is quite senseless, because it is much easier
- to use SVL_DisplayGfxBuffer() instead, but it demonstrates
- quite good, how this function may be used (and _this_ example
- definitely works ...) :
-
- ULONG GfxBufferShow(char *filename)
- {
- ULONG retval = SVERR_NO_ERROR;
- APTR handle = N;
- struct SVSUP_DisplayHandle *displayhandle = N;
-
- displayhandle = AllocVec(sizeof(struct SVSUP_DisplayHandle), MEMF_CLEAR|MEMF_PUBLIC);
- if(displayhandle)
- {
- SVL_GetGlobalDriver(&displayhandle->SVDriverNode, N);
-
- handle = SVL_AllocHandle(N);
- if(handle)
- {
- if(!(retval = SVL_InitHandleAsDOS(handle, N)))
- {
- displayhandle->WinIDCMP = IDCMP_MOUSEBUTTONS;
- displayhandle->ScrType = CUSTOMSCREEN;
-
- retval = SVL_ReadToGfxBuffer(handle, filename);
- if(!retval) retval = SVL_GetGfxBuffer( handle, &displayhandle->SVGfxBuffer, N);
-
- if(!retval && displayhandle->SVGfxBuffer)
- {
- retval = SVSUP_DisplayGfxBuffer(displayhandle);
- if(!retval)
- {
- if(displayhandle->Window)
- {
- WaitPort(displayhandle->Window->UserPort);
- }
- }
-
- SVSUP_UnDisplayGfxBuffer(displayhandle);
- }
- }
-
- SVL_FreeHandle(handle);
-
- }else retval = SVERR_NO_HANDLE;
-
- FreeVec(displayhandle);
-
- }else retval = SVERR_NO_MEMORY;
-
- return(retval);
- }
-
-
- The Handle has to be allocated and initialized before passing it
- to this function. After usage - and after calling SVSUP_UnDisplay-
- GfxBuffer() - it has still to be delocated.
-
- You do not need (or must) initialize all fields of the Handle
- structure, but set them to NULL, if you do not (or must not).
- It is suggested, that you'll use AllocMem/AllocVec() with the
- MEMF_CLEAR flag.
-
- Initialize at least the following fields :
-
- - Version (currently 4)
- - SVGfxBuffer (the GfxBuffer)
- - SVDriverNode (as returned by SVL_GetGlobalDriver)
-
- Optionally initialize the following fields :
-
- - WinIDCMP
- - WinFlags
- - ScrType
-
- After calling SVSUP_DisplayGfxBuffer(), but before
- SVSUP_UnDisplayGfxBuffer() you may use the following fields
- for read-only purposes ::
-
- - Window;
- - Screen;
-
-
- All values are used and have to be interpreted just like the
- corresponding parameters of the similar SVL_/SVO_ or SVD_
- function calls :
- If you do not supply values for ScreenType, WindowIDCMP and
- WindowFlags, default-values will be used instead.
-
- INPUT(S)
-
- displayhandle - a handle, as defined in "superviewsupport.h".
- Has to be allocated and initalized by the User !!
-
- RESULT
-
- NULL or a SVERR-Errorcode.

-

-
- All temporary buffers etc. will be delocated, then.
- The supplied GfxBuffer and the Handle itself will be left intact.

- SVSUP_FreeGfxBuffer

- D0 -$a8 A1
-
- FUNCTION
-
- Use this function to free GfxBuffers, which are not related to
- any SVObject-Handles.
-
- E.g. any of the SVSUP_ScreenToXXXPlane() and SVSUP_XXXPlaneToXXXPlane()
- functions produce GfxBuffer, which have to be given free either
- via separate FreeVec() calls for the ImageData-Buffer and for
- the GfxBuffer itself or just by calling this function and then
- forgetting about it.
-
- Do not try to free buffers, which will already be freed via the
- next SVL_FreeHandle call.
- These are Buffers, which are returned by SVL_GetGfxBuffer().

- gfxbuffer - a valid pointer to a "stand-alone" GfxBuffer
