Using this default texttoimage function:

{"26"|texttoimage('a_d_mono')}

Is there anyway I can access the generated image, and filter it with settings stored in image.ini?

I cant figure out how to fetch an instance of, lets say, 'small' version of the newly generated <i>26</i> - image.

Thanks in advance for all answers.

HI Gunnar,

did you have a look at <i>/PATH/TO/Exponential/settings/texttoimage.ini</i>?

I seems that the image is stored once in a given size. If you need more versions you could make your own textToImage operator where you add code to store versions of the image.

Cheers

Hi:)

I was, as allways, hoping to avoid any customizing here. Seems this may be the only option available or not?

attribute(show) on the new object gives me the following.

filepath string 'var/cache/texttoimage/imagetext/7/c/f/7cf88a5bc61094113c35b80a3472b70a' 
filename string '26.png' 
width integer 195 
height integer 170 
alternative_text string 26 
imagepath string 'var/cache/texttoimage/imagetext/7/c/f/7cf88a5bc61094113c35b80a3472b70a/26.png'
has_size boolean true

Does anyone know if its possible to put an imagemagick filter on this image with the information provided by its attributes?

[SOLVED]

In short i wanted to create google_maps pins in .png format dynamically. So on my way there i stumbled upon an example, http://issues.ez.no/IssueView.php?Id=1689&activeItem=7, in our issue tracker</a> which led me in the right direction.

Anyway, in case someone wonders, heres my code for it.

{def $my_gmap_png_filepath= image( 'my_new_image', imagefile( 'path_to_the_background_image' ),       		array( 'text_layer_on_my_new_image'|texttoimage( 'my_custom_texttoimage_font' ),
                hash( 'halign', 'center',
                'valign', 'middle',
                'y', 6,
                'x', 1 ) ) ).filepath}

Kaping!
