Folder and file structure for HTML, styles and scripts
For the use of HTML templates to place content, in this example we see folders and files for the fonts, scripts and styles used (each of which is optional), as well as the obligatory index.html. The content in the Temp files folder is updated every run:
- The HTMLTemplates folder will be created by the pdfToolbox in the folder for the callas pdfToolbox version currently in use, under Repositories/Custom/Folder with a time stamp.
- This will include - depending on the library - a number of predefined examples such as “Add colorbar - cmyk”. It will include the following folders and files:
- The fonts folder, containing all fonts required for the HTML template,
- The index.html file which is required in all cases,
- The styles folder for CSS files.
Naturally, the folder names for “fonts”, “scripts” and “styles” can be changed depending on the template.
After the first run using a given HTML template, pdfToolbox will create the callas_temp folder.
This folder contains temporary files and will be recreated each time the Fixup is run.
The following files will be included here: “calsDocInfo.js” (contains information regarding the running of the “Place content” Fixup; see Use information about the PDF document); the index.pdf file (the PDF content generated using the HTML template); and pdfChip.log (a log file).
Important: The user can create folders for their own Place Content Fixups using any name, such as an “images” folder for images. These folders must be referenced within index.html to allow pdfToolbox to access them.
Supplied examples for “Place content on page” using HTML templates
callas software supplies a number of “Place content on page”-type Fixups with the standard version of pdfToolbox which use HTML templates.
This includes three Fixups for adding color bars in CMYK, grayscale and spot colors, as well as Fixups for dimension arrows (GitHub link), document names, fold marks (letter) (GitHub link), job ID (GitHub link) and registration marks (GitHub link).
Add additional content: PDFs or Images on PDF
The "Place content on page" Fixup also gives you the possibility to place an image or a PDF file on the page - all without a full HTML template.
- Under Folders, you can select the folder containing all HTML files, styles and scripts required to use HTML templates. The folders shown in the image below are supplied as standard. Click on Open folder with configuration files to view the corresponding location within the file system.
2. Add a new folder, for example "Add PDF". Then you can copy any PDF or image file to this folder.
3. After the Fixup is closed and reopened, the new "Add PDF" folder appears in the dropdown menu. Now the PDF or image can be placed on the page.
