Not an issue. Just a quick question. I have successfully managed to run 64x64 gif Animation example code. But when I try to run 128x64 gif on 4 chained 64x32 panels . Then it only playing animation in 64x64 area rest 64x64 panel area is blank. How do I could run 128x64 animation? There is no option I am able to locate to change gif width and height in neoconfig.h file. Any help in this regard will be appreciated. about animatedgifs

glad you got it working. To be fair, there are 2 different codebases

1. neomatrix
2. the gif code
   so indeed they need to be configured separately and correctly for everything to work :)

You're looking for gif_size:

AnimatedGIFs/neomatrix_config.h

Line 151 in 179a2d6

#define gif_size 64

I think the library expects square gifs, so you'd need to decode a 128x128 gif and use the OFFSETY as shown in

AnimatedGIFs/SimpleGifAnimViewer/SimpleGifAnimViewer.ino

Line 7 in 179a2d6

int OFFSETX = 0;

Let me know if that works and I'll close this

Thanks Marc Merlin for very quick response. Please give me few days for this to work on your suggestion. I will update you with in next week.

Many Thanks. :)

Hi MarcMerlin,
Thank you so much for your suggestions, but it was my dumb mistake. Rectangular gifs are also working smoothly.
I was doing following mistake.
In https://github.com/marcmerlin/AnimatedGIFs/blob/master/neomatrix_config.h file I was passing direct pixels count in
const uint8_t kMatrixWidth = 128; const uint8_t kMatrixHeight = 64;

But it works well when I passed Tile size first then total number of Tiles in horizontal and vertical. Actually
I was thinking , these configuration was for NeoMatrix not for SmartMatrix. But In reality these variables are also used for mapping smartMatrix kpanels.

`const uint16_t MATRIX_TILE_WIDTH = 64; // width of EACH NEOPIXEL MATRIX (not total display)
const uint16_t MATRIX_TILE_HEIGHT= 32; // height of each matrix
// Used by LEDMatrix
const uint8_t MATRIX_TILE_H = 2; // number of matrices arranged horizontally
const uint8_t MATRIX_TILE_V = 2; // number of matrices arranged vertically

// Used by NeoMatrix
const uint16_t mw = MATRIX_TILE_WIDTH *  MATRIX_TILE_H;
const uint16_t mh = MATRIX_TILE_HEIGHT * MATRIX_TILE_V;

/// SmartMatrix Defines
#define COLOR_DEPTH 24         // known working: 24, 48 - If the sketch uses type `rgb24` directly, COLOR_DEPTH must be 24
const uint8_t kMatrixWidth = mw; //128
const uint8_t kMatrixHeight = mh; //64`

Many Thanks again for your quick support and nice work.
Regards,
Harpreet
