Exploring the Raster Preferences Dialog Box - MapInfo_Pro_Advanced

Display

The Display tab contains the following settings:

Color Table - The Color Table drop-down list enables you to set the default color look up table option for a raster. For continuous rasters that do not have information about color inflection points, this setting will be applied to when opened for the first time.
Display Transform - The Display Mode drop-down list enables you to display the raster file in one of the four modes:
1. Linear
2. Logarithmic
3. Equal Width Histogram
4. Equal Frequency Histogram
Enable Hill Shade - The Enable Hill Shade check box lets you enable or disable sun shading facility for a raster.
Sun Angle - The Sun Angle drop-down list lets you select the default angle of the sun when a raster is opened in a map window.
Sun Elevation - The Sun Elevation drop-down list lets you select the default elevation of the sun when a raster is opened in a map window.
Enable Sun Highlight - The Enable Sun Highlight check box lets you enable or disable sun highlighting facility for a raster.
Highlight Angle - The Highlight Angle drop-down list lets you select the default sun highlight angle when a raster is opened in a map window.
Highlight Elevation - The Highlight Elevation drop-down list lets you select the default sun highlight elevation when a raster is opened in a map window.
Generate Raster Overview Cache - This option generates the overview cache of the pyramid levels for a raster. If a raster is opened for the first time, it will take longer because the cache will also be generated. The drop-down list items represent the size of the input dataset. Depending on the number of cells in the input raster, the cache file will be generated.
Apply Changes Automatically - The Auto Apply Changes check box lets you enable or disable the auto apply control when coloring or applying hill shading on a continuous raster.
Show Band Unit - The Show Band Unit check box lets you enable or disable the unit of a band and its value.
Show Color table name - The Show Color Name check box lets you show or hide the color palettes name. When enabled, it will show the color palette name in English language only.
Enable Block Access - The Enable Block Access check box lets you enable or disable block rendering of the raster. If you want to generate underviews, you will need to enable this option.
Disable Alpha Channel - The Disable Alpha Channel check box lets you control the rendering of alpha channel in your raster data. By default, the rendering of alpha channel is enabled in MapInfo Pro Advanced.
Display Resampling Method - The Display Resampling Method option appears when the Block Access is enabled. It displays the list of Resampling methods. When enabled, it applies resampling algorithm. The raster images will maintain a smooth and high quality appearance even if you zoom in beyond the resolution of the individual pixels.
Legend Mapping - This option enables you to show legends for the raster on the map.
Interpolate - The Interpolate check box lets you set the default behavior of the Advanced Color tool. Using this you can interpolate smooth color gradients between user-defined color breaks. It will be only set when GHX is created for the first time.

Memory and Performance

The Memory and Performance tab contains the following settings:

Memory Cache Size - Controls the amount of RAM memory which is reserved for caching raster data when performing any raster operation. The cache memory is used to keep recently used data in RAM so it is quicker to read and process. The cache size can be increased or decreased depending on the available system resources and processing needs. As a general rule the system will perform better with a larger cache as it will have to do less disk reading and writing when performing a data intensive processing or analysis task. If the system memory is less or equal to 2 GB, then by default the cache size will be set to Normal. That means 50% of the system memory will be used for any operation. If the system memory is greater than 2 GB, you can set the following options in the Memory Cache Size drop-down list:
1. Low = (1024 MB)
2. Normal = Max(50% System Memory, 2 GB)
3. High = Max(50% System Memory, 4 GB)
4. Maximum = Max(50% System Memory, 8 GB)
Automatic Interpolation Cache Size - Select this option if you want MapInfo Pro Advanced to automatically control memory cache size when creating rasters from points using the interpolation method. When disabled, you have to specify the Interpolation Cache Size.
Interpolation Cache Size - Controls the amount of system memory (RAM) which is reserved for caching data when creating a raster from points data using the interpolation method. This is specified in Megabyte. The range is between 1024 MB to 50% of available memory on your computer.
Run Tasks in Sequential Mode - Runs the raster operations in sequential mode. When enabled, the Raster engine applies resources to complete one operation before moving to the next. When one operation is in progress, rest of the operations would be waiting in a queue.

