• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

How to find out how many records are in subsection of bgl file (aerial photo)? All I know is

TRQ1 Record
x04 4bytes - DWORD - Size of this record = 0x28

Size of the subsection’s data is 68 bytes. I can read first record (the header), it's size is 40 bytes. But how to find out if there are next records to read (how to find their offset)? Also I am interested what are the remaining 28 bytes. There is another size at offset 0x10 which is 0.
 
I will admit to being curious about your efforts, seeing as we have access through other tools to most all the default data.

But now I am curious about why you want to access photo based scenery, which will be 99% other people's work?

As someone who has produced a commercial product based upon aerial imagery, I have a very uneasy feeling about your efforts. However futile I believe they will be.
 
Why would somebody steal somebody's work from bgl if he has the bgl? Sounds absurd to me. Think about possibility to encode my own bgl files directly from my program without using resample.
 
You can access resample from your own program, so you do not need to encode directly.

If I could encode directly I should gain better performance and should do many things faster and simpler without need of having bmp files and inf files on my disk. The informations would stay in memory and then be encoded directly. As far as i know resample does not use multithreading, but my app should use multithreading. I would simplify many things.

And please stop philosophise. If you have nothing to say to programming in this thread so you are off-topic. I asked directly and I expect direct answer.
