Watermark AutoSize

[anovy]

Hi,
If I good understand, for the text watermarks the auto sizing (fit the watermark to page) is achieved by setting the nFontSize parameter to 0. However I cannot find in the documentation how to achieve similar auto sizing for the image watermarks.

And another question:
How I can for image watermarks switch off "keeping of aspect ratio"?

Hello Anovy,

Looking at the documentation - you need to specify the dwWidth, dwHeight for an image based watermark - and the image will be stretched to fit the specified area, and will keep it's aspect ratio. Sorry - it seems there is no way to make it "auto Size" by default and for all different page sizes, nor to turn off the "Keep aspect" - but I will double check that with my colleagues.

Best,
Stefan

I'm asking because XChange printer allows this - see the Properties dialog, Edit image watermark - here are options 'Keep aspect ratio' and 'Fit to page' (i.e. auto size). All other options refer to some parameter in the AddImageWatermark method, however these two not.

There are two flags

Code: Select all

#define WATER_AX_IMAGE_FIT				0x0100
#define WATER_AX_IMAGE_NO_KEEP_ASPECT	        0x0200

if WATER_AX_IMAGE_FIT is specified in dwFlags passed to AddImageWatermark, watermark will fit the page (the same effect can be reached passing 0 as width or height)
Flag WATER_AX_IMAGE_NO_KEEP_ASPECT turns off keeping aspect ratio for the image.

Thanks Ivan, all these options work perfectly as described. Will you document them?

Hi anovy,

I will speak with Ivan, and if there isn't any reason why these shouldn't be publicly announced - you can be sure we will add them in the documentation.

Best,
Stefan
