Does Img4j place the text as per the resolution?

Question

I come across this Does Im4Java support adding text to images while specifying font, font-size, and color?

Does im4j places the text as per the resolution of the image? Ex: 16 pts of a font is smaller in high resolution where as it is big in low resolution. If i want to set the size of the font according to the resolution, will Img4 is able to do it. ex:16 pt given should be converted as per the resolution. also font height would differ from font to font.

Thanks

In im4java documentation for pointsize (which specify the font size) they point you to (see the documentation of GraphicsMagick for details), which states:

The pixel units may be converted to points (the standard resolution-independent measure used by the typesetting industry) via the following equation:

size_points = (size_pixels * 72)/resolution

where resolution is in dots-per-inch (DPI). This means that at the default image resolution, there is one pixel per point.
