![]() ![]() Process Color: Process-color images are comprised of cyan, magenta, yellow and black (CMYK). These separations are done in vector-based graphic programs such as CorelDRAW and Adobe Illustrator. Spot-color separations and prints generally are used for logos, school designs, clip art, hard-edged graphics, cartoons or other images that have a dark outline. ![]() Spot-color images generally have specific solid colors, but also can have small halftone dots for shading. Spot Color: This is the bread and butter of the industry. If the image has gradations, shading or photorealistic elements, those parts of the color separation need to be converted to halftone dots that can be burned onto a screenįollowing are details on types of separations common in the decorated apparel industry. library(raster)į <- system.file("external/d", package="raster") Deal with the names after that, if necessary. In your loop you should probably use double brackets ]īut you would use either stack (if the rasters can be stacked - they need to have the same extent and resolution), or else lapply. I don't get those error messages, if you can help me, or you had the same or a similar problem, i'm taking any hint ! rasterObjectFromFile(x, band = band, objecttype = "RasterLayer", :Ĭannot create a RasterLayer object from this file. Number of items to replace is not a multiple of replacement lengthĢ: In vec_of_raster <- (month <- raster(files_vec)) :Ĥ: In vec_of_raster <- (month <- raster(files_vec)) :Ħ: In vec_of_raster <- (month <- raster(files_vec)) :Ĩ: In vec_of_raster <- (month <- raster(files_vec)) :ġ0: In vec_of_raster <- (month <- raster(files_vec)) :Įrror in. Here are the errors (and warnings) that i get : Error in. I'm afraid i want to use two objects (raster and vector) that are either to close to work that way, or can't be associate. Raster_vec(vec_of_raster,files_vec,month,"1995") Vec_of_raster<-(month<-raster(files_vec)) Raster_vec<-function(vec_of_raster,files_vec,month,year_str) Vec_of_raster<-c("raster",length(files_vec)) Setwd(dir = "E:/perso/NEON-DS-Field-Site-Spatial-Data/SJER")įiles_vec=list.files(path = "E:/perso/NEON-DS-Field-Site-Spatial-Data/SJER",full.names=FALSE, recursive=FALSE) I did that for now (here i just tried for 5. I wanted to automate the creation of my raster by month. I'm using a function, and a loop inside this function to create my raster. I did it by hand, but it's really long and i am trying to optimize a bit this code. I'm working on data (24 month, jan,jan2,etc, and for different years), and, for each month (jan,jan2,feb,feb2,etc) i want to create a raster. I am trying to create a vector of raster in R, let me explain. ![]()
