GXIMG class¶

class GXIMG(handle=0)[source]¶

GXIMG class.

The GXIMG class performs read and write operations on grid file data. When efficient access along both rows and columns is desired the GXPG class is recommended (see GXPG and GXPGU); the GXIMG is first created, then the GXPG is obtained from the GXIMG using get_pg.

Note:

The GXIMG methods use the XGD DATs to access grid files in different formats. The characteristics of a grid can be controlled using decorations on a grid file name. For example:

create_new_file,1,100,100,”mag.grd”); -> creates a new grid file “mag.grd” with all defaults.

create_new_file,1,100,100,”mag.grd(GRD;comp=none)”); -> creates a new grid file “mag.grd” with no compression.

create_new_file,1,100,100,”mag.grd(GRD;comp=size;type=short”); -> creates a new grid file “mag.grd” compressed for size, numbers stored as 2-byte integers..

See DAT_XGD constants.DOC for information about file name decorations available for all GXDAT types.

Different grid types support different features. For example, not all grid types support projection information. Geosoft will always create a *.gi file that is used to store all such information that we require from a grid. If the grid does support this information, both the grid and the *.gi file will contain the information.

__init__(handle=0)[source]¶: Initialize self. See help(type(self)) for accurate signature.

add_fault(xVV, yVV, type)[source]¶

Add a fault trace

Parameters

xVV (GXVV) – X locations GXVV
yVV (GXVV) – Y locations GXVV
type (int) – Fault type IMG_FAULT constants

Returns

index of the added fault

Return type

int

New in version 9.10.

Note: The X and Y values cannot be dummies. Polygons require at least three locations, Polylines require at least two.

classmethod average2(grid_in, grid_out)[source]¶

Reduce the dimensions in a 2D pager by a factor of 2

Parameters

grid_in (str) – Name of source Grid
grid_out (str) – Name of output Grid

New in version 5.0.

License: Geosoft Open License

Note: This method is useful for reducing the dimensions in a 2D pager by a factor of 2. The output pager retains the same origin, but the X and Y spacing is double that of the original. Essentially, the process removes all the even-indexed rows and columns, while leaving the locations of all the remaining data points in the “odd” rows and columns unchanged.

The output values at the output data locations are created by performing an average of the original data point and its valid surrounding data points; what is essentially a 3x3 smoothing filter.

Return type

New in version 5.0.

License: Geosoft Open License

Note: When the GS_DOUBLE data type is chosen the actual on-disk type of the input image will be used instead of GS_DOUBLE if the on-disk values represent color data as opposed to real numbers.

Returns

GXIMG object

Return type

New in version 5.0.

License: Geosoft Open License

Note: When the GS_DOUBLE data type is chosen the actual on-disk type of the input image will be used instead of GS_DOUBLE if the on-disk values represent color data as opposed to real numbers.

create_projected(ipj)[source]¶

Applies a projection to an image.

Parameters: ipj (GXIPJ) – Projection to apply

New in version 5.0.

License: Geosoft Open License

Note: The GXIMG now appears to be in the projected coordinate system space.

create_projected2(ipj, cell_size)[source]¶

Applies a projection to an image, specify cell size.

Parameters

ipj (GXIPJ) – Projection to apply
cell_size (float) – Cell size

New in version 5.0.

License: Geosoft Open License

Note: The GXIMG now appears to be in the projected coordinate system space, with the specified cell size. If the cell size is rDUMMY (GS_R8DM), one is automatically calculated, as with create_projected.

create_projected3(ipj, cell_size, exp_pct)[source]¶

Same as create_projected2, but set expansion of bounds.

Parameters

ipj (GXIPJ) – Projection to apply
cell_size (float) – Cell size
exp_pct (float) – Expansion percent (>=0).

New in version 6.3.1.

License: Geosoft Open License

Note: The GXIMG now appears to be in the projected coordinate system space, with the specified cell size. If the cell size is rDUMMY (GS_R8DM), one is automatically calculated, as with create_projected. The expansion percent expands the bounds of the projected grid in order to allow for the curving of bounding edges. Normally, edges are sampled in order to allow for curving, but this parameter is set to 1.0 (for 1 percent) in the create_projected and create_projected2 wrappers, and will generally create a white/dummy border around the new grid. This new method allows you to specify the expansion, or turn it off (by setting it to 0). If the value is set to rDUMMY, then expansion is left at 1.0, the legacy behaviour.
