Origin Ver. and Service Release (Select Help-->About Origin): Origin 2025 (64-bit) SR1
Operating System: Win 11
I am having trouble when I export a large graph: No matter what DPI setting I choose, the quality of the exported image (jpg, tiff, ...) looks the same - with low resolution, and blocky text. I know it is possible to get a higher resolution version, because I was somehow able to do it in 2015 with an older version of the same graph.
Am I missing something obvious? |

Chao,
The OpenGL settings did not change anything. However, exporting as an SVG did work, and I was then able to convert that to a pdf file.
Thank you for the suggestion.

Hello Lowell,
Thank you for the information.
3D graphs are a bit different in that they use the OpenGL to render the graphics. This means that it is largely dependent on your graphics card and drivers.
See: https://www.originlab.com/doc/Quick-Help/3D-Graph-Tick-Label-Anti-Aliansing
I also recommend you give the SVG file type a try.
Best,
Chao

Chao,
The graph is 40inches by 20 inches, and I have tried multiple dpi settings (150, 300, 600, ...). When this worked previously, I used 150dpi.
It is a 3D graph, with a matrix plot as well. Anti aliasing is on (in fact, I cannot turn it off). The text and lines all look very clean on the graph in Origin itself - it is only when the graph gets exported that the resolution gets worse. I've upload a screen capture of a small part of the exported image.
I've tried both the Export Graph and the (Advanced) version - getting the same result.
Thank you,

Hello,
How large is your graph and what DPI settings are you using?
Are you using the Export Graph or Export Graphs (Advanced) dialog?
Are you exporting a 2D or 3D graph? Is Anti-Aliasing turned on?
Do you have some examples that show the blocky text issue?
Best,
Chao |
