Infro,
  
      i think you were right. I printed the following info.

dpi = 200 pointsize = 16 ROWS = 35, width = 28, pitch = 28 Stride = 28 num_grays = 256
dpi = 300 pointsize = 16 ROWS = 52, width = 43, pitch = 43 Stride = 44 num_grays = 256
dpi = 300 pointsize = 12 ROWS = 40, width = 32, pitch = 32 Stride = 32 num_grays = 256

as we can see for second one width and stride are different.
How can this be tackled ?


Thanks
Varun

i didn't understood fully what you said,

i am creating the cairo surface of same width and heigth as

               int stride = cairo_format_stride_for_width(CAIRO_FORMAT_A8, bitmap->width); 
               cairo_surface_t *surface  = cairo_image_surface_create_for_data(bitmap->buffer, CAIRO_FORMAT_A8,
                                                               bitmap->width, bitmap->rows, stride);
                cairo_surface_write_to_png(surface, "A.png");


Thanks

If I had to take a guess, I would say that the 16pt @ 300dpi was copied/drawn incorrectly, specifically, that the source data had a smaller width than the destination, and that created the "slanted" effect.

As from my sample, the 12 starts in the top right corner and proceeds to the bottom left corner, which is my guess.
ex.
(source is 1-8, desitnation is 1-0)
1234567812
