Vips.Image.wio_input (original) (raw)

Method

VipsImagewio_input

Declaration [src]

int
vips_image_wio_input (
  VipsImage* image
)

Description [src]

Check that an image is readable via the VIPS_IMAGE_ADDR() macro, that is, that the entire image is in memory and all pixels can be read withVIPS_IMAGE_ADDR(). If it isn’t, try to transform it so that VIPS_IMAGE_ADDR() can work.

Since this function modifies image, it is not thread-safe. Only call it on images which you are sure have not been shared with another thread. If the image might have been shared, use the less efficientvips_image_copy_memory() instead.

Return value

Type: int

0 on success, or -1 on error.
