Hans! When I pointed out the dimension in pixels I meant the resolution of the monitor, not the dimension of the files. For example, a file with a resolution of 1800x900 was generated on the 1920x1080 monitor, and the other two files on the monitor 1366x768. In this case, the dimension of the file created using bmp2bmp () is selected so that it is well displayed in the window on the monitor 1366x768 and the taskbar is visible.
Jimmy! Viewers give a good result, but they have their own interface, and I need to do it in my interface and display it in my system.

have you try Tip from Diego Kerejeta to use undocumented nCompress = 4
Code: Select all
oBMP:Draw( oPS, { 0, 0, aIcoSize[1], aIcoSize[2] },,, 4 )

I understood what it had to be. And how to change the transparent and opaque options of the bmp2bmp() function with this in mind?
oHuge:Draw( oPS, { 0, 0, aXbpSize[1], aXbpSize[2] },,,4,GRA_BLT_BBO_IGNORE )

NO, that are to much Parameter
Code: Select all
oBMP:Draw( oPS, { 0, 0, aIcoSize[1], aIcoSize[2] },,, 4 )
so instead of GRA_BLT_BBO_IGNORE (2) use
4

4-is it a quality parameter? And what value corresponds to the maximum quality?

please read about
Code: Select all
:draw( [<oTargetPS>] , ;
<aTargetRect> , ;
[<aSourceRect>], ;
[<nRasterOP>] , ;
[<nCompress>] , ; // this Parameter
[<nState>] ) --> lSuccess
in German Help File
Der Parameter <nCompress> hat nur dann eine Bedeutung, wenn der Bereich <aTargetRect> kleiner als <aSourceRect> ist
Параметр <nCompress> имеет смысл только в том случае, если область <aTargetRect> меньше <aSourceRect>
Diegos Tip seems to work fine to use nCompress = 4 when Shrink Size even when Help File say it is not allowed
have fun

Hello,
for complicated conversions I use the commandline of imagemagick with runshell(), is very powerful.

Rudolf!
This is extremely interesting. I've seen information about it. But he stopped digging in this direction when he earned bmp2bmp(). But as I understand it you need to have
cygwin with the right packages. Or is Windows enough?
