How do you plot a bitmap?

Intel_C_Intel — Tue, 30 Jul 2002 14:24:25 GMT

I have displayed a bitmap on the screen using the StretchBlt command.
I now want to send the bitmap to an HP plotter using HP RTL commands. Has anyone done this and has an example of how to do it?
I have sent lines to the HP plotter using SP,PU & PD HP-GL commands in the past

Thanks,
David

Mhm, I'm not quite familiar with that plotter stuff, but GDI is supposed to encapsulate HP-GL if appropriate driver is present. The printing routines (GDI) I wrote once did work flawlessly on HP and Epson plotters too.

Take a look at XFTGDI. Does it work on a plotter? (Take care not to specify large paper format - if you forget, send me the paper so I can use it as an ad poster :-))

Thanks,
I looked at your code and documentation - but couldn't see anything about plotting a bitmap.
I want to write to a file using HP commands, then send the file to the plotter.

Yes, my point was that you can treat the plotter as a printer and do a StretchBlt to its DC (XPlaceBitmap and XBitCopy are wrappers around StretchBlt). However, if you really have to write to file using HP-GL, well... you're on your own.

Thanks,
Looks as if I'm on my own, unless anyone else can help.
I wanted to use HPGL commands as that is how I plot my vectors.
I could change all my plotting... but not yet.

You may be able to OPEN the plotter as a file with FILE='network_address', where network_address is in the form serverprinter (assuming this is a Windows network). After that, use WRITEs or PRINTs to send your HPGL commands to the plotter one at a time. CLOSE the "file" once you're done plotting.

I seem to recall doing something similar once, but it's been a while.

If your program uses a graphics language such as HP-GL, look at Fortran_WinprintDirect.f90

Steve,
Thanks for the reply.
But how do I use this to plot a bitmap.
Do you have an example of the call.
The first parameter is a unit - a file - this cannot be the bitmap?

You said that in the past you sent HP-GL commands to the plotter. Well, I told you how you can send HP-GL commands - you write them to a file and then call the routine in Fortran_WinPrintDirect.

If you want to render a bitmap to a page and print that, I don't have ready code for that purpose. If you look at the Win32 SDK documentation on using printers, there is a C sample that prints a bitmap - if you study that and look at Fortran_WinPrint, you should be able to work it out.

Sending the file to the plotter is not a problem.
The problem is creating the HP-GL file from the Bitmap.

Just dropping in to say I have been greatly disappointed with the response you were getting from Intel. I have the same need and I have been unable to get the info I need. I want to write files in HP-RTL to go direct to large format HP DesignJet plotters. I typically have 42 inch by severa feet plots. HP and Intel have been no help.

If you get this reply, let me know.

Ralph,

I'm sorry to hear you are disappointed in Intel's support, but our technical support does not extend to tutorials on programming.

I don't know HP-RTL, but if it is anything like HP-GL, in that it is a series of text commands, the Fortran-WinPrintDirect.f90 example code should do what you want.

The Link Fortran_WinprintDirect.f90is not true. Please post the correct one.

How do you create the bitmap? If you draw it on a device context, then you must use drawing commands.
Why not, for each drawing command, duplicate its equivalent in HP-GL commands, or wahtever,at the same time and copy them to a file?

Or how about trying SPLOT, see here http://www.swplot.com/splot.htm?
(P.S. I have no experience of it, but it came up when I used Google to search fro 'HP RTL'.
