Features

• Optimize memory usage and improve performance
• Add useImageCountAsMaximumLevel parameter
• GPU based resample

Fixed

• Tentatively solved the boundary anomaly of the bilinear methods #35
• Single render dont request more than one band
• Bilinear resample dont handle nodata
• GeoTIFF workpool setting

Thanks

Thank you to the new contributor @RogerWQH2023 for his excellent code!

Features

• New configuration item "resampleMethod", supports new bilinear resampling method, thanks to @TheMrCam #34

Fixed

• Reduce canvas width for Firefox WebGL support @TheMrCam #32
• Swapped sourceWidth & targetWidth in reprojection() @TheMrCam #34
• stringColorToRgba() used green for blue, potentially missing a whole band of data. @TheMrCam #34
• No more any @TheMrCam #34
• Fixed typo of ResampleDataOptions @TheMrCam #34

Thanks

Thank you to the new contributor @TheMrCam for his excellent code!

Features

• After zooming in to the maximum level of COG, the image will not be distorted.
• Added the workerPoolSize parameter to control the number of threads in the resampling method's work pool, defaults to the number of CPUs available. When this parameter is null or 0, then the resampling will be done in the main thread.

Fixed

• useRealValue and domain parameters together cooperate with effectiveness.
• Fixed discrete rendering errors, 4 decimal places of render precision support.
• After zooming in, the image does not use geotiff's resampling method, and custom cropping and resampling methods are used to ensure the true values and coordinates of the corresponding TIFF. #30

Break Changes

• Removed resampleMethod from constructor options.

Thanks

Bug Fixed

• Compatible safari.
• Fixed native single tiff file range request error.

Features

• Add useRealValue parameter to determind if use tiff's real value to set the colors.

Bug Fixed

• Fix the issue of incomplete display of longitude lines across 180 degrees for non 4326/3857 projection TIFF.

Bug Fiexd

• Auto delete url in options when use fromUrl
• Support reverseY tiff

Breake Changes

• projFunc parameter need pass project and unproject functions to handle other geographic coordinate system, but compared to version 2.8.0, the order of two functions needs to be swapped.

Features

• add colorMapping options #19
• [Experimental] More accurate reprojection methods for handling non-3857, 4326 projections #16

Thanks
