Tiler is an XYZ tile creator written in C# (dotnet 6.0) that works on Windows, Linux, OSX. It can quickly process large images into XYZ tiles that can be used with leaflet/slippy/etc.
A transparent background is used to center the image into a square frame and subdivided for any output format that supports transparency. Consider pre-sizing your input image to a square size (to your preferred alignment) if you do not want your image centered. If you wish to use a different (unsupported) output format or naming convention create your own script to resave the format and name. The default naming format is {z}_{x}_{y}.png.
Tile size defaults to 256 pixels squared (matching the default of leaflet and slippy). 2n tiles squared are created for each zoom depth n.
Compiled binary (portable) versions are available in the binaries/ directory for Windows (x86, x64), OS X (x64), and Linux (x64, arm, arm64, musl-x64)
-
clone or download the repository
-
open the binaries directory, find the matching binary/architecture for your OS, drag-and-drop your image onto the appropriate executable file
-
your tiles will be created in a new folder in the directory with the original image
This usage of Tiler requires only the file name for the command line arguments - This style looks different so it can handle drag-and-drop in an explorer context
Tiler.exe <input image file>
or explicit option overrides can be set
Tiler.exe -input <input image file> [-size <tile pixel size>] [-zoom <max zoom level>] [-filename "output/{z}_{x}_{y}.png"]
- -zoom determines maximum zoom level/layers; if blank it will determine the correct maximum level
- -size determines the tile size in pixels, defaults to 256 (square)
- -output specifies an output directory, absolute or relative - do not include trailing slash
if no input is specified, the standard input stream is used to load an image
