Format for "projection" parameter in 1.6 Python API

[ashalota]

What is the new format for the projection paramter used in "exportRaster" ?

Previously I had set it as: Metashape.CoordinateSystem("EPSG::"+str(epsgCode)) , when using "exportOrthomosaic" in 1.5


I can't figure out how to translate this to the 1.6 API

I'm also having trouble understanding hwat happened to jpeg_compression.

Could you translate this 1.5 code into 1.6 please?

Code: [Select]

curChunk.exportOrthomosaic(path=orthoDirAndFilename,
                             region=regionBounds,
                             format=Metashape.RasterFormat.RasterFormatTiles,
                             image_format=Metashape.ImageFormat.ImageFormatTIFF,
                             projection=Metashape.CoordinateSystem("EPSG::"+str(epsgCode)),
                             tiff_compression=Metashape.TiffCompressionJPEG,
                             jpeg_quality=20)

Hello ashalota,

Output coordinate system definition in 1.6 for export raster:

Code: [Select]

export_proj=Metashape.CoordinateSystem("EPSG::"+str(epsgCode))
projection = Metashape.OrthoProjection()
projection.crs=export_proj
chunk.exportRaster(projection = projection)
Image compression definition:

Code: [Select]

compression = Metashape.ImageCompression()
compression.jpeg_quality = 20
compression.tiff_compression = Metashape.ImageCompression.TiffCompressionJPEG
chunk.exportRaster(image_compression = compression)

How does the region BBox argument get created? Looks like the old format: (xmin,ymin,xmax,max) does not work anymore.

Hello ashalota,

Please check the following example:

Code: [Select]

region = Metashape.BBox()
region.min = Metashape.Vector([x0, y0])
region.mфч = Metashape.Vector([x1, y1])
chunk.buildOrthomosaic(region = region)
