How can a image resulting of a “Make text Image”-node have a 2 Pixel width, if i put no text inside?
For some reason they add 2 pixels to the width and the height of the texture in the Make Text Image node. That is how it happens, don’t ask me why it is like that. Probably something weird happens if that is not done.
The 2 extra pixels are to account for the antialiasing on strokes that touch the edge of the glyph bounds — without those pixels, some edge strokes are slightly cut off.
But, good point about it not making sense to output an image when there’s no input text. I filed a bug report.
