I am currently trying to export a map in Qgis to an image format (JPEG or PNG) using the Print Composer. I have three layers on the map and two of them are filled with a texture (lines for South America and dots for Africa and Asia). When looking inside the Qgis fillings seem just fine. However, when I export the map to image format and open it both lines and dots somewhat mingle and the fillings become blurred. Only when I zoom in enough the lines and dots become distinct again. I did some internet research, but I could not find anything useful. Is there a way to export the map to image format and yet keep the fillings similar to what is displayed inside the Qgis?
Thank you.
I am rendering 3d furniture models in Autodesk Maya for an AR app. For showing a shadow of 3d model in scene file I need export of transparent PNG file from Autodesk Maya which I can use as diffuse image for shadow plain. I have attached example of the kind of file needed but I don't know how to generate the same in Autodesk Maya. Please help.Shadow file generated for chair model.
If you want to generate in Maya a UV texture containing shadows for ARKit / SceneKit models follow these steps (I should say that it's not easy if you're a beginner in Maya):
Create objects with appropriate shaders
Create UV map for your models in UV Editor
Activate Maya Software Renderer
Create lights with Raytraced Shadows
Don't forget turn Raytracing on in Render Options
Duplicate all 3D objects and lights
Select an object with cast shadows and a corresponding light
Go to Rendering module and choose Lighting/Shading - Transfer Maps... menu.
Setup all the properties for Shaded Output Map and its appropriate location and then press Bake.
Also you can output four additional passes in Maya Software Renderer:
Normal Map
Displace Map
Diffuse Map
Alpha Map
If you want just shadows, without diffuse texture, use white coloured Lambertt Shader in Maya.
I exported a bunch of png files from R. The pictures are of a dataset that is 'spinning' against a white background. I then use GIMP to stitch them together and export an animated gif. Unfortunately, the gif has a yellowish color instead of a white background like the original files. This yellowish color was not there when I used to do this in imageMagick and isn't even there when I preview the files in GIMP. It only appears after I do the export as a gif. Does anybody know what is going on and how I can correct this?
GIF files are limited to 255 colors. If you don't downsacle colros prior to exporting them, GIMP will do that automatically at the export step itself. It is at this point that your yellowish background is being created.
The workaround is quite simple: convert your image to the indexed color model before exporting the GIF file (image->mode->indexed) ( perceive you could even force a custom crafted palette at this step). If after this conversion the backgroound is already yellowish, you can manually redefine it on the Color Map dialog (search for it on the Windows->Dockable menu) - pick the background color, and change it for white.
When exporting the Indexed image to an animated GIF there is no color conversion step, and the colors of the GIF are saved as they are seen on the screen
The issue here is GIMP is trying to do its best to convert your image down to 255 colors, and that is where it is failing. What I recommend for people on OSX is to get this program called ImageAlpha (it is free) https://pngmini.com/. It does a very good job and compressing png images without much loss. If anybody has a recommendation for a Windows app that would do this, please post it here for reference.
When I export my blender scene as .fbx file and try to open it in Autodesk's Fbx Review afterwards, all material colors seems lost or changed:
Is there a way to maintain the colors?
It is very common for FBX Reviewer, and I think that's because FBX Reviewer uses another strange shader which makes everything brighter. That's just FBX Reviewer's problem and the program has just a few options to change. When you import your FBX file to another program such as Unity or MAX, the color's gonna be okay.
Can anyone tell me if I can export DXCharts to .xls, .pdf or any kind of vector format?
I am using DXChart from the 2011 v2 release for WPF.
I didn't find anything about this on the web. My fear is that I can't.
Thanks
You can use DXCharts along with XtreReports and a report can be exported to PDF.
Note: I do not know if the resulting chart is then a vector or a bitmap
I also added this question on the DevExpress site: http://www.devexpress.com/Support/Center/p/Q394532.aspx
Finally i got to this conclusions:
The DevExpress charts can be exported to JPG by converting the visual content of the chart to a bitmap and saving it as an image file. They can also be exported to PDF, XLS directly using several techniques which are somewhat poorly documented, but with actual results. The list of techniques is shown below:
- Integrating the DXChart in a DXGrid and exporting the grid (to PDF, HTML, MHT, RTF, XLS, XLSX, CVS, TXT, XPS, BMP, EMF, WMF GIF, JPEG, PNG, TIFF) as shown here http://www.devexpress.com/Products/NET/Controls/WPF/Printing/info.xml. However, the chart will be exported as an image and integrated into the appropriate format file.
- No vector format is available, per se, however the image format files allow for a great dpi resolution, which enables a good resize and zooming behaviour.
public void exportChartToPDF()
{
PrintSizeMode sizeMode = PrintSizeMode.Stretch;
chart3D.ExportToPdf("Output.pdf", sizeMode);
Process.Start("Output.pdf");
}
