PS_PLACE_IMAGE(3) 1 PS_PLACE_IMAGE(3)ps_place_image - Places image on the pageSYNOPSIS
bool ps_place_image (resource $psdoc, int $imageid, float $x, float $y, float $scale)
DESCRIPTION
Places a formerly loaded image on the page. The image can be scaled. If the image shall be rotated as well, you will have to rotate the
coordinate system before with ps_rotate(3).
PARAMETERS
o $psdoc
- Resource identifier of the postscript file as returned by ps_new(3).
o $imageid
- The resource identifier of the image as returned by ps_open_image(3) or ps_open_image_file(3).
o $x
- x-coordinate of the lower left corner of the image.
o $y
- y-coordinate of the lower left corner of the image.
o $scale
- The scaling factor for the image. A scale of 1.0 will result in a resolution of 72 dpi, because each pixel is equivalent to 1
point.
RETURN VALUES
Returns TRUE on success or FALSE on failure.

nents, int $bpc, string $params)
DESCRIPTION
Reads an image which is already available in memory. The parameter $source is currently not evaluated and assumed to be memory. The image
data is a sequence of pixels starting in th upper left corner and ending in the lower right corner. Each pixel consists of $components
color components, and each component has $bpc bits.
PARAMETERS
o $psdoc
- Resource identifier of the postscript file as returned by ps_new(3).
o $type
- The type of the image. Possible values are png, jpeg, or eps.
o $source
- Not used.
o $data
- The image data.
o $length
- The length of the image data.
o $width
- The width of the image.
o $height
- The height of the image.
o $components
- The number of components for each pixel. This can be 1 (gray scale images), 3 (rgb images), or 4 (cmyk, rgba images).
o $bpc
- Number of bits per component (quite often 8).
o $params
-
RETURN VALUES
Returns identifier of image or zero in case of an error. The identifier is a positive number greater than 0.
