Hi all, I would like to write a collection of RGB rasters located in a folder to a single pdf, with one raster per image. I see that a methodology is outlined here: https://community.esri.com/t5/python-questions/export-multiple-raster-into-single-pdf-using-arcpy/td-p/507608 However, this is for arcmap 10.x. I am wanting to go through a collection of rasters, loading each one individually into a layout, and then print the layout to a pdf, and then remove the raster before adding the next. Is it possible to do this in Arcgis Pro / arcpy? If anyone could point me in the right direction, I would greatly appreciate it. ... View more

Hi all, I am trying to understand the behavior of ExtractMultiValuesToPoints when incorporated into an Arcgis tool. I have used the function in an Arcpy standalone script, and it works just fine. However, after incorporating into a python tool, the stars have to be aligned just right for it to work. Included is a tool that I have created to extract values from a multiband raster into a new shapefile. The issues are (1) I have to rename the bands because the tool generates new names not related to the raster bands, (2) if the shapefile is linked to the tool from a GIS workspace, the names aren't carried over, (3) rasters cannot be linked to from a GIS workspace and (4) ExtractMultiValuesToPoints has no option to preserve the original file (as far as I can tell). These are really just minor annoyances, so am wondering if I am somehow doing it wrong. Thanks for any information.   class Combine_labels_features(object): def __init__(self): """Define the tool (tool name is the name of the class).""" self.label = "07 Combine labels and features" self.description = "This tool combines the labels point shapefile (generated and QAQC'd) with the appropriate features file" self.canRunInBackground = False def getParameterInfo(self): """Define parameter definitions""" labels = arcpy.Parameter( displayName="labels file", name="labels", datatype="GPFeatureLayer", parameterType="Required", direction="Input") labels.filter.list = ["Point"] features = arcpy.Parameter( displayName="features (raster)", name="features", datatype= u'GPRasterLayer', parameterType="Required", direction="Input") outfile = arcpy.Parameter( displayName="outfile", name="outFile", datatype="DEType", parameterType="Required", direction="Output") params = [labels,features,outfile] return params def isLicensed(self): """Set whether tool is licensed to execute.""" return True def updateParameters(self, parameters): """Modify the values and properties of parameters before internal validation is performed.
