oPrn:SayBitMap

[asito]

Hi, I'm having a problem with the instruction:
oPrn:SayBitmap(x,y,cFile,nWidth,nHight,nScale)

The Bitmap I'm trying to print is a 250,70 pixels BMP. It displays it fine in the preview (oPrn:SayBitmap(1,1,cFile)) but in the printer is very small (about .5 x .5 cms.).
I calculate the horizontal and vertical resolution for 80 cols and 60 rows.

I had a routine in FW 1.9 that worked fine but now with FW 2.4 it is not working.
As a matter of fact it works fine with oReport:SayBitmap.

I haven't found any reference on how to use the nHight,nWidth and nScale parameters. Any suggestion ?

Advanced thanks for your attention.

Hi

you can use new Image.prg within FreeImage to modify your Printer.prg.

After several tests I found out that the parameters on the oSayBitmap work this way:

I have an bmp image 250,70 pixels, if I print it with oPrn:SayBitmap(1,1,'Image.bmp') it will be barely visible (about 1 cm).

You should play with these numbers to adjust the size you want. A 500,140 would show a decent logo.

On the oReport:SayBitmap() instruction, it works entirely different.

Hi Asito

Have you tried the output on different printers with the same nWidth
and nHeight ?

I found the output is varying from printer to printer.

Can anybody suggest me what is the common mechanism to get a
constant output on any windows printer with the same program.

Image sizes are in pixel but pixel sizes change from printer to printer. You have to calculate how many pixels are needed to cover a specific paper area:

oPrn:SayBitmap( 0, 0, "IMAGE.BMP", oPrn:nHorzRes() / 4, oPrn:nVertRes() / 8 )
