text is not drawn at correct position under certain flag combination

[clearpicks]

I just found sometimes the text is not drawn by drawText() at the correct position. For example, in my testing EFS, if I use Text.RELATIVETOBOTTOM | Text.BOTTOM, the text is drawn at a position higher than it should be.

As I understand it the vertical location of the text appears to be correct. If you use Text.BOTTOM you are aligning the bottom of the text to its location which is set by the height of the font.
Here is a modified copy of your script where you can see the effects of using the TOP, VCENTER and BOTTOM flags. Keep in mind that if you do not enter a vertical alignement flag it will position it as if you had used the Text.TOP flag

var isDone = false;

function preMain(){
    setPriceStudy(true);
}

function main(){
    if ( getBarState() == BARSTATE_NEWBAR && getCurrentBarIndex() == 0 ) {
        if ( isDone == false ) {
            isDone = true;
            drawTextRelative(-1, 0, "Text.VCENTER", Color.white, Color.red, Text.RELATIVETOBOTTOM | Text.BOLD |
                            Text.ONTOP | Text.VCENTER | Text.CENTER, "Arail", 16, "1");
            drawTextRelative(-20, 0, "Text.TOP", Color.white, Color.red, Text.RELATIVETOBOTTOM | Text.BOLD |
                            Text.ONTOP | Text.TOP | Text.CENTER, "Arail", 16, "2");
            drawTextRelative(-30, 0, "Text.BOTTOM", Color.white, Color.red, Text.RELATIVETOBOTTOM | Text.BOLD |
                            Text.ONTOP | Text.BOTTOM | Text.CENTER, "Arail", 16, "3");
        }
        else {
        }
    }
}

Thank you, Alex. I thought the base line was the one specified by y. Actually it seems it should be y+font height.

You are welcome.
It needs to be related to the font height else if you used the Text.TOP flag the text would not be visible or if you used the bar locations (ie AboveBarX, BelowBarX) the text would end up in the incorrect location(s)
