When used with an image which is an evenly-sized multiple of the tile size, the zoomify code incorrectly assigns an image size of [0,0] to the rightmost and/or bottom tile images. Even though the images are in the DOM and positioned correctly, they do not display (because, of course, they have a size of zero).
The problem is due to sizing code in Zoomify.js, getImageSize().
The original code is:
/* getImageSize returns size for a particular tile. If bounds are given as
* first argument, size is calculated (bottom-right tiles are non square). */
var w = this.standardTileSize;
var h = this.standardTileSize;
if (x == this.tierSizeInTiles[z].w -1 ) {
var w = this.tierImageSize[z].w % this.standardTileSize;
};
if (y == this.tierSizeInTiles[z].h -1 ) {
var h = this.tierImageSize[z].h % this.standardTileSize;
};
When (tierImageSize[z].w == standardTileSize), the modulo result is 0, not standardTileSize.
A possible fix is:
if (x == this.tierSizeInTiles[z].w -1 ) {
var w_1 = this.tierImageSize[z].w % this.standardTileSize;
if(w_1 != 0)
w = w_1;
};
if (y == this.tierSizeInTiles[z].h -1 ) {
var h_1 = this.tierImageSize[z].h % this.standardTileSize;
if(h_1 != 0)
h = h_1;
};
