Oh, no!. There are different layers created for different images. The
problem comes when i close the first image, and open a new image; then i
create this new image, create the new layers and associate these new layers
to the new image, but when i try to get the image ID from one of these new
layers, it returns -1. If i don't close the first image it works fine (with
both images opened).
my load -gimp relevant- code:
image = gimp_image_new (50, 50, GIMP_GRAY);
...
for (i = 0; i < dataset_num_rasterbands; i++) {
...
get_band_data (&band[i], GDALGetRasterBand(dataset, i + 1), image,
layer_number); /* rasterband count starts in 1 */
gimp_image_add_layer (image, band[i].layer_id, i);
...
}
gimp_image_resize_to_layers (image);
gimp_display_new (image);
and the get_band_data code:
band->layer_id = gimp_layer_new (image, band->colorspace_name,
band->width, band->height, GIMP_GRAY_IMAGE, 100.0, GIMP_NORMAL_MODE);
drawable = gimp_drawable_get (band->layer_id);
gimp_pixel_rgn_init (&pr, drawable, 0, 0, band->width, band->height,
TRUE, FALSE);
...
gimp_pixel_rgn_set_rect (&pr, scaled_data, 0, 0, drawable->width,
drawable->height);
gimp_drawable_flush (drawable);
gimp_drawable_detach (drawable);
That's all.
