![]() Gp. Import arcgisscripting, sys, os, shutil, datetime, re ![]() I made a few changes to my code and it works now! I'm unsure what was happening before. Generally, increasing the size of a digital image will cause it to look blurry. Scaling up a raster graphic also decreases the image quality. The further an image is scaled down, the less detail can be maintained. #gp.CopyRaster_management(wholeFile, outFile, "#","0","#","NONE","NONE","#")Īrcpy.CopyRaster_management(wholeFile, outFile, "", "", "", "NONE", "NONE", "") A good image scaling algorithm or 'scaler' will keep most of the image detail when scaling down an image. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps. The word raster comes from the Latin word rastrum (a rake), which is derived from radere (to. In its simplest form, a raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. By analogy, the term is used for raster graphics, the pattern of image storage and transmission used in most computer bitmap image systems. Gp.CalculateStatistics_management(wholeFile, "", "", "") Regular data grids require a referencing object, vector, or matrix that describes the sampling and location of the data points. Gp.AddToolbox("C:/Program Files (x86)/ArcGIS/Desktop10.0/ArcToolbox/Toolboxes/Spatial Analyst Tools.tbx") Raster data, also known as data grids, stores map data as matrices. Gp.AddToolbox("C:/Program Files (x86)/ArcGIS/Desktop10.0/ArcToolbox/Toolboxes/Data Management Tools.tbx") Import arcgisscripting, sys, os, shutil, datetime, re, arcpy JPEG uses lossy compression to decrease the file size. A JPEG, or Joint Photographic Experts Group file, is one of the most common image file formats, and you can use it for photos, graphics or web images. I've specified my extents several times through my code, but I don't understand why this doesn't 'take' in the final product.Īny ideas? Thanks for your thoughts in advance. Here is a list of 15 different types of image file formats you can use: 1. For some reason, after the update of ArcGIS 10 SP1 I am not able to define extents of these images such that the extents remain in the raster images after I convert them. Hello, I'm trying to import and define the extents of raster GeoTIFF images.
