Hi all, Sorry to bother you with my problems but I am experiencing a new probable bug: I am trying to manage with data that are set as follow: P;P;P;P;...... Where P is a rgb pixel (10 bits per components) packed on an uint32 as follow: 00RGB;00RGB;00RGB;00RGB........ I mean there is two bits unused on each 32 bits pixel. So I tried to set up a view using packed_pixel and a bug occurs when using copy_and_convert_pixels... The very strange thing is that it is working when using color_convert on two pixels... I think there may exist something I didn't understood... Anyway, I give you the buggy code: /// 10 bits rgb packed to uint32_t starting at the 2nd bit typedef const packed_channel_reference rgb10_packed_channel0_t; typedef const packed_channel_reference rgb10_packed_channel1_t; typedef const packed_channel_reference rgb10_packed_channel2_t; typedef mpl::vector3 rgb10_packed_channels_t; typedef packed_pixel rgb10_packed_pixel_t; typedef view_type_from_pixel::type rgb10_packed_view_t; // image data of dimension: {w,h} = {1,0} uint32_t *data=new uint32_t[1]; data[0] = 0xFFFFF00C; rgb10_packed_view_t vw10 = interleaved_view( 1, 0, (rgb10_packed_pixel_t*)( data ), sizeof( uint32_t ) ); rgb10_packed_pixel_t pix10 = *vw10.row_begin(0); rgb16_pixel_t pix16; // This is working color_convert(pix10, pix16); std::cout << "Right {R,G,B}={" << get_color(pix16, red_t()) << "," << get_color(pix16, green_t()) << "," << get_color(pix16, blue_t()) << "}" << std::endl; // Assert that are ok assert( get_color( pix16, red_t() ) == 0xFFFF ); assert( get_color( pix16, green_t() ) == 0xFFFF ); assert( get_color( pix16, blue_t() ) == 0x00C0 ); rgb16_image_t img16(vw10.width(), vw10.height()); rgb16_view_t vw16(view(img16)); // This isn't working with packed_view copy_and_convert_pixels(vw10, vw16); pix16 = *vw16.row_begin(0); std::cout << "Wrong {R,G,B}={" << get_color(pix16, red_t()) << "," << get_color(pix16, green_t()) << "," << get_color(pix16, blue_t()) << "}" << std::endl; // Assert that doesn't pass assert( get_color( pix16, red_t() ) == 0xFFFF ); assert( get_color( pix16, green_t() ) == 0xFFFF ); assert( get_color( pix16, blue_t() ) == 0x00C0 ); Hope this will help, Eloi.
