Hi!
I am writing a scanner backend using sane. I got the datas from scanner.
And when I save this as pnm and load the file using
gdk_pixbuf_new_from_file("file.pnm") I can draw the image in a
GtkDrawingArea. But when using gdk_pixbuf_new_from_data using the datas
from memory it does not work
Here my code:
if (sane->images != NULL) {
pixbuf =
gdk_pixbuf_new_from_data((const guchar *) sane->images[0].
datas,
GDK_COLORSPACE_RGB,
FALSE, 8,
sane->images[0].width,
sane->images[0].height,
2528, NULL, NULL);
DBG(DBG_proc,
"main::preview_expose():" "\n\tn_channel: %d"
"\n\thas_alpha: %d" %"\n\tbits_per_sample: %%d"
"\n\trowstride: %d", %gdk_pixbuf_get_n_channels(pixbuf),
gdk_pixbuf_get_has_alpha(pixbuf),
gdk_pixbuf_get_bits_per_sample(pixbuf),
gdk_pixbuf_get_rowstride(pixbuf));
}
gdk_draw_pixbuf(widget->window,
widget->style->fg_gc[GTK_WIDGET_STATE(widget)], pixbuf,
0, 0, 0, 0, 400, 400, GDK_RGB_DITHER_NONE, 10, 10);
Infos about the PNM from scanner:
depth: 1;
pixels_per_line: 2528;
bytes_per_line: 316
length complete: 1108844 0
lines complete: 3509
byte heigth complete: 438
