How to increase image quality to high resolution in touchgfx ?

Hello All,
I am facing the issue for displaying the high resolution images, while running on Touchgfx simulator and STM32H757I-Eval board. I am using the 1000 X 682 image on .png format.

Though I have made Image scaling algorithm to Bilinear Interpolation but the image quality and text in those images do not look refined. The original image and the simulator image has lot of difference in its quality.

Let me know how I can increase and make the display image resolution to get better image quality ?

 

Regards,

Shiv

Hello @ShivDesh ,

 

Perhaps the best solution for you would be to use an image to your correct resolution, simply re-create the image you need to fit your project.

If you need to rescale the image at runtime, it is better to use a higher resolution image and scale it down so you have more information in your image.
