Scale image and relativ SurveyPoints #2

Scales the Image to the size of the window. Good for Images larger than your screen. Replaces the pixel position for each SurveyPoint with the relativ Position.

@SWAGESC I just noticed this PR, and also see that you've closed it. Was there a technical issue with this? Do you still want it merged? I haven't tried it yet...

SWAGESC commented 4 years ago

it is my first Pull Request ever. I thought i found an error. I will reopen it.

P.S. Love that project... hope there will be more Progress. An Open Source Heatmap is a thing that every Administrator needs.

SWAGESC commented 4 years ago

I close the pull request. iwlist is crap for creating a heatmap. I will try another solution for the collection problem

jantman commented 4 years ago

@SWAGESC Ok. For what it's worth, I usually refer to the actual iperf heatmaps, not the ones based on iwlist quality. This application should generate 6 (six) heat maps:

jitter_TITLE.png - Heatmap based on UDP jitter measurement in milliseconds.
quality_TITLE.png - Heatmap based on iwconfig's "quality" metric.
rssi_TITLE.png - Heatmap based on iwconfig's signal strength (rssi) metric.
tcp_download_Mbps_TITLE.png - Heatmap of iperf3 transfer rate, TCP, downloading from server to client.
tcp_upload_Mbps_TITLE.png - Heatmap of iperf3 transfer rate, TCP, uploading from client to server.
udp_Mbps_TITLE.png - Heatmap of iperf3 transfer rate, UDP, uploading from client to server.

I agree that the iwconfig quality and rssi (signal strength) aren't reliable. For my own purposes, I relied on the actual, real-world iperf3 transfer rate maps.
