- SYNOPSIS
- Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap )
+ wxCHECK_MSG( x_image, wxNullImage, wxT("couldn't create image") );
- DESCRIPTION
- This function creates a grayed-out copy of the argument pixmap, suitable
- for use as a XmLabel's XmNlabelInsensitivePixmap resource.
+ image.Create( GetWidth(), GetHeight() );
+ char unsigned *data = image.GetData();
- 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.
+ if (!data)
+ {
+ XDestroyImage( x_image );
+ wxFAIL_MSG( wxT("couldn't create image") );
+ return wxNullImage;
+ }
- 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().
+ XImage *x_image_mask = NULL;
+ if (GetMask())
+ {
+ x_image_mask = XGetImage( xdisplay, (Pixmap) GetMask()->GetBitmap(),
+ 0, 0,
+ GetWidth(), GetHeight(),
+ AllPlanes, ZPixmap );
- SEE ALSO
- XCopyArea(3), XCreateBitmapFromData(3), XCreateGC(3), XCreatePixmap(3),
- XFillRectangle(3), exit(2)
+ image.SetMaskColour( 16, 16, 16 ); // anything unlikely and dividable

-Subject: Patch for Motif ConvertToBitmap
-
-Hi Julian,
-
-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!
-
-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.
-
-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?
-
-The code of the patch is attached, have a look on it, and maybe you will
-ship it with the next release of wxMotif?
-
-Regards,
-
