When using the toolbar buttons for some plugins (like OCPN Draw), the visibility of those (and other) toolbar buttons deteriorated (turned black or in other ways distorted). See the enclosed screenshot.

Hi Dave and All
Thanks for this new version


I have the same problem or similar. as above,

I would add that when toggle hide/show the toolbar, some icon are blackened generally at the bottom (MOB) and more, the icons no longer follow there state. I mean they do not change when you click on its.

On macOS 10.15.4 toggling of the icons does work.


- Dashboard: is located "off-canvas". Was the position before moving/resizing the OCPN window.

I found the way to have the scaling in version 5.0.604. Someone should have known this.
Thanks anyway.

Thank you so much for continuing to develop and improve this fantastic software.

I very much like that mbtiles and kap files are not loaded as overlays by default. I prefer to select the overlay option with the blue or magenta button.

However, it seems that when I *do* select a mbtiles overlay, I get what appears to be a big black square instead. If I zoom right in, I can see there is actually a satellite image, but the contrast(?) is so wrong that details are lost. This does not happen with kap files.

Thanks

Yes. I agree with P_Dub... the new default font size is way too big. The soundings are completely overwhelming the the text for other important objects such as the navigation marks. Screen shot attached. Windows 10.

I would like to see the depth font size the same as the nav marks description, they are after all equally important.

Tide stations are huge too.

Seems to be some trouble with your MBTiles overlay files.

Will you post them here for analysis?


Thanks

Regarding depth soundings fonts.
On your screenshot, if "chart object scaling" is "0", then I do agree that these soundings are too large. By comparison, have you changed the default font and/or size for other chart objects?


Thanks

Please explain. Others might benefit from your wisdom....

All set to "0" and in any case disabled.

No font or object size tweaks.

This on a laptop ASUS ZenBook 1960 x 1080 screen with high dpi.

An observation is that by default the screen is scaled to 125% (see screen shot from Windows display settings). If I change this to 100% all of text on the charts is scaled accordingly (to minuscule); except for the soundings. It appears that the size of the settings is being set to some absolute size?

P_Dub...
"Why not have a proper scaling such as:- 1/20000, etc.…, this could help to have a better idea to compare with raster charts, which are still the basic of paper charts required to be carried onboard any vessel. IMO as requested that for many years. Is it that hard to understand!"


Not hard to understand, has been explained many times before.
OpenCPN runs on many platforms, of variable screen size and resolution. The only way to accommodate this, and the only sensible way for ENCs, is to display the chart scale as "actual rendered scale on the screen". That is, use a calibrated scale device (like a caliper), and you will see that the reported scale is correct for your screen and its resolution.

The special numbers like 1:25,000 don't represent anything special on ENCs, by the way.


Further, if we show a scale of say 1:20,000 accurately, you will not find this useful in comparing to a raster chart of 1:20,000, unless your computer monitor is as physically large as the paper chart. This is unlikely, today. You will more likely see a very small clipout of the equivalent paper chart on any reasonable computer monitor. Probably not what you wanted.

OK, here is a case of Windows being, as always, helpful but cryptic.....
You are correct that the soundings font is being set directly by OCPN. Using the OS reported values for screen size and resolution, the soundings (at scale=0) are intended to be 2.5 mm in height.


Will you do two things?



1. Will you post a shot with external Windows scaling set to 100%?
2. Will you find a small ruler or caliper and measure the size of the sounding font on-screen? In an earlier post Hakan pointed to a cool Windows tool that overlays a virtual metric scale on the screen. This could be useful as a cross-check.

Here you go. I physically checked the calibration of the ruler in each case. At 100% the calibration was 140px / cm and at 125% 190px/cm

The scale is shown in the filename of the screen clips.

The soundings are bigger at 100% circa 5mm high and circa 2.5mm at 125%

I acknowledge the missing color in the box on Windows.
This is a bug, and will be fixed.



Meanwhile, do you agree with cagney:
Even though the color is not shown in the box, the color of the track can be changed by clicking on the (empty) box?


Thanks
Dave

Moo...
Thanks.
Sorry, I am not seeing the "100% circa 5mm high".
Maybe 3.5, or so?
In either case, have you checked the tool against an actual, physical ruler?


I'm not trying to be picky here, Or maybe a little bit. But we need to understand what items Windows is scaling, and exactly how their algorithm works.


For instance, on your two pix, is the actual onscreen distance (in mm) from two known geographical points the same?
