Initialize PDF to image conversion by supplying a file path
Convert a specific page of the PDF to Image/Base64/Buffer by supplying a file path
fromPath(filePath, options)(page, convertOptions)
Converts PDF to Image/Base64/Buffer by supplying a file path
fromPath(filePath, options).bulk(pages, convertOptions)
pages
to -1
to convert all pagespages
also accepts an array indicating the page number e.g. [1,2,3]

Set GraphicsMagick's subclass or path
fromPath(filePath, options).setGMClass(subClass)
NOTE: should be called before calling convert()
or bulk()
.

Initialize PDF to image conversion by supplying a PDF base64 string.
Convert a specific page of the PDF to Image/Base64/Buffer by supplying a base64 string:
fromBase64(b64string, options)(page, convertOptions)
Functions same as fromPath(filePath, options)(page, convertOptions)
only input is changed.
Converts PDF to Image/Base64/Buffer by supplying a base64 string:
fromBase64(b64string, options).bulk(pages, convertOptions)
Functions same as fromPath(filePath, options).bulk(pages, convertOptions)
only input is changed.
Set GraphicsMagick's subclass or path:
fromBase64(b64string, options).setGMClass(subClass)
fromPath(filePath, options).setGMClass(subClass)
only input is changed.Following are the options that can be passed on the pdf2pic api:
option | default value | description |
---|---|---|
quality | 0 | Image compression level. Value depends on format , usually from 0 to 100 (more info) |
format | 'png' | Formatted image characteristics / image format (image characteristics, image format) |
width | 768 | Output width |
height | 512 | Output height |
preserveAspectRatio | false | Maintains the aspect ratio of the image. When set to true and both width and height are specified, they are interpreted as the minimum width and minimum height, respectively. If set to true with only the width specified, the height will be automatically determined while preserving the aspect ratio, and vice versa. |
density | 72 | Output DPI (dots per inch) (more info) |
savePath | './' | Path where to save the output |
saveFilename | 'untitled' | Output filename |
compression | 'jpeg' | Compression method (more info) |
option | default value | description |
---|---|---|
responseType | image | Response type of the output. Accepts: image , base64 or buffer |
The parameter can also be a boolean, if true
then the response type will be base64
and if false
then the response type will be image
.
This is deprecated and will be removed in the next major version.
