Printing an image.

[HunterEC]

Guys:

How can I print an image in 8.5" x 11" size (letter) ?

Code: Select all  Expand view

     oImg1:Print( , , , 06 )
 

I know that the

Code: Select all  Expand view

oImg1:Print( , , , n )

method prints the image and sizes it according to n. This requires a trial and error process. Can it be done in just one try ?


Thank you very much !

[nageswaragunupudi]

Please try

Code: Select all  Expand view

function PrnImage

   local oPrn
   local cImage   := "c:\fwh\bitmaps\olga1.jpg"

   PRINT oPrn PREVIEW
   PAGE

   @ 1, 1 PRINT TO oPrn IMAGE cImage SIZE 7,9 INCHES NOTRANSPARENT STRETCH

   ENDPAGE
   ENDPRINT

return nil

Thank you very much for your response, however I'm getting the following compilation error:

Code: Select all  Expand view

Error E0030  Syntax error "syntax error at '@'"

Offending line:

Code: Select all  Expand view

@ 1, 1 PRINT TO oPrn IMAGE cImage SIZE 7,9 INCHES NOTRANSPARENT STRETCH

I'm using FW 16.03, any ideas ?


Thank you very much !

[nageswaragunupudi]

FWH 16.03: Please use the method:

PrintImage( nRow, nCol, cImage, nWidth, nHeight, lStretch, nAlpha, lTransp, lGray ) // All units in pixels

Ex:
oPrn:PrintImage( 100,100, "c:\fwh\bitmaps\olga1.jpg", 5000,7000 )

Rao:

Thank you for your help. How can I find out the pixel size of the full image and how many pixels does an 8.5" x 11" page has ?
Thank you very much my friend.

Gustavo,

The Image is adjusted to a given page-area.
Using small images there is a zoom-factor

look at Your post :

See CLASS TPrinter METHOD Inch2Pix( nRow, nCol )

Code: Select all  Expand view

METHOD Inch2Pix( nRow, nCol ) CLASS TPrinter

   nRow = Max( 0, ( nRow * ::nVertRes() / (::nVertSize() / 25.4 ))-::nYoffset )
   nCol = Max( 0, ( nCol * ::nHorzRes() / (::nHorzSize() / 25.4 ))-::nXoffset )

return { nRow, nCol }

Antonio,

I created a easy to use File-label-section, my customer asked for.
Once the values are defined, only different text is needed.

the paper orientation is landscape
7 labels can be printed
The text-rows, the distance from left to the 1. label and the label-width is defined
The calculation to center the text works fine but the calculation ( pixel ) to center the images doesn*t work for any reason
and I had to use fixed tested values.

nRow = Max( 0, ( nRow * ::nVertRes() / (::nVertSize() / 25.4 ))-::nYoffset )
nCol = Max( 0, ( nCol * ::nHorzRes() / (::nHorzSize() / 25.4 ))-::nXoffset )

I will check :

// SizeInch2Pix is for converting width and height
METHOD SizeInch2Pix( nHeight, nWidth ) CLASS TPrinter
DEFAULT nWidth := 0, nHeight := 0
if nHeight <> 0
nHeight := Max( 0, ( nHeight * ::nVertRes() / ( ::nVertSize() / 25.4 ) ) )
endif
if nWidth <> 0
nWidth := Max( 0, ( nWidth * ::nHorzRes() / ( ::nHorzSize() / 25.4 ) ) )
endif
return { nWidth, nHeight }

defined values :

1. text-row = aODat[64]
left border to the 1. label = aODat[65]
2. text-row = aODat[66]
3. text-row = aODat[67]
4. text-row = aODat[68]
5. text-row = aODat[69]
label-width = aODat[70] // labels next to each other )
text centered YES / NO = aODat[74] ( images are allways shown centerd )
image YES / NO = aODat[75]
Image-top = aODat[76]
Image-size = aODat[77]

nILeft := 260 // used a fixed value

tested left border + dlabel-distance / 2 to calculate the center of the 1. label

nILeft := Max( 0, ( aODat[65] * oPRINT:nHorzRes() / (oPRINT:nHorzSize() / 25.4 )) - oPRINT:nXoffset ) + ; // left distance
Max( 0, ( ( aODat[70] * oPRINT:nHorzRes() / (oPRINT:nHorzSize() / 25.4 )) - oPRINT:nXoffset ) / 2 ) // label center

INPUT



PRINTPREVIEW





could the centered image-position be calculated ?

[Antonio Linares]

Uwe,

> but the calculation ( pixel ) to center the images doesn*t work for any reason

How are you painting them ?

[ukoenig]

Antonio,

the complete print-function
I can use it, to create a standalone sample

The final result of the calculations ( text works fine )
( I still have to check the 1. image start-position < money.bmp > )



NOT the same size :

// Text-labelwidth OK
nLablWidth := aODat[70]
// Image-labelwidth to long
nImgWidth := Max( 0, ( aODat[70] * oPRINT:nHorzRes() / (oPRINT:nHorzSize() / 25.4 )) - oPRINT:nXoffset )

More tests trying to CALCULATE images centered

I tested the different functions of class PRINTER

before I added the needed values to center the images
on 7, 9 and 4 label-solutions
but impossible to convert the text-values to pixel-values
NO function returns the needed values

how to calculate the text-values to pixel ?

Text---to---Pixel ( used fixed tested values )
3.8----------896 ( needed results for image-distance )
3.1----------730
6.0----------1420

I created a extra image to adjust to centered

Code: Select all  Expand view

IF nStyle = 7 // Labels
   nILablWidth := 896  
   //          Text =>   1.6          3.8
   //                   nLablBord + ( nILablWidth / 2 ) - ( Imagesize / 2 )
   nImgLeft          := 310     +     448               -    aODat[99] / 2 // Pixel centered  
ENDIF
IF nStyle = 9 // Labels
   nILablWidth := 730
   //         Text =>   1.0           3.1
   //                  nLablBord + ( nILablWidth / 2 ) - ( Imagesize / 2 )
   nImgLeft         := 170     +     365               -   aODat[99] / 2 // Pixel centered  
ENDIF
IF nStyle = 4 // Labels
   nILablWidth := 1420
   //        Text =>   3.0           6.0
   //                 nLablBord + ( nILablWidth / 2 ) - ( Imagesize / 2 )
   nImgLeft        := 630     +     710               -   aODat[99] / 2 // Pixel centered  
ENDIF

TPrinter object methods SayText() and PrintImage() automatically do all the calculations and center text (or multiline text) and images within given rectangle. Not only center, they can also optionally align the text/image to any of the 8 sides (4 sides and 4 corners of the given rectangle optionally. In the recent versions we can specify any units for the rectangle. There are also commands which make calling these methods easy.

If you still want to do all these calculations yourself, it is upto you.

Mr. Rao

all values are defined to print the text on a selected position
The image-positions ( values ) must be calculated in relation to the textposition
because printing images, pixel-values are needed.

The image-positions can be adjusted to any margins lines and text.
