- SYNOPSIS
- Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap )
+bool wxBitmap::SaveFile( const wxString &name, wxBitmapType type,
+ const wxPalette *palette ) const
+{
+ wxCHECK_MSG( Ok(), false, wxT("invalid bitmap") );
- DESCRIPTION
- This function creates a grayed-out copy of the argument pixmap, suitable
- for use as a XmLabel's XmNlabelInsensitivePixmap resource.
+ wxBitmapHandler *handler = FindHandler(type);
- RETURN VALUES
- The return value is the new Pixmap id or zero on error. Errors include
- a NULL display argument or an invalid Pixmap argument.
+ // Try to save the bitmap via wxImage handlers:
+ if (handler == NULL)
+ {
+ wxImage image(this->ConvertToImage());
+ if (image.Ok()) return image.SaveFile( name, type );
- ERRORS
- If one of the XLib functions fail, it will produce a X error. The
- default X error handler prints a diagnostic and calls exit().
+ return false;
+ }
- SEE ALSO
- XCopyArea(3), XCreateBitmapFromData(3), XCreateGC(3), XCreatePixmap(3),
- XFillRectangle(3), exit(2)

-Hi Julian,
+void wxBitmap::SetHeight( int height )
+{
+ if (!m_refData) m_refData = new wxBitmapRefData();
-I've been working on a wxWin application for image processing. From the
-beginning, I was surprised by the (lack of) speed of ConvertToBitmap,
-till I looked in the source code of image.cpp. I saw that converting a
-wxImage to a bitmap with 8-bit pixels is done with comparing every pixel
-to the 256 colors of the palet. A very time-consuming piece of code!
+ M_BMPDATA->m_height = height;
+}
-Because I wanted a faster application, I've made a 'patch' for this. In
-short: every pixel of the image is compared to a sorted list with
-colors. If the color is found in the list, the palette entry is
-returned; if the color is not found, the color palette is searched and
-then the palette entry is returned and the color added to the sorted
-list.
+void wxBitmap::SetWidth( int width )
+{
+ if (!m_refData) m_refData = new wxBitmapRefData();
-Maybe there is another method for this, namely changing the palette
-itself (if the colors are known, as is the case with tiffs with a
-colormap). I did not look at this, maybe someone else did?
+ M_BMPDATA->m_width = width;
+}
-The code of the patch is attached, have a look on it, and maybe you will
-ship it with the next release of wxMotif?
+void wxBitmap::SetDepth( int depth )
+{
+ if (!m_refData) m_refData = new wxBitmapRefData();
-Regards,
+ M_BMPDATA->m_bpp = depth;
