Excellent idea
thank you for sharing

Does this require the new beta version of PB or can I run it with version 5.50?

Hi boyoss,

Thank you for your comments.

------------------------------------------------

Hi BasicallyPure,

The examples should work in any version of PureBasic, but may require some minor changes due to PureBasic Constants, etc. not existing in earlier versions of the IDE

Thanks JHPJHP

Hi Kwai chang caine,

You're very much welcome.

----------------------------------------

Updated:
- gif_decode.pb
-- modified the way transparency was handled
- gif_detail.pb
-- returns all available GIF information by frame

NOTE:
- this toolkit does not use the PureBasic GIF decoder
- gif_encode.pb is still unfinished (missing the LZW Encode algorithm)
- when time permits, will include a GIF to Spritesheet utility

Hello JHPJHP

Thanks for sharing your great works

I have try the extract and the result if strange, show by yourself

The first image extracting with your code



The second image extracting with your code
And nearly all the next images extracting with your code is like the second image



The first image extracting with JASC animation shop



The second image extracting with JASC animation shop



With JASC all the images is perfect

Hi Kwai chang caine,

Thank you for your post.

The example gif_extract.pb is working as expected...
- this can be tested using the example gif_animate.pb; combine the extracted frames into an animated GIF

Animated GIFs:

Chapter 17 of Learning Web Design, 2nd edition wrote:The optimization process saves only the pixels that change from frame to frame and throws out redundant pixels.
The result is a big savings in file size with no change in the animation’s appearance.

NB*: I will add an option to the soon-to-be-released GIF Toolkit utility, to save layered images as individual frames.

----------------------------------------------

Updated:
- gif_decode.pb
-- modified Disposal Method
-- modified DecodeLZW Procedure

Aaaaah ok !!! excuse me for disturbe you for nothing
I have a little bit thinking to that when i have see the result, but like JASC save all the image, i believe it's a problem

It's right the picture are merveillous, it's the rolls royce of the GIF i'm in the paradise

So thanks again for your splendid works, like all the others of JHPJHP

On the contrary, you are a very helpful member of this forum who not only takes the time to test the various code contributions, but also provide valuable feedback. Thank you

I am looking forward to the Sprite Sheet tool
In itself, a sprite sheet is the better GIF
Much more flexible and easier to handle

Hi walbus,

I like the package aspect of a GIF, but it does have some drawbacks.

Updated:
- GIFToolkit.pb: GIF Toolkit GUI (currently only formatted for Windows, but is cross-platform)

This is an unfinished product, but should give you an idea of where I am heading...
- most of the backend scripts have already been written (see the scripts folder)
- the top GIF player will display the animation
- each button will display an area with additional settings
- the bottom filmstrip will display individual frames, controlled by the above trackbar

Yes, with a filmstrip looks good

Hi walbus,

Had a couple of hours today to work on the GIF Toolkit; currently only the thumbnail player and transparency coloring are completed.
- double-click the thumbnail player, while a GIF is loaded, to open the GIF in its original size

NB*: All the previous examples are still available from the scripts folder.

Sincerely thanks for this great compliment, who have again more value when it come from a great master of programming like you