File Paths

The File Paths tab contains the following setting:

Temporary Folder - You can set the temporary folder in your computer to store the selected TAB files and other associated files created due to a raster analysis or processing operation.
Task Log Custom Folder - You can set the folder in your computer to store the Task Log file for the completed raster operations.

Windows

The Windows tab contains the following settings:

Window Display Mode - The Window Mode drop-down list lets you set the map window mode in either Docked or Floating.
Preserve Map Window Scale - The Preserve Map Window Scale check box lets you preserve the map scale of docked map windows when performing an operation on an input raster.
Restrict Decimal Precision - The Restrict Decimals check box lets you preserve or remove decimal values.
Decimal Precision - The Decimal Precision slider control lets you set the precision of decimal values. The range is 0-15. This control enables you to set the number of decimal places of accuracy that will be visible when working with entered or returned values.

Output Settings

The Output Settings tab contains the following settings:

MRR Compression - This drop-down list lets you select the default output compression method when saving an input raster as a continuous MRR. Examples of continuous field rasters are MRR, GRD, ERS, etc. For more information see, Compression Settings. The available compression methods are:
1. None
2. Data Balance
3. Data Space
4. Data Speed
5. ZIP
6. LZMA
7. LZ4
MRR Compression Imagery - This drop-down list lets you select the default output compression method when saving an input raster as an imagery MRR. Examples of imagery field rasters are BIL, BIP, BSQ, JPEG, PNG, BMP, etc. The available compression methods are:
1. None
2. ZIP
3. LZ4
4. LZMA
5. JPEG
6. PNG
Compression Level - This drop-down list lets you select the default compression level when saving an input raster as an imagery MRR. The range is 0-9.
Display Raster on completion of processing - When selected, it enables the display of output raster on a map window after an analysis or processing operation is complete.
Save Log on Completion of Processing - When selected, the log file is automatically saved after an analysis, processing or create raster operation is complete. The log file records the events that occur during the raster operation. You can set the default behavior of where the log file will be saved.
Output File Folder - The log file is created in the same directory where the output file is created and suffixed with .task extension. In case of Volume operation, the log file will not be created if the volume is not calculated.
Custom Folder - You can set the custom folder in File Paths. The log file is created in the directory specified in Task Log Custom Folder option of File Paths.
Note: If the raster operation does not create the output file, the log file will not be created.
Open Raster Preferred View - This drop-down list contains the preferred view modes when a raster is opened. The available modes are:
1. New Mapper
2. Current Mapper
3. Automatic
4. No View
Encoding Type - This drop-down list lets you select the default Encoding Type when saving a raster to MRR format. The Encoding Type options appear in the Output Settings section of the dialog box to enable you to compress the data when saving a raster to MRR format. Encoding Type is enabled only when the raster field type is Continuous and the compression method is lossless such as ZIP, LZMA or LZ4. For more information see, Predictive Encoding.

Raster Formats

The Raster Formats tab contains the following settings:

Native Formats - This table lists all raster formats that will be opened by the native raster handler in MapInfo Pro Advanced.
GDAL Formats - This table lists all raster formats that you can open and perform processing operations, supported by the GDAL driver.
Note: For Native Formats, you can only enable or disable the Display options. All Processing options remain enabled by default and they can not be disabled. For GDAL Formats, you can enable or disable Processing and Display options. To enable any of the Display options for the GDAL formats, you should enable the corresponding Processing option first.

Processing and Analysis

The Processing and Analysis tab contains the following:

Sampling Frequency (Line Stats and Cross Section) - This field enables you to set the number of points (samples) taken along the line of Cross Section or Line Stats tool that is used to create the x-y plot of distance versus grid value in the graph window; the greater the number of samples, the more detail will be displayed in the cross-section plot.
Run Tasks Parallelly in Batch Mode - You can run Convert, Resample and Reproject operations in batch mode. Running an operation in Batch Mode allows you to process multiple input files with the same set of input parameters in a single go. The input raster's properties, for example field type, coordinate system and geometry should be same.
