Gdi+ Gif Animation Test

[guga]

Hi Guys

I made a small test to load icons (with and without transparency), jpg, animated gif, png (with transparency), and tifs using Gdiplus following the idea made by JJ and Marinus. Can someone please test to see if there is a gdi leaking happenning ?

The app will open a opendialog box twice. The 1st image you choose as the foreground (icon, jpg, gifs etc etc) and the second image (gif, ico, jpg etc) it will be displayed filing the whole window/control where the image is to be showed. Also you can freely resize the window and the background image will stretch according.

I tried to use only Local variables to make this work, rather the using global) all controled by a single structure filled in WM_CREATE message. (Used globally). So, i needed only one major Global structure to control all of this

Once you open the image, it will call to a function GdipCreateImageInfo that will setup the whole data necessary for the used structure (Which i labeled as GdipImageNfo).

Then all the rest of the functions relies only in WM_PAINT, while WM_SIZE and WM_TIMER, contains only few modifications of the variables used onto that structure.

Note: I´ll do the necessary extra comments about the usage of each of the functions later if the app is really working ok without any leaks and will update it here, ok ? :)

The attached code (Embedded inside the executable as usual) is something like this:

At WM_CREATE:

Code: [Select]


(...)
[AnimateFramePerSec: F$ 60] ;  Frames per second to be used in GdipCreateImageInfo to calculate and create a smooth animation. The value of  "3" in GdipCreateImageInfo is the Keyframe of the sequence of repeated images to be animated

; Simple equates used as flag representing how we want our image to be displayed
[GDIP_DRAWIMG_DEFAULT 0] ; Default view. So, the image is displayed as it is without altering his X, Y pos and neither affecting the original width and height
[GDIP_DRAWIMG_FILL 1] ; Fill all over tyhe control or window. The image will fill the window/;control where it will be displayed. Generally it can be used as a image background
[GDIP_DRAWIMG_AUTO_ADJUST 2] ; To be implemented yet.

    We are creating here the total amount of Time necessary to animate a Animated giff or tiff image. Instead allocating more memory or using extra gdiplus apis to get the delay time of the image, is better (and faster) do it directly on user command.
    On this way we can simply get the total amount of used frames and create an animation by scratch. We can set the Timer ID and also input the fps (Frame per second) we want our image to be animated and also we can set the wanted keyframe to make the animation be smoother, faster or slower.
The keyframe is only a repetition of images given a certain amount of time. It is used in video edition as well, so, on the same way as in videos, we can set this value to 3 or 4 to make the animation be ok without worring in allocating extra memory or using extra gdiplus apís.

    We have 29.970 per 1000 seconds =
    2.9970 frames per 100 miliseconds
    since we have 3 repeated frames it means we have
    100/2.9970 = 33.3667003....frames on eac interval of 33 miliseconds, therefore:
    3*33.3667003 = 100.100 miliseconds per each keyframe

Fantastic 
Just yesterday I was reading posts about this subject.

I found a "temporal" solution including the icon (the gear) in a button 

I will study your code!!

Tks, a lot HSE !

Great idea using it as a Button icon


Did you tested the example i posted ? Is it working ok or is leaking etc ?


Btw...If you don´t have RosAsm, i´m attaching it here to you see the full sources of this test. (The function ImgPaintP is the main responsible for painting  the whole image. It was inspired in the one JJ build but it was too complex for me, so i tried to simplify it the best i could - I´ll change the name of this function later, btw  )

If it is ok without leaking, i can then add it to RosAsm itself on the routines i´m fixing for the resources editor and may upload a new version as soon i finish fixing all of those small things.

[HSE]

Your example work well, perhaps a little fast the animation.

I have RosAsm!

I read you are using GdipImageDraw, that makes me to remember that there is some Draw functions in GDI and ... there is DrawIcon!

Just replacing the button with a small window:

[jj2007]

Can someone please test to see if there is a gdi leaking happenning ?

No leaks - compliments

[Siekmanski]

Looks good.

I read you are using GdipImageDraw, that makes me to remember that there is some Draw functions in GDI and ... there is DrawIcon!

Just replacing the button with a small window:

Hi HSE, yes i tested that with DrawIcon too, but it was not working for transparent icons on the tests i was doing and neither for png and other kind of images, that's why i choose to use GdipImageDraw to make it a general usage drawing image routine. (That can also be used to draw webp files, btw).

