Golang GDALReadBlock Examples

Example #1

File: gdal.go Project: kikht/gdal

// Read a block of image data efficiently
func (rasterBand RasterBand) ReadBlock(xOff, yOff int, dataPtr unsafe.Pointer) error {
	err := C.GDALReadBlock(rasterBand.cval, C.int(xOff), C.int(yOff), dataPtr)
	if err != 0 {
		return error(err)
	}

	return nil
}

Example #2

File: gdal.go Project: colek42/gdal

	return C.GDALReadBlock(rasterBand.cval, C.int(xOff), C.int(yOff), dataPtr).Err()
