Hello, I need to know the disk size of an image, I calculate it using the following formula:
Disk size=( sizex*sizey*bits per pixel)/8 =memory size without compression But when the image is compressed on disk it occupies less and the size in memory is much larger, is there some method in the C++ GDAL API, to obtain the size on disk, size on memory, or the compression factor? Example: SizeX: 60416 SizeY:38656 Bits per pixel:24 Size memory= (60416*38656*24)/8=7.006.322.688 bytes Size disk=2.137.644.631 bytes The format image is COG - Cloud Optimized GeoTIFF generator, and has JPEG compression Thanks and regards ________________________________ [https://www.aplitop.com/descargas/firma1.jpg] Elena Ruiz Sofware Development & Technical Support Tel. +34 952 43 97 71 er...@aplitop.com Sumatra, 9 - 29190 M?laga (Spain) www.aplitop.com [cid:SocialLink_Facebook_32x32_a745adb8-c250-4372-8480-e77f503dad3d.png]<https://www.facebook.com/AplitopSL/> [cid:SocialLink_Twitter_32x32_858247f6-9d4a-4740-a6b3-9b5ebfd98a97.png] <https://twitter.com/aplitop> [cid:SocialLink_Linkedin_32x32_154d63de-bf68-468f-9eb0-ffed102fac77.png] <https://www.linkedin.com/company/aplitop> [cid:SocialLink_Youtube_32x32_0dea15dd-3774-4086-be9d-f62560b70c86.png] <https://www.youtube.com/user/aplitop> In accordance with the provisions of the European Regulation of Data Protection 2016/679 (Reglamento Europeo de Protecci?n de Datos 2016/679), we inform you that the data and the information you provide us through this medium will be used by APLITOP, S.L., with C.I.F.
