Viewing Animated GIF files

[bluedevil]

Hello people;
I have attached a project which loads an animated GIF using AniGIF library.
We should include the library

Code Select Expand

Include AniGIF.inc
IncludeLib AniGIF.lib
PUBLIC hInstance
Very important to declare hInstance as PUBLIC!!

Under Window procedure call two functions

Code Select Expand

PencereIslemi proc hWin:HWND,uMsg:UINT,wParam:WPARAM,lParam:LPARAM
invoke InitAniGIF ;Starts animation
mov eax,uMsg
.if eax==WM_INITDIALOG

              .
              .
              .
              .


.elseif eax==WM_COMMAND
              .
              .
              .
              .
.elseif eax==WM_CLOSE
              .
              .
.else
mov eax,FALSE
ret
.endif
invoke TerminateAniGIF ;HERE terminates animation
mov eax,TRUE
ret

PencereIslemi endp

Very important part :

Code Select Expand

#define logoGif 501
logoGif RCDATA    DISCARDABLE "Res/nelieltransform.gif"
  CONTROL "#501",aniLogo,"AniGIF",0x50000000,6,3,333,184,0x00000000
You have to write down "AniGIF" to Control section
And you have to define GIF as RCDATA


I want to ask is there any other options to achieve this goal without using these external -AniGIF- libraries?

@jj2007 you have included executables several times to forum. Bu you didnt share any source codes about this issue. Are you also using this libraries? If not can you share any sources with me?

Thanks for all =)

Because of the GIF file the zip file size  is ~700kb So here is a link to Github and Zippyshare

@jj2007 you have included executables several times to forum. Bu you didnt share any source codes about this issue. Are you also using this libraries? If not can you share any sources with me?

No, I use only the built-in Windows library GdiPlus. Here is a source:

guiTimerMs=50            ; more is slower
GuiParas equ "Simple GIF viewer", w240, h200
include \masm32\MasmBasic\Res\MbGui.asm      ; part of MasmBasic

Event Paint
  .if CL$(?)
      GuiImage CL$(), fit      ; drag an animated gif over the exe
  .else
      GuiImage 100, fit      ; or show tweetie from the resources
  .endif
GuiEnd

Full project attached, needs MasmBasic, of course.

\masm32\MasmBasic\Res\MbGui.asm is a public part of MasmBasic; the rest is closed source, but I could give you a personal exclusive license to disassemble the closed part, if you give me a good reason

For example, you could insert an int 3 into line 15572 of \Masm32\MasmBasic\MasmBasic.inc ;)

1. As a MASM32 coder i cannot understand your way of codes. In my MASM directory i have a MasmBasic directory too. But it says:

; The smallprint: this library is provided "as is", and the usual disclaimers apply.
; This help file refers to MasmBasic version 4 October 2012
; -----------------------------------------------------------------------
include \masm32\MasmBasic\MasmBasic.inc   ; this line substitutes include \masm32\include\masm32rt.inc

Is this old or very old version?
2. What is .ASC file doing exactly?
3. Generally hutch-- gives more pure assembly samples. But i always open to new knowledge. But here i have 2 issues.
3.a. I want to learn assembly, all syntaxes, rules, constants and everything. And in a very low-level way
3.b. I want to use RadASM as an IDE because i am the guy translated it in Turkish so i know every part of it.
4.When i see your code above i cannot implement that inside my own code :( Because i cannot understand what GuiImage does, what CL does and what $ does after CL?
5.At the end there must be a windows API but i still couldn't get there :(

Almost five years old. Incredibly old. How old is your current smartphone? The current MasmBasic version is dated 12 May 2017. But caution, installing MasmBasic is incredibly complicated. Well, actually not that complicated, maybe installing GCC or VS Community can give you even more headaches ::)

2. What is .ASC file doing exactly?

Assembler Source Code. Extract AnimatedGifViewer.asc and Tweetie.gif to any folder, then open the *.asc in \Masm32\MasmBasic\RichMasm.exe and hit the F6 key. The two files in the zip are the complete project.

