Image Info

The 'File Format' property displays the type and MIME type of the primary image file for this Batch Page.

Usage

• Use this property to verify the file format (e.g., TIFF, JPEG, PDF) and ensure compatibility with downstream processes.
• The MIME type is included for integration and export scenarios.

> Example:
> TIFF image: Tagged Image File Format (image/tiff)

Can be one of the following values:

The 'Pixel Format' property indicates the color depth and channel arrangement of the image data (e.g., 1-bit binary, 8-bit grayscale, 24-bit color).

Impact

• Determines how the image is displayed and processed in Grooper.
• Affects available image adjustments and compatibility with certain activities (such as OCR or export).

> Note:
> The pixel format is set during image import or processing and cannot be changed directly from this property.

The 'Size' property shows the dimensions of the image in pixels, formatted as Width x Height.

Usage

• Use to confirm the resolution and aspect ratio of scanned or imported pages.
• Important for verifying that images meet requirements for extraction, review, or export.

> Example:
> 2550 x 3300

The 'Logical Size' property displays the physical dimensions of the image as it would appear when printed or displayed at its native resolution.

Calculation

• Computed as Width / ResolutionX and Height / ResolutionY.
• Useful for confirming that scanned pages match expected paper sizes (e.g., 8.5" x 11").

> Example:
> 8.50" x 11.00"

The 'Resolution' property indicates the image's dots per inch (DPI), which affects print quality and scaling.

Usage

• High DPI values (e.g., 300 or 600) are recommended for OCR and archival.
• Mismatched X and Y resolutions are displayed as ResolutionX x ResolutionY DPI.

> Example:
> 300 DPI or 300 x 600 DPI

The 'Bit Depth' property shows the number of bits used to represent each pixel in the image.

Impact

• Higher bit depths allow for more color or grayscale levels.
• Affects file size, image quality, and compatibility with certain processing steps.

> Common Values:
> - 1 (binary)
> - 8 (grayscale)
> - 24 (color)

The 'Compressed File Size' property displays the size of the image file as stored in Grooper, after compression.

Usage

• Useful for monitoring storage usage and troubleshooting large images.
• May vary depending on the file format and compression settings.

> Example:
> 45,000 bytes

The 'Uncompressed Image Size' property shows the calculated size of the image data before compression, based on pixel dimensions and bit depth.

Usage

• Helps estimate memory requirements for processing or exporting images.
• Useful for comparing with the compressed file size to assess compression efficiency.

> Example:
> 8,415,000 bytes

The 'Compression Ratio' property indicates how much the image file size has been reduced by compression, shown as a ratio (e.g., 4:1).

Usage

• Higher ratios indicate more efficient compression.
• Useful for balancing image quality and storage requirements.

> Note:
> If the compressed or uncompressed size is zero, the ratio is shown as 0.
