I am trying to command-line rendering an PNG file from obj+mtl file instead of using blender.
Currently, I'm using blender to load the obj+mtl file, and then use the render feature of Blender. But, that requires GUI to do so.
I need to render a batch of PNG files with different textures on the same obj on a server.
How should I do that?
Thank you very much!

I want my python script so save the python window as a .JPG, which it does. But when I try and open that .jpg with any application it tells me the file type is unsupported.
When I save my file as a .eps file it opens correctly but when I try and save as any other file type the file will not open.
win.postscript(file="image.jpg", colormode='color')
from PIL import Image as NewImage
img = NewImage.open("image.jpg")
Tkinter canvas object can only be saved as a postscript file, which is actually a postscript printer language text file.
Thus if you call:
win.postscript(file="image.jpg", colormode='color')
It will still write and create a postscript file, that is why it works when you rename the extension [or simply append] with .ps

Here is the situation. I use the Inkscape command to transform png file to svg file.
Like this in cmd:
inkscape image.png --export-plain-svg=image.svg
However, I need to remove the background of the svg file.
The GUI process is (1) open up the file, (2) select all(Alt + A) and (3) selecet "Path" -> Trace BitMap -> click the Remove Background. Finally, save it.
Is there any command which can insert in the terminal or cmd even in python to do this process???
i might have thousands of svg files...
What you're doing with your command is embedding a png image into an SVG image.
What you want to do is to trace a png image to turn it into vector data. I don't think tracing works without GUI currently. What you want is not possible with Inkscape 0.92.4.
You need to either:
use a different software or
write an extension that can run potrace without parameters, or with default parameters or
run potrace directly
do this manually
I have been fooling around with python and Pythonista 2.5 on iOS. I currently am far too inexperienced to create good UIs in scripts and need some help using the designer in Pythonista. I currently wish to add an image asset, yet I am only able to use stock images provided, is there any folder path I can follow to add my images to that list, or is there another simple way of doing it?
Keep in mind I have little experience and thank you for any help!
You can store the images files in any folder. A simple way to copy external images would be to first copy it in clipboard (may be from photos) and then save it as png file by running the following script.
(Custom images are currently not supported in the UI editor, You have to load them via code.
https://forum.omz-software.com/topic/3668/images-in-ui-designer
But you can use the [+] button in the code editor (at the top) to view bundled images/textures. (images in the current directory are also shown.)
https://forum.omz-software.com/topic/3760/itunes-file-sharing )
import clipboard
image = clipboard.get_image()
image.show()
image.save('img1.png')
You can also use dropbox or appex scripts to store images.
I am new to VTK and using python bindings. I am trying to render some objects as images. I am using vtkPNGWriter to save the rendered image. I want to attach the vtkPNGWriter to the interactor so that it saves the rendered images after every time I change the object pose using the interactor. Could someone please help me with this task?
I'm generating some pdf's with Reportlab and Django using a web interface. The pdf's are always going to be a single page. I'd like to generate a png or jpg image of the generated page and return that to the browser for the user to preview before saving the final pdf and delivering it to the end user. Is there anyway to do this?
This answer explains that you can use ghostscript to convert pdf to png. Depending of the requirements of your app (traffic, response time, nb of pdfs ...) it may or may not be a solution for you.
This is just an idea, but may be you can generate the preview image in parallel using PIL ImageDraw and get rid of the pdf-to-png conversion.
I hope it helps
