In a raster layer's Style Properties, I can choose pseudocolor render type, and choose a color ramp and classify the raster.      However, when I click the 'Apply' button, or click 'OK', the visualization of the raster never changes.  I was able to output a 'colorized' version of the same raster using GRASS plugin.  I also reinstalled QGIS 2.8, and was able to adjust and see a raster stylings using the steps I outlined above.  So, can anyone confirm this as an issue, or confirm that there's a mistake somewhere in my process?  I should note that I'm on a Mac, 10.10.4, and I'm using the QGIS provided by , 2.10.1-1 .  Update 1: Here's a screenshot of the rest of my settings.      I have Grayscale set to off in the Style setting.  Also, I don't believe grayscale/color-blind Preview is available on the Mac version of QGIS.  They're does't appear to be the option where it , in the Menu Bar under View / Preview / Photocopy (grayscale) etc.  Either way-- I added a shapefile to show color.  Update 2: I've experimented with setting color interpolation to discrete, linear, and exact, but still am not able stylize using Singleband pseudocolor.  I've also confirmed that the 'Render' box on the the main map view is checked.  Also, I am able to adjust Color Rendering settings, like Hue, Blending Mode, etc., and see the results when clicking 'Apply' or 'OK'.  Update 3: As other Mac users are confirming this, I think it may be a bug. I've created a bug report at the official .

i've installed mac version from kyngchaos including all required packages ... ... and just noticed the following:  while windows version behaves like expected when trying to render an ordinary tif via "singleband pseudocolor" (see the image)   the same procedure on the current mac-release returns:   interesting detail: pressing "apply" in mac version doesnt change anything and if you press "OK" and re-open layer properties the "render type"-setting has  swiched back to "singleband grey".  even more interesting: "singleband grey" is faulty too: none of the options "color gradient", "min", "max", "contrast enhancement" does affect the way the tif is displayed,  neither do the "load min/max values" settings !  anyone any ideas?

\documentclass{article} \usepackage{listings} \usepackage{color} \begin{document} \definecolor{light-gray}{gray}{0.95} \lstset{basicstyle=\ttfamily\footnotesize,     backgroundcolor=\color{light-gray}, xleftmargin=0.7cm,     frame=tlbr, framesep=0.2cm, framerule=0pt,   } \begin{lstlisting}[mathescape] k = $\lfloor (10\log n \cdot \log\log n)^{1/3} \rfloor$; k = $\lfloor (4\log n \cdot \log n)^{1/3} \rfloor$; \end{lstlisting} \end{document}   produces    An answer to a similar question said that "this line is just an artifact of the viewer". But this line appears in two viewers and various zoom steps. On top of that, one can clearly see that the 1/3 overlaps with the white line. So I do not accept it as a mere artifact anymore.  How could this problem be approached? Is it possible to somehow put another grey layer underneath the lstlisting environment which would "eat up" any white lines?  edit: Is there a solution that would not involve editing every line of the code?

I have an image that I downloaded online:   As you can see it's not just monotone. I would like to change all shades of the red to shades of a different color (Imagine the red liquid was purple instead of red)  Is this possible in Sketch?   Sorry I'm a programmer, so this is kinda outta my realm of expertise. I'm using a Mac.

I am a beginner using QGIS (1.8.0 Lisboa) on a Mac (OS X 10.6.8 Snow Leopard). I work on a file with two layers in the following sequence (top to bottom):    a vector polygon layer with a few outlines of various buildings in France and Italy (CRS: EPSG:4326 - WGS 84 - "on the fly" re projection is activated ) a Google satellite layer uploaded via open layer plugin.   Sometimes when changing the scale (scrolling in and out) the Google layer updates a little wrong in size or position compared to the polygon layer. But as soon as I "pan" the map everything reconstructs right. Now the problem I have concerns the print composer.  The result of any kind of export - pdf, or image or svg - of my map (vector layer + Google layer in the background) differs from what is shown in the preview of the print composer: the vector layer and the Google layer positions are mismatching and in a different scale. I can send some pictures showing screenshots of the print composer preview and the final results if required.  I tried almost everything:    new files with different CRS settings "cache" update preview "render" update preview different paper sizes,  different scales,   The problem appears only using an open layer map (Google, OpenStreetMap...). If I try the same using two vector layer (shapefile) - one with the buildings, another one with the city in background - everything works out great.  ...exasperating! Since it is a real important research project I would be very grateful for some help and tips.

I looked everywhere from tutorials to documents and either they only talk about texturing or they are doing the tutorial in 'blender render' when I need it in 'cycles render'.   I have a cube that is toon shaded red. And as you can see it is unwrapped to show the map.    Now I would like to add the color that's on the cube onto the map.   As you can see at the bottom of the image that I created a new image called 'untitled'. Now the next step of baking the colors onto the map is where I become lost. Regardless of which 'Bake Type' that I used, I keep getting error messages like: No valid selected objects.  Everything looks selected to me. No, I am not new to Blender but I am new to color baking. Thank you for any help provided; I used a simple cube first before using other models I already created.

Somehow my viewport preview shows darker result than what comes out in render (check out in corner of the pic)  World strength is at zero and ambient occlusion is also disabled.  Floor is using bump and roughness from picture. Wall has adaptive subdivision surface  modifier.  All lit using planes with emission shaders.  I wanted to play around with render layers and maybe I screw some setting there, hope this helps.

