Cairo

[jj2007]

This looks promising, I hope I'll find some time to explore Cairo:

include \masm32\MasmBasic\MasmBasic.inc         ; download
  Init
  Dll "\Masm32\Cairo\lib\x86\cairo.dll"
  Declare cairo_version
  Inkey Str$("This is Cairo version %i", cairo_version())
EndOfCode


This is Cairo version 11512

[Biterider]

Hello
I saw the opportunity to add something to this project and translated the header files with h2incX.
Since it worked fine, I share the result with those who want to experiment with Cairo.

Very good idea, biterider :t

Does it run on your machine? I get some errors:

EDIT: example compiled with PellesC 9

[Biterider]

Hi JJ
I was able to compile a test application changing some of the symbols that point to nirvana. It seems to be a leftover from the windows translation.
I commented them out and I could compile.
Since I'm using a variation of the WinInc project with the most recent header files, I had no problems with the @DefProto macro. If you are using another source, like "MASM32 windows.inc", you have to define your own macro. Here the original:

Code Select Expand

  ifdef _WIN64
    WIN_STD_CALL_CONV equ <fastcall>
    @DefProto macro ApiQual, ProcName, CallConv, NameSuffix, Params, DecorSuffix
      ifdif <CallConv>, <vectorcall>
        ??CallConv equ <fastcall>
      else
        ??CallConv equ <&CallConv>
      endif

      ifidn <ApiQual>, <DllImport>                      ;;Call [IAT], a bit faster
        TYPE_&ProcName typedef proto ??CallConv Params
        externdef __imp_&ProcName: ptr TYPE_&ProcName
        ProcName&NameSuffix equ <__imp_&ProcName>
      else
        ProcName&NameSuffix proto ??CallConv Params     ;;Call thunk (jmp [IAT])
      endif
    endm
  else
    WIN_STD_CALL_CONV equ <stdcall>
    @DefProto macro ApiQual, ProcName, CallConv, NameSuffix, Params, DecorSuffix

      ifidn <ApiQual>, <DllImport>                      ;;Call [IAT], a bit faster
        TYPE_&ProcName typedef proto CallConv Params
        ifnb <DecorSuffix>
          externdef WIN_STD_CALL_CONV _imp__&ProcName&@&DecorSuffix: ptr TYPE_&ProcName
          ProcName&NameSuffix equ <_imp__&ProcName&@&DecorSuffix>
        else
          externdef c _imp__&ProcName: ptr TYPE_&ProcName
          ProcName&NameSuffix equ <_imp__&ProcName>
        endif
      else
        ProcName&NameSuffix proto CallConv Params       ;;Call thunk (jmp [IAT])
      endif
    endm
  endif


I noticed, that the symbol naming decoration of the import library is not the windows standard, so you have to change the macro to fit to cairo.lib.
I did it and found that the loader had some problems resolving some addresses.
I reuploaded the files to the previous post with the uncommented symbols.

Tomorrow I'll try to generate my own import lib with windows native tools. We will see...

Thanks, Timo - that was actually the binary I was already using, it pops up on top for googling cairo windows binaries. Here is my first successful attempt:

  cairo_set_fill_rule(context, CAIRO_FILL_RULE_EVEN_ODD)
  cairo_fill(context)
  cairo_destroy(context);
  ; cairo_surface_write_to_png(surface, "test.png")    ; saves client area to disk
  cairo_surface_destroy(surface);
GuiEnd

When sizing, you can see the random colours generated. I ran it with a timer and MemState, no leaks detected.

Source & exe attached, including my Pelles C test case (which works only when in the same folder as the DLL... :()

The DLL is 2MB, too big to be posted here; but all you need is cairo.dll from the link you posted (download), which I suggest to save to \Masm32\Cairo\lib\x86\cairo.dll for those who want to follow this thread.

A problem with Declare

Sorry, I haven't updated the package for a while. Attached the new Declare version, to be inserted after the Dll line.

[HSE]

 :t Thanks.

[jj2007]

If you are successful in testing other Cairo functions, please post them. I am curious if this lib offers any advantage over plain Gdi or Gdi+.

Complete Cairo API

P.S.: Try inserting a MakePath/GuiDraw element (resizable!):

SetGlobals surface, context, double red, green, blue
MakePath 111, Bezier(150:0, 0:90, 0:120, 300:300)
MakePen hPenBez, RgbCol(200, 160, 160, 0), width 4, startarrow LineCapRoundAnchor, endarrow 12:9, inset 2

Hi
I got it working now after changing the calling convention!  ;)
I had to change the proto definition macro accordingly and all works fine now.

Attached is a demo that uses the code shown by JJ

Code Select Expand

Method CairoApp.OnPaint, uses esi, wParam:WPARAM, lParam:LPARAM
    local PS:PAINTSTRUCT, hDC:HDC, Rct:RECT
    local Surface:HANDLE, Context:HANDLE

    invoke cairo_destroy, Context
    invoke cairo_surface_destroy, Surface

    invoke GetClientRect, [esi].hWnd, addr Rct
    invoke DrawEdge, hDC, addr Rct, EDGE_SUNKEN, BF_RECT

    invoke EndPaint, [esi].hWnd, addr PS
    mov eax, TRUE
MethodEnd


To use the exe, put the cairo.dll in the same directory.

The rest is now experimenting with the API.

I reuploaded the modified include file set to the above post.

Your exe works fine, but the includes still throw numerous errors despite using this macro as you suggested:

[Biterider]

Hi JJ
Cairo.inc contains the macro used for prototyping (@DefCairoProto). The one I posted is the standard for Windows API, which does not apply here. Theoretically, you do not have to add anything special to the include files.

For the posted application I simply used:

Code Select Expand

include .\Inc\cairo-win32.inc


The .inc files include the required files. Some of them are part of the windows header files. This is the case for Cairo_ft.inc. Others include Windows.inc. I did not test it with the masm32 set of include files. Maybe there is an incompatibility.
I used UASM as an assembler.
I have not experimented with SVG or PDF backends yet. I hope I can spend some time this weekend to play with them.

You can PM me sending the errors you are seeing and the context of your application. 8)
If there is of any use, I cam post the sources of the demo application.

Regards, Biterider

Done.

That would certainly be interesting, thanks :icon14:
