Completely new low-level graphic AFL interface allows complete flexibility in creating any kind of user-defined display. The interface mimics closely Windows GDI API, with same names for most functions for easier use for GDI-experienced programmers. The only differences are: All functions use PIXELS as co-ordinates (when used on screen).

Nov 30, 2019 · The recipe for better performance is as follows: If you are using low-level graphics: First you should limit drawing to visible range (GetFirstVisibleBar,GetNextVisibleBar). Second you should NOT be doing coordinate conversion in AFL.

Text color can be set using GfxSetTextColor () function. If a formula needs to update the current position when it calls GfxTextOut, the formula can call the GfxSetTextAlign function with flags set to 1 (TA_UPDATECP Windows flag).