Glad to see you are using RosAsm I plan to make new updates soon. Recently i suceeded to implement SSE3 and SSE4 in the assembler, disassembler and debugger routines and started cleaning the whole code. I suceded to fix some old old issues in memory management and got the way to make the encoder and decoder be used as a standalone libraries (dlls). Now i´m currently working on the resources editor to fix whatever i can, and eventually build a new one based on the WizardsForm

The main problem was that hundreds of variables in RosAsm were being reused several times by different functions for different purposes and identifying which one is which is a true hell

The good news is i created a couple of libraries to start making it work as standalone: FastCRT.dll, RosMem.dll, IconEdit.dll and i´m allowing to use libwep.dll (from google) to be used in the resources images so we could also import and export webp files inside the resource section 

About the speed on this tests. It maybe fast because some gifs are encoded in different ways. Some of them have more frames per scenes then others.

Try reducing the fps to 29.970 or 25 and changing the keyframe to 4 instead of 3. It may result on a delay time of something around 100 ms (that will be passed to WM_TIMER message) that is used in many gifs as well. Like this:

[AnimateFramePerSec: F$ 29.970] ; or 25

and change the keyFrame value used in GdipCreateImageInfo as below (marked in red)

        call GdipCreateImageInfo D@Addressee, 0, 0, GDIP_DRAWIMG_DEFAULT, IDC_TIMER1, AnimateFramePerSec, 4, D$RsrcIconNfo.IconDataPtr, D$RsrcIconNfo.Size, GdipImageNfo1
        call GdipCreateImageInfo D@Addressee, 0, 0, GDIP_DRAWIMG_FILL, IDC_TIMER2, AnimateFramePerSec, 4, D$RsrcIconNfo.IconDataPtr2, D$RsrcIconNfo.Size2, GdipImageNfo2

No leaks - compliments

Looks good. 

Tks a lot, guys. I couldn´t do it without you both 

Glad to know there´s no leak. Now i can move on and implement it in RosAsm in order to try finish fixing the resources editors using this new functions to display the images to be used in the resource section of a file

Hi guga,

Nice job

Does your application depends on vcruntime140.dll?  I had to find and add this DLL.

[HSE]

Hi Guga!

Glad to see you are using RosAsm

I have RosAsm, Fasm, Yasm, but I only use ML, UAsm and AsmC. Most projects rely on SmplMath, and some of my own critical macros only work with AsmC.

[AnimateFramePerSec: F$ 29.970] ; or 25

That was 60 in your file.
Look nice with 25 and 4 

[guga]

Hi guga,

Nice job

Does your application depends on vcruntime140.dll?  I had to find and add this DLL.

Tks Vortex

No,  It´s was not suppose to use vcruntime140.dll. If it is asking for it, i can only think that maybe libwebp.dll needs it. 

Tks for reporting, i´ll change FastCRT.dll in order to use libwebp (That calls to this other dll) dinamically with LoadLibrary rather then a direct dll call as it is already

Here´s vcruntime140.dll to you test

[guga]

Btw...Talking about libwebp. How to force VisualStudio to compile a gnu c project ?

Libwebp was meant to be compiled with GNU C make. So, maybe teh better would be compile it with VisualStudio, but i dont know how o do it. Can someone pls try to convert it using VisualStudio as a compiler ?

I cannot upload the files here, because they are big

The link containing the source code is:

https://developers.google.com/speed/webp/docs/compiling

Btw...The last version 1.1.0 seems to have both x86 and x64, so, if someone could allow it to compile wieh x86 rather then x64 it would be better for people with older machines also uses it without problem.

[guga]

New test

This time added a small Text on it and also the color of the background is painted with a modern color.

Probably it sill not leaking, but if someone could test for leaking it would be great :)

Note: The additional dlls are attached on the 1st post

[Vortex]

Hi guga,

Your application depends on two extra DLLs :

Code: [Select]

\PellesC\Bin\podump.exe /IMPORTS AnimGifTest5.exe | findstr ".dll"
.
.
        FASTCRT.dll
        ROSMEM.dll
.
.
Could you attach those DLLs? Thanks.

[guga]

Hi Vortex

They were attached on the 1st post. I´m attaching it again 

Added also libwebp.dll and vcruntime140.dll (these two ones are needed for the webp files used in FastCRT.dll)


The FastCRT.dll i made uses google chrome libwebp (that uses the vcrxxx library). Later i´ll try to see if i can avoid loading libwebp.dll with a check for loadlibrary (Or eventually, create a full routine able to encode and decode webp files as well)

The main routine for painting a new color for the background is at CreateWorkingDCEx  and the one responsible to create the text i labeled as GdiTextPaint

I´m currently cleaning the code in order to try making it work with one single function at once.
