Just trying to get a handle on this font business. Is there a limit on the max horizontal and max vertical pixels for a "character", ie, could you define a whole 128 x 64 pixel "character" and call it using a font number? |

128 x 64 is certainly OK. I don't know what the limit is in MMBasic. In FontTweak, I don't allow you to double the size if it is already over 128 pixels wide. I haven't put a limit when creating a new font. As long as the width X height is a multiple of 8. Provided you don't have too many characters in the font, you should be able to have large characters. An alternative might be to have smaller characters and use a font size of 2 (or 3) to display one character full screen. VK7JH MMedit MMBasic Help |

Still plugging away... 
From the Edit menu - Character from Image opens a file selector to import a BMP, JPG or PNG image. The size of the image is not important but its proportions is. If your font is 32 x 50, the image width to height should be in the same ratio. The image opens in a new window with the original one the left and a black and white version on the right. There are two methods used for converting the image. Threshold changes each pixel to white if it is brighter than the set value, black otherwise. This mode is best for line art or silhouettes. Region threshold set the pixel white if it is brighter than the surrounding pixels. This mode is usually best for true photos but you may need to experiment. To switch between the two modes, press the space bar. To adjust the threshold level, use the right and left arrow keys To adjust the size of the region (only in Region threshold mode), use the up and down arrow keys. To transfer the image to the current font character, press return or enter. Once transferred, some touch-up is usually needed. 2016-03-14_045530_FontTweak.zip The help file has been updated. Enjoy.

Hi Jim, Your 'app' has now become a very professional tool to use - this is absolutely excellent. 
In the manual there are IMHO just two things 'missing' for completeness. 1> Double Size feature. Just add a sentence explaining what the 'limit' is. 2> For the 'photo import'; show a screenshot of the 'Regional' mode. For anyone using TFTs, but has not yet tried this 'app', I strongly recommend you give it a play. Simple animations are now very easy, as well as the ability to display just about anything you want in terms of fonts & characters.

@TassyJim, Found one little bug (I think). Can be reproduced here if I follow these steps: 1> Created a new 128 x 128 font with two chrs(32 & 33). Saved, and worked just fine. Closed your app. 2> Re-Opened your app, and pulled in this BAS file just saved. 3> Added two 'empty' chrs(34 & 35) with Ctrl-N (twice) 4> Then deleted the last two chrs(34 & 35) with Ctrl-X. GET message do you wish to save. 5> Selected Yes, then File, Save BAS and in the 'file explorer' window I selected the same file name 6> File saved ok. BUT now I can't exit your app via File, Quit (or via the MS Windows 'X' button in top right corner of your app). Note: If I select File, New, (from the above scenario) then I am able to quit (otherwise it's the Task Manager needed!) On Win10 Also: Can the 'X x Y' parameters printed on the screen have a space added between the X-dimension and the 'x' (times) character 
e.g. Currently shows '128x 128' and suggesting here '128 x 128' is 'neater' 
Let me know if you're able to recreate the 'lock out'! WW For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

Hi Jim, I love FontTweak.Opens up many possibilities which would have been previously too hard. Would it be possible in the next version to preserve the font number currently used when opening up a BAS file for edit. It seems to save them all as Font#8. Thanks Gerry Latest F4 Latest H7 |

That should be easy to do and makes a lot of sense. I might make it something that can be set by the user. Jim VK7JH MMedit MMBasic Help |

Hi Jim, Thanks. One more thing would be good. I wanted to modify a font to add the lower characters 1-31. I eventually managed to add the correct number of 0000s at the start of the file and adjust the header, but took a bit of fiddling. The option to add a character before the current first character would be very useful as well. Regards Gerry Latest F4 Latest H7 |

Hi Jim, I have discovered a small issue with FontTweak when it saves a font which does not coincide with a neat set of 8 characters at the end. The font works only if it is the last thing in the basic program and I have used it like that up until now, but I have also found it wont go with LIBRARY SAVE so have had to track it down. It looks like MMBasic and the SAVE LIBRARY want it padded out to a neat 8 characters. I have added 00 at the end of this font file and MMBASIC is happy. If I open with FontTweak and save it, FontTweak saves the correct number of bytes as need for the font, but we need to pad it out the make MMBasic happy. Its not a big thing once you know, but a bit hard to find.

Hey Font Tweaker's... Probably a simple question... (newbe type)... I have a complete 95 character set loaded, and want to save just the numbers... Getting rid of the ending characters went OK (delete last command) but I can't seem to find a way to remove the proceeding ones... I am sure it's easy, but I can't seem to find the command to do it...  Must have missed it somewhere...  |

Save your file as C type. Open it in your preferred text editor. In the C format, each character occupies one line so you can delete the character you don't want. Deleting from the start or end is OK. If you delete from the middle, the character ASCII values will get out of step. Once you have deleted the unwanted characters, you need to edit the first line of the definition The 4 HEX values are font width, font height, first character ASCII value, number of characters. You will need to change the first character value and the number of characters. Save the file and open it in FontTweak. Save as BAS Jim VK7JH MMedit MMBasic Help |

Thanks Jim..! I knew if I "messed" with the "C" code, those numbers would be different somehow and I figured the program generated them, so cutting stuff out would screw things up... Will give it a go tomorrow after work..  |