I want to give multiple colors to different features within a shapefile based on attribute values , is this possible in QGIS ?  If yes what is the procedure ?  Is there a way to provide color by means of hexadecimal codes ?

I don't know why but now, when i go in material preview or rendered (in solid mode it works fine), my object is entirely gray, or invisible idk, because it has the same color of the background. I've been working for days on this project without having this issue, it suddenly showed up. I tried opening other old projects and suddenly they all do the same so i guess it is some blender program setting that applies for all the projects, but idk how it happened cuz i didn't change anything :/, anyone got any tips?

I want to create and elevation hillshade but I found the script for QGIS 2.18. What should I use instead of processing.runandload? Here is my script on QGIS 2.99 python console:  import processing rasterLyr = QgsRasterLayer("C:/Users/Mustafa Uçar/Desktop/Tutorial/qgis_data/dem/dem.asc", "hillshade") rasterLyr.isValid() processing.runandload("gdalogr:hillshade", rasterLyr, 1, False, False,1.0, 1.0, 315.0, 45.0, "C:/Users/Mustafa Uçar/Desktop/Tutorial/qgis_data/dem/hillshade.tif") #to verify the output image processing.runandload()

I'm following  and I've set my compositor up in the exact same way as he did, except my background is like a slightly light grey and I don't know why.  In his video's he's getting a bright white as his background and I can't see where I'm going wrong.  Here's the render:   Here's the compositor window:    file.  Please help! I really want to know why it's not happening.

I'm looking for a way to insert continuous colour legend for a raster layer.  I managed to create discrete symbols with values along the bar, but I would like to have a continuous bar with some values on the bar, similar to the old plugin "One-Band Raster", that it doesn't work with the QGIS version higher than 1.7  I tried to set in properties->style, where I selected the  Render Type "Singleband pseudocolor" and see the "generate new color ramp" box.  I tried both "Continuous" or "Equal interval". However, in the Composer the legend always is displayed with discrete symbols.  Is there any way that can make QGIS Composer to display a nice continuous band for a raster layer?

I am trying to generate a map with terrain and elevation in QGIS and as a beginner I have followed tutorials on how to generate contours and hill shades succesfully. However, I don't know what are the next steps in order for me to  apply style/colors on based on the elevation. As for my project I am using Global Elevation GeoTIFF from . I am not sure though if this is the right base map/file that I should use to produce what I want, or if this produces accurate elevation data. The map I need to achieve is a terrain + elevation map just like what  uses. Also, if I am able to do this, will there be a way to stitch or collage multiple layers from different sections of a map since processing the entire map takes forever, whilst for a certain country only takes a minute.

In ArcMap 10.1, we can render a raster in a colour ramp (stretched) symbology to draw a raster layer based on each pixel value. However, the legend for the layer by default starts from the max value (top, red) down to the min value (bottom, green).  How can I draw it like form min (top, green) to max (bottom, red) instead?  Tried Invert checkbox but it didn't help as it was the colour that was inverted.

I know that it is possible to color a vector map by attribute. I separated a map into 4 colors based on an attribute and now I want to generate a new map for each color. Is there a way to do this in QGIS?

I was on the latest version before this, 2.92. Everything was fine. I just updated, I clicked to import settings from 2.92 at the first run popup window, all ok. Then I loaded one of my scenes, everything ok. But now, if I try to render, the viewport remains grey, and once I try to revert the viewport to EEVE render, the program simply enters an infinite loop and freezes. The grey space in the middle of the image is the object &quot;rendered&quot; in &quot;Cycles&quot;.  And this below is what happens after I click another render method: menu stuck and mouse pointer rolling.  The same happens if I switch to another panel with a different render method. Update: this only happens when using GPU computer. If it's on CPU, it works. I have just tried with a brand new scene with the cube, where Cycles is set on CPU, and it worked. Once I tried to switch to GPU, again it rendered grey. Then when I reverted again to CPU, the program froze.

I have a series of continuous rasters representing the same phenomenon over time, so I need to use the same symbology across them all.  So I set the stretched symbology of the first raster, with a color ramp from the min/max values:    Now in the second raster, I import the symbology from the first raster. Unfortunately, although the labels match, the actual min/max values are not the same as the first layer:    So the red in the second raster corresponds to a value of 0.47, rather than 0.66.  How can I ensure that both rasters are using a consistent symbology?

I'm using ArcGIS 10.1 for Desktop.  I am trying to export a pretty simple map to PDF and finding the results are not what I expect. I have inserted two graphics on top in Layout. One is just a rectangle that has a custom user style applied. The style uses a Picture Fill derived from a PNG file that has transparency set to 80% opacity in the original file.  The other graphic is a rectangle text box that has a similar Picture Fill Style applied, this one using a 20% grey fill and 80% opacity in the original PNG file. On screen, the boxes look fine. That is, I can see other layer information underneath that looks greyed out with a partially transparent box overlaying.  When I export to PDF, the boxes show up as empty of any fill at all. The sample text in the text box shows up, but not the transparency fill.  Resolution is set to 300 DPI, Resampling is set to best. Colour space is set to CMYK. There is no compression. Bitmap fills are set to vectorize. I have tried varying every setting that can be changed in Export to PDF and find that nothing really changes with regard to this transparency issue.  Any ideas? I have scanned other forum posts and see that it is an issue from several versions back. Has it ever been solved?
