ConvImgs is an application that allows the batch interconversion of various image filetypes, e.g. sprite, PNG, JPEG, with the bonus that a number of simple transformations can be carried out at the same time.
While ConvImgs is under continuous development, this help manual may not keep up with developments. It should be correct for the development version shown in the header to this page.
For a new installation, simply drag and drop the ConvImgs application into the directory of your choice.
If you have a previous copy of ConvImgs you have two choices.
ConvImgs is run in the usual way by double clicking on its icon. It will install on the icon bar.
The file, or selection of files, to be converted should be dragged to ConvImgs, either to the iconbar icon, when the control window will open, or if the control window is already open, files may be dragged to it.
The selection of files can be added to by dragging further selections. In addition, if one or more folders are dragged, then ConvImgs will add any suitable image files in the folder to the list.
ConvImgs will NOT recurse down the directory structure, only suitable image files in the top level will be added to the queue for processing. This is a deliberate decision - the worst case scenario with full recursion is that every image file on your 200GB drive is converted to eg. PNG format!
For any particular batch process, the types of the files to be converted need not be all the same - ConvImgs will queue for processing any image type it is able to load. It is currently able to load the following filetypes.
If a selection of suitable image files is dragged to the iconbar icon, these files will be added to the list of files to be processed. The control window will open automatically if not already open.
Clicking with SELECT on the iconbar icon will open the control window.
The control window is shown below.
In the top section is shown information about the selection of files waiting to be converted.
The middle section of the window allows a number of standard transformations to be applied. In this version there are three types of transformation options.
These are described in detail below.
At the bottom of the window are the settings for the saving of the converted files.
This allows the output filetype to be set. The JPEG quality may be set, for when saving as JPEG files. The SET button should be clicked to apply the new settings.
At the bottom left of the control window is the Save settings button. Clicking this button will save all the current settings so that they will be remembered over a restart. This excludes the file list and the save path.
At the bottom right of the control window is the Convert button. Clicking this button will start the conversion process, assuming there are files waiting in the queue. The control window will close, and the status window will open. This is described below.
The options available are
There are currently four options for resizing.
If the option 'Allow scale up' is ticked, then the images will be scaled up if necessary to fit the size, otherwise images smaller than the set dimensions will be left as is. This setting applies only to the last three options. If the 'Resize by' value is greater than 100%, then this will always be honoured.
The SET button should be clicked to apply the new settings.
Various levels of sharpening or blurring are available. The option 'Slight sharpen' is probably the one to use to reduce the softness of digital camera images.
When the Convert button is clicked, assuming there are some files in the queue, the control window will close, and the status window will open. This is shown below.
There are four display fields which show the progress of the processing. The total number of files to process, and the position in the queue of the current file are shown. The filename of the current file is also shown. There is also a field that shows the current operation being carried out.
If this window is expanded to full size, you will find two buttons at the bottom to allow some control over the processing.
The Choices... window, accessed from the iconbar icon menu, is shown below.
The additional option Long extension will use eg jpeg instead of jpg, where such alternative extensions exist.
At the bottom of the window are three action buttons.
