Specifies the mapping between JPEG 2000 Capture and Display resolutions and ImageGear DIB resolution.
IG_JPEG2K_RESOLUTION_MODE_PREFER_DISPLAY | On image loading, use Display Resolution if it exists, otherwise use Capture Resolution if it exists, otherwise leave DIB resolution undefined. On image saving, write DIB resolution to the file as Display Resolution; write Capture Resolution value from metadata, if it exists. |
IG_JPEG2K_RESOLUTION_MODE_PREFER_CAPTURE | On image loading, use Capture Resolution if it exists, otherwise use Display Resolution if it exists, otherwise leave DIB resolution undefined. On image saving, write DIB resolution to the file as Capture Resolution; write Display Resolution value from metadata, if it exists. |
IG_JPEG2K_RESOLUTION_MODE_USE_DISPLAY | On image loading, use Display Resolution if it exists, otherwise leave DIB resolution undefined. On image saving, write DIB resolution to the file as Display Resolution; write Capture Resolution value from metadata, if it exists. |
IG_JPEG2K_RESOLUTION_MODE_USE_CAPTURE | On image loading, use Capture Resolution if it exists, otherwise leave DIB resolution undefined. On image saving, write DIB resolution to the file as Capture Resolution; write Display Resolution value from metadata, if it exists. |
IG_JPEG2K_RESOLUTION_MODE_LEGACY | Same behavior as was used by ImageGear v.16.0 and earlier. On image loading, use Capture Resolution if it exists, otherwise use Display Resolution if it exists, otherwise set DIB resolution to pixel per meter equivalent of 72 dpi. On image saving, write DIB resolution to the file as Display Resolution; write Capture Resolution value from metadata, if it exists. If DIB resolution is undefined, save Display Resolution as pixel per meter equivalent of 72 dpi. |
