Definition

Checks whether the specified extents are valid for the given <Image> instance.

Returns

SE_TRUE	if all parameters are valid.
SE_FALSE	if fields_ptr is NULL fields_ptr->level_count is zero fields_ptr->mip_extents_array is NULL mip_level is greater than or equal to fields_ptr->level_count start_texel >= fields_ptr-> mip_extents_array [mip_level], or or start_texel > stop_texel

Parameters Notes

¹ fields for the <Image> instance for which the extents are being checked.

² the starting texel index of the <Image> instance data to be retrieved; must be less than or equal to stop_texel, and must be valid for the specified MIP level of image.

³ the stopping texel index of the <Image> instance data to be retrieved; must be greater than or equal to start_texel, and must be valid for the specified MIP level of image.

⁴ the mip_level being requested for the given <Image>.
