no horizontal slider after startup #173

Closed geo207 closed 3 years ago

Hello,

I downloaded inspectrum a few days ago, but there is no horizontal zoom slider on the signal area (see first screenshot). I tried resizing and adjusting the window as suggested in issue #170, but it had no effect. Also, when I right click and then click on one of the four options, a new area opens at the bottom of the window, and if I do that again then another new area opens at the bottom; this time the second area is a bright green, but with other signal files it is a different color (see second screenshot). I don't think these new areas are supposed to appear based on what I've read about inspectrum online. I am using a Raspberry Pi 4 (8 GB) and the version of inspectrum is 0.2-1. In the terminal window, when I start inspectrum there are always 6 lines that read, "libpng warning: iCCP: known incorrect sRGB profile" I don't know if this is connected to the horizontal zoom slider missing. Can anyone tell me why I am not getting the slider and what the remedy might be? I don't understand the coding solution in #170 and I'm not sure it pertains to my problem in any case. I'm very disappointed as I have signal files ready to roll! Thanks and here are two screenshots:

twelve hours later....I think I figured it out now. Still working out how to count symbols, but I think I found the cursor and the zoom.

Still working out how to count symbols

You can drag the cursors so that a transition in the signal always lands on a dotted line, and that will setup the symbol rate roughly. Then you can increase the symbol count and the cursors will expand out to cover more of the signal & count out the symbols (you may need to continue tweaking the rate as you go)
