Help with ImageCompression

[Andrey Vakhtanov]

Good time!

I try to set some parametrs for image compression for networktask in version 1.8.2
Image format tiff

Code: [Select]

img_compress_def = PhotoScan_API.ImageCompression
img_compress_def.tiff_big = False
img_compress_def.tiff_tiled = False
img_compress_def.tiff_overviews = True
img_compress_def.tiff_compression = PhotoScan_API.ImageCompression.TiffCompressionDeflate
exportIUST_TIF_task.params['image_compression'] = img_compress_def

on stage generting task I get error

Code: [Select]

File "*****************/**************.py", line 1664, in DemOrthoExport img_compress_def.tiff_overviews = True
 AttributeError: 'Metashape.ImageCompression' object attribute 'tiff_overviews' is read-only
only for tiff_overviews attribute

Where is the problem?

Hello Andrey,

You should fix the first line in the assignment to:

Code: [Select]

img_compress_def = PhotoScan_API.ImageCompression()
Executing the line without the brackets in the end could "break" the Python interpreter in the current instance/thread.
