I have a large image where users can add text layers to annotate parts of the image. Is it possible to make the text layers zoom independent?
So say I added a text layer with 12 point font. No matter the zoom level (50%, 100%, 200% etc), I would like to maintain the text at 12-point font on-screen. Is that possible, or do I need to adjust the font size manually to sync with the zoom level?
While I can adjust the font sizes, how about line widths in line and polyline layers? The minimum line width is 1 pixel, so is there a way to still draw 1-pixel lines when the zoom level is > 100%?
Thanks in advance. |

Hi
Zoom independent layer properties is not yet possible, but it is on our to-do list. I will try to get onto this before too long.

Hi Ray
We pushed this feature back because there were some dependencies that it affected. We'll look to implement in 2022.

Seeing as how I only needed to draw resolution independent lines for polylines layers, I took a stab at using the OnDrawBackBuffer event. I set the polyline layer fill and line color to none, and instead drew the lines in the OnDrawBackBuffer event using the layer's points.
At 100% zoom or so, the grip handles match up with the manually drawn lines. Beyond 500% or more, the lines start to diverge from the grip handles at certain points.
The white line is the layer's line (displayed for reference) and the red line is drawn in the OnDrawBackBuffer event.
The divergence increases as the zoom level increases. I've attached the sample project, which basically uses the GetPointEx and XBmp2Scr functions to determine where to draw the lines.
Is there some other function I should be using instead, so that the lines converge nicely at the grip handles?
Thank you in advance.

Hi Ray
Please email me next week after the release of 10.3.0 and I'll have an update that supports ScaledProperties.
