HI, I´m a newbee,
I have read some tut´s but I´m searching for a possibility to "draw" a animated Gif to a window.
Til now i have explore some expirience with Bitmap format and JPG.
But til now i cound´n found any tut of Gif.
How can I realize?
Many thankx in advance.
Avalon
Avalon,
I am sure that this is very possible but it is not anything that I am able to do very well. I grew up in a nongraphical environment and am a late player in that arena. Why don't you send an email to Donkey? He is, I think, one of the acknowledged professionals in this area and is very approachable. He has been having some network problems that he has gone a long way towards solving. But he might miss this post.

This link may help. :)

Many thanks,
first of all, i´m sorry for my poor english, ::) i´m doing my best to explaine.
AniGiff viever is very well, :U
BUT
it needs / loading an AniGIF.dll .
I need only one PRG / exe file no dl other things.
as compact as possible.
how can be made reverse dll and take only the thinkg i need?
or intergrate dll in main.
Avalon
Avalon,
Let's not talk about reversing.
Paul
FYI, our ObjAsm32 Package has a GIF object that will load and display GIF's for you...

Who would ever need to reverse an
open source library? ::)

Hi at all,
reverse means to intergrate the code to main NO more.
that I wand to do is not to "load" some picture no i wand to display Animated Gif on windows.
Avalon.
PS I´m sorry but I could not found the code for the displayer.
The library uses the OLE apis to decode each frame in the GIF file (take a look at AniGif.asm, not GifViewer.asm). Perhaps what you want is the GIF file format instead?
Avalon,
Are you primarily interested in the animation or the file type. If you do not mind working with bitmaps as long as you get the animation that you desire; I have attached something that has been developed by William Cravener that is way cool! As an example it is very easy to grow from.

Great example, thanks Paul! :U
Animate is a great example how to do :U :U :U
Now my questions:
1. how can I transfer my Gif file to bitmap? (sceene by sceene or frame by frame the same)
1.1 How can i export "only" the bit´s and byte in writting format e.g. (textformat)
Frame 1,
Byte 00,FF,80,90,00, ...
Frame 2
and so on
Colortab and so on
2. exist a function to change "only" the color map (RGB)?
3. The file will be going very "huge" is there a possibility to "compress" it with e.g. Hufmann and decompress direct to memory?
What I wanna do:
Frame 1
Frame 2
Frame 3
.
.
.
frame 9
and so on
The frames has the same y and x size
they have the same color tab
to save memory (filesize) to put all frames to gether only onetime save the colortab and compress with huffmann
decompression:
allocate memory for each frame
and writte directly to Memory ==> endcompressed dates and colortab
I remember this way on 68H000 prz. (Hardware scrolling with bitclipp the same procedure)
My question to change the "colortab" is in this way (the fastes way to chance background)
You can make in this way some nice effects. (scrolling colors)
Best regards,
Aladin
Avalon,
I am pretty much an afficiando of Paint Shop Pro. There is a shareware version available while you are testing and deciding if you want to buy it. Take an animated GIF that is owned by you, open it up in the Animation Wizard (a separate program that comes with the package. Select all the images and export tham to PSP. Now you can do a batch conversion from GIF to bitmap. The option is in the File menu. For now, accept all the defaults and do the conversion. Now you must save all the bitmaps.
Once that is done, you can use a tool, a part of masm32, IIRC, to dump each bitmap as a rcdata thing.
Paul
BTW: PSP has a much gentler learning curve than some other products.
Avalon,
As far as manipulating the color bits and what not once the dump has occurred? This is outside of my field of expertise. I think I have given you enough to get started. When you finish the prelim stuff, you can post a question to one of the graphics gurus.
Paul
AFAIK GIF's are just RIFF files, it should be possible to decompress them programatically fairly easily. If you like you can email me a GIF that you want to use and I'll take a look at displaying it.
HI,
many thanks for all repies.
Till now i don´t know thich way is the best:
the results until now:
My sample Gif was 25 KB
18 Frames in bmp each frame 10 KB (with colortable) sumary: 180 KB
in PNG and JPG near the same results. near 135 KB
At the moment I´m study a sample how to compres / decompres GIF files on the fly, but i do not realy unerstand the source (print and studi :toothy)
We will see tomorow.
Avalon
There is also UPX, http://upx.sourceforge.net/ - that seems to work well on bloated files. :U
Hi Mark,
hi at all,
it´s a good idea to compress the exe file, but
first of all i will make compact code
then compact exe :green
The project will be realized in
Take GIF format ==> decompress on the fly ==> make different bitmaps in memory (each frames) ==> bitblt bitmaps (Animation)
After i dump the GIF (thanks to Paul :U) i have separate the graphic information and color and so on information overhead from the gif and save only the graphic data to a file.
Now i can include it separately. (This part is ready no changes)
I was surpriced what kind of information is stored in a GIF file sometimes is like M$ there is a lot of rubbish inside so i can delete some bytes, grat help was the side http://www.wotsit.org/
I´m thinking abaut include alpha cannel information make from 24 bit convert to 32 bit ( RGB ==> ARGB by 8 bit each channel)
We will see if it´s works. :cheekygreen:
The size of code is at the moment 46 kb (without compression Mark :green)!
If somebody has some good ideas, let me know.
Avalon
