gdiplus.lib It's in the BCC PSDK folder.

Thanks.

Antonio,

FYI

I found a GDIPLUS.LIB in de library of xHarbour Professional. It has a date in 2015.
Can it be used?

[nageswaragunupudi]

Are you using xHarbour professional?

If you are using normal xHarbour or Harbour, GDI+ functionality is already built-in to FWH
Please let me know clearly your xHarbour/Harbour version and your requirement.

[driessen]

Mr. Rao,

I only use xHarbour Professional for debugging reasons.
For the versions which I give to my customers, I always use Harbour.
And for Harbour, these files are needed.

[nageswaragunupudi]

You must be already linking \harbour\lib\psdk\gdiplus.lib.
Without linking you can not link any harbour application.
All your applications are already using GDI+ , but you may not be aware of it.
You do not need to do anything extra now.

Just try ximage02.prg and ximage01.prg in samples folder.
By rotating mousewheel you can zoom and unzoom the images.

Please let us know your exact requirement and we will suggest appropriate functions.

Mr. Rao,

Using a combination of FWH and macros in Word, I turn each page into a PNG file which is saved on my disk. Then I start a blank Word document, then these PNG-files are opened one by one, after which they are pasted in the blank Word document.

Then a new Outlook message is created, the PNG-files in the Word document are copied to the Outlook message.

The result is that the correspondent can read the text immediately instead of having to open another attachment.

I establised all this in FWH and it really works very well.

I only need to paste the PNG-files into a bigger format.
And I'm looking for a solution to realize that.

Thank you.

Enlarging an image.

Code: Select all | Expand

aImage := FW_ReadImage( nil, cOriginalFile, { nNewWidth, nNewHeight }, .t. )
FW_SaveImage( aImage[ 1 ], "zoomed.png" )
PalBmpFree( aImage )

Mr. Rao,

THanks a lot for your suggestion.

After line 2 I got an error : "Invalid image".

Another problem: in the first line there are nNewHeight and nNewWitdth.
But I need to know the height and width of the original image first.
Then I have to calculate the new value by adding a percentage.

How can I establish that?

Thanks

Please copy this program to your fwh\samples folder and try building with buildh.bat and buildxhb.bat
