I've tried to use both Map0.Projection = tkMapProjection.PROJECTION_GOOGLE_MERCATOR Map0.PixelToDegrees x, y, Xx, Yy thatMap0.Projection = tkMapProjection.PROJECTION_WGS84 Map0.PixelToDegrees x, y, Xx,...

Hello all, I'm working on an application that creates a bunch of gis output and it would be quite helpful to enable tif compression to reduce file sizes. From the API documentation it looks like there...

Hi Colin, exactly which methods do you use to produce output? We have TiffCompression global setting indeed. But perhaps it's not used everywhere throughout the code. Regards, Sergei

Basically I'm doing something like this... Dim outputGrid As New MapWinGIS.Grid Dim outputFile as String = "c:\temp\test.tif" outputGrid.PutFloatWindow(0, 5000, 0, 500, outputpixels(0))...

Strange indeed, this method is working for me. You can also try to do the conversion in 2 steps: PixelToProj and then ProjToDegrees. Another option is to convert Google Mercator coordinates you are...

Using gdal in python I would specify the following arguments in the driver.Create function call: create_args = ['COMPRESS=LZW', 'PREDICTOR=2', 'TILED=Yes', 'BLOCKXSIZE=128', 'BLOCKYSIZE=128'] I'm not...

oops, PutFloatWindow would come after outputGrid.CreateNew!

The only thing I want to get the coordinates are indicated by the red arrows in the picture attached. If they are visible on the map, must be able to read...

No, the setting wasn't used. I've committed a quick fix. We are preparing v4.9.3.5 now, so it's likely that this fix will be released within a few days. It would be good to allow to pass other creation...

Internally MapWinGIS uses an instance of GeoProjection class with initialized transformation from map coordinate system (GoogleMercator in your case) to the WGS84 coordinate system to display the...

New Post: GridColorScheme not working on int data types
I've recently upgraded from 4.8.3 to 4.9.0. The code that I had previously to display a grid using a GridColorScheme has stopped working on integer (unsigned 8 bit) but if I convert the tif to a float...

If you can provide me a sample file, I can check how the current 4.9.3.4 version is handling it and try to resolve possible problems. Regards, Sergei

Hello Sergei, I've been trying to figure out what exactly is causing some layers to disregard the colorscheme and haven't come up with anything definitive. I was able to get a different byte type...

I'll second the request for a 64 bit version. I've recently upgraded from the 4.8 version and have been missing a 64 bit version. I tried to follow the instructions for building it from source and it...

FYI, I reverted back to 4.8.6 to test this issue and these same layers display fine on that version of MapWinGIS

I tested your files with the 4.9.3.4 version. I observe the same behavior. The problem is with the selection of the rendering routine. If the following clause is true:if (_dataType == GDT_Byte...

P.S. Most likely I'll restore the old behavior for this type of files (GDT_BYTE single band), as it wasn't done on purpose (just difficult to test every type of file). If color scheme is present it's...

That's great! Thanks for looking into it. I was mistaken in the version I was using it was actually 4.9.2 which is the latest with 64 bit binaries available. For the time being I think I'll stick with...