3. Generally hutch-- gives more pure assembly samples. But i always open to new knowledge. But here i have 2 issues.
3.a. I want to learn assembly, all syntaxes, rules, constants and everything. And in a very low-level way

Hutch is a very good at low level assembler, but he is equally good at writing macros and high-level library functions, see \masm32\help\masm32.chm

The question "is pure low level assembler better than using macros?" is very important in the early stages of learning. Later on, you will still be able to write low level assembler, but if you don't use macros, you will never go significantly beyond the hello world proggie stage. If you wonder what "significantly" means: The source of the RichMasm editor is currently close to 20,000 lines. That is a medium size program. Theoretically, one could write such a program in push push call style, have fun.

3.b. I want to use RadASM as an IDE because i am the guy translated it in Turkish so i know every part of it.

It should be is possible*) to use MasmBasic from RadASM - after all, it's assembler, in the sense of: ML.exe can digest a MasmBasic source, from version 6.15 onwards. I haven't tested it, though (and I prefer HJWasm for building my stuff). Has anybody tested using MB in RadASM?

4.When i see your code above i cannot implement that inside my own code :( Because i cannot understand what GuiImage does, what CL does and what $ does after CL?
5.At the end there must be a windows API but i still couldn't get there :(

There is a MasmBasic manual, and there is one for OllyDbg, too.

*) RadAsm assembles the source without problems, but convincing the IDE to add the resource and compile it is a major challenge In the end, I gave up with the *.rc file, instead I copied the rsrc.res from the MasmBasic folder and changed the linker's commandline by hand, adding rsrc.res. The full RadASM project is attached.

a short demonstration using Gdiplus. See msdn for deatils of the used functions. Requires foo.gif in current dir and cmd option /Zp8

BTW: What has happen to this forum? "Use masmbasic" is now the accepted default answer to any upcoming question?

i remember there was static gif lib, no ani gif lib.

OP asked explicitly how I did it. Apart from this post, I made a quick check and found out that my last 28 posts had nothing to do with MasmBasic. So your remark proves that you are German and nothing else. Btw you should try MasmBasic, much faster than C and (no) [ugly] {brackets} or se;mi;co;lons;  8)

[fearless]

and cmd option /Zp8

Hi qWord, thanks for the example, just wondering why the /Zp8 is required? is it some alignment with data structures or for the gif file. Thanks in advance

[HSE]

Hi qWord!

Without /Zp I have a crash in:

Code Select Expand

        mov eax,DWORD ptr [ecx + DWORD*eax]
in theory is a 4 bytes problem. And work perfect with /Zp4  :t

[hutch--]

qword,

I am not sure why but after building it with the /Zp8 option and placing an animated gif in the same directory, it builds with no errors but will not run. Ends up in memory but nothing shows.

[qWord]

just wondering why the /Zp8 is required?

It the default structure member alignment in Win32 and should be always used to avoid strange errors. For most structures it has no effect because of their layout. In the above example it is the PropertyItem structure that has a WORD-sized member breaking the alignment of the following pointer (and yes, for this structure also Zp4 works, because there are no 64 bit width members in it)

OP asked explicitly how I did it.

He explicit ask how do it with plain WinAPI.

Apart from this post, I made a quick check and found out that my last 28 posts had nothing to do with MasmBasic.

just ignoring the several thousand other post you did with more or less "advertising".

So your remark proves that you are German and nothing else

Yes Mr. "I know the answer, but I won't give it to you"

[qWord]

I am not sure why but after building it with the /Zp8 option and placing an animated gif in the same directory, it builds with no errors but will not run. Ends up in memory but nothing shows.

strange - can you upload the EXE?

[qWord]

Attached my build.

[hutch--]

Just tried your build, will not run on my Win10 64 bit.

I have attached the source and how I built it and used your GIF file.

I could not get your window to start so I put all of your GDIP code in another window but it was looking for code that was not available. Are you using a special GDI plus include file ?

[qWord]

Your build works fine on win7x64

I guess there is some incompatibility in my code - would require to analyze the return values of the GDIP functions. I will try it later with a Win10 dev VM.

Are you using a special GDI plus include file ?

Actual not.
