Color background in textnode??

[Blanca Calderon]

Hi,

I have a big problem with text node. If I create a diagram with a textnode inside and transform .edd into .jpg the next node inside has background, has pixeles.

It is so important in my tool not having this.

Any help would be appreciated.

I don't know if i have to modify this or it's when I create the textnode that I have to put color or similar.

I've used your example to reproduce the problem. As you could see when the background color of the textnode is transparent pixels appear around the text.

When I export my image as .bmp this doesn't happen but the text always have color. I need to export a jpg always in black & white, never with color or grey scale. This .jpg image is for a display in a PLC and never uses color.

If I try to convert my image .bmp into .jpg these pixeles appear again.

Hi Blanca,
  

Please find the attached image and please confirm us whether you are mentioning the grey colored pixels highlighted inside the red box as an issue? If yes, this is not the diagram control issue. The jpeg format images are not rendered based on vector. So only the image is losing the quality while zooming. The Vector based images can be resized without to lose quality like Bmp/Png format images.
