Draw Text on an Image. Help!

[rikshawdriver]

Hi all,

1. Can I create and Save pictures (JPG or GIF) from VB ?

2. I have a textbox with some special fonts and Text attributes. Can I incorporate the text from this textbox with its visual properties to an existing image?

Any help will be highly appeciated.

Thanks

To convert a picturebox to a .bmp

SavePicture Picture1.Picture "myfile.bmp"

If you need a full range of formats, use the Kodak ImgEdit control that ships with VB. It has a SaveAS method that allows a big range of output graphics file formats.

To put text on a graphical control - here is an example from www.allapi.net. You use the hDC property of the graphical control. This example uses a form. Substitute the hDC (handle to the device context) for whatever grpahical control you decide to use.

Const DC_ACTIVE = &H1
Const DC_ICON = &H4
Const DC_TEXT = &H8
Const BDR_SUNKENOUTER = &H2
Const BDR_RAISEDINNER = &H4
Const EDGE_ETCHED = (BDR_SUNKENOUTER Or BDR_RAISEDINNER)
Const BF_BOTTOM = &H8
Const BF_LEFT = &H1
Const BF_RIGHT = &H4
Const BF_TOP = &H2
Const BF_RECT = (BF_LEFT Or BF_TOP Or BF_RIGHT Or BF_BOTTOM)
Const DFC_BUTTON = 4
Const DFC_POPUPMENU = 5            'Only Win98/2000 !!
Const DFCS_BUTTON3STATE = &H10
Const DT_CENTER = &H1
Const DC_GRADIENT = &H20          'Only Win98/2000 !!
