ofn-tiles & ofn-export-layers

It took me a while to understand this.

The explanation given in the previous post was excellent and clarified my doubts!

"The coordinates of the tiles in a referential X,Y is really (column,row). So tileRC, to output the images row by row, goes (1, 1), (2, 1), (1, 2), (2, 2) and this increments the columns before the rows"

My question was about:

"the sequence number of the tile. The tileRC value increments the columns before the rows, and the tileCR value increments the rows before the columns."

Why did I think the sequence was reversed? Because the way I was looking at the process was different!

In the case of TileRC, I thought that the tiles from the first row were selected first, then those from the second row, etc. until the last row.
In the example in the image below, the order obtained from the Tiles is:
a1, b1, c1,d1 and e1 (first row), then a2, b2, ...,e2 (second row), etc.


In the case of TileCR, as shown in the image below, first the tiles in the first column were selected, then those in the second column, etc.
a1, a2, a3, a4 (first column); b1, b2, b3, b4 (second column), etc.


Hence my doubt.

Perhaps a matter of point of view (not regarding the process itself, as explained in the previous post):

In the TileRC of the image below, to output the images row by row, goes:

01- (1, 1), (2, 1), (1, 2), (2, 2) and this increments the columns before the rows.
02- As I see it: Take everything on the first line, then everything on the second line, etc.


For TileCR, goes:


01- (1,1), (1,2), 2,1), (2,2) and this increments the rows before the columns.
02- As I see it: Take the entire first column, then the second column, etc.
